How we work
1. Load-tested
Every charger gets a 30-minute full-load run through a USB-C PD analyzer.

FLIR imagery during load + ambient — if it's dangerously hot we flag it and downgrade the score.
3. Cert-verified
Safety-cert claims are cross-checked against UL, FCC, CE, and USB-IF public databases.
