Our take on the Energizer Slim Metal 20W Magnetic Wireless Qi2 Power Bank

This is a slim metal power bank that snaps onto a MagSafe iPhone and charges it wirelessly at up to 15W through the Qi2 standard, with a USB-C PD port for wired charging of phones, earbuds or a second device. The aluminum body is about 0.62 inches thick, so it adds little bulk in a pocket, and an LED display shows remaining battery. It suits iPhone owners who want cable-free top-ups on the go. Against rivals like Anker's MagGo and Baseus magnetic packs, it stands out for the metal shell and the display, but its 20W total output is modest and the Qi2 coil runs warm during long charges, which owners mention often.

Questions and answers

Does it work with non-MagSafe phones?
It charges any Qi2 phone wirelessly, but the magnetic alignment only holds on MagSafe iPhones or a magnetic case. Other phones can use the USB-C port with a cable.
How fast does it charge wirelessly?
Qi2 tops out around 15W on compatible iPhones, and the pack's total output is 20W. Wired USB-C PD is faster for a quick top-up.
Can it charge two devices at once?
Yes. It has one wireless pad and one USB-C PD output, so you can charge a phone on the magnet and earbuds or a second phone by cable.
Is a cable or charger included?
No. You need your own USB-C cable and wall adapter to refill the pack or charge by wire.
How do I check the battery level?
The LED display on the body shows the remaining charge, so you don't have to guess from a row of dots.
Is it safe to leave on the phone overnight?
It has overcharge and short-circuit protection, but the pack warms up during wireless charging, so many owners take the phone off once it is full.
