Does this rapid charge on both sides? I mean could you charge pack itself rapidly using the 5X charger? And then use it to rapid charge the phone?
Also, this seems to be a generic battery pack that's sold under different brands. Found one on amazon as well -> http://www.amazon.com/iVoler-10000mAh-External-Battery-Charging/dp/B01A6HKP7E/ref=sr_1_1?ie=UTF8&qid=1459158924&sr=8-1&keywords=10000+usb+c
I have this one https://www.amazon.com/iVoler-10000mAh-External-Battery-Charging/dp/B01A6HKP7E
It's definitely pretty portable, it's not huge but I wouldn't bring it anywhere without a bag to put it in. Works as advertised though, no complaints. Comes with a USB c cable and a USB c to USB a cable too.
