Are there any recommended AA or crank chargers? It should have enough current and be able to let the phone know that it's a high current charger.
Thanks

I am going to buy a car charger for my new HOX, but it only has one 2.1A usb output. I know the charging current of the HOX wall charger is 1A, but I think 2.1A should work fine or even charge faster. But my concern is if the larger current would hurt my battery or shorten its lifetime.
Some ppl said the phone itself would take 1A current anyway due to some kind of threshold control inside, but I am not sure about it. So pls let me know if you know the truth. Appreciate it!
ps. I sent an email about this problem to HTC customer care 2 days ago but still no response yet. I will post the official answer when I get their answer.
UPDATE: Here is the official response from HTC about charging current, it seems that HOX does not intelligently control its charging current:
Dear yydnl,
Thanks for getting back to me, yydnl. The One X was designed with the intention of only using 5V 1A chargers. Anything more will cause damage to the phone over time. The phone was not designed to alter the current coming into the phone through the charger. I recommend that you only use the supplied HTC charger with your device.
Yeah I'd like to know. I never opened the oem charger and am currently using my bb playbook charger which shoots out 1.8A. I'm hoping the answer is no damage with a faster charge.
Yep, it'll work fine. Chargers don't "push" the charge, the phone pulls it. If the phone is only designed to charge at 1000ma, then it will only pull that current. So you could use a 10 amp charger and it will be fine, only difference is that with that high a capacity, you'll be able to charge 10 phones at the full charging rate. Changing the voltage, that's a different story.

There is no problem of the voltage of the car charger because that is 5V as the oem charger, but do you know if HOX is designed to intelligently pull the proper amount of current? or will it take any current fed to it?

All Li-ion batteries have intelligent charging circuits. Otherwise, it will simply explode.
I won't worry about 2.1A at all. The problem is other way around, i.e. whether or not the phone will take more than 500ma from your 2.1A charger. It depends on how your charger is wired. If the phone only detects a generic USB connection, it will only charge max 500ma. It requires special wiring from the USB port to allow phone to switch to AC charging mode to draw more current. Unfortunately, there is no way to tell until you have the charger and try it out. One thing for sure, those chargers designed for iPhone/iPad typically won't be recorgnzied by other phones as AC chargers.

Gotcha, the car charger I am going to buy is for iphone, but it also claims to be able to charge phones of htc, sony etc. So I guess it is possible to have the ac charging detection.

My money is on that it won't be recognized as AC charger. iPhone has special requirement on data PIN wiring that is not compatible with other phone. Yes, you can charge other phones but probably not at anything over 500ma.
Pls see my updates, it seems that 2.1A charger is not safe.
I was wondering if this car charger was safe to use on my Blaze (a Scosche 2 USB port charger). The info on it says:
input: 12-24vdc, 1.5a
output: 5v, 2a RoHS
(made in chine etc).
I have heard conflicting opinions about the use of third party devices for charging. Most notably, the T-mobile chat reps say they
"do not recommend" using them, but the ones on their very own website are mostly third party ones (at least they appear to be to me).
I have also heard that as long is the plug fits on the phone correctly it is safe.
Could someone clear this up for me? Will the scosch work and be safe? Or, could you recommend one that is safe to use on my blaze?
Thank you so much!
That will work perfectly fine. 5v and any amperage will be acceptable. The stock charger is good for 1A, so charging on a lower amperage charger will only increase the charging time.
I believe the Blaze will only pull around 1A max when charging, although a kernel tweak should be able to unlock fast charging in the future, if it already hasn't.

Thank you for your reply. Yes, it was the 2A output that concerned me after doing some reading. Can anyone confirm what the max amperage the Blaze will allow? I just want to be sure that 2A will not be a problem.
NOTE: It charged my old Iphone 3GS fine.
The charger does not "push" 2A to the phone, the phone draws as many amps from the charger as it can provide. The 2A rating just means that it will be able to quickly charge a device that needs that amount of power, like an iPad. Most phones will draw between 500ma (.5A) and 1A.

its kinda like bandwidth... the charger doesnt push 2A, the charger's bottleneck is 2A. If the phone charges at 1A, only 1A will be going through the charger regardless of the charger's 2A limitation.
At least that's how i think it is... its been a long time since my Electrical Engineering portion of Intro to Industrial Maintenance in highschool....
Hello everyone,
So I have been trying to find the answer to what I am wondering but to no avail. I know that when using a charger that did not come with the phone it needs to have to same voltage to not hurt the battery, but I am unsure of the amps. I know for normal powering of things the charger needs to supply the same amount of amps or higher so that the item can pull enough power from the charger. However, phones do not need a certain amps to be powered by the charger. So I want to know if I can use any changer that has 5 volts, but varying amps. This is because I read that if you use a charger with lower amps it is better for the battery as it is not charging as fast increasing the life span of the battery, is this true?
Example: I have a LG G2 which uses a charger with 5V and 1.8A , but I want to use my nexus wireless charger that is 5V and 1.2A
Thanks for any assistance!
Maybe this is just needless concern on my part, but when I plug my phone into the charger at night I don't like the idea that it defaults to fast charge. I'm skeptical about fast charge because I just figure it can't be good for the battery's longevity to be subjected to such increased current on a daily basis. Since I can't find a way to turn it off with the stock charger, I've been using my old HTC one charger. My only issue with that is that the HTC charger is rated for 1A, where the GS6 stock charger is rated for 2A at 5V. I figure the extra amp is probably for the actual fast charge and that the 1A for a regular charge is probably OK since it seems to be the standard current draw, but I'd rather use the stock charger for a regular charge if it is possible.
So is anybody aware of a way to disable fast charge? Or does anybody know what the exact current rating is for a standard charge so that I could verify that the HTC charger is within spec?
easiest way is to just use any of your other micro-USB charges. only the fast enabled plugs initiate it so easy fix if you have other charges.
Will any chargers that supply higher volt / amp combinations charge faster than standard or does it need to support dash or warp charge? I don't necessarily need the warp charge but faster than my current op2 would be great.
Anyone? Does higher amperage equal faster charging or does it have to be warp charge compatible?
There's communication somewhere along the path that allows dash/warp charge to happen. A charger can supply a high enough amperage, but your phone may not be able to utilize it without communication from the charger/cable. I'm not exactly sure how/what the process is, but I know it's not as simple as using a high amperage charger.

Any USB-C power delivery charger will do a rapid charge, just not Warp.
