- Reviewed in the United States on February 9, 2025Color: WhiteVerified PurchaseGood battery. Its heavy so not a charger to carry around in your purse or pocket but not an issue as I wanted one to use when plan to be in one location for an extended time(hospital, sitting at home & not near outlet, vacation) try to charge it when goes down just one bar as otherwise takes longer. I may be hurting it by not letting battery run down more but still working fine after several years.
- Reviewed in the United States on April 17, 2018Color: WhiteVerified PurchaseI ordered this Anker portable charger while on a visit in Ohio. I thought it would be useful for my return flight to Colorado to power my various devices. I paid extra to have the charger set delivered in one day to be sure I'd have enough time to charge the battery before my flight. The package arrived the next day. However, when I opened the package I discovered that although the battery was present in the box, the accessories box inside the main box was empty. The accessories box was supposed to contain the fabric travel pouch and, more importantly, the micro USB charging cable. Yikes! I immediately emailed AnkerDirect via Amazon asking if they could ship out replacement cable and pouch ASAP, but did not really expect to hear anything definitive from them until the next morning. I figured it was unlikely they would be able to get the replacements to me in time, so started looking around for a micro USB cable I could borrow that night to charge up the battery. Success! I found one for another device I that I was able to use to charge up the battery that night. (It had arrived with only a 50% charge.)
The next morning I received an email from Sharon at AnkerDirect. She said she had arranged for a replacement to be shipped to Ohio. I replied to her about borrowing a cable and so I was no longer in a bind about getting the unit charged up and asked if she could ship the replacement to my home in Colorado instead if the replacement shipment hadn't yet gone out. She emailed back that it had already been shipped, but she would send a second replacement to Colorado. Which she did. Now I consider that pretty stellar customer service! My only unhappiness was with the original shipment not being complete, but Anker bent over backwards to rectify the situation.
As far as the charger itself, I used it on the plane and at the airport for my laptop and my tablet. It worked fine. I'm quite pleased with it.Portable Charger Anker PowerCore 20100mAh - Ultra High Capacity Power Bank with 4.8A Output, External Battery Pack for iPhone, iPad & Samsung Galaxy & More ()
- Reviewed in the United States on June 7, 2016Color: WhiteVerified PurchaseI'm really not sure what I'm more impressed with, this product, or Anker support.
I was not paid, and did not receive a discount for my review, this is just a great product from a great company. I've bought several large capacity batteries recently for my MS Surface 3 (non-pro). While several of them have been equal or greater in advertised capacity, in testing they have faiIed to deliver anything close to the advertised capacity or full 2.4 amp charging rate. Additionally the built quality on all of them have been poor to middling. This unit is very solid, with no flex or poorly aligned seams. The case itself is a "soft touch" that is comfortable to hold and still nice to look at. It is about as heavy as a battery of this capacity should be, though I haven't weighted it, "Light weight" is not a description that fits. That being said, it's equal or lighter than the other 3 I've tried.
I had a 5 hour flight recently, and spent the whole time playing "Grim Dawn" which pushes my Surface to it's limit power wise. Additionally my girlfriend in the seat next to me was watching movies on her Galaxy Tab 7. When we landed, this thing still had 2 bars on it, and that was the defective one.
The original pack I purchased wouldn't finish charging, I left it plugged in for a couple days and it still wouldn't register as "Full". Anker support responded to my support request in under 12 hours, and replaced the defective unit promptly and politely. In a world of high technology, things will go wrong, even Apple makes a bad iPhone every now and then. The important thing is what the company does when something does go wrong. Anker support is as good as their product are. Buy this.
PS, If you think I got paid for this review, just go look at how crappy most of my other reviews are, and realize I like this product enough to write more than 2 sentences about it.
