Digital Camera World Verdict

The Belkin 20,000mAh power bank is an easy and affordable way to keep your devices topped up with power throughout the day while away from a main supply. The power bank is not the fastest charging device out there and will be no good for laptops, but its large capacity will reliably charge your phones a couple of times over and can charge up to three low-powered devices at once.
