Allow me to make a brief crisp short review. Processing of the battery well. Contrary to some critics, I would note that the full state of charge of MiPow is indicated by a blue ring. Green does not exist. There the poor quality has been repeatedly criticized some adapter plugs here. I have to agree. The adapter plug for Samsung Galaxy I9000 / 9001, which included, is deficient. Do not sit and wobbles. This charging of the phone is constantly interrupted. Also damage to the charging socket can not be excluded, since the adapter plug to exercise through its length to a strong leverage effect on the charging socket. With the enclosed USB connector and a private original Samsung charger cable, it is stable and you can recharge, but it has quite a tangle of cables. In a lady's handbag but still acceptable.
