About QuietWatt

Updated 3 Nov 2026. QuietWatt is an independent directory of portable power stations, run by BLAZE. We compare capacity (Wh), output (W), surge, weight and noise so you can pick the right size for a fridge, CPAP, blackout or camping trip.

How we compare

• Specs come from manufacturers' own product pages and manuals.
• Runtime figures are estimates from published capacity and typical loads. Real results vary with temperature, battery age and inverter efficiency.
• We haven't lab-tested these units. We don't claim hands-on tests we haven't done.
