Pros: If your device is powered off, it will charge very quickly within an hour or so. If your device is powered on it will get a constant charge from the power bank and very slowly charge.

Cons: The connector to the adapters is very small, I was always worried it would break, there was nothing to lock it in.

Overall Review: My power bank actually short circuited after a month of use, I probably wouldn't buy it again, maybe from another company. It shorted by charging the power bank with a car cigarette charging port while I had a device connected to it. It didn't harm my device but the power bank smoked and had a bright flash, now it is unusable.
