Summary

Glass Briefcase, prorated five-year cover

What it is: a 100 W, 12 V folding glass panel with kickstands and a handle, for power stations, campers and 12 V batteries
The trade-off: above-typical efficiency for a folding panel and an output guarantee, but heavy glass, prorated workmanship cover and a weak heat rating
Availability: backordered on richsolar.com on 2026-10-14
Look elsewhere for: a light fabric panel or power-station adapters in the box

Strengths
