AC - USB adapter.

[Kent Jefferson]

Can I use an AC - USB adapter, rather than charging thru a usb port? I don't want to risk over-charging, or worse (a fire). My adapter looks similar to the one pictured, and says; Output: 5.0v ----2000mA. Maybe I need a 3.7v adapter?

What are you charging?

I'm charging a 750mAh battery.

That should be ok a laptop usb is 5 volt so the plug in unit is the same 5 volt and most charge off a laptop it just may be slow to charge

That's fine as was mentioned and may charge your battery a bit faster than your computer. That said I have no qualms about using my PC's USB ports for charging various devices.

Good to know! Sometimes - a USB port is not available, but a wall outlet is. : )
