This is a good quality and well designed 20100 mAh portable power bank which works and performs well.

The design is ultra compact and smart and the construction is durable and sturdy. This item will not fall apart or break easy.

The charge speed of this power bank is good and faster than the market average and you can do a number of charges before the power bank needing a recharge.

The power bank has a micro USB charge input port, two USB charge output ports, 4 small blue LED lights for power status and a on and off power button.

As a added bonus you get a free carrying/storage mesh bag.

Overall this is a good quality power bank which works and performs well, has a compact and smart design but it can take overnight to achieve a full charge after regular use.

I purchased 2 power banks recently, both similar prices, with similar respectable reviews, but that's where the similarities end.
One is a high end power bank with a 4.8 amp draw while maintaining a small profile, the other is clumsy, heavy and gets very hot.
Anker PowerCore 20100 is the best value Power Bank available under £25, it's much better than the Imuto Taurus X4,which was the other PB I purchased.
I wanted something safe to take it on a flight, which is compact, holds its charge well, and charges devices within a suitable time.
I have managed to charge a Go Pro Karma Grip, with the Go Pro Hero 5 attached, 2 iPhones, 1 iPad, and I still have 2 bars left, it's revolutionary.
I know now I can leave my hotel room and spend the day out,never having to worry about my devices losing power.

I have several Anker chargers including the Astro E1 (short journeys and very pocket friendly) and the Astro E4 more for long journeys & holiday travel.
Got this to last even longer if required. Only slightly bigger than my E4 and has a lovely matt finish. You ideally need to carry it in a bag as it is not pocket friendly but carries a massive charge that charges your phone and similar many many times over.
In response to those saying it won't charge, I thought I also had received a unit the wouldn't charge. I Was using my charger and cable that came with my S7 Edge. I changed to my charger from an earlier S5 phone coupled with an Anker PowerLine USB cable and it charges a treat. It does take quite a while though due the massive storage and it is well worth it.

Anker may want to look into other customers charging issues and offer some advice and also why it will not charge with my S7 Edge charger whereas all my other chargers will charge from it?

I simply love Anker products & this is another great one.

This will output 5v 2a on both USB charge sockets at the same time, it has a micro USB socket to charge the device. It has 5 LEDs on the front which indicate the charge level and there is a push button on the side which will turn this functionality on. It comes in a faux neoprene case which can also be used to store the 10cm USB to micro-USB charge cable that comes supplied with it.

I've repeatedly managed 8 full charges for a Sony Xperia Z1 and 8 full charges for a Sony Xperia Z5 Compact. On a long weekend away I was able to give a Sony Z5 Compact and a Sony Xperia Z3 5 charges before the pack was depleted. It can even keep my Asus Transformer T100 goes with several full charges.

It weighs less than you would expect, but I'm sure sure if that is because it is quite large.

Best charge bank I've owned

Brilliant portable battery. Fantastic amount of charge for a device so light. So much lighter than any other I've owned.

My only niggle is that it only has 4 LEDs to indicate charge. But that means each one is about 4000 mAh. So if you can see three lights, it means there's anywhere between 8000 mAh and 12,000 mAh available, which is a lot of charge to be uncertain about. Same goes for when you are charging it, it's not entirely forthcoming about how far it's charged and thus how much longer it might be until fully charged.

However that's a minor wrinkle in what is otherwise a fantastic product. Seriously, for the amount of charge in this thing, it's light as a feather. I've owned portable chargers with half this capacity that weighed a lot more than this does. Well worth the money.

Absolutely amazing performance from this product. It has so far out performed all expectations.

The charging speed is lighting fast as advertised, the device feels compact and can charge two devices simultaneously as advertised.

The size is reasonable and the provided case/sleeve is good quality and strong, if a little big for the product it keeps it safe and scratch free in my bag. I carry the product with me everywhere now and it never fails to deliver. Charge once ever 2-3 weeks and use it maybe ever other day for an iPhone 5. So far I'm getting 10 full charges of the phone for every full charge of the battery pack.

The pack is quite slow to charge being so high capacity - I've been charing it from a laptop port over night and it doesn't quite fill it up over an 8 hour sleep. I would suggest investing in a wall plug/adapter for the USB plug if speedy charging is required.

Would recommend this to anyone. The weight of it is quite high at first however when kept in a bag it's easy to get used to and you don't notice it after a short while. The device is not too bulky and fits nicely into my Jeans back pocket when walking around for really easy charging.
