Anker Portable Charger PowerCore 20100mAh - Ultra High Capacity Power Bank with 4.8A Output, External Battery Pack for iPhone, iPad & Samsung Galaxy & More (White)

I was really impressed with the Anker 20000 mAh I recieved. Everything from packaging to the build quality was very, very nice. However, when I charged my ipad air 2 and toted it around the house as a test, I noticed that the unit itself had gotten extremely warm just after 30 minutes. I haven't had any trouble with charging smaller items like cellphone, but I had really hoped that this larger capacity battery would have solved all of my charging needs, but it falls short on my most expensive device (ipad air 2).Benefits: it works great using my usb led lightbulb (shines very bright) and charges my samsung or iphones At the same time.I am tempted to get a second unit just for my cellphones and emergency lights, but I am hoping to do more test charges with my ipad air 2, hoping that I can discern why all the heat build-up while charging. I will update accordingly.*****10/11/2015 UPDATE*****Thanks to Anker's prompt response to my unit's heat problem, I will be changing my review to 5 stars. ANKER's customer service contacted me via email to assist, and within a week they initiated sending me a replacement unit as well as a new ANKER Lightning cable in case my cable was causing the heat problem. I think I may have had a bad unit but with ANKER's customer service, I have no doubt that in the future they will help remedy future problems. Thanks ANKER! Your customer service definitely made my day.I have a collection of RAV and ANKER external batteries and a RAV solar panel, and I love putting them to use! I live in a remote area so I feel confident in my battery backup needs. My next purchase will be ANKER's 20 watt solar panel to hopefully charge up my external batteries more quickly :) Happy charging, everyone.

I’ve had this AMAZING Anker Portable Charger for almost 3 years now and I still have nothing negative to say about it! I take it with me everywhere I go and I never have to worry about a low-battery phone. I bought a Qualcomm Anker Single PowerPort along with an Anker PowerLine Lightning Cable and whenever the charger becomes low, I just plug it in with the PowerLine and PowerPort overnight and it’s fully charged in the morning. A fully charged charger gives around 8 full charges for my iPhone 8 and it always charges fast too. For almost 3 years, I’ve never had one issue with my Anker charger and if it were to ever kaput on my one day, I’d buy another Anker charger in an instant. The material that was used to make the charger is clearly extremely durable and very high quality. I’ve dropped the charger a multiple times and it’s never hiccuped. The casing material is so durable that it barely gets any damage from the drops, even with the travel pouch on. The charger is not light but also not heavy—It’s at a good weight for a quality charger. I would hands-down say that this is the best portable charger anyone can buy. The price doesn’t break the bank and the amount of MAh you get for the price is unbeatable. My brother recently bought one like this for his Switch and it’s good to see that the quality Anker puts out has not faultered. I’d no doubt recommend this to anyone and would buy another charger from Anker in a heartbeat.

I saw the picture and thought oh what a cute little charger with amazing juice.When I opened the package, I was very surprised to find a huge thing bigger than my Note 3. (Longer but much narrower)I thought how the heck am I supposed to carry this around, I wanted something "portable."However after taking it out a few times I grew accustomed to it. It carries enough power to fully charge my Note 5 (no longer 3) at least 3 times starting at 1%. I haven't calculated how long it takes for it to fully charge, but it is enough for me to be satisfied.Some cons are that it takes forever for the actually charger to charge. I can't charge it with any other cable other than the one it comes with. (A detail I learned the hard way after connecting it to a different cable only to find that it did not charge at all overnight.) I'll just connect it to a wall charger and forget about it until the morning after which I can just slip into my purse and head out.It's bulky, but it does its job well, so I'm not complaining. It's much more reliable because it carries more power and I don't have to recharge it as often. To each their own.
