Spend £18 to £30 and you’re looking at power banks with a 10,000-20,000mAh capacity and better connectivity, with USB-C connections now pretty much standard. At the upper end of this range, though, you’ll have sufficient capacity to recharge your phone or give a tablet a decent boost – and you can find one the size of a smartphone or a Mars Bar for around £12 to £18. These days we’d avoid anything below 5,000mAh, as it won’t have enough charge to refuel most recent smartphones. The cheapest and smallest power banks will have a capacity of between 2,500mAh and 10,000mAh.
The rules are simple enough: the less you spend, the lower the capacity and the slower the power bank will charge.
