In the box you get a lead and set of interchangeable plugs, a storage pouch and the power bank.
LEAD & PLUGS - The lead has a standard USB plug on one end and a socket on the other that will take one of the plugs. The plugs are a range of plugs to fit an iPhone 4s and below, iPhone 5 and above, microUSB to fit a range of android devices and a USB-a that fits some of the older phones and Navigation devices. If you attach the microUSB plug, then the lead becomes the charging cable for the power bank. The problem with iPhones is that they can be a bit fussy over the type of cable you use. The supplied plug was a little stiff to get in, but worked fine on my 4s. As did the other plugs on an HTC Desire, Kindle Touch and it powered up an external 2.5" drive. I couldn't test the iPhone 5 plug as I don't have one. The plugs are really incidental and a convenience, I still use my original cables where I can and there is nothing to stop you using your own USB charging cable.
POUCH - The storage pouch was a nice touch, soft on the outside, soft on the inside. There is enough room to take the power bank an the supplied lead and plugs and you could probably squeeze another lead in if you needed to.
POWER BANK - This power bank is solid block of highly polished plastic. It is completely sealed and the bonds are tight, so there is no danger of it breaking apart. on the side is a power button to turn the unit on and off, although it will power down if there is nothing attached and automatically power up when a device is attached for charging. A double tap of the power button will switch on an LED torch on the opposite edge. A nice little edition and there is a modest amount of light for a single LED. There is an LCD panel that is clear and easy to read. You are informed of how much % charge is left, which port is currently occupied (like you need to be told!) and if the unit is receiving a charge (flashes "IN"). The LCD panel will light up temporarily on a quick push of the power button or when a lead that effects the charge is plugged in or removed.
Well this is all well and good, but how well does it perform?
The Amazon item indicates that the battery is x times bigger than this phone or that phone, but that doesn't necessarily mean it will will last that many times more. That being said, from a full charge I was able to charge my iPhone 5 times (each time the phone was around 25% capacity, with one top-up at 80%), I charged up a TomTom Go720 from almost flat, a Kindle Touch from about 60% capacity and I was still left with 15%, which is probably enough to charge the iPhone again. Of course this will vary depending upon the device, condition of the battery being charged, ambient temperature and starting capacity.
The 2 USB ports enable 2 devices to be charged at the same time, but one port is more powerful than the other (1.0A and 2.1A). All of my devices charged off either port including the fussy iPhone. I can only conclude that the more powerful port will give a faster charge time, but I didn't manage to run a comparative test on this. I would guess that larger devices would need the more powerful port.
To charge the unit up, you can plug it into any standard USB port even low power ports as it only requires 1.0A. Charge time can vary, I used a mains powered 5v 1.0A port. I started mine when it was at 1% when I went to bed and in the morning (8 Hours) it was at 100%. I would guess if you have a fast charge port, it will be done in a lot less time.
If I was forced to find some negatives I would be struggling, but I would go with:
The USB ports are marked to show which is 1.0A and 2.1A, but it is difficult to read. That being said, the LCD panel will tell you which port is active when you plug in a device.
The high polished surface shows up every finger print and smudge.
This is a good piece of kit and would be ideal when out camping and away from power. Trekking and heavily using your phone with a danger of it running flat. When you want reassurance that you have a back up battery with you
The important question for the potential buyer is
Does it work?
Does it work well?
The answer to both is yes.
It really does work effectively.
I was impressed by the quality and build but the box has the usual spelling mistakes that quite a few of these Chinese produced products have.
The instructions are similar with a few causing me to smile.
Reading them you get the hang of what they are driving at and you can soon figure out how and why things work.
I soon worked that while charging a red led glows, when fully charged it turns green and when used to power up my phone it turns blue.
The big USB is the output the smaller the device.
It was really quick to charge up and kept its charge for ages.
I passe my set on to my son after I had used it for a real workout.
He is 17 and techno savvy.
So far he has managed to recharge his phone around 5 times without recharging the unit- impressive? Well his friends were.
It survived a 6th Formers school bag for over a week!
And he loaned it out (at no charge to his mates!!)
I imagine this would be fabulous for Glastonbury or any other festivals!
This really is an excellent backup when you need to recharge your device and are away from a suitable source.
Just be prepared to work out what the instructions are up to!
