Top Customer Reviews
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.
Is very useful if you punish your devices all day long, you wont regret it. Besides, anything more than this size is not so handy (imo). I'm still testing the charging times and how much juice i get, i'll review this later.
However the only issue that i see is that the supplied usb/microusb cable seems to take notoriously more time than using my nexus5 cable. I'll try different cables to make a fully review
There are tons of external batteries out there but for now, i am really satisfied with this one.
Let me count the ways. Although you fuel my addiction in which I think I need an intervention, you keep my gadgets going all day long. I first came into contact with Anker back when I had a Galaxy S3 phone and bought an "el cheapo"extended battery. Had I known my original purchase was the start of a beautiful yet enabling relationship I would have bought stock! Last year I purchased their Anker 13000mAh battery pack and it's still kicking. Still charging my Android phones, my iPhones, and my tablets. Recently I bought my fiance her first Anker product so she's able to carry her charger in her purse and never be in a situation where she's without battery (and it's pink, so thats a plus).
Anyway, I'm a sucker for new gadgets and just picked up two brand new battery packs for myself. I bought the Anker (2nd gen) Astro E5 and (2nd gen) Astro E1. These things are GREAT and the E5 packs 3,000mAh more than my first. The sizes are excellent and easy to throw in a bag, or even a coat. They charge your devices and they're high quality. I really don't know what else to tell you. The E5 is about as long as my iPhone 6 Plus, 3/4s as wide and twice as tall (with two Apple leather cases)
Now Anker, a private message. Please, oh PLEASE loose the glossy, messy finish. These things attract finger prints and dirt smudges like crazy. Crazy enough that after i've used it a few times it looks like my toddler has been playing with it while eating dinner. They also scratch very easily. While not affecting overall usage, I just like my things to look as nice as they work.
Anker, You keep updating and upgrading and i'll keep being a customer.
