I am happy with the battery however, using this charger to charge the battery back to life, I have to wait for 16 hours before it gets fully charged.
I needed some AAA rechargeable batteries to use for my digital camera and my wireless mouse so I invested in this charger because it is less expensive than other battery chargers I could find. My wireless mouse consumes a lot of battery life so this charger is not the kind of charger that's for me, also my digital camera can consume the life of a fully charged GP 800mAh battery in a few hours and having to wait 16 hours before I can capture some moments once again is a little bit of a hassle on my part.
The design of the powerbank though is nice, I love the contours, it is just a waste that it will take too long before a GP battery gets fully charged. MAybe if I use a different brand of battery to charge in this charger since the 16 hours is actually what was stated in the battery anyways. Maybe the charger will work wonders, perhaps a bigger miliAmps per hour will charge faster or perhaps slower.
All I know is that everytime I charge my batteries with this so called power bank, I had to wait overnight.
