It charges a smartphone the equivalent of 1.5 times, and easily slips into your pocket, briefcase or handbag.
Like the Juice Power Station, the Belkin 5k wins points for aesthetics; but rather than a Day-Glo, easy-to-spot festival look, its sleek and muted and comes in a silvery light grey (£24.99, very.co.uk), rose gold (aka millennial pink –£19, Amazon) or black (£17.99, carphonewarehouse.co.uk). It screams: “I’m organised. Look how efficient I am, with this slimline accessory, which means I will never, ever miss an urgent work email!”
It takes around three hours to charge from empty (considerably less time than the Juice Power Station), and once charged, Belkin says its tests show that charge will not diminish by more than 50pc even after a year’s time left dormant – all very impressive, and useful.
It looks metallic, but the case is actually made of plastic polycarbonate, which houses the lightweight lithium-ion polymer battery cells that power it. Again, it has two USB ports, one that has a 2.4A amperage, and one 2A, and four LED indicators that show the battery level.
As well as a 2-year limited warranty on the power bank itself, Belkin also offers a connected equipment warranty, which is reassuring: it means that if your device is damaged by an electrical charge while properly connected to the portable charger, Belkin will repair or replace it up to a value of £1,500.
