System Notes & Configuration
System Architecture
Keys are universally the first casualty of an absent mind[cite: 7]. Tying long, messy cords to your pockets invites friction, while leaving cables in bags ensures you never have them when battery panic strikes[cite: 5].
The car key module solves this by looping the ultra-short VAFOTON 240W PD 3.1 Cable (21cm) double on itself directly through the keyring[cite: 7].
- Form Factor: Bends in half to form a clean, durable fob loop[cite: 7].
- Output: Supports up to 240W Power Delivery (E-Marker chipped), handling high-draw laptops, tablets, or phones without bottlenecking.
- Cognitive Purpose: Eliminates the mental tax of untangling loose wires while keeping emergency power physically attached to the vehicle ignition[cite: 7].
