The Belkin UltraCharge 20,000mAh Power Bank is the tenth entry in this guide. It is the only bank here that arrives with its USB-C cable attached to the body rather than loose in the box — one buyer describes the braided lead wrapping into a loop that doubles as a carry handle. Belkin quotes a 45W maximum output, a 20,000mAh cell that it says adds 114 hours of playback, three-device charging and a digital display for the remaining charge. The listing price is £49.99.

What stands out on this page is the ratings box. It shows 4.7 out of 5 from 57 ratings, while the star breakdown printed alongside it reads 5, 23 and 72. Those three figures total 100, not 57. The same listing disagrees with itself on ports, too: the spec field lists the number of ports as 2, while the bullet headed "charge 3 devices at the same time" describes a built-in USB-C cable, a USB-A port and a USB-C port with 22.5W shared output, against the 45W maximum claimed elsewhere. The capacity field reads only 20000, with no unit, and no weight is given for the pack anywhere in the advert. Everything on this page comes from the Amazon listing for this model, not from testing we have carried out.

**What is the maximum output of this power bank?**

45W, which Belkin says will fast charge smartphones and tablets and can charge a MacBook Air up to 45W.

**How much does the Belkin UltraCharge weigh?**

The listing gives no weight for this model, so there is no figure to set against the 20,000mAh claim.

The bullet claims an extra 114 hours of playback, without naming the device that figure refers to. The capacity spec field reads 20000 with no unit.

A limited warranty. The special features field also cites a £1500 Connected Equipment Warranty and Belkin SmartProtect, described as a 12-point safety system with dual-chip protection and intelligent temperature control.
