I got X4 13000mAh version, I charges my iPhone 5 and iPad mini, many times it stoped charging at 95-97% level. Is it considered normal or defective?

This works better than anything I have tired before. You won't regret buying it. Go for it......

No this is not normal. It remains 100% even after it charges a single mobile. Try to charge it 1 more day then judge.

I've had no problems with mine whatsoever. I've owned this for nearly a year. I charge my iPhone 5S at least 4 times a week from a 10% charge. The charger still has more than 1/3 charge left at the end of the week when I recharge the charger. I love this thing so much I bought one for each of my sons (2) and recommend it to my friends at work.

No, mine wouldn't even charge one. When I looked, the ipad indicator said "not charging". It was at 70%, but I don't know where it was when I first plugged it in. Neither outlet worked - same message for both. Maybe I just got a bad unit...?

Mine also never shut off which led me to believe it never charged to full. I tried charging my Nexus 7 and it only charged it to 93% before running out of power. Maybe I got a defective unit

Well, I have charged my ipad with it several times since I got it and have had no trouble at all. I got one for my mother and she uses it all the time with no problems. I have used it with my iphone 4 as well. Not sure what the difference is supposed to be.

I believe this is normal operation. It did that for me with the original power supply. I think it's just to let you know when it's charging vs. battery mode. Hope that helps.

I was able to fully charge two iPhones and still had juice to provide some charge to a half-depleted iPad before needing to recharge it...hope that helps

Once fully charged "before you leave home", I have had mine keep the full charge for over a week. And when I've used it to charge my dead phone, which it charges fully and very quickly, I have I would say a 50% charge left, if not more. And that leftover charge does not disappear. Let's put it this way. I charge my phone and Itouch far more than I do this unit. Don't forget, the idea is not that it replace your electricity mains! As a standby, I find it excellent and would highly recommend. FYI, I've tried using it to charge my iPad Air. This drained the unit of any charge and charged the ipad about 20%. So it's not efficient for larger devises. Once fully charged "before you leave home", I have had mine keep the full charge for over a week.

I charge my iPhone, iPad at the same time and have never received a slow charge warning. I have not tried 3 devices at once, though. Hope that helps.

If the battery was fully charge then I think it not a battery problem. May need contact apple store for this problem.

It has charged my iPad 4 and iphone 5 simultaneously 2 times and then the iphone a third time with a blackberry all on one charge. When I charged it, it still was not out of charge.

it is normal. all charge will charge above 1.2V (NiMH rated) for a while.. and that 1.45V will drop back to 1.2~1.25 quickly after you use for 10min.

I didn't have any issues charging it,I had Iphone 5 it worked fine, now with Iphone 6 plus also it works fine, if it doesn't work just send it back for replacement.

I have had mine over a year now and have not had one problem and highly recommend it. I think that the not certified is that it's not an Apple approved device by Apple. Just like charging cables, I needed a longer cable so I bought some cheap ones off groupon, woot etc. and they all work fine at half the price or less.
