Deal | This ultra-thin Qi2 magnetic power bank is just $27 on Amazon and you don't need Prime

The Sharge AeroMag Air Power Bank is one of the thinnest Qi2 magnetic power banks to come out recently. It goes up against rivals like the Ugreen MagFlow Air (8.6mm, curr. $59.99 at Amazon) and the Anker Nano (8.6mm, curr. $54.99 at Amazon). At just 69 × 104 × 8.7 mm, the AeroMag Air is virtually the same thickness, but it's now available for less than half the price.

A special Amazon coupon drops the black AeroMag Air from $39.90 to $26.90, while the silver version falls from $59.90 to $29.95. That makes it significantly cheaper than its direct rivals while offering essentially the same specs.

Talking of specs, the AeroMag Air packs a 5,000mAh battery and supports Qi2 magnetic wireless charging at up to 15W, which Sharge says can get an iPhone 17 Pro (Notebookcheck review) to 40% in around 30 minutes. For faster top-ups, a USB-C port bumps the charging speeds to 20W and can also be used to charge a second device.

That said, thin wireless power banks tend to get warm during extended use. Sharge says the AeroMag Air uses graphene cooling to help it stay cool, though you should still expect it to warm up a bit under heavy charging. On the upside, its anodized aluminum build gives it a sleek, premium feel, and it's compliant with China's latest battery safety regulations designed to reduce risks such as overheating and fires.
