That huge capacity will refresh a phone six times or more, or top up a laptop and tablet too, and its fast USB-C output means you are not waiting around. It is bigger and heavier than the others here, as high capacity always is, but for serious trips and multi-device charging it is the reassuring choice. Check the price on Amazon

For iPhone owners, the Anker MagGo 10,000mAh is a lovely thing at £54.99.

Who Should Buy Which?
The right power bank depends on what you charge and where. For most people, the fast, high-capacity Anker Zolo 20,000mAh with its built-in cable is the best all-rounder. If you just want something cheap and pocketable for daily top-ups, the 10,000mAh version is superb value, while iPhone owners will love the magnetic MagGo. Anyone who needs to charge a laptop should choose the 100W Baseus, and for long trips or charging several devices for days, the 25,000mAh Anker is the one.

How to Choose a Power Bank
A few things decide the right power bank. Capacity, measured in mAh, is the headline: the smallest keyring banks hold just 3,000mAh to 6,000mAh, a 10,000mAh bank gives roughly two phone charges and stays pocketable, 20,000mAh gives four or five and suits a weekend, and 24,000mAh, 25,000mAh or more covers longer trips and laptops — though bigger always means heavier. Charging speed matters just as much: look at the USB-C wattage, with a common 22.5W or 30W enough for phones, 45W for tablets, and 100W or more needed to charge a laptop properly, while the very fastest banks now push 120W, 140W or even higher. Check the ports — two or more USB-C and USB-A outputs let you charge several devices at once — and whether it supports pass-through charging. Handy extras include a built-in cable so you never forget one, magnetic wireless charging for iPhones, and a display showing the remaining charge. Finally, remember airline rules limit the capacity you can take in hand luggage.
