Numeric LEDs give precise percentage readouts but require more space, circuitry, and visual brightness to remain legible outdoors. Five-segment LED bars are simpler, faster to read, and more durable, but they trade accuracy for a coarse 20% step view of remaining charge. We’re testing both to see which aligns better with real-world use, pocketability, and the overall design of the ecosystem. view post

Testing various weight to strength ratios with this particular component at N52 magnetic strength, which is extremely strong.  Qi2 uses magnetic coils that vibrate at specific frequencies (87-205 kHz) to wirelessly transfer up to 15W of power—think of it like two guitar strings that resonate together. The magnetic ring's job is to perfectly line up these coils, which older Qi chargers struggled with, boosting efficiency from around 60% to over 75%. The system constantly monitors itself through feedback loops to optimize power transfer and... view post

Watch and Airpods do attach by magnets but the small magnet (you can see if in the middle of the copper coils) is not strong enough to hold either device in any active environment. Not ideal for on the go charging. So we're going to skip this in V1. view post

Packs built from mixed or rewrapped cells suffer from cell imbalance, elevated internal resistance, and a higher likelihood of thermal runaway under load. This is exactly why we refuse to use non-solid, non-traceable cells. Our power systems are built around semi-solid-state batteries: matched, grade-A cells with tighter electrolyte containment, higher thermal stability, and fully documented provenance. Reliability starts at the chemistry level, and we only build on platforms engineered for safety and consistency. view post
