TESSAN AERO 5000: 6.9mm titanium MagSafe battery with semi-solid-state core

A new MagSafe battery has hit the market with a design that stands out for its construction rather than capacity. The TESSAN AERO 5000 features a 6.9mm-thick body — roughly the thickness of three stacked credit cards — and a back panel made from the same titanium alloy used in iPhones. According to the manufacturer, the device should feel like a MagSafe wallet in your pocket, not a bulky external power pack.

The key feature is the SolidSafe cell, built on pure cobalt with a semi-solid-state structure. Unlike traditional lithium-ion batteries that contain highly flammable liquids, this design is claimed to drastically reduce heat buildup and prevent thermal runaway even under severe physical damage. That matters because overheating remains the biggest enemy of battery longevity.

In terms of specs, the AERO 5000 delivers up to 15W wirelessly and up to 20W through its USB-C port. Reviewers note that having a wired output is useful even for a compact device — for example, charging AirPods. Overall, the model is positioned for users who want to minimize everyday carry weight, combining a titanium finish with modern safety standards.

Experts who have already reviewed the specifications call the AERO 5000 one of the most interesting MagSafe batteries this year. However, exact availability dates and retail pricing have not yet been announced.
