By USB charger, I mean a battery like http://smile.amazon.com/gp/product/B00O1...ge_o09_s00 that is meant for charging cell phones. I bought this battery last year. I ran a Raspberry Pi, with a USB wifi card, driving a 2.8" TFT screen, and ran it for at least 8 hours (I don't remember how long it rang, but in theory it should run about 13 hours). The particular pi/screen/camera/wifi took about 750mA of power.
Now, the the pine64 is different from the Raspberry Pi, so your numbers may vary, but the idea is to use a battery that provides USB 5v power instead of a lipo (it likely has a lipo inside of it). The only wrinkle is some USB batteries will only deliver high voltage for particular devices and a device that doesn't have the proper signature will only get 500mA (which may be too low for the pine64).
There are many different USB batteries out there. When I bought the battery, the 16,000mAh batteries were at the top of the heap, and now 20,000mAh can be found and a few that claim specs even higher (though note, a lot of battery makers lie about the actual capacity).
