AC Adapter 1 Amp or 500 mAmp

[ChTidio]

I have a generic AC adapter (from a different phone) that I want to use as an extra - one at home one at the office. The output is 5 V, as expected, but the output current is 500 mA, instead on 1 A (1000 mA) on the one that came with the phone.

Would I harm the phone if I used the 500 mA AC adapter with it?

It shouldn't hurt anything but will take twice as long to charge.

If you buy the micro-usb travel charger(the one without the USB slot that plugs directly into the wall and folds up when finished) directly from Sprint for the EVO Shift it only has an 850mah output. So, even the travel charger directly from Sprint isn't rated the same as the HTC charger that comes with the phone. It just takes longer to charge if the output is lower.

I use a charger from my old Sanyo SCP-3810 that is rated 800mah and it works great.

^Good stuff!

I charge my phones off of my laptop - 5V, 500mA - no worries.

ok so i have a question. I have tons of spare use/mini usb cables lieing around and read a thread on here about some one using a mini to micro adapter and just get a usb car charger. I concern is the hole 5v/1a thing. how do I find out if the cables will put out the juice i need, or does it have nothing to do with the cable just the plug in part and source?

Aside from the odd chance of a cheap cable going bad, you don't care about that, just that it fits the phone.

In a car charger you care about a clean 5 volts, so you want to avoid the cheapest adapters there.

I charg with a .25a charger on the overnight because it has a long cord I can use it in bed while charging. Works just fine. In the car I would definitely go with something at 1a since streaming media and nav suck battery at a good clip. As EarlyMon states, don't go with the cheapest one you find.

query: If a phone comes with, say, a 700 mah charger, will using a 1 amp charger damage the phone?

No, the 700 ma, 1A, etc. are max output ratings. They just tell you what the charger is capable of, not what it will "push" into your phone.

 

[EarlyMon]

Foremost, check the phone specs if possible.

It shouldn't, the charging circuit ought not draw more than it can handle.

Under the battery should be what it's rated. My Shift is upstairs, but my Epic is actually rated at 1500ma. The mfg's are either cheap or conservative.
