Hi guys, i only have my ipad 2 charger, because my one xl charger is missing, is it safe to charge my xl with ipad 2 charger?? is higher amp will damaged my battery?
Thanks guys :laugh:
Use same amps and voltage outputs. Safeguards your device.

Is it the 2 amp charger?

Ours is a 5 amp,isn't it?

It's 5 volt.

I meant volt. Sorry

If the amperage is more it won't make a difference, all usb chargers should be 5v. If the amperage is less than that of the HTC charger it may not charge or register a charge but actually discharge (fatal to a lipoly battery if it drops too low). The amperage is the maximum load the device can safely output the 5v. If the charger was rated at only 0.5amp then the voltage would drop (it might only output 2v or spike randomly) if the phone tried to draw more, if the charger used shoddy conponants then it may overheat and set on fire.
A higher amp rating is fine, infact you may get a cleaner output. For example your wall outlet might be rated at 13amp but you can plug in a 1amp shaver or a 13amp kettle - it makes no difference.

Hello everyone,
I can't find my wall charger. I had to charge my phone so I used a wall charger for my tablet. The charger's output is 5v-2amp. The oem charger's output is 5v-1amp.
My question is will my temporary charger have any negative effects on my phone since it charges 1amp higher than the oem charger?
It shouldn't. My friend used his iPad charger for his iPhone long term. It didn't have any negative effects on it.
Edit: all it did was make it charge faster. An it did have a different voltage and amperage output than his iPhone charger..

Depending on the internal circuit of HOX, it may or may not harm your phone. iDevices are pretty good at operating with other iDevice accessory and may have circuits built to prevent damage. Check if it gets very hot - if true, don't use it.

USB is a universal plug designed for up to 2 amp at 5v... Typically the phone (or device) will only draw as much as it's a capable of handling... But I concur with the above post, if you think is getting to hot just charging, probably stop...

I agree about the charging faster and this reminded me of an article that I had read recently. Check this out:

I use my touch pad charger to charge my one x. It charges a lot faster. No negative effects.

Amazon Kindle chargers work as well as OE HTC chargers, and the cable is longer. I bought a couple of the $.01 chargers from Amazon for my Inspire 4G, and while they worked, the official HTC ones charged faster. When I got the HOX, the cheap chargers would charge for a bit, but then stop. So I picked up an extra Kindle charger and it works great!

+1, also use my kindle charger for my HOX, much longer than the stock HTC cable and charges just as fast.
I charge my Kindle with my HTC One X charger and I charge my HTC One X with my Kindle charger.
My car dock is attached to a 2.1A charger, no extra heat and no other obvious negative affects.
This question has been asked before but no one can answer it odd.
Nexus 7 charger is two amps. Stock s3 charger is one amp.
Can I charge my s3 without damaging it using the other charger. People say it charges faster. Some people say it doesn't matter because the kernel will limit it.
Whats the real deal?

I am pretty sure it will use only what it needs. Atleast thats what i been taught at radioshack

There are a lot of variables as to what the maximum charge current will be. I've never seen it go over .8 amp. So if you use a 1 amp, or a 20 amp charger, it will be .8 amp. MAX. Usually less.
Use whatever you have handy that is 5 volts.
I actually use an old 5 volt .6 amp charger for overnight charging. A bit slow, but I don't care.
I have a home grown charger on my motorcycle that can go well over 1 amp, but the phone only has ever gone to about .8 amp. For a long time I had that charger set to 5.5 volts, and the current was up a bit closer to 1 amp. But the heat worried me and I bumped it back down to 5 volts.
Have been charging my s3 on the new iPad charger, and 2amp chargers bought from amazon without any issues.

I'm using a RCA dual usb charger one usb plug is 1 amp and the other is 2.1amp both charge fine but I don't notice the 2.1amp charging any faster. I so kinda point less to use in my eyes

You realize you're using a 10v charger on a 5v device right? That can toast your battery over time, a short time too depending on if you leave it plugged into it over night, etc..
I can't remember where I read this on Motorola's website, but I seem to recall
something about charging the Moto G using USB chargers under 1.5A.
All of my chargers are 2.0A or higher. (all were original chargers from
my four Samsung Galaxy Note 2 and 3 phones, as well as tablets)
is it really unsafe to charge the Moto G with 2.0A USB chargers?
You are fine to use any amperage you want. The charging chip determines the amperage it pulls. The only danger to electronics is the wrong voltage, not amperage.

that's what I figured, but why does Motorola feel the need to
say "up to 1.5A"??? (in fact, I don't think I have ever seen
1.5A chargers... they are usually 0.5, 0.7, 1.0A, or 2.0A.
Because they are letting you know the maximum rate at which it can charge. It's not a warning that you can cause damage, just a notice that is the most the charging chip will pull.

I'm using a 2.0A charger for about 2 month now without any problems. :good:

It is the maximum capacity the charger can supply. So if the device only needs 1.5 A and the regulator circuit is not faulty, it will only provide 1.5 ampers.
What's the side effect of using 2A output powerbank on the cellphone ?
From my experience, the output of cellphone adaptor usually between 500mAh-1Ah. Well, except phone with bigger screen (which i don't have).
What i notice is, the back of the phone are usually hotter compare if i charge my phone using phone adaptor or via usb.
I am kinda worry with this excess heat. Heat is not good for electric components.
It will shorten the lifetime of the battery

Seriously ?
Yes, if the phone is not designed for 2A

What about a phone that's designed for 750mAh and it's being charge with 1.2A powerbank ? Since the common minimum powerbank output are 1.2A.
Even that would be harmful there are 500mA powerbanks available which would be ok

I see. Thank you.
What about the opposite. 1.5A capable cellphone that's being charge with 750mAh charger ?
I think it would be fine. Just the time it needs to charge the phone is longer. What do you think ?
That would be perfectly ok, you're right it just takes longer to charhe

it does not work with my touchpad (HP). If i not charge with 2A output is no charge
Im curious if I can use the extraordinarily large USB cable from the nexus 7 coupled with my m8s wall plug and get the same charging speeds from the higher amp charging wall plug? I only ask because HTC makes some pretty short cables and hinders my internet browsing at night abilities :good:

Length of dc wire will lead to voltage drop. Lower voltage means the unit will draw more amps to get the same wattage of power. If anyone needs a longer cable make sure it's not cheap and that it uses a heavier gauge USB cable. Unless you are fan of heat in both your charger and phone.

Yes, but we are talking a foot or two at most here; the voltage drop would be inconsequential.

Depends. I have seen some pretty crazy six and ten foot cables lol. The user then wonders why the slow charge.
