A power bank keeps your phone and other mobile devices running when there is no socket nearby. Collected in this category are pocket-sized models of around 5,000 mAh for everyday use, versatile 10,000 mAh power banks and larger packs of over 20,000 mAh for longer trips. There are also MagSafe-compatible magnetic models that attach straight to the back of an iPhone and charge wirelessly, as well as fast-charging USB-C Power Delivery power banks. The range includes products from Joyroom, Gembird and Green Cell, among others. Capacity is the place to start: as a rule of thumb, a power bank's mAh figure should be at least double the capacity of the phone's battery, so that a full charge is certain. Check the charging power and the ports too - fast charging calls for enough watts and a USB-C port - along with the size and weight of the device if you carry it in a pocket. Anyone considering wireless charging should make sure their own phone supports magnetic attachment. A model with an LCD display, in turn, shows the remaining charge at a glance.
