Rated 5 out of 5 by from great charging abilities i bought this to try it out because my phone kept on running out of charge so i thought of getting it to have a backup just in case it did run out i can use it. the overall quality was good but the charging capabilities was great it charged my phone just under 30 minutes it stopped charging when the phone fully charged so it did not over charge. the charging time is good it only takes up to 3 hours to charge better then other power banks what take up to 5 hours to charge. i will recommend this product to anyone who wants a power bank because it is a great thing to have.

Rated 1 out of 5 by from Disappointing I bought this a few months ago from Maplin by St Pauls. In fact I bought 2 (one for the missus). I chose it because it was (a) small and (b) a great price. It was great when we tried it out soon after buying it. If I had reviewed it back then I would have given 5 stars. However, it does not seem to keep its charge. Whenever I try to use it (in the real world) to top-up my phone NOTHING happens. Maybe I should be charging it up every day...

Rated 1 out of 5 by from Short life Purchased to recharge Garmin cycle computer on long all day rides. First time out, having charged the previous evening, it worked ok to top up the garmins battery. However, having recharged the Ultramax once back home, i went to use it again about a week later only to find it totally flat! Having recharged and left it again as a test, it did the same again. no power when needed. Clearly, its either a faulty one or simply doesn't hold a charge for very long. Either way, not impressed with the product. At under £6 its not worth going back to Maplins for exchange/refund.

Rated 1 out of 5 by from Power bank Got this for my partner as the battery on her phone is not that good. charged the pack over night and tried to use it only to have it last 30 seconds. Not impressed with this product and would not recommend save your money and get a better one.

It is probably flat this will provide about a 50% charge to a smart phone.

Some people in the comments say Red light comes on when fully charged, some people say red light turns of when fully charged. WHICH is right? When i first bought it and charged it the red light came on. And no need for blue light as cannot be visible!
