Why is my Portable Charger Suspending my phone while charging?

[AC Question]

Portable Charger Suspending my phone while charging.

I bought a portable charger for my LG Optimus L70 D321 but when the charger is hooked up to my phone I keep getting "Suspended While Charging" messages. It keeps disconnecting and not allowing me to use the phone.

The USB cable works fine with my phone connected the the wall just not with the portable charger. It's a myCharge Model AM22B-A I bought from Best Buy.

Welcome to Android Central! Keeps disconnecting from what--the internet? Are you able to do anything at all on the phone when it's suspended?
