Im not sure why at the time of this writing this listing the owners manual and the manufacturers website all say usb 5v 2a x2 but that is not correct

For me the indicated charge current tells the most about the remaining charge time when using this charger you can see the initial constant current around 4a then as the battery reaches its target voltage the current will taper off over time to something close to zero indicated shortly before charging completes

Charging one two or all three batteries plus usb has no effect on the charge rate

This is cheap and works

This does not have any discharge function or any function that allows a partial charge for battery storage

While i didnt time everything the energen topped off two in half the time the stock charger took to get the single battery to full
