Pack does get warm/hot when charging an iPhone6 and iPad mini simultaneously. According to the Jelly Comb Universal USB Power Multi-meter it restored 15221mAH capacity. Impressive!
One thing to note about recharging this thing- it will start off restoring capacity quickly (5v @2A) but as it gets past 8000mAH the charge rate slows down significantly. At 11000 it would only accept at .30A (this was after about 7 hours) which means the first 1/2 or so accepted capacity quickly, but the latter half took much longer.
Tested with the Globe Electric 7791301 6 Outlet 2 USB Surge Protected Wall Space Plug and factory Apple iPad charger to verify that the battery had slowed its draw down.
Overall happy with this battery pack. The sweet spot as far as time/efficiency goes is to use it to 10% and recharge to 70-80%. To recharge the last 20-30%, it takes much longer and only makes sense if you have the time to charge for that long or absolutely need the full capacity.
Now with that out of the way let me say that like most people who run a "smart" device life, I found myself needing more juice on a daily basis. I had researched plenty of battery packs in an attempt to get the most out of my hard earned cash.
When I came across this particular battery pack I picked it up after researching and reading all the previous reviews. My experience with it initially wasn't very satisfying. I charged it as per instructions yet when I went to use it, I found that it barely charged my iPhone 6+ to 40% before completely dying.
I was going to just send it back to Amazon for a refund but instead I decided to contact the manufacturer by replying to their email regarding my purchase. I emailed them at 8pm and when I woke the next day I saw that they had emailed me around 4:30am.
Long story short they helped me trouble shoot the issue I was having. They asked how I had charged it and said that the charger should be at least a 1.5A charger. I was using my iPhone charger (white cube). I tried again with a 2A charger and it's worked amazingly since then.
I'm extremely satisfied with the battery pack and highly recommend it.
Also the fact that their customer service was so quick and accommodating was very refreshing.
Don't hesitate to pick it up. I already have 3 friends who are going to pick one up.
I bought this portable charger over other popular ones (mainly mophie) because not only was it recommended to me by my sister who has the same exact one, but the price was too good to turn down. I paid over $100 for my mophie battery case which only had about 2500mAh. This portable charger has 16750mAh, and is available for a third of the price. If you solely want a cheap(er) portable charger with lots of charge time, I suggest you going for this case. However, I bet there are better options. I recently purchased an iPhone 7 Plus and wanted a portable charger in case I didn't have the chance to charge my phone. I got the package in about 3 days with prime and the packaging was great. You had the instruction manuals, a small thank you for purchasing the charger, a very convenient mesh case (because the charger WILL scratch quickly), portable charger itself, and the USB cable for it.
I immediately began charging it. It took about 4 hours with the iPad charging brick to charge fully from what I am going to assume is halfway. The charger charged my phone about 4 times before needing to be charged again, which doesn't make any sense because the battery on my phone is 2900mAh. 2900x4=11600. I should be able to charge my phone completely from 0% about 5 times, yet I was only able to do so 4 times at most, which was very disappointing. It also doesn't charge from one of the ports... If you only use the left plug, it won't charge your phone. However, if you use the right plug AND the left plug at the same time, both of your devices will charge. I don't know how to feel about this. Maybe it's just mine and others may not have this problem.
It's compact which is nice but this definitely isn't something you're gonna be carrying around in your pocket. A purse or backpack maybe, but not your pocket. Overall, I'm not too impressed.

It is big which is understandable considering the high capacity.Read more
