I would like to purchase an external battery so that me and my lad can watch films and play games on our tablets when we are out all day at shows as our tablets tend to be die by 1pm. Ideally something around the 13000mah size. So what are the recommended ones, looking to spend below £30 if that's possible for a good one.
I rate the Lumsing brand and have a few of them although not this particular model. I actually use these with the oldest one being in use since August 2014. Bear in mind that you'll only get 70%-80% of the rated capacity as some of it is lost in heat when charging. Edit: There's reasonably recent reviews here. I'd point out that I've had a couple of the Zendure power banks and returned them for a refund as they only delivered around 50% of their rated capacity.
