Welcome to my review of the Anker PowerCore 20100mah external battery. I will start off by making some things clear upfront:

1. I was not paid to write this review, nor did Anker send me a review unit. I bought this powerbank with my self-earned money.
2. This review is completely honest.
3. This review is mostly based on my personal opinion, but it will give you a good idea of what the experience is like.
4. English is not my primary language, please forgive me for any mistakes.

Now that these things are said, let’s get into the actual review!

I’ve had several powerbanks over the past few years but none really seemed to surprise me. After a long search I stumbled on the Anker Powercore 20100. I was a bit sceptic at first because of how low the price was (£22 at time of purchase), but I decided to buy it anyways.
It arrived in 3 days, and the first impression was great! I really enjoyed the unboxing experience and you can tell that this is a premium external battery. I will divide this review in several parts so you can get an idea of how it preforms on different criteria.

BUILD QUALITY
I’m really amazed by the build quality of this powerbank. The Powercore has a solid unibody that consits of a hard plastic and will not break any time soon. It has also a nice texture to it (matte-black) and feels very good in the hand. It does not attract fingerprints like other Anker powerbanks with a glossy look. (Sometimes it can get a bit slippery though.)

WEIGHT
It’s a huge battery pack, so it is quiet understandable that this beast is not light-weight. It weighs about 350g. Telling of my personal experience, this does not mean that you can’t carry it around in your pocket.

******UPDATE********
I have changed my review from a 1 star to a 5 star Review.
(My Original Review is at the bottom)

I was contacted by Anker Customer Service who offered advice on what strength wall plug/charger to use with this charger.

I didn't realise that not all plugs are equal so I purchased a new plug from Amazon with the following specification.

• Input: 100-240V ~ 350mA 50/60Hz
• Output power: 12W
• Output Voltage: 5V 2.4A

& low & behold the charger, charged up fully & worked as advertised!

I love this charger now I can actually charge it back up.
It has a sleek design & comes with its own little cover/bag which I also put my charge cable into. It's so powerful, I have a iPhone 6s Plus & the charger can charge my phone quicker than my wall socket, whilst I'm still using it, on a battery draining game such as Pokemon Go! & it can charge it 6 times before needing a recharge itself.

JUST MAKE SURE YOUR WALL PLUG IS OF A COMPATIBLE STRENGTH.

My experience with Anker Customer Service has been exemplary. They went well above and beyond what I expected to ensure that I went away a very happy customer.
I will definitely purchase from this brand/company again.

----------------------------------------------------

I Really Wanted This To Work!
I have had 2 of these delivered in the space of 5 days & both have the same fault/defect.
My first was a white one - it fully charged then off I went.
Once the charge had been depleted I plugged it in to charge overnight. 12 hours later it was still just on 1 bar
So I plugged it in another socket just in case & left it for the day.
Still just on 1 bar. So I returned it & ordered another at a £5 increase in price.

The exact same scenario
What a disappointment I desperately needed this for my travels at the weekend.

Honestly the best charging brick I've ever owned (I own 4 of them).

I travel a lot with work and this now is my only way of charging my LG G4 while away from home. I charge it over a weekend (I'll come to that) and then its ready all week providing more than enough oomph to charge my phone every single night.

Charging... now this is where the device lets itself down a bit, with the advent of Qualcomm QC and higher current charging capabilities (I mean this will do 3A out of a single port) it's input port is limited to 1.5A. This means to charge the 20,000mAH battery will often take an entire day or near as dammit (so that's all night and all day). Great if you can plan ahead but a right pain if you're short on time. I understand that anker are selling newer units now that support the QC system allowing it to charge in a more reasonable time.

This aside, it's a great unit and I would recommend it to anyone.

Anker as a company

So this is a side note regarding my experience with the company for support. One of my power banks (not this one, it was an Astro 3 I think) after a year of use no longer would accept a charge and wouldn't respond to a shake to wake it. I thought it was dead and I'd have to buy a different unit. No... with Anker providing you've bought from their AnkerDirect store, all their kit comes with an 18 month warranty a quick email to Anker with my amazon order number and within 2 days I had a replacement unit in my hand. When asked what to do with the old unit they didn't want me to send it back they were happy for me to keep the faulty unit minimising hassle at my end.

I'm a firm believer in decent quality customer service and Anker has delivered on that front for sure.
