It boosts your phone battery charge about 50%, maybe a little more, if freshly charged. It takes about an hour to fully discharge/boost into the phone. That's pretty efficient for a 50% charge up.. It doesn't seem to retain a full charge very long though.. After a week, it was down to three lights or 75% charge.. If you do not use a phone case, then it will snap/secure to the micro-usb port pretty firmly. Enough to not impede phone use. However, if you have a phone case, then you will have to utilize the 1/2inch micro usb port extender it comes packages with.. I saw this in a catalog for $40. Don't think it's worth that though. More like $10. I would take two of these on a trip or hiking trip as a good backup. Small & convenient is part of it's appeal.

This portable charger is perfect. No cables needed and it stays plugged into my Note 5 till I unplug it. It's so good I want another asap.
