good unit... included cable not so much
Kenneth Vanstory (Benicia, CA) 12/1/2017 11:35 AM
I just received this unit... seemed to charge very slowly, but reached full charge overnight. When I tried to charge my Samsung Galaxy 4 phone I got the "To charge faster use the original charger" message. I used a known good cable... didn't get the message and my phone is charging rapidly... great unit, bad cable... needs investigating by Tenergy.
Great power bank

I ordered 4 of these since I use them a lot for Go-Pro cameras and phone while riding. It will keep my Gro-pro going ALL day. This is a very good deal for the price (VERY GOOD). It is small enough to carry every day as a just in case. The only Con I have with the pack is the recharge time. Not really an issue since it normally can fully recharge overnight with a good USB wall plug. Be careful if you are using a really low amperage output charger because it can get really warm and could potentially overheat in a worse case event. Over all the best buy on a power bank that I have found yet.
