Apple’s iPhone Duo requires a new kind of power strategy, and BMX is answering with a accessory that prioritizes safety over raw capacity. The SolidSafe Ultra MagSafe power bank targets users who need reliable charging without the anxiety of standard lithium-ion swelling or overheating. This shift matters because the Duo’s form factor demands a compact, durable solution that fits seamlessly into daily carry.
BMX launches a 5,000 mAh MagSafe power bank with semi-solid battery chemistry for $79.99
BMX built the SolidSafe Ultra around a 5,000 mAh semi-solid lithium-ion battery to mitigate thermal risks. The cell chemistry offers a safer alternative to traditional liquid electrolytes, which is a critical feature for a device meant to attach directly to a phone. The unit sits in a black aluminum case that measures 77 x 88 x 11 mm, keeping the profile slim enough for pocket storage.
Specifications
- Battery Capacity: 5,000 mAh
- Battery Chemistry: Semi-solid lithium-ion
- Dimensions: 77 x 88 x 11 mm
- Wired Charging Output: Up to 20W (USB-C)
- Wireless Charging Output: Up to 15W (MagSafe)
Charging capabilities include a built-in USB-C cable that delivers up to 20 watts of wired power. A magnetic charging pad on the back provides up to 15 watts for wireless MagSafe connections. When users activate both outputs simultaneously, the power bank splits the load to 10 watts through the USB-C cable and 5 watts through the magnetic pad. Recharging the power bank itself supports up to 15 watts of input power.
A color LCD display sits in the center of the 360-degree ring kickstand to show real-time charge levels and output wattage. This visual feedback helps users monitor power distribution without guessing the status of their devices. The aluminum housing adds durability while maintaining a compact footprint for travel.
The SolidSafe Ultra MagSafe is available for $79.99 from BMX and Amazon. This price point positions the accessory as a premium safety-focused option for iPhone Duo owners who value thermal stability and dual-output flexibility in a single compact unit.
