Power Bank.Anguo 3000/5000mAh Ultra Compact Power Bank Portable Charger Powerbank External Battery Charger for iPhone7 Plus 6s 6 Plus, iPad, Samsung Galaxy, Nexus, HTC and More (A03-Black)

I have this connected to the Mosiso bag with USB port for travel. Definitely gives you the needed juice to keep your devices going on the go when you have to have it.

Great power bank. Charged up quickly and seems to hold the charge when not in use. I also liked that the unit did not get hot while charging my phone like other portable chargers that I have owned in the past.

Works very well but takes a long time to charge.

Stopped working after the first week

I love this power bank.It was comfortable enough to hold in my hand together with my phone.Very GOOD.

This arrived early. My nephew was very happy with it.

Super handy.  I have found that it charges up rather quickly. I use it to charge my phone at work because I have no adapter where I work. 5000 mah is enough for me. I can charge my phone fully.
