On one occasion, before I had this unit, my wife and I were waiting for an Uber Driver around 10p and the phone went dead, so we lost the ride. We had to rely on a regular taxi, at over twice the price. If I had this charger on that occasion, the savings would have paid for the unit.
I'm on an iPhone 7 now, and have had wonderful results with the battery life, however, if I know I'm going to out and about in an extended period of time, you'd better believe I'll have it with me. You Never Know!
The unit is now just shy of 2 years old and is done. I tried boosting the charge on my iPhone Xs, it was at 70%. I got it up to 82%, the Anker dropped to one flashing bar and got really hot. Looks like the end of the line. It was nice while it lasted.
I plug the pack with a full charge and it quickly drains in less than 5min raising the iPhone battery by ~5%. When I charge back the pack it immediately gets to three bars and to a full charge within less than 5min. This behavior indicates poor battery management. The iPhone seems to ask for too much power which leads the battery to overload and to provide a low-charge signal when there is still plenty of power available in the pack.
However, an identical pack being used with the Android phone also drains quickly, but in that case it gets to about 25%, which is somewhat more useful. This indicates poor battery life.
About 3 months ago I bought it as an extra juice for my phone but never got use it thoroughly when it arrived (my bad). I did some quick tests, charged it and never minded it for a while. It turns out it was charging for a couple of seconds and as soon as my screen was off it stopped charging.
Fast forward to a coupe of weeks ago. I actually needed to charge my phone and I noticed that it wasn't working. Worst of all, it wasn't working with my phone (Nexus 5X). It worked with my kindle devices, my partner's phones (Nexus 6p and Samsung 5S), and pretty much any other device in the house.
I reached to Anker's customer service through email explaining the situation. They asked me to test a bit to discard a possibility of faulty cable or that my phone was actually defective. That out of the way the sent me a new unit in about 4 days.
They were nothing but polite and understanding. Guess who is only choosing Anker from now on?
P.S.: If you are from Anker, give a big thanks to Shae for me, impeccable job.
If you buy this:
1) only expect it to work for up to 12 months and then die!
2) And make sure to monitor the 12 month warranty closely and get it replaced before the warranty expires!
despite only using this a handful of times over the course of a year, the battery just stopped being able to hold a charge conveniently just after the warranty expires.
Customer service is very strict on only helping if you are within the 12 month warranty, even though they admitted the battery was DEFECTIVE.
Lesson learned: I will not buy their batteries anymore :-(
Top reviews from other countries
After posting about the issue I was contacted by Anker Support. They apologised and shipped me a new 6700mAh charger. This thing is AMAZING. I decided to give it a test to see how it works. I have charged my s7 THREE times to full from about 20% without recharging the pack and its now on one bar. Will def recommend this model over the 5200mAh. Great product may win some over but great products and great customer service guarantees a returning customer.
Bought this in February 2017 It is now December 2017. It started off great and would give me an avg of 1 and a half charges on my s7. Now it barely charges from 20 to 70 % without dying. Buy at your own risk as it really doesnt seem to last long Especially looking at other comments on orders.
It's quite compact as the description says. They're right, it's about the size of a Coffee Crisp - thinner and shorter, but a little wider. Feels well built too.
It functions perfectly fine, however there's really no quick charging to speak of. With most Androids these days getting larger batteries every year, even the 2.1 A charger port in this guy can feel a little slow. You need 2.4A or a quick charging technology of some kind. It will charge you phone but don't expect to jump from 0 to 50 in half an hour, as some phones claim.
Overall a great purchase but it just charges a little slower than I'd like.
Update: Anker reached out to me and replaced the micro usb cable with one of their sturdier versions. It's appreciate that their support reached out to solve the problem.
Updated July 19, 2017. The battery is not holding a charge anymore. It only lasts 30 minutes charging my iPhone 5S and gives me only half a phone charge now. It didn't slowly lose its functionality, it just happened over night. The first 15 minutes its full bar after a full nights charge; then it all of a sudden dropped to 2 bars (out of 4). Then the last 15 minutes, the last bar blinks (indicating extremely low charge left); and then just dies. Super sad because this was a beautiful size. No dents or damage to the battery pack, so I don't know why it just died.
Old Review (Nov 2016)
Works as advertised. Charged my iPhone 5S pretty quickly. Thought this would solve iPhone's issue of using china version cables by increasing the amps to 2 or higher (old battery pack was small and only did 1 amp). But that didn't help... iPhone wants to see their own certified cables used. Battery pack fits in my jeans pocket no problem along with my phone in it too. Bulky, but fits and isn't too uncomfortable. Takes a bit to charge, but that's expected for 5200mAh. I also like the charging input is far away from the output so i can charge the battery while charging my phone plugged into it. No flashlight like my old one, oh well.
