I got this battery pack as a token of appreciation for attending the S7 launch. This is greatly appreciated because I have been needing a battery pack. This is not the more recent fast charging model which I would recommend if your phone supports fast charging. It has the same form factor as the S6 edge and comes in two colours, silver and apricot. It is lightweight and thin and has a four light LED power level indicator. According to the website, it uses rigorously tested and approved battery cells that provide you with a more reliable and safer charge. It is compatible with any phone that uses micro-USB charging. Charging my S6 edge+ (3000 mAh) took about two hours and left the battery pack at 25%. So I would be able to get one full charge and then some. It takes about three hours to charge the battery pack. It does get slightly warm when in use. Look for it on sale where you should be able to get it for less than listed on the Samsung website. Your phone comes with features to save charge and I’ve read that using a black theme helps. We all wish for higher capacity smartphone batteries but for now a battery pack is a good way to get extra juice especially when you are on the go.
