USB Charging
Maybe a dumb question just want to be sure; I have one of those Small Quad Copters with 3.7v/100Mah LiPo Batteries that uses a USB Charger Cord to charge them with; I have been charging through a USB Port on my Computer; I have read that you can plug the USB Charging Cord into a 5.0 Volt charging adapter used to charge Cell Phones that Plug into normal 120AC outlets; my question is, does it matter how many amps the Cell Phone Charging adapters are rated for, I have several all 5.0V adapters ranging from 730 mA to 2000 mA.
Thanks.
Thanks.

A 5v source is above the maximum 4.2v lipo voltage.
I'd have to guess that there is something that limits the voltage actually
applied to the battery. Assuming this, any adapter that can provide at least 100ma
at the needed voltage should work.
