Top critical review
Great idea, poor execution.
on 7 November 2016
Spotted this on discount so bought it on spec. Great idea and if it had more power it might be great in practice. I find if you don't use your phone i.e. overnight it can boost my battery by about 50%. If I am using it, for say browsing only the discharge is higher than the recharge rate. The fact that Duracell have provided 2 sockets for USB cables is laughable as no way it can charge 2 devices at a time.
I use it occasionally around the house when I need a few extra minutes, but I would be unhappy with it if I had paid more than a fiver.
