Just bought the KCB-L2B day before yesterday from Viewnet. Charge it over night then use it to charge my bb 9900 yesterday. Today tried to charge again today but it turns off after 5sec. I am assuming it does not have enough power to charge the 2nd time.

With the 9900's battery rated at 1250mh, I would have assume the KCB-L2B's 5000mh would be able to charge my 9900 at the very least 2 times.

Any one have any idea why it only manage to charge only 1 time? Or should I sent it back and exchange for another unit?
