iWALK 10,000mAh Qi2 15W Magnetic Power Bank

The iWALK MXB010 is the cheapest magnetic power bank in this guide at £19.99, and it sits at number 8. On the measure this article keeps coming back to — wireless watts — it is one of the more straightforward entries: the title and the bullet points declare Qi2 Certified 15W, the same figure the £29.98 UGREEN Zapix claims and more than the 7.5W listed for the £24.99 Anker Zolo. Its capacity field is also one of the few here that reads properly: "Battery Capacity: 10000 Milliamp Hours", against the "10" on the Anker MagGo and the "10000 Amp Hours" on the Anker Zolo.

The rest of the iWALK spec sheet is not tidy. It gives the power source as "Corded Electric" on a product whose main selling point is wireless charging, gives the voltage as 20 Volts alongside a 30W fast-charging claim, and lists the wireless standard as "MagSafe, Qi" while the title says Qi2 Certified — the spec field never repeats the 15W number. Item weight is 215 g against a battery weight of 68 g, and the declared charge time is 2 hours. With 417 Amazon ratings at 4.2 out of 5, it is also one of the better-reviewed models in the guide. Everything on this page comes from the Amazon listing, not from testing of our own.
