What is a power bank?
A power bank is a device with an internal battery that will keep your portable devices charged while you are on the move. You can use it to charge smartphones, MP3 players, tablets and other devices. It is charged up through USB power and is compact in design, allowing you to carry the power bank around with you. The LED indicator lights allow you to see the charge status of any attached device, and also show how much juice is left in the power bank.

How does it connect to my device?
The power bank has two built-in USB sockets so you can connect a range of devices, including smartphones, tablets, MP3 players and dash cams directly for charging. Simply connect a suitable USB cable from the power bank directly to your smartphone. Many devices are supplied with their own USB cable, allowing you to recharge without an additional cable being required. Spare or additional USB cables for many devices are easy to purchase, as many are universally compatible with devices. Thanks to the smart power sensor inside this powerbank, it will also switch off once your device is fully charged to prevent it from damaging the battery.

Is it rechargeable?
The power bank has a built-in lithium-ion battery which takes 11 hours to recharge to full capacity, using a 2A power supply. The power bank has a micro USB cable included, allowing you to connect the power bank to a mains USB plug and recharge the power bank to full capacity.

Rated 5 out of 5 by from Really Useful Product This is a really handy bit of kit to have, especially for long journeys. I've had problem with the cigarette lighter in my car, so I needed something to power a sat nav and to keep my phone charged and this unit did the job really well. It held a good charge so I had no problem recharging my phone a number of times, and keeping the sat nav going for hours while trekking across Europe. Great product...

Rated 5 out of 5 by from Great capacity! Took a really long time to charge up however one power pack lasted two of us for the duration of Glastonbury (5 days). We didn't drain the iphones below 45% so wasn't a full recharge but thought it was still pretty good going.

Rated 5 out of 5 by from Great Product Bought this for my son who was on a 4 day festival. Kept his I phone going with loads to spare. And we now use it routinely at home in stead of using sockets.

Rated 1 out of 5 by from failed to charge properly after a few months bought this a few months ago and at the time it worked perfectly . then suddenly it wont charge. it will charge the first bar and the second blinks but it wont go any further even after 2 days on charge. obviously a fault with the product. i pad in cash some months ago and no longer have the box either so i dont think ill have luck taking it back, But its a shame as it seemed really good . but wont pay £50 for a power bank that only lasts a few months!!

Rated 2 out of 5 by from Beware - takes days to recharge not hours This seemed great value but even using a 2 amp charger supplied by Maplin these batteries take days to recharge. Don't use if you need a fast recharge time

Is there anyway you can keep the power bank powered on - looking to power a GoPro (using a battery eliminator) in a camera trap
