Green/Red Light and USB charging.
Review by Ancienton 1/30/11
I have found that depending on your PC's USB configuration and your device usage, the charger cannot get the full 5v it is supposed to if you have other things drawing on the same powered group of USB ports. Usually, each group of two ports will only have 5v available between them both so only one thing that draws power should be used in each pair at a time. My problem was that I was running the 650mah on the PT, AS WELL as trying to charge my 1000mah with both plugged into the same USB pair and the super charger would just never turn red unless the light on the base of my 650mah went out when it was fully charged. This is not a problem with the charger or your battery, it is a limitation of most standard USB ports. Unless you have a USB port with a little lightning bolt icon next to it, which is a newer USB passthrough port designed for charging USB devices and should provide an unshared and steady 5v, even if the laptop or PC is shut down.
When I looked into it and did a bit of testing, I found that I would need to use a USB port from another unused USB pair or at least one that is not providing power to something else for the super charger to work properly. I fully agree with SmokeyJoe that using the wall adapter is the way to go for charging the 1000mah batteries when you have access to a wall outlet, unless of course that is not an option, then try to make sure all your other USB devices that draw power are unplugged and it should go red and charge in a reasonable amount of time. If the light on the charger is green, IT IS NOT CHARGING! The light will be red until it is fully changed and then it will turn green to let you know it is fully charged and good to go.
