Portable USB charger

[DavidDLC]

First time I want to buy one of this units, I have reviewed some of them at Amazon, and I thought I will get some good information from here.

I want to buy this, to connect some small electronic projects that work at 5 V to show to possible clients. Something like a sensor reading using LCD and small stuff like that.  And also take advantage and charge my phone from it

Can you recommend some good brands ?
