Anybody come across a car charger that is high current like the HTC wall charger?
Most car chargers are classified as "rapid".
Anything designed to charge an iPad (2.1A versus the typical 1A) will give you plenty of juice. I use the Scosche reVIVE II with Pandora, Bluetooth, and GPS Navigation all on and still have enough power to positively charge my battery.
Fair warning, though, this will cause the phone to get real hot (I've had the overheating warning lights flash twice so far), so make sure you have plenty of ventilation around the phone, keep it out of the sun, etc etc.
Any charger that is at least 1 amp. will do. The phone 'pulls' a max of around 0.85 amps. No need for more then 1 amp.
If it has a replaceable cable, it must be the heaviest gauge, shortest cable, that you can use. I have seen long cheap thin cables that drop over a volt, and the Thunderbolt charges really slowly.
The charger or cable have to state that they for rapid charging. To rapid charge, you need to have the USB D- and D+ lines shorted. If that are not shorted, the Thunderbolt limits the charge current to around 0.35 amps. thinking it is connected to a PC. If they are shorted, letting the Thunderbolt know it can be rapid charged, you get up there around 0.85. You can easily modify the charger for high rate if it is good for at least an amp.
And in the end is heat. Heat and lots of it. It will damage the battery. So put it out of the sun and in cool air like near a vent.

Review off Amazon
Genuine Motorola charger in retail packaging. 4.75-5.25V 950mA output, works w/ most micro-USB phones like Incredible, etc., June 11, 2010
By
David Pearlman "sound fanatic" (Arlington, MA) - See all my reviews
(TOP 500 REVIEWER) (VINE VOICE) (REAL NAME)
Amazon Verified Purchase(What's this?)
There are so many sketchy sellers selling phone chargers out there, that it can be a bit scary. The problem is that if the charger is poorly made, the output of the charger can be out of spec and can, in some cases, fry the phone you connect to it.
For that reason, when it comes to phone chargers, you should stick to name brands. (They are all made in China, but the name brand ones are usually subject to stricter QA).
When I found this charger on Amazon, SOLD BY AMAZON, I jumped on it. It's a MICRO USB car charger, made for Motorola and sold under the Motorola name, in retail packaging. The rated output is 4.75-5.25V and 950mA.
This charger should work fine with most any phone that uses the MICRO USB connector. The key number to pay attention to is the second one, the rated amperage. This is the MAXIMUM amount of current that the phone can request from the charger. A typical USB port on a PC provides as little as 100mA, and few provide more than 500mA. So this charger should charge your phone faster than when it's connected to a PC. A few phones out now can use up to 1000mA. But that just means they CAN use that amount. If 950mA is provided, they'll still charge, just a bit more slowly.
Note that the amperage (second number) merely tells you how much the charger CAN supply, if requested. The phone itself is responsible for asking for the current. That is to say, if this charger can provide 950mA, but your phone can only use 300mA--no problem. Your phone asks for 300mA and the charger provides all of what is requested. If, on the other hand, your phone can use 1000mA, this charger will provide all it can, which is 950mA--a wee bit less than the max asked for. That's also not a problem; it just means your phone will charge a little bit (not much in this case) more slowly. The rated voltage for this charger is presented in a range of 4.75-5.25V. The "ideal" voltage for a USB charger of any type if 5V. And most chargers for home use are rated right at 5V. But car chargers work in a noisier environment and thus you have the range. This is where a cheapo charger can really do damage, as some of them are poorly regulated and can provide voltages that are WAY out of spec. Again, when you can get a name brand charger from a seller you can trust (Amazon) for such a reasonable price, it's very foolish to consider the cheapo no-names.
This is an excellent quality name brand travel micro USB charger at a price that beats the no-name junk from third party sellers. What's not to like?
BE SURE TO ORDER IT FROM AMAZON AND NOT ONE OF THE THIRD PARTY SELLERS, as some of those have been known to make mistakes with respect to what they ship relative to the listing. I can confirm that Amazon is shipping the P513 /89143N charger, as pictured.

I've been contemplating buying this one, but I'd like to ask you if it charges your battery with navigation+music going? I have a usb charger in my truck, and with both of those going it just manages to keep my battery level where its at, sometimes losing a % or two.

From what I've read in the past here on XDA and on the reviews for the charger (on amazon) you shouldn't have a problem. The second review for the charger on amazon states that the reviewer was looking for a charger which actually charged his phone will using GPS and that he found it. It's a very well built charger and cheap. It's made my Motorola and sold by Amazon so buy with confidence.

It does indeed charge. I've had it since my original Droid and was concerned when I updated to the TB but it will charge the TB no matter what you're doing (I've had Nav running while on a phone call with BT and searching the internet and it still showed it was charging). Just be prepared for your phone to get HOT!! Great charger.

Actually, the phone will pull more than 850 mA. You're probably basing that on using a battery monitor, which only shows the flow of current into/out of the battery. I've seen 800 mA into the battery at the same time I have display, GPS and a phone call going, which is definitely more than an additional 50 mA. It wouldn't surprise me if the phone can take advantage of something more than 1A, since I see a battery drain of more than 200 mA with all of that going when not on the charger.

I have that Motorola charger and am a heavy GPS user. It charges the battery as if it were plugged into the wall. You'll be very satisfied.

No, that was measured at the 5 volt power supply, based upon a lab power supply. I did a lot of experimenting when I developed the charger and phone mount for my motorcycle. And to get the 850ma from the power supply, I used a very short, maybe 8 inch, USB cable, and a charge voltage close to 5.3 volts. With 5 volts at the power supply, it would only pull about 650ma from the power supply. That was due to the voltage drop in the USB cable. With the 5.3 volts at the power supply, I was getting close to an actual 5 volts at the Thunderbolt. I never measured the current at the battery, but I could see it being a bit more then the 850ma in, if there were a switch mode supply in there.
Though I like the Battery Monitor widget as a rough guide, I never tested to see if the battery current and the battery monitor are accurate.
Does anyone know if the included HTC ac adapter and cable will charge faster than using your pc with the included USB cable?

Absolutely.
A PC USB port is limited to under 500ma. The Thunderbolt appears to to limit PC USB draw to about 350ma. I haven't measured the actual current in the HTC charger, but it is a high current charger, and charges my Thunderbolt very quickly. Battery Monitor widget shows high battery charge rates. I suspect it is getting near the max rate up near 1 amp.

That doesn't mean much. That is the MAX the charger can output. The amount that the Thunderbolt will pull varies. If it thinks it is plugged into a USB, it will be less then 500ma. even if the charger is capable of 10 amps.

um, i am aware that any charger that will do 1A will do. that was my question, what car charger will do 1A. Alot of times, they dont have that info listed on pages that are selling them.
and the whole thing about the D- and D+ shorted together, i do not believe. the HTC cable that came with the phone does rapid charging and i use it for data all the time too. if they D- and D+ was shorted, i would not be able to use it for data transfer. not unless the HTC charger shorts them internally inside the charger.

Yes, it is hard to find the current info online or even on the package sometimes.
Yes, it is shorted in the charger. I have seen it done in the cable and the cable can't be used for data of course. Not sure why anyone would do that, but they do.
This is a review of Anker Astro E5 15000 mAh external battery: http://www.ianker.com/product/79AN15K-WA
Being familiar with footprint of their E4 battery, when Anker announced a new E5 model with higher capacity I was expecting to see bigger and heavier model with a typical 30% efficiency loss. I know I bring it up in a lot of the reviews, but labeled capacity of ANY external battery is not what your phone battery going to see. Its a total capacity of cells inside of external battery which gets converted to 5V usb interface output and then back to your cell phone battery while charging - the efficiency loss during the conversion reduces the actual capacity by approximately 30%, with some batteries close to 40% and others maybe slightly better to 25%. On top of that, a lot of no name ebay HK sellers have batteries with super exaggerated capacity where you will be lucky to get even half of what they advertise on the label. That is why I only trust a few brands, Anker being one of them.
Once I received E5 unit for review to my surprise, the footprint stayed almost unchanged and difference in weight was negligible in comparison to previous E4 gen. But you actually get 2000 mAh more in capacity to bring it up to 15000 mAh. The battery cells are changing and improving, and I'm glad to see that Anker is keeping up with a new technology. E5 external battery is not exactly feather light, but at about 11.1 oz and 5"x3"x0.9" is manageable and actually the same as Note 2 with Zerolemon battery. The exterior is solid plastic, no flex, and comes in either white or black. For this review I chose a white unit and found it to be great to cover up any fingerprints. The top has a large power button with dual functionality to also turn on built-in led light. At full charged battery capacity, the light could last up to 700 hours if you only use it for that purpose. Next to power button you have 4-led capacity/charging indicator in 25% increments. Charging input to the battery is a standard micro-usb and has 1.5A charging speed for a fast charging of this battery. Output is a dual full usb port, rated at 2A and 1A both of which can be used simultaneously to deliver 3A of combined current. Each port current output is regulated where I confirmed charging Note 2 from one gave me max 2A and from the other one only up to 1A.
This extended battery comes with usb cable and interchangeable tips for micro-usb, mini-usb, and apple 30-pin connector. Also, it comes with a convenient storage pouch for a battery, cable, and attachment. It also comes with a detailed manual and 18-month warranty card. But there is also a big surprise. I have been reading other independent test reviews of this module and it turned out to have an actual capacity close to 11,800 mAh. We are talking about 21.5% efficiency loss which is very good considering typical batteries of such capacity have it at 30% or higher. This mean you can charge your Note 2 with a standard battery almost 4 times, or easily charge Zerolemon and have some juice still left - all this at a max 2A speed. Overall, I'm very impressed with this battery and its performance!

Awesome! Thanks for this! What are you using to measure the charge that is going in to the Note 2? I have an external battery rated at 12,000mah, that has both 1A and 2A ports, and would like to see what it's actually putting out, as well as check some wall adaptors that I have. Thanks for the review! Anker is also one of the few brands that I trust as well!

I actually found it to be relatively accurate by comparing charging time versus charging percentage. Ignore "Now" value. Just look for Max/Avg as your charging currents. This app comes very handy for those without root, like myself, to measure your charging current.

Thanks!! Just tested it out. Like you said, the Now value isn't what the charging rate actually is. Took me reading some reviews on the Play Store to figure that out. The Now value is what the device recommends, while the Average value is what rate you're actually charging at.
I'm not sure how accurate it is though. While using my HTC wall chargers that came with my both my black Evo LTE and white one, the values are Maximum 900, Now 1798, and Average 900. I'm getting the same numbers while using the Samsung wall charger that came with my Note 2. I assume that 900 is correct for the HTC chargers, as they're only 1Amp chargers so I'm getting .9Amp from them. The Samsung charger is 2Amp though, so it should be twice as high as the HTC chargers.
EDIT : Just tested my 12,000mah PowerBank. I got 500 out of the 1Amp port, and 1700 out of the 2Amp port! Very happy with those numbers!! Especially it considering that it appears to be charging at a higher rate than my OEM Samsung wall charger!!!

Mike, which 12kmAh charger are you using? I know Anker stuff is universal for Apple/Android, while some other ones will drop your charging current to max 0.5A when connected to "apple" port. Another question, which usb cable are you using? Unless if its original Sammy cable that came with OEM charger or a cable like from monoprice with 24AWG/28AWG rating (thicker power wires to handle up to 3A of current), the cable itself its a bottleneck if its designed for a lower charging current. So for example, if you are using HTC charger/cable and then used their cable to connect to Samsung wall charger - you could be current limiting your phone (thinner wires, more resistance). And even if you are using OEM Samsung wall charger and cable - I noticed that in our house some outlets can't supply enough current depending on what other stuff is connected to the same shared power branch.

I think PowerBank is the brand, and Long March is the model. There is a long thread in the Evo LTE Accessories subforum (my other phone), and that's how I heard about it. I normally wouldn't buy an off brand accessory, but with many XDA members giving great feedback, and some have had it close to a year, I decided to try it out. Very happy that I did!! I looks a lot like your Anker actually. It has 2 USB ports for charging other devices, a 1 Amp and a 2 Amp, and also has a little LED flashlight as well. It works great and this app you mentioned showed me that the 2 Amp port is charging at 1.7 Amp(while using my HTC micro USB cable, so it may charge at an even higher rate using the Samsung cable), so I'm happy with that.
For the Samsung wall charger, I'm using the Samsung wall charger and Samsung micro USB cable. I do have it plugged in to a power strip though, so I'll have to try it plugged directly in to a wall outlet with nothing else plugged in. Thanks for the info!
EDIT : Update - after trying the Samsung charger in a wall outlet instead of the power strip, I'm still getting 900(.9 Amp). Maybe my charger is just not putting out the Amperage it should anymore, and I should just buy another Samsung wall charger if I want to get the correct Amperage. I rarely use my wall charger though, as I just use my external battery charger to charge my extra Samsung battery. When I do plug in the phone, it's usually in to my PowerBank while I'm sitting outside playing on my phone and drinking/smoking (never smoke in my house!).

What you refer to is Yoobao brand power bank model "Long March". Unfortunately, there is only one official reseller of Yoobao brand in US and its KeviKev (I reviewed Yoobao Thunder 13000 mAh from them before - http://kevikev.com/Samsung-Galaxy-NOTE-II-2-N7100-Cases-and-Accessories_c47.htm). Long March is 11,200 mAh model. Did you get it from Amazon or eBay? It's a Chinese knock off of Yoobao, but it doesn't matter since it works for you. They all use the same battery cells anyway, and original Yoobao stuff might be a bit more robust and have more durable plastic shell. But listen, if the one you have works - its all good and don't worry about it!!!
Strange about Samsung wall charger. Sounds like something is gone south. Btw, don't even bother buying anything labeled as "original OEM Samsung wall charger" from Amazon or eBay - it's all fake knock offs as well. For the fun I just look on Amazon reviews, and everybody complaining about Samsung OEM wall charger not even being able to supply 1A. That's a problem with Amazon, anybody can create a merchant account and list their product under original manufacturer listing. And the rest is history because you will never be able to find original Samsung part since everything else will be a fake copy But I assume you are using your original wall charger and cable which came from Samsung when you bought N2?

That explosion has nothing to do with Anker batteries. That was highly/almost 100% due to the black cheap/low amp charger. I had a random cheap black USB charger similar to that for charging low amp Emerson bluetooth headphones, which was 400 mAH output, and we charged my brother's IPAD 2 with it, and it started to smoke. Same issue happened when charging his S3 with that cheap charger. I think it was their mistake for providing such a terrible charger, which is why it seemed the white one was probably better. The lesson is: don't charge anything that has a higher capacity/requirement with something far below it's capacity - otherwise, you're just asking for a dangerous situation to occur. That's just my two cents and observation from what I have seen, read, and personally experienced
how to charge
Excellent and informative review! 2 questions (I am a novice...). How do I charge the charger...can I use either my iphone 5 plug (output 5V/1A) or ipad2 plug? And, when charging my devices, is it the 1A socket for iphone 5, and 2A socket for ipad 2? Thank you!

To charge the charger you can use any wall charger with micro-usb output. Since this is Android forum and Note 2 section, I assume you have one of those. Otherwise as you aware the charging cable for iPhone 5 is not micro-usb. But to charge your device, you can do that with any phone or tablet since charging/data cables have usb on one side (that will go into a charger) and whatever connector you are using on your device on the other side of the cable. In theory you can use either outputs.
Hello! Great review, I purchased it for 50 bucks on amazon 5 minutes ago because of the review. I am a noob, sorry in advance, I made this account to ask these two questions: 1: I just wanna use it for my iPhone 5, do i plug it in on the 1A or 2A? If both is ok, which one is better for the battery in the phone? 2: I will need an adapter, which one is better? Micro Usb to Lightning or 30pin to Lightning? I dont like the size of the 30 pin to lighting, so is it ok to purchase a micro usb to lighting instead? Does this affect anything like charging time?
Thanks for answering, have a nice day

Hello! Great review, I purchased it for 50 bucks on amazon 5 minutes ago because of the review. I am a noob, sorry in advance, I made this account to ask these two questions: 1: I just wanna use it for my iPhone 5, do i plug it in on the 1A or 2A? If both is ok, which one is better for the battery in the phone? 2: I will need an adapter, which one is better? Micro Usb to Lightning or 30pin to Lightning? I dont like the size of the 30 pin to lighting, so is it ok to purchase a micro usb to lighting instead? Does this affect anything like charging time?

You can use either 1A or 2A outputs. Your phone has a fixed charging speed and will not draw more current that it's limited to. So for example if iPhone can charger at a speed of 1A per hour and you connect it to an output that can supply 2A per hour - it will only draw at 1A per hour speed. BUT, if you have Note 2 which takes advantage of 2A per hour charging and you plug it into 1A port, it will be charging at half the speed.
Regarding cable, try to minimize number of connecting adapters. For example, you get a cable with 30pin connector and you can add 30pin to Lighting adapter to it, but with every connection you add resistance which going to affect total amount of current and can slow down the charging, etc. You want to have point-to-point cable. So I would recommend using USB to Lighting connector cable. Not micro-usb, but usb because charing ports on this external power supply are full size usb. Only the port to charge this battery is micro-usb because of a common connection with other charging cables.

I wonder if you could try something for me.
Could you find out if the Anker will supply a phone/device while it is itself being charged? Also, whether it will keep supplying the phone/device without interruption when its own charging supply is connected and disconnected?
I want to use it like a mini-UPS for my phone while charging it from my bicycle dynamo, but for this, it needs to cope with a charging supply which stops and starts, while continuing to supply any connected devices.
I think I tried it before, and it didn't work. These external battery devices are not intended to work in pass-through mode. I think there are some other ones (I'm 100% sure if that was NewTrent), but the vendor will not guarantee the device under warranty because of an additional overheating and cut of the efficiency. This will really complicate the controller of such ext battery where it has to keep balance between charging and discharging of the same battery at the same time. I'm pretty sure Anker stuff will not allow that because they have smart current monitoring functionality built-in in order not to overcharge or over-drain the device.
But it would be an interesting experiment where you connect ext battery to the outlet and to the phone. I wonder if it starts charging battery first until it's full, and then switch to charging the phone

I did just that yesterday, and it worked fine. Now, the anker would not actually increase its charge due to simpe physics: it charges with 1.5A from the wall, and my nexus 10 used 1.2A of those, and adding some inefficiencies on that it would likely mean that it would just hold a charge level in the anker battery, not increase it. But as soon as the tablet ramps its current draw down the anker would suck up any left over juice. This becomes even worse of course if you charge a phone at the same time.
One little note: The battery in this is not the most awesome (also the capacity measurement is a simple voltage-based instead of counting coulumbs). While charging with ~1A from the 1A port, when I added my nexus 10 to the 2A port the charge indicator actually went from 50% to 25%. When removing the tablet the LEDs indicated 50% charge again. This is due to voltage sag which is itself due to internal resistance of the batteries. Meaning: The faster you charge the more heat will be wasted in the batteries. So to really prolong the battery life you should actually charge slowly, at least as far as the Anker is concerned.
Thanks for the review, I will probably be getting one now.
An interesting new USB charger on Indiegogo uses butane lighter fluid with a thermocouple to charge your cell phone.
I'm thinking this would be great for those overnight multi-day camping trips. It charges at a 1A rate, so it should be good enough for most Android phones.

This is a great idea. Will certainly be funding this. Thanks for this! The party in Istanbul is kinda weird though
I had good luck with a $100 solar panel this summer camping for two weeks at a time. There are nice solar panels on Ebay with built in 5V USB ports as well as the ability to charge any 12V battery (which I use for ham radio too).

they also make a basi powercell thats good for 8000mah or more that is like a bigger battery you plug into it usb for 30$ or so
Would you want to enable fast charge while you're using something like this? Or would it matter?

If you mean by mobile bank "is it a battery"? No, it's a generator. It doesn't hold a charge, it only creates electricity from butane directly.
Capacity from the Q&A section:
Q- How many refills can you get from a can of fuel?
A- A regular can of butane is 300ml. And the fuel tank inside the device is ~60ml. That means, you can refill The Smart Charger 5 times with a can of fuel.
Looking at the trend line for this project, I doubt it will make its target and won't be produced. Neat idea though.

Its a solar power charger, of course it will only charge in sunlight, but it should contain a battery which will hold a charge for additional night time charging.

That's a very cool project, I hope it succeeds. For now, there's the BioLite camp stove. It's a bit bulky, but runs on wood. I'm currently trying to justify the bulkiness for backpacking... A butane charger would be much nicer, though!

Hi guys,
I have a very bad battery life on my OPO (max 2-2:30 SOT), and I need a good car charger while I use GPS, and a power bank.
I would appreciate it if you can give me links on ebay.
BTW, is it safe for the phone to use these chargers?
Thank you!

The charging rate with screen on is limited. The stock amperage limit with screen on is 1A. I get notably better current flow on CyanideL (likely a kernel thing).

Amazon doesn't ship to my country.
Do you have a link on Ebay or Aliexpress?
Regarding the power bank, do you recommend the One plus bank than the Xiaomi power bank 10,400mah?
Thanks again!
The OPO bank is a safe choice, since it's from them and likely tested by most forum members to be accurate.
Xiaomi, especially on Aliexpress and eBay, has a LOT of fakes, obviously cashing in on the brand and shortages. Make sure it has branding inside the USB ports if you are buying Mi. The 16000 is a less faked model, since it's newer and uses a different form factor. The advantage it has over the OPO bank is it supports 2A on both ports, and gives max current of 2.1A / 1A total when two devices are plugged in.
With the OPO, it gives 1A / 1A when two devices are plugged in, and 2A maximum on a single device. If you do not charge multiple devices often, the OPO is cheaper and less likely to be fake.

Hi there,
Thanks for your reply.
I can buy only from Ebay or Aliexpress, because One plus doesn't ship to my country.
The One bank is about 30USD over there, and the Xiaomi is half price, that is why I thought of it, but it is hard to know if either of them is fake.
Do you have an idea about a decent car charger?

Anything that is a 2.1A car charger should do it. If you are unsure of the quality, you could always get a charge doctor for $2 USD on Aliexpress, which will tell you if the port is good or not. For example, if the reading shows 0.5A output or less, the product is garbage and you should demand a refund. I suggest getting one if you buy chargers and power banks on eBay, since it can validate how good (or bad) your product will be.
If you still want the Mi bank, two things to look for are the small Mi logo inside the USB output ports, and test to see if you can still charge your device while the power bank itself is charging (pass through charging). These two features are hard to fake. Do not rely on serial number stickers, since counterfeiters will sometimes put a fake power bank inside a real box that they salvaged from someone else.

Yes they are. It's a simple circuit with a high resistance to measure current and an LED readout. A few forum users have them to do readouts, and they can detect bad wall adapters and cables too. They are accurate +/- 50mA, which is good enough, considering a bad output will be off by 500-1500mA.
As for safety, eBay is always a gamble. I would go for a seller with a return policy, so if your charge doctor test shows the product is defective or fake, you can send it back.

If it is less than 2.1a, is it unsafe for the phone, or will just charge slowly the phone?

2.1A is the maximum output, which is more likely to be closer to 1.7A because of cheap parts. What you are concerned with is the minimum rate. It should charge your phone at a minimum of 0.7A, unless your charging cable is bad. You can find out which charging cable is better by connecting them one at a time to the charge doctor connected to the wall wart and picking the cable that gives a higher current output. This is how I sort out all the charging cables I get from eBay, and a good number of them have bad pin shorts that lead to them being capped at 0.5A.

Thanks for all the info.!
So I'm in my junior year of electrical engineering and seeing the incredible things done with smartphones is something I really would like to be a part of one day. I wanted to discuss, considering the limits of current technology, if it would be possible to create a safe Dash Charging power bank for this device? For those who don't know how dash charging works I'll post a few links and my understanding of how it works and if I'm wrong at any point feel free to correct me.
Dash Charging - The Technology
The way dash charging works, as I understand it, is that the USB-C cable wires are made wider in diameter to accommodate a larger amount of current being passed through to the battery. The charger plugged into the wall takes on the burden of the extra voltage pushing the current through the wire and keeping it away from the phone's internal battery (which is brilliant). That means that the charger takes on the extra heat which isn't a problem because passive components are often more tolerant of heat than batteries are.
Links:
http://www.phonearena.com/news/How-it-works-Dash-Charge-fast-charging-on-the-OnePlus-3_id82646
http://www.trustedreviews.com/opinions/what-is-dash-charge-oneplus-3
The Issues
A dash power bank could be charged up exactly like the phone; with the dash charger it could fill extremely fast. However, using the battery pack to charge the phone means that the internal Li-Ion batteries of that charger will be taking on the extra heat from within the case which could:
a) shorten the power bank's life span
b) Possibly lead to unsafe power banks if it got too hot
I also see there being limitations with the power bank's ability to maintain a full speed charge similar to wall charging along with what types of batteries would be needed to provide the power output similar to the dash charger.
The Solutions
So in my limited knowledge I think that the biggest enemy here is heat generated in the power bank. I feel like the rest could be overcome with a fairly large bank of 18650 batteries. It is possible to have a passive cooling system built into the power bank for heat dissipation but that might make the battery bank difficult for users to hold on their Pokemon Go outings. Also, reducing Dash Charging specifications just a little, decreasing the speed at which it could charge the device, would alleviate some of the concern. So while you might not get 60% in 30 minutes from the wall, perhaps aiming for 45-50% charge in that amount of time would increase the power bank lifespan and total amount of charges.
What do you all think? I'll readily admit I don't understand completely how current battery bank internals work to limit over-current and over-voltage scenarios as I've never taken one apart. If anyone wants to educate me and say whether they think Dash Charging is possible I'd love to hear about it. This is the kind of stuff I imagine the OnePlus engineers are sitting around working on every week.
i think that would be too expensive to make for consumers, u figure if a dash charge block is almost $30.00 this thing would be well over $500.00 which would be too much for a regular consumer to purchase just to have a portable charger, maybe in about the 3rd or 4th generation of this technology we could see one in about 5 years, they would rather make a ton of 30.00 purchases and have you buy their charge block opposed to very little purchases of about 500.00 for power bank
It's actually already there in the market,
named "OPPO VOOC Powerbank"
attached is mine, working fine with OP3 Dash,
Price is around $45-50 - 6000mAH
Charging rate is 3,5A
and it DOES charge my device up to 60-70% in 30 Minutes
it heat up though, especially near the plug (USB C end)
this is why i use the metal based USB C adapter, so it release the heat faster

I'm going to build power bank using Dash Charge car charger. The power banks higher voltage (12V if using car charger) means less current for individual cell while charging. I have bought battery holder case 10 x 1,5V for AA batteries. http://r.ebay.com/vpShFJ (I already have plenty of Eneloop AA batteries for other accessories.) Each Eneloop has at least 1,5Ah (1500mAh) capacity while retaining voltage at or over 1,2V. http://lygte-info.dk/review/batteries2012/CommonAAcomparator.php I'm going to attach 12V socket to the battery holder case so I can use my car charger both in car as well while at camping.
Battery bank consisting of 10 x AA Eneloop has a total capacity of: 12V*1,5Ah=18Wh.
Dash chargers input is rated at 12V/2.5A so each individual Eneloop would have about 250mAh discharge rate.
My old Galaxy Note 3 had 3,8V 3200mAh battery and the capasity was ~12,2Wh. I don't know the nominal voltage of OP's battery but I would estimate it's about the same as Samsung's so the capacity should be lower than in Note 3. Maybe around: 3,8V*3000mAh=11,4Wh.
10x Eneloop batteries has a capacity to give energy for charging OP3 from 0% TO 100% at least. (18Wh/11,4Wh = ~1,6)
I think in India it's not available

We're going to need a hardware XDA for people like you. I never would have thought to string together Eneloops to make an external charger since most of your power banks contain 18650 with overcharge protection and stuff built in. The wall dash charger is spec'ed to run 5V at 4A and the car charger loses half an amp to land in at 3.5A max. Car charger voltage varies between 3.4~5V from what I can tell probably based on the car's cigarette lighter specs.
What kind of case are you using with the eneloops and what are you using for overcurrent/voltage protection?

You are right, the car charger uses lower current and is probably a bit slower. When I receive my car charger I will do some testing and will report back.
The voltage variation is needed on all chargers. When the battery is almost full the charging voltage drops.

I have ordered a case like this: http://r.ebay.com/vpShFJ
The car charger has been designed to be used as it is. The charger itself does not require additional overcurrent protection but in case of a short circuit a 5A fuse is needed to protect the wiring and Eneloops. Overvoltage is not a problem as the maximum voltage with Eneloops is going to be under 15V.

Yes it is. I've posted it in another thread as eell. Just check through my post history.
This is pure logical, since Oneplus is just a subsidiary company of OPPO, so they surely can share few technologies between each other, and VOOC/DASH is one of it,
Just make sure your usb c adapter quality is good when you decide to use it with VOOC charger.
