Anybody hooked up their external battery pack

[hoben02]

Wanted to know if anyone has seen issues with charging thru a mophie battery pack. I need one since I'm a heavy user of apps like shopkick and checkpoints
I don't expect any issues with an iPhone 6 but asking

I use the juice pack air on my iPhone 5s and have had no problems. I haven't used the separate plug in battery packs though.

Ok tested out a generic cable and mophie powerstation on iphone 6 no issues

I've got a limefuel that works great with it. No issues.

Have an older NewTrent battery. Works. Also, brand new JBL Charge 2 bluetooth speaker charges my 6 Plus nicely.....
