For review today, I have an Aukey PB-Y14 Powerbank rated at 20000 mAh. Overall I really like this Powerbank. It is very versatile in so much that it can be charged with a lightning plug, USB-C, or Micro-USB. For outputs it has 3 USB-B plugs and the lone USB-C is also an output. Charging speeds are slow being that this powerbank doesn’t support Quallcom’s QuickCharge in any way. Having said that it still does a great job. I already owned another Aukey powerbank (Model PB-T10) which does support QuickCharge 3.0 and it is very fast. Once depleted, the PB-Y14 takes quite a while to charge, but to be fair it is a pretty large battery. It has only needed to be charged once since I’ve received it, and so far it has charged my Note 9 twice and my Chromebook once, battery life as indicated by the row of LED’s on the side shows 50%, so it seems to be holding its own quite well and I like the battery display on this unit much better than that of the PB-T10 which shows you a colored led and you must remember which color coincides with what power range. In summary the PB-Y14 is a very good power bank but would not be my only choice. I like it quite a lot, but I also like my PB-T10 an equal amount. I will continue to keep the PB-T10 in my daily carry bag and perhaps keep the PB-Y14 around home for emergency power in case of outage or possibly to be a mobile power supply for a small computer such as a raspberry pi. My recommendation would be to weigh out your needs as these are both high quality and very affordable. If you must have fast charging, go for a different model such as Aukey’s PB-T10. If you have a need to charge more than 2 devices (the PB-T10 only has 2 outputs) or greater versatility for charging your powerbank (the PB-T10 only has lightning and micro-usb inputs) go for a PB-Y14.
Thank you for posting

Powerbanks are much needed for me because i use so many devices daily and as you know the battery is never big enough on any of your devices so having a extra 10000mAh in the palm of your hand is much needed. This EasyAcc 2nd Gen powerbank is very small for its output and having 2 USB ports at 2.4A you can charge 2 devices at same time plus there is also a very hand LED flashlight between the 2 USB ports that you will see is a great feature. few specs are Input: DC 5V 2A so unit will charge fast when needed and Output: DC 5V 2.4A (max) and at 7.97 oz your able to comfortably carry powerbank in your pocket. Remaining power is very easily recognized by the 4 white LED lights on top of powerbank and read as follows: 1 light=25% 2=26% to 50% 3=51% to 75% and 4 LED's lit is 76% to 100% so powerbank is very user friendly from charging powerbank itself to charging your devices. There are many powerbanks out therebut this powerbank is smallest I have ever used and very feature packed. My video review will help show units features in real time and I hope shows just how good this unit is. http://www.amazon.com/gp/product/B00XTXY0JW?ref_=cm_rdp_product

Here is a great read on power banks 101...

Power bank as gadgets are very popular these days because they can be very useful for smartphones or similar devices.
So today I will try to introduce to you EasyAcc Monster which actually have huge capacity 26000mAh.
Talking about the build quality and design it is more or less the same as any other power bank. The case is made of plastic
and very interesting information is definitely weight (454g). So I think the capacity could be real.
EasyAcc Monster has four Smart USB ports and because of that you can charge four different devices at the same time with
maximum output 5V 4.8A depending on the device. So you can charge the smartphone in same way like you do that with your DC charger.
For charging itself it has two micro USB ports. I think this is a good idea because you can charge the power bank
much faster than usual and you don't need to wait too much. You can charge it with maximum input DC 5V 4A.
So it is completely up to because you can charge it with one charger or 2.
Lately I saw several other Power banks and they all have built in LED flashlight. Obviously this is must have
equipment and because of that EasyAcc Monster has also LED flashlight which actually is very strong and can be useful in some situations.
So all of you are wondering is the capacity 26000mAh real or fake, because many of you saw batteries with
fake capacity and this is nothing new today. So in my test with calculations these power bank has approximately
20000mAh capacity and for me this is a good score because there are no large deviations.
Anyway if you need more information about EasyAcc Monster power bank you could visit thier official website.
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.

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?

So... can you tell me if a normal VOOC charger block charge the OP3 as fast as the original dash charger in package?
I saw it is the same current rate, but the technology, is it interchangeable?
Just wait oneplus is planning to release a dash charge powerbank with 10000mAh so stay connected no need to buy oppo 6kmAh one

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.
i'm back with a few more chargers to test, this time from baseus which i have to admit i've never tried before. they sent me the 45w charger/10000mah power bank as well as their 120w 3 port wall charger. the first thing that jumped out at me is the size of these things. even though they employ GaN they are larger than I'm used to. it is somewhat understandable on the 45w charger as it also doubles as a power bank, but i was really surprised at how big the 120w charger was. that said, performance on both of them were great and they feel really dense, so they don't appear to be wasting any space.
the 45w charger was the one i was intrigued the most by because of its versatility as a wall charger and a portable power bank. you can plug it in to use as a charger or charge the 10000mah battery, and both usb c ports can be used to charge the battery as well. baseus claims 45w max output on ac power or 30w max on portable power through either of the type c ports individually, or when used together 30w+15w or 15w+30w on ac power and 18w+18w on portable power. i tested it using my pixel 5 and a completely dead samsung chromebook plus and noticed consistently that the top port had a slightly lower voltage than the bottom, despite both being rated for the same. neither port delivered a full 45w on my testing. with the chromebook and the charger plugged in the top port maxed out at 2.35a/14.6v, with the bottom port delivering 2.35a/15v. plugging in a second device dropped the charging speed to 1.85a/8.7v and 1.9a8.8v for top/bottom. in powerbank mode the top/bottom gave 2.2a/11.7v and 2.2a/11.9v individually, 1.9a/8.8v and 1.9a/9v with a second device plugged in.
the 120w charger offers 3 ports, 2 usb c and 1 usb a. theoretical power output gets a bit complicated; the usb c ports can put out up to 100w individually, or 60w+60w when used together. either usb c port used with the a port will put out a max of 87w with the a port delivering 30w, and if you use all 3 together the top c port will put out 60w, with the bottom c and the a port putting out 30w each. in my testing i was able to maintain charging speeds of 1.85a/19.2v on the top port regardless of what the other ports were doing. on the bottom port the speed was similar, but dropped to 2.2a/12v once i had all 3 ports in use.
as i mentioned earlier these chargers are quite large and heavy. the 120w is noticeably heavier and larger than a 90w 3 port charger i recently tried out. obviously it delivers 33% more power and there is a lot to be said for that, but i think for most users this would be more of a wall solution versus a travel charger. the 45w charger is much larger than a few other 60w chargers i have, but again this baseus charger offers a fairly unique advantage of both plugging in and using portable power. while these chargers dont fall into the ultra-packable categories, they both offer value in the extras they can deliver. right now the 120w charger is available on amazon for $44.99 after clipping the on-page coupon, and the 45w for $32.99 after clipped coupon, and if you buy both it gives you an extra $5 off of each. as always these are not affiliate links; im not affiliated with any of these companies and dont receive any compensation for these reviews.

I'm using my Xiaomi 55W wireless charger with the 120W supply that came with my Mi 10 Ultra. Works a treat.
So what actually is the FASTEST charger that can be safely used with the P5 apart from the supplied Google charger that comes with the P5 and the Google Pixel Stand ?
If a non UK forum member replies, remember I'm in the UK, so ideally I'd like one that I can source in the UK, but I'd still be interested in what others are using.

As far as I'm aware, using a charger with more power than the supplied charger makes no difference. The device decides how it will draw power.
These high wattage chargers are mainly for laptops.
I bought this 45W charger few days ago, but with one usb-c and one usb-a port. First I bought variant with 2 usb-c ports, but it didn't work well, it only charged from the wall, but when tried to charge from battery, phone started to charge power bank instead of the power bank charging phone, so I returned it and got the variant with one usb-c port and with one usb-a port, because they didn't have option with two usb-c ports anymore. I actually love this charger, because you can use it for both, as wall charger and as power bank and that's awesome for traveling and it also have PD. But I don't think it's really 10000mAh power bank. I tried to charge my phone from power bank, the power bank was fully charged, and my Pixel 5 was 50% charged. I left it overnight and it charged my phone to 100%, but power bank has only 25% battery left (1 light on out of 4). I don't think 10000mAh power bank should last only half of a charge. I was thinking about ordering other charger and power bank, but I couldn't find any charger and power bank in one device other than that specific device from Baseus.
First off: love this phone. Already selling my S21 Ultra. However, I found an issue that seems specific to the Pixel 6 Pro.
I have a ton of wireless chargers but most don't seem to push enough juice to even charge this phone. Which is weird, because they are capable of pushing at least 9W but in most cases, they don't even push 5W to the phone, even when the battery is <25%.
I have one fancy charger (moshi Sette Q) which can push 15W per coil--there I can max out at the Pixel's rated 12W if the phone is cool, but only until the battery hits 90 deg F. Once it exceeds that, the charging rate drops down to 7.5W or lower, and the predicted time to full charge more than doubles. Coincidentally it seems to hit that 90 degrees within mere minutes of starting the wireless charge. I'm measuring battery temp (not power) using AccuBattery, and power using various USB meters.
The same chargers, power bricks, cables push their max wattage to the S21 Ultra even if the Ultra is >50% charge. And just for kicks I tried my girl's iPhone 13 mini and it instantly hit its max charging power w/o MagSafe (10W, from what I can see). In other words, there's no specific evidence that there's any issue with my power bricks, cables, or wireless chargers. All are reputably branded and genuine parts and if they work with both the S21 Ultra and the iPhone 13 mini then you can probably rest assured they are not the problem.
So, it seems like the Pixel 6 Pro is doing some severe thermal throttling when wireless charging, and the upshot is that you barely ever get the full 12W Qi charging capability of the phone, and most of the time you end up charging at <7.5W.
Anyone else seeing this? If you're charging wirelessly, how's the experience? Does your battery hit 90 F in no time at all? Does it start to reduce Qi charging current once it hits ~90F?
If other folks are having a fine time wireless charging this phone, and you're getting that full 12W on the reg, I guess it's possible that I have a bum phone. Let me know what charger(s) you're using. But if you haven't noticed a problem yet, you might want to pay closer attention to your charging speeds to see if you're seeing the same thermal throttling.
If it's not just a bum phone, then this seems like a major issue. Big enough to force Google to delay the launch of their next-gen wireless charger, the new Pixel Stand.
I'm seeing the same. New Anker magsafe style charger is 3-4 watts... iOttie car vent gets it to 9-10...
Yes, same problem. I wonder if that's why we haven't seen the Pixel stand.
I'm using the original Pixel Stand and it seems to be charging at about 14W which is the max it can deliver.
I haven't noticed it getting very warm when charging but then I have been asleep
I have noticed a couple of times, lifting the phone off the charger in the morning, it was slightly warm. AccuBattery said it had been fully charged hours before that.
The phone is in a Spigen Rugged Armour case and I just leave it in it to charge.
how do you check the speed its charging at? Ill check mine overnight and see. I bought this one...

I'm using one of THESE and also have AccuBattery Pro.
One thing I found with AcuuBattery is it seems to assume the charging voltage is always 5V
So when I am charging it shows the current as 2.3A x 5V = 12.5W
Whereas the actual charge on the voltmeter shows 1.4A x 9V = 12.5W
Interesting. I just set my phone down at night on a fly-by-night brand qi pad I bought several years ago, and by morning the phone is charged full and ready to go. Don't know, or care, how fast it charges as long as its full by morning. The few times I've had to grab the phone after charging for a while, it hasn't seemed at all warm.
But I'm running on google-free nice clean AOSP. Might be that some of that google spyware is sucking up power faster than you can supply it?

The way I've been doing it is via a USB C power meter which is just in line between the wall wart and the wireless charger.
I also have a USBC cable that has a built-in power meter and I get similar results. Another thing you can do is just put the phone on charger you have, then go into settings and battery and just monitor the time estimate for charging. Do you ever see it advertise upwards of 3 hours of charging time or otherwise jump from something reasonable like 2 hours up to 4 hours?
It seems like there's two main problems. Number one that the wireless charging coils are extremely narrow compared to S21 Ultra. So the sweet spot is super small and difficult to find. Number two. Once the phone hits 90° f, then it is throttling the charging speed. And honestly, I don't know if that's a cooling problem or if that's just an overly conservative algorithm. Either way it's kind of ****ed up to advertise 12W wireless charging and then have this type of experience.
I've been using the app Inware to see the live amperage, wattage, and voltage.

Thanks for the tip. I didn't know about that one. I think the problem here is probably related to the overall charging limitations that the phone has. If you look at the other threads in this form, you can see quite a few that are related to slow charging speeds even when using the wall wart. But still this is extremely disingenuous from Google and straight up inaccurate advertising when it comes to charging speeds.
For those of you who have the old Pixel stand charger, IT WORKS !!!
All I want is a full charge by AM, and it usually gets a lil boost charge when I drive my sprinter.
About to look for a new wireless charger, but now using the 30 watt Google plug and cable and phone charges up faster than any I have owned previously, nearly all galaxies but the 6 Pro is noticably better, wired.
