USB C – AA and AAA Lithium ion Rechargeable Batteries REVIEW
USB C – AA and AAA Lithium ion Rechargeable Batteries in AA and AAA size takes about 1 hour to charge from USB C cable. The out put is 1.5 volts. The capacity is rated in mWh rather than mAh, that being said when calculating the conversion.
The AA battery has a capacity of 1733 mAh and the AA has a capacity of 367 mAh. Much less than my Nimh batteries. Overall it works and is portable enough to carry the charge cable and spare batteries on a trip or if you ran out of power and needed to charge via usb this would be very convenient, even with less capacity than my 2000 mAh NimH batteries.
