for what it is worth, I received an email promotion last week for this kickstarter project:
BattPack is an ultra-streamlined 10,000mAh power bank designed to eliminate cable dependency through functional surface integration. Operating at up to 22.5W, its unique architecture allocates both top and bottom planes as active magnetic charging interfaces. This dual-sided design allows you to simultaneously power a smartphone and wireless accessories without carrying a single cable.
-
10,000mAh & 22.5W Output: Delivers a robust portable power reserve with high-speed 22.5W charging capabilities.
-
Dual-Sided Wireless: Features two independent magnetic charging planes to power multiple devices (e.g., iPhone and AirPods) at the same time.
-
Zero-Cable Architecture: Intuitively magnetized, modular form factor reallocates surface area to eliminate everyday carry bulk.
