The same applies to the new Quick Charge 5, even though the latter can charge compatible phones to 50% within five minutes when using the right charger. It’s also compatible with USB PD, which is lucky, as Quick Charge 4 hasn’t had as much love from power bank manufacturers as the old Quick Charge 3 standard, with most standardising around USB PD. The most common is Quick Charge 4, which pushes out a maximum 21V and 4.6A for 100W of output.

The advantage is that you’ll be able to top up multiple devices, often simultaneously, and you’ll have enough charge to keep them going for a whole weekend or even longer. USB-C with Quick Charge 4 and USB-PD will be a given, making up for the fact that you’re carrying a heavier brick of a charger.

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.
