Hi
I really have no idea how much 0.1A is, so this might be a very dumb question, but here we go.
I know the phone is capable of 2A charging with the charger there is with it, but will it hurt the phone using more or less A? The volt is still 5V tho.
Because I have a powerbank, that is 1A and 2.1A in second USB port, so is it safe to use both? (If yes, I would of course use port 2, for faster charging).
Also, is this true for any (newer) devices? I mean, can I plug any newer device into any Amp and just enjoy faster (or slower) charging or do I need to use the Amp that was with the original charger?
Thanks in advance
The phone will regulate it, 2.1amp won't hurt it. I have a power bank that does 2.1 and use it all the time. You likely won't find a charger that will put out much more than that tho. Even for tablets with much larger batteries.
You're fine...
A stands for amps which is a measurement of current. Just FYI.

So my DHD arrives tomorrow.
After reading about battery life, I want access to as many chargers as possible.
Can you tell me: Will my existing Micro-USB Chargers (Blackberry) be compatible with the DHD? I'm not sure if each unit will require a specific voltage / wattage?
Or can I just plug & play with which ever Micro-USB charger I come across?
Thank you & sorry if it's a dumb question...
Any cable will do fine. Definitely if you're charging through a PC since I've never heard of a phone/battery that can't handle the 5V it outputs (max for USB charging). A mains charger you can never be too sure with since it may have higher current/watt output, but I've really never let this stop me except that I'd avoid using cheap Chinese knockoffs.
It depends... microUSB connected to computer will be of course good, as it is hardware limited to 0,5A. External chargers are good question, but in my experience the phone/battery usually have a charge limiter so even if the charger does allow you to use higher current, the phone doesn't have to use all the power it can get.
For example i used the Nokia AC-10E charger for my Motorola Milestone since i bough the phone, and had no problems with it. And will use it for DHD too.
The official HTC chargers have an outpur of 5V/1A, so as long as your charger has the same output you should be good.
Nokia AC-10E has 1.2A, but as i said - that is the maximum it can give to the phone, batteries/phones have a current regulators so even if you connect a charger which can give you 2A @ 5V, nothing will happen - the phone will regulate the current which is used to charge the battery.
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....
Hi!
Have 3A charger for car (like this) and i want to get maximum power and charging speed. As i know, if i use simple usb cable, phone will get only 500mA.
How to force it to use more power? Or it use it by default, without any mods?
Found this mod for HTC, and this for Nexus 7, does it will work?

I think the mod (shorting the data lines) should work, but just make sure that the charger is actually capable of delivering the right amperage.
whoa, u really wanna do that, coz the wont hold for a long time, 3A really a big current

As of my understanding you are trying to say that charging the battery at 3A would give shorter batterylife.
Would you kindly post in a way readable for humans to make your meaning clear, as your post as quoted here was a struggle to understand.
And for complying to USB standards the device is probably able to output 2A on one of the ports and 1A on the other, totalling in a amperage of 3A. Now as I took a look at the adapter and it's specifications, it seems to me that it is just a 7805 voltage regulator in an enclosure, which I honestly wouldn't trust even a little bit.

I'm not enough of a techie to confirm or deny if this would work, but I do agree with Velihukka... I got a bad feeling about this...
You do realise to get thing working properly you'd need to wire a new 12V circuit into your car's switchbox right? You don't want to be pulling an extra 3A out of a random 12V line in your car, a lot of your internal electrics are only running 10A fuses.
If you don't smoke, you could use the line powering your cigarette lighter... but then that would beg the question, why not just use a 12V USB adaptor that can output 3A and short the data terminals?
sorry 4 my english mate, im still improving it.. yup, i think that can do, but depends on you... i would rather use 2a current output charger... i hope my batttery would last longer lifetime when i used it
You should simply go for this
http://www.belkin.com/in/IWCatProductPage.process?Product_Id=735847
It will cost you around 400 bucks for 2.1 Amp socket in your local car accessories market
And then use your data cable to charge your phone...

It wont work at all for xperia z. i am an hardware tester and i am sure any mods to hack battery life or charging it fast will destroy your battery.
You cannot force more power into the battery. The phone has circuitry that regulates the charging current, which will have upper and lower limits. If that upper limit is say 2A, it doesn't matter if you plug into a 2A power supply or a 50A supply, it will still only draw 2A.

The phones circuitry charges the phone by 500mAh by unnamed or unknown usb cable. when you plug it to a sony cable it will give you "fast charge" so it charges with 900-1000mAh. So yeah, there is something in the cable that makes it different from the other ones.
Try it with your sony cable and you get max amperage, and yeah no point forcing a million amps to it when the phone just takes what it needs.

Xz has battery monitor and its the thing that none can bypass. Also everytime the device heats up the amperage going in the battery gets more limited or even depleting...
Defects or flaw I'm not sure, but thats just it with Xz
Can anyone let me know the risks, if any, of using the OP7 pro warp charger with other devices? I live in the UK if the voltage in matters.
I wanted to have one charger to charge my OP7pro, Sabatt e12 earphones and Nintendo Switch (undocked).
Anything I should think of? I don't know anything about voltages or fast charging. The headphones say to use a charger that is 5v/1a or "risk damaging".
Can anyone advise?
Thanks
Warp charge is 5v/6a, but whatever device you are charging should limit the voltage and amps. But ultimately yes you could damage your earphones.
It depends. Like Konfuzion has said, every device should have overvoltage protection or something, even earbuds. But it will be better (more safe) to use regular 5V/1A charger instead your Warp charger.
If your device use 5V as a power source, there shouldn't be any problem to use the Warp Charger. I've already used it to charge a Nintendo 2DS and Bluetooth devices and it charges normally, because is the device who control the power consumption (and therefore, the current)
Thanks. I figured because the instructions of the earbuds were specific that it might be a bigger risk.
Thanks. Appreciate the replies. Can I get any cables that would limit the charge? I ask because it would be easier to carry two cables and one plug than 2 plugs. Sorry if that is a stupid question. I know nothing about voltages and fast charging...which should be obvious by now ?

The old dash chargers I believe had some technology that negotiated with the phone before it put out the full amps, I'm pretty sure the warp chargers/cables have that too. When you plug your phone in, you will notice it doesn't warp charge immediately, it charges normally for a second then warp charges, so any device plugged in that can't negotiate with the charger should cap out at 2a,which is where the device your charging's protection comes in. You should be fine
Edit: be careful with your switch though, they are known to brick with 3rd party charges (google/youtube that) but it might have just been crappy 3rd party chargers, I don't have a switch to test

Actually, no. If you use a crappy cable, you could get (at least) the cable on fire (It won't happen, but technically is posible if you made your own cable with a very very thin conductor).
As I said before, is the device who limit the current at charging. In the case of the dash/warp charger, the cable has "a little extra" that allow the high current, and that is why you can't use any cable to get the dash/warp experience (if you want more info, read https://www.reddit.com/r/oneplus/comments/928iqn/whats_the_difference_between_dash_charge_cables/ )
