Dubleup power bank £40

THIS IS A preview product so if you like the look of it, go to the website and check out the Kickstarter page - the first 6000 backers will get one for $50 (which is £39.94 at today’s exchange rate). It’s the thinnest, lightest charger pack I’ve seen and gave two charges of my iphone – though it didn’t charge the phone fully the second time round. It will get you out of a hole, but you need to remember to recharge it as soon as you get home. CB
