High current car charger

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.

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.

Will it be safe to use a 2A charger for the Galaxy Nexus?

I just picked up a Nexus 7 and was wondering if I can just use that 2A charger.

No.
You can go under but not over. You risk damaging the phone's charging circuit.

Ummm. To the first response....your thinking of voltage not charging amperage. I might be wrong but I believe how much current your phone draws when charging is determined by the phone itself, not the charger. What you really want to watch for is a mismatch between the charger output voltage and phone input voltage, that's when the damage occurs

Your correct. The most it will draw at 5 volts is 1 amp. The best charger is the one that the phone comes with. If you want to learn more research ohms law and resistance balancing. Something like thevenin an mct.

Yes.
The Nexus7 charger will be just fine charging the Galaxy Nexus. It will not damage it at all. I use a Kindle Fire charger to charge my GNexus. It can provide up to 1.8 amps at a nice steady 5Volts, but it doesn't have to provide that many amps to charge the Nexus - so it doesn't.
Its the voltage, not the maximum amp capacity, that is critical, cannot be too high.
It is usually OK to use a too low amp capacity charger as well, the charging just takes longer. Usually...some chargers are designed poorly. When asked for more amps at 5V than they are designed to provide they could fail by just providing less amps than asked for at 5V, which would be fine but slow. What else could happen is that the voltage provided could start to vary. It could start to take on the characteristics of the AC current it is supposed to be converting to 5V DC. This can hurt your phone.

Moral of the story....the chargers that advertise half the charge time because they offer double the amperage are a scam/false. Just because they can provide up to that amperage doesn't matter, the device determines the actual current being pulled (I.e.--charging time)

i need of a charger. currently using a LG G2 charger thats rated 1.8a 5v .....but with a super slow cable.
is the LG charger okay to use? will it damage my m8 in the long run?

yes, i know there is a quickcharge 2.0 coming out. seeing as the cable is only $5 ...im thinking it will do for now.
thanks in advance

HTC charger outputs 5V and 1.5A. As long as output voltage is same, you can use different chargers. Ampere value just affects charging time. Higher ampere means faster charge. In long term, it can shorten your battery's life, but I don't think 0.3A can cause an observable affect

I use all sorts of chargers. They are pretty much standard now as far as micro usb goes. As said some are higher rated some are lower. I don't think there is any that will damage the phone as long as its designed for charging and is 5v.

I too use multiple chargers and cables and the only issue I've had is a double length cable that works for charging but won't allow connections to the pc
XDA app on m8 running venom

I charger capable of delivering more current will not damage your phone since the phone won't draw more current than it wants.

USB-C chargers with QC3 work fine with the Pixel2XL?

Hi,
I have 2 chargers that I used with my older phone, both are QC3 compatible, USB-C port and 1 of them can deliver 5/9/12 volts.
no matter if I use 1 of them or the charger that came with the pixel2xl I see (in Ampere app) it always charging at around 5V and 1A.
does it mean that any of them is good? is it possible to charge it even faster?
the charging speed is pretty much ok I think.

QC3 will not do anything but charge at standard speeds. This device is power delivery. QC4 will be compatible with power delivery, but good luck finding a QC4 charger.

For the heck of it, I tried the OEM charger with the Ampere app, and it was showing basically 5v at 1 amp. Tried the usb A port on my power strip that does 5v at 2.4 amps, and it read the same 5V at 1 amp. The 1 amp port on the power strip gave a reading closer to 4v at 1 amp.
Not sure what the data source is for the app because the OEM charger definitely charges quickly. I have no doubt the OEM is doing 9 volts at 2 amps. Or something definitely higher than 5v at 2.4 amps. I am assuming it is a net figure being measured somewhere not in the line from the port, since it'll also show the discharge when unplugged. So this is not the power coming into the phone.

So as far as I checked, everything is charging well.
The problem is that if you will install few other Ampere measuring programs, some will reveal that they don't have access to the sensor of the phone so the data isn't accurate.
so, we can hope it's ok. sadly I can't find anywhere a physical USB-C Ampere meter to buy for now.

Yeah, I would assume slower rate with screen on, but would it reduce from 9 volts at 2 amps from the OEM charger, to showing only 5 volts at 1 amp? Mine does seem to slow noticeably, but that'd be a big change. Unless it specifically drops the incoming power down when the screen goes on.
I think someone needs to throw down the $25 to get an in line USB C meter to just measure. I almost did yesterday, but got too busy to read the reviews of the ones available.

how to get more speed charging?

hi guys,
i have two chargers,
1. output 9.0V 1.67A or 5.0V 2.0A
2. output 5.2V 2.4A
and a usb-c cable, in the cable box i find that this cable is supporting for fast charging and support to 2.4A but when i tried it with the two chargers, and test it using 'ampere' app i got max to 1010mA with both chargers adapter ! even with this value i feel it charging my mobile quickly, and in the bottom of the lock screen i see 'charging rapidly' but i want more and why the phone is not charged depending on the values in the chargers (1.67A - 2.0A - 2.4A) and cable (2.4A)

The P2XL charger is 9V, 2A or 5V, 3A. Your amperage values are too low, which may explain why you're not charging as quickly as you should be. The solution: get a charger that equals or exceeds the stock charger ratings.

You realize slow charging is better for the long-term life of the battery, right?

Considering we often get new phones every 2-3 years, you won't see much of a degradation from rapid/fast charging.
Rather, you'll see a degradation from charging from <15% to 100% (which people do often). That will be a more significant reason someones battery will lose much off its lifespan.
I wish Android would have a built in limiter. I'm sure in the next few years, both iOS and Android will.

There's nothing I can help you guys with. All I can tell you is what ratings your charger should have, based upon the information printed on the pair of chargers I received with my device when I purchased it directly from Google. If you have a genuine Google charger and the P2XL is still not charging fast, contact Google.

i bought an original charger for my pixel 2 xl from ebay https://www.ebay.com/itm/113109823570 and after testing it with ampere app i got the same value as my old charger, i got max 1010 mA, and i don't feel that there is a fast charging, it needs to the same time to charge my mobile as my old charger !
please help

I thought that charging capped out at roughly 1000 mA when the screen is on to protect the battery from overheating/putting too much strain on it. Which could lead to degradation of the battery. That would explain why you only see 1010 mA on Ampere - because the screen is on. I don't think Ampere measures while the screen is off, so it is difficult to say what value it would be giving you.
That is my experience even using the stock charger that came with the phone.

maybe your opinion is right. my next experiment is from 0% to 100% with the old charger and with the stock charger, then i will see if there is a difference

After seeing this I checked accubattery and it also says mine normally charges between 700 - 1010 mah also. I didn't even think about fast charging, I don't have the original charger but I have other "fast chargers" that don't seem to be doing their job either.

There is one other thing that you must also have. The Pixel does NOT support Qualcomm Fast Charging. It uses Power Delivery, not Quickcharge Technology. So if you have a charger that is labeled QuickCharge or a Moto Turbo Charger you will NOT get fast charging from these units. It has to be a Power Delivery charger with a USB C port and the cable must be USB-IF certified. If you don't have all of that then you don't get a fast charge.

That makes sense then, it seems like everything gets more complicated every year.

I just purchased one of these from Amazon. Note that it supports Power Delivery 3.0. This unit quick charges my phone. The Moto Charger I have for my old Moto G5+ which is a Qualcomm charger will charge the phone but only at slow speeds.
