5.0 out of 5 stars Very adaptable 11 May 2014
By TAS55
Size Name:13000mAh Black|Verified Purchase
A solid product and is very adaptable. Previous battery backups I have owned have only supported certain Apple devices. This has the power, sockets and adapters to provide additional power to iPhone, iPad2 and mini, Samsung smart phone. On a long trek in Pembrokeshire this device charged up fully two mobiles and an iPad 2 and still had 50% power left in it. I was very impressed. It's not too big and fitted in my coat pocket as it charged. The casing is strong and showed no sign of over heating. It's the speed of the charge that really impressed me. Now I have one battery pack to support all devices as long as you remembered to take the necessary cables with you!

5.0 out of 5 stars Beautifully designed and packs a huge punch! 13 Sep 2014
Size Name:15000mAh Indigo
Don’t know about you, but I’m on my mobile or iPad 24 x 7. Of course, this also means I can’t spend more than a day away from a power socket - that is until now.

Here’s why…..

What is it and what does it do
This remarkably powerful (and beautifully designed) little box is an external battery charge pack for an iPhone or Android Smartphone or an iPad or Android tablet computer. Basically, if you’re out and about (on a long rail journey or away camping or at a rock festival), you can re-charge your phone or iPad loads of times back to full charge.

What's it like?
It’s a chunky little device which comes in a cool “gun metal” blue aluminium box with a white top and tail. just about the size of a smartphone (3 inches by 5.5 inches), but deeper, at just under 3/4 of a inch with a nice heft to it. It comes in at 305g which to put in context is “chunky”, but an awful lot less than the weight of a standard tin of beans which typically weights 400g.

In terms of functionality, it has two USB ports (means you can charge two devices at the same time), and a single button which lights up 4 rather cool looking blue LED lights to indicate how fully charged it is (each light indicates 25%). This is a great feature, because this battery has so much power you’d not need to charge it for ages, and it’s great to see how much charge you have left.

You press the button once to see how much charge is left (it arrived with 4 lights on - fully charged), and double click the button to light up the handy white LED light which makes it a great device to take away with you on a camping trip - no more hunting around in the dark.

It comes with just a USB to micro-USB cable (so you can charge it).

4.0 out of 5 stars Excellent, solid product 18 Nov 2013
Size Name:13000mAh Black
This is a hefty external battery in more ways than one. Firstly, it is quite large (about the size of an iPhone but considerably thicker) and reasonably heavy. This gives the feeling of being a robust and substantial product. It has a pleasant feel to it and can be held in one hand.

The second way in which it is hefty is in the amount of charge it holds. I was given a free product in exchange for a review and so I spent a week using the battery as the sole way in which to charge my electronic devices just to see how long it lasted. A week later, I had used it to charge my phone, Kindle, iPod and a bluetooth speaker on more than one occasion and had still only used 25% of the charge. This is very impressive, especially as it can charge two items at the same time (one slot is specifically for items such as tablets but you can recharge smaller devices in it as well) - larger items use more power but you should still get quite a few recharges from this product. The battery also doubles as a very effective small torch which will last a very long time but which is probably a bit unwieldy to hold for considerable periods because of the weight and the size of the battery (people with strong, large hands will be fine).

I can see that this would be a very useful product if you were travelling a lot or camping for a period. It could also be used where you have a number of people who might need to recharge devices over a day or so and who could share it. It is not light enough really to carry around in a bag just in case you needed it but it would fit easily into the glove compartment of a car or a suitcase.

The amount of charge remaining in the battery is shown by four blue lights which reduce in number as it empties.

5.0 out of 5 stars Super Quality 27 Nov 2013
Size Name:13000mAh White
EC Technology gave me this product free to test and keep so that I can give my honest feedback.

I have had a number of battery backup products to review recently and I have rated most of them as 5 star products. This item is definitely a 5 star product. It has a real quality feel to it and is made from a rubberised type of plastic. It also has a very bright LED torch added to the unit which is very useful at night. For those who are not aware of what this product does, it is in essence a rechargeable battery powerpack that charges other items, such as my Android phone, sat nav, tablet PC, PSP etc. The product is quite small and relatively lightweight given the capacity of its enormous charge. The layout is very simple, on the front are 4 LED lights that indicate how much charge is left so as to charge other items, a on/off button, on the top of the unit are two USB slots and the LED torch light. To use you simply charge the unit using a USB port and then use the included cables to charge the item you want to charge such as a phone. On my test, I charged my Sony Xperia phone from empty to 100% charge in 1 hour 10 minutes, so equating to almost the same charge rate as plugging it into a socket. This charge also hardly dissipated the internal battery of the unit. I think the units' battery once fully charged, will allow 8 full charges of my mobile phone, giving the unit an enormous capacity.

Unlike other battery powerpack units I have tested, this comes with 2 USB slots, which allows for dual charging of a phone and a tablet PC at the same time. It also has a very useful automatic power off which kicks in when the battery you are charging is full or after being disconnected for one minute from the charged item.
