Q & As

Rated 3.2 out of 5 by 12 reviewers.
Rated 2 out of 5 by Could be better Ive had this for a couple of months but have only just needed to use it. Charged it fully and its only given me a 12% charge - is this normal? Thought I would have gotten so much more :( 12 December 2014
Rated 4 out of 5 by iPhone 5 compatible Some reviews say this item isn't compatible with an iPhone 5, it is. Use your mains charger, remove the 3pin section and the USB will go into the juice box. I used the provided adapters to charge the box with our iMac 20 June 2014
Rated 1 out of 5 by Disappointed as no iPhone 5 connection I was really excited about purchasing this as it was just what I needed when on the go, unfortunately I am disappointed there is no cable for the iPhone 5. I should have checked but assumed there would be. I am hoping to get a refund. 12 June 2014
Rated 1 out of 5 by not compatible with Samsung note 3 Product info says compatible with Samsung Galaxy note 3 07 June 2014
Rated 2 out of 5 by Disappointed Bought this for my daughter's I phone. She has now upgraded her I phone to the 5s and there is no adapter for that phone. Really disappointing. Will take it back and try and get a refund 08 May 2014
Rated 5 out of 5 by A great gift for a man difficult to buy for. I was struggling to find something for my son's 30th birthday. He has a busy life and a job that invovles shifts with are often extended so it is not easy to keep his monile phone charged. this is perfect it can re-charge his phone up to 3 times before it needs charging again so easily support him through a block of shifts. The bright colours available mean it is easy to see in the bottom of a bag or the back of a locker and the size makes it easy to carry round. Perfect gift for any one who uses ther phone a lot and is moblie to unable to charge from a socket. 30 April 2014
Rated 5 out of 5 by great little charger Very impressed with this charger. I'm often on the long train journeys and this will come in very handy. Only slight downside is that no iphone5 attachment is included. 11 January 2014
