Hi! I am a new member to the forums. I recently bought a Mophie Juice Air pack for my iphone 4. After the first time I fully charged the pack, a few hours into the day I decided to see if I had a full charge by checking out my LED's. To my surprise none of them came on! I tried switching the standby switch on and off, nothing happened. When I got home from work, I plugged it back in and instantly all four LED's lit up! I proceeded to unplug it and it worked from then on. I figured it was a fluke and disregarded it. But the same thing just happened again. This is getting frustrating. I have searched the forums to see if anyone else had this problem but couldn't find anything, unless I am searching incorrectly. I was wondering if anyone has had the same problem and can help me out, or did I just get a bad case.
