Tessan Aero 5000 ultra-thin power bank now available to pre-order

Tessan has announced the Aero 5000 ultra-thin magnetic power bank for MagSafe-compatible smartphones, including the Apple iPhone. The slim power bank utilizes a pure cobalt semi-solid-state battery that has a reduced risk of fire for increased safety.

The Aero 5000 is merely 103 × 69.8 × 6.9 mm (4.06 x 2.75 x 0.27 in.) in size, helping maintain a slim profile when magnetically attached to the back of a phone. The cover is made of titanium alloy, providing high durability and scratch resistance, while the back is made of PC+ABS to allow wireless charging to occur.

Inside the SolidSafe battery, traditional liquid electrolyte is replaced with a semi-solid-state electrolyte that is less likely to ignite when punctured or damaged. This is especially important given the occurrence of lithium battery fires during flights and everyday carry.

The power bank outputs up to 15 watts during wireless charging and up to 20 watts during wired charging from its 5,000 mAh (3.85 V, 19.25 Wh) battery pack.

The Aero 5000 power bank is available for pre-order for $69 from the Tessan website, with shipments expected to begin in October 2026. Readers can browse the company's other charging options in the Tessan store on Amazon.
