Hi All! Just got a Coolfire IV Plus. My issue is what kind of wall charger do I use?  I used an apple 5V-1A  charger but it gets really hot.  My rig doesn't get hot just the wall plug and that end of the USB cord.  Is this normal?  Freaking out a little and haven't been able to find much on the issue. 

Thanks, 
MK

RE: Newbie Alert
I would normally get a charger twice what I needed, you only need 1A at 5V, but your charger might be running flat out. Perhaps invest in a 2A charger to keep things cool?

However the charger should be an intelligent device that recognizes what your device needs, else you may supply twice as much current it needs.. So charger not just a dc supply

So perhaps a 2A USB Charger will run cool

Just did a search and found this;

Charging:
Micro USB DC5V/1A
The CoolFire IV Plus supports 5V/2A Fast Charging

RE: Newbie Alert
It does say supports 2a fast charge.. but the tech spec box above that says only use 1a [Image: smilie_denk_49.gif]

NEVER use a higher amp input than it needs, it WILL kill the battery and is unsafe. 
As the spec is conflicting I would opt for the safe bet of a 1a charger. If the apple one doesn't seem man enough a better one will be needed. I'm sure you'll get a recommendation of which one to buy soon.

Intelligent USB chargers with 100A would be fine, not a simple DC power supply

RE: Newbie Alert
Thanks for the replies.  I've always been confused on this subject.  I always thought that if you got a chargeresponse that outputed more than the device' battery could handle it would kill the battery.

RE: Newbie Alert
As far as I know the Coolfire 4 plus supports a 5v/1a charge. Now it comes with a cable supplied which you should use. I think the issue is definitely with your wall adaptor. The joytech wall adaptors that I use have a 5v output and work with every mod I own. Never gets hot. So just get a different 5v wall adaptor. You can certainly use a 2a adaptor.

Yes an intelligent charger will be fine, but as this is a global forum and people from all walks of life can be reading this I'd like to keep simple battery safety easily understood. Your first post didn't, to my mind, make clear ONLY an intelligent charger with excess amperage will be safe.

Discharge mah is not max input charge. If it were I'd be using 3a for my cells.. I don't,  because it WILL kill the cells and is unsafe.
