Introducing a new kind of power bank, built with safer battery chemistry

The lineup includes a 5,000mAh Qi2 magnetic power bank that is just 6.8mm at its thinnest.

TL;DR:

• Magnetic power banks with semi-solid-state batteries, first teased at CES 2026, are now available to purchase starting at $59.
• They use battery cells that contain far less flammable liquid electrolyte than conventional power banks, improving thermal stability and reducing fire risk.
• The lineup also includes what BMX calls the world’s thinnest 5,000mAh Qi2 magnetic power bank, just 6.8mm at its thinnest point.

Power banks haven’t evolved all that much in the last few years. Sure, we have faster, thinner and more feature-packed models now, but most still rely on the same lithium-ion batteries that have been around for ages. Now one company is betting that the next big upgrade isn’t charging speed or capacity – it’s the chemistry of the battery itself.

Singapore-based BMX announced that its SolidSafe magnetic power bank line, first announced at CES 2026, is now available to buy on its website and on Amazon US, starting at $59. This is the first truly semi-solid-state power bank to reach the consumer market.

What sets them apart?

They use semi-solid-state batteries, which is what sets them apart. Traditional lithium-ion and lithium-polymer batteries rely on liquid electrolytes to move energy between electrodes. But a semi-solid-state power bank drastically cuts down the amount of flammable liquid in the cell, which increases thermal stability and lowers the risk of overheating, swelling, or fire. That’s a huge peace of mind for anyone who’s ever felt a hot power bank in their bag.

BMX’s SolidSafe line features 5,000mAh and 10,000mAh models with Qi2 magnetic wireless charging, USBC fast charging and aluminium construction. BMX says that these power banks are stable under extreme conditions and are more resistant than traditional battery packs to physical damage and thermal stress. All the semi-solid-state power banks in the range are built with safety as the first priority.

The thinnest in the world

The company has also introduced the SolidSafe Air, a 5,000mAh magnetic power bank, which it claims is the world’s slimmest semi-solid-state power bank with Qi2. This little wonder measures only 6.8mm at its thinnest point and includes an 18.5Wh battery, titanium-reinforced body, 15W Qi2 wireless charging and 20W wired charging via USB-C. BMX is promoting it as a travel-friendly alternative for those who want the extra safety and magnetic convenience without the bulk.

Larger models have more features

But other than the battery tech, the larger SolidSafe models do have some nice extras. Includes a built-in USB-C lanyard cable, a colour display with real time charging info, and supports up to 30W USB-C charging. One variant even includes a microSD card slot for onboard storage. So you get a semi-solid-state power bank, with thoughtful design and added utility.

Bottom line:

If you’re tired of sweating over swollen batteries or overheating, this new semi-solid-state power bank lineup from BMX is worth a peek. At just $59, it’s a small price to pay for safer, more stable power on the go.
