Problem with External USB Power Pack

[MetalMarcus]

So I recently bought a PNY 7800mAh dual port power pack because I travel a lot with work, and it doesn't seem with work with my phone at all. I started out with 4.1.1 rooted and it didn't work. So I erased everything on my phone, unrooted it, and updated it to 4.3 and it still doesn't work. Also have tried it on other devices and it works fine, so it seems like the problem is with my phone. I use multiples types and kinds of chargers too and they all work fine, I've never had a problem with charging my phone. Just these power packs don't seem to like me,
Things I've tried:
Different cords while testing them out before hand
Specific ways of plugging it in and turning it on
Other power packs (I tried a bunch at Future Shop and none worked)

Any advice would be super helpful, thanks!

Buy extra batteries and an external charger.

Not really a solution.....I have an extra battery, but I have my phone in a lifeproof case, which is kind of a bugger to switch out every time. As for an external charger...Isn't that what a powerpack is?

That's very strange - any of those power packs (including the one that you purchased) should work just fine. They all should be providing 5V @ 1A (or more; it doesn't hurt to use the higher capacity port) and that should work regardless.

I think there's a problem with your phone: perhaps just with the micro-USB port, perhaps with the charging circuit itself. You could try getting the micro-USB port replaced (ex: http://mobiletechvideos.mybigcommerce.com/samsung-galaxy-s-iii-usb-port-repair/) and see what happens.

Thanks, I think I'll just buy one (or 10 apparently) off ebay and do it myself. Could be a possible solution. I've had the phone for over a year now and use that charge port a lot
