Reviewed in the United States on January 27, 2019
Color: WhiteVerified Purchase
I love Anker products!!! I have purchased several accessories from battery chargers to car storage card adapters from Anker in the past. This particular charger didn't disappoint. I purchased it for my 13 year old daughter to keep in her mini backpack because she frequently asks for mine when her battery runs low. My daughter is very particular about product aesthetics so I'm always looking for something that suits her high standards while meeting my equally high standards for quality and safety. This product meets both! Now if I can only have her remember to charge the battery before leaving the house. : )

5.0 out of 5 stars Real Good Device
Reviewed in the United States on January 17, 2018
Color: WhiteVerified Purchase
I recently needed to replace one that had served me well for several years, but was no longer holding its charge as it once did. That gave me the opportunity to thoroughly investigate what is available today, and I was both pleased and surprised at how far this technology has come since I got my first "portable" battery. I travel nearly every week throughout the world, but with seat power being unreliable, even if it is on an airplane, I need something that can keep my tablet working (Samsung S2-8) for 12-14 hours at a time. and be small enough to not require a separate piece of luggage in order to transport it. This device is real good for that specific mission. Its tiny! So small that when the tablet's battery gets low I can plug it into one of these and it will both charge the tablet's battery while at the same time keeping it up and running without getting in the way. I actually got two of them. One for use primarily by the tablet, and the other for keeping my phone or Bluetooth headset "topped up".

In testing out its capabilities, I let my tablet run down to 29% battery level. It took 2 hours and 15 minutes to fully charge. Then it took about 3 hours to recharge using a conventional, non-smart usb charger. So am I happy with it? Absolutely!

5.0 out of 5 stars Great emergency charger for the price
Reviewed in the United States on January 8, 2019
Color: WhiteVerified Purchase
Very happy with the product got one for myself and another for my girlfriend. I use a Samsung s7 edge and she uses an iPhone 6 and she loves using that even at home since it chargers faster than her regular apple charger. For android users looking for a fast charge charger this wont do it but it does still charge my phone from about 20% to near full in around an hour and 40 which is pretty much the same as a fast charge even though the phone does not indicate that its being fast charged. The glossy plastic is not great but not much of an issue to me or her. THE ONE DOWNSIDE is the input of 1A which does take the unit a bit longer to charge but again not a big issue since I just leave it charging when I get home if needed for the next day. TO THOSE HAVING ISSUES CHARGING THE CHARGER: try using a 1A USB wall charger. I tried using my Samsung wall charger with it and had issues with it charging up but once I switched to a 1A wall charger had no issues at all.

Reviewed in the United States on January 21, 2020

My old iPhone had a dying battery that would discharge extremely quickly and required the use of an external to make it through the day. I used to carry around a 10000mah+ battery, but recently bought one of these and have found it more convenient than it's larger brother. It can last through a day or two of heavy use, weighs a fraction of the large capacity battery and can easily slip into a pocket. If you just need a backup device to charge your phone with, this is a great minimalist choice.

4.0 out of 5 stars Great Product, Great Warranty, Horrible Customer Service
Reviewed in the United States on January 5, 2018
Color: WhiteVerified Purchase
Anker makes the BEST POWERBANKS. I love thier Power IQ technology. Being an iPhone user I think the IQ tech chargers my iPhone faster than any other charger. I think the PowerBanks with an IQ 2.0 port charge my iPhone faster than a standard wall charger. I have had some problems with the QuickCharge port (QC3) it only trickle charges my iPhone, I think it's made for Samsung phones but not sure. Just be sure to check the PowerBank ports before you buy... iPhone user should look for Power IQ 2.0; Samsung users should look for QuickCharge (QC3).

Size does matter, you need something for the weekend camping trip get yourself a larger Powercore 20000 mAh or higher.
Need something to just get you through the day the Powercore 10000 mAh will be more than enough.
My wife uses the Powercore II 6700 with her iPhone 7 and it gives her a full charge fast.

Love Anker Products. Anker stands by their products and replaces anything for free as long as it's under warranty (usualy 12-18 months depending on the product). There is 1 thing I hate about Anker customer support, they are completely impersonal. You'll read this grievance in my most of my recent reviews, I'll explain and let you decide for yourself if Anker Support could have, should have, treated me better. Just bought multiple items as Christmas gifts for 16 family members (16 power banks, 16 lightning cables, 8 micro USB cables, 8 Wall Chargers, 5 Car Chargers) Not only did I spend a lot of money but I gave Anker 16 new customers that are already purchasing more Anker products. So when my personal 6ft Powerline+ lightning cable broke after a few months of minimal use (exposing the wire) I sent in my request for a new cable. I explained how much I love Anker, how I just got my entire family Anker products and got Anker a bunch of new customers and I was surprised the cable broke so easily. I asked if they could replace my cable with the 6ft Powerline+ II, figuring it may be more durable. Their reply was surprising, they wanted to refund me for my cable so I could purchased the newer cable. They did not offer a discount for the new cable, so essential they were not willing to give me the newer cable for free, it would have cost me a few more dollars and honestly I can't imagine it really costing Anker more than a few cents for the upgraded cable. This is such a huge turn off, I'm the customer you want, not just a guy who buys a cable, but someone who buys many, many products from you, gives your products to all of my family members, and promotes your products to everyone... So many of my friends have also gotten Anker cables based on my recommendation. Highly disappointed in your customer service skills Anker, still love your products but I don't plan on promoting your products until you learn how to treat your GREAT CUSTOMERS BETTER.

5.0 out of 5 stars Good power for its size and weight
Reviewed in the United Kingdom on January 26, 2019
Color: WhiteVerified Purchase
Does everything you would expect - charges my plus sized phone almost twice, nearly charges my tablet once completely. Nice output to size/weight ratio, easy to drop in your bag (laptop or handbag).

The only downside is that it won’t charge a device while being charged itself like the last aux battery that I had. I know that sounds like a dumbe idea, but it actually worked out better than using a higher-powered charger on just one item when you’re unsure of the next plug you’ll see.

Comes with a bag and a decent quality cable. The gloss white finish would scratch without the bag.

Nice battery, well made, worth the money IMHO.

Reviewed in the United Kingdom on June 6, 2018

What can I say? It's an Anker product. You get quality, reliable products but at consumer-friendly prices. The upgraded capacity makes what was an already great deal even sweeter. The charger has an excellent build quality and the glossy plastic finish looks really, really good - especially in white. This particular size is a great balance between size/portability and charge capacity, although I'd recommend any of the Anker portable chargers. It's compact and lightweight but still holds ~ 2 full charges for your smartphone - one of the best size : charging capacity ratios for any portable charger on the market. With the added reliability given from the brand name and fantastic customer support, you can't go wrong with this charger.
