Should you buy it?
Buy it for: a day of home backup (a full-size refrigerator, a router, phones and lights for a day); a night of CPAP (a CPAP with its humidifier for one 8-hour night); two nights of camping (camp lights, phones, a laptop and a fan for two nights); a day in an RV (a day of RV lights, TV, phones and a laptop); a working day in a van (a working day of laptop, Starlink, lights and a fan); a laptop and two phones (a laptop for six hours and two phone charges).
Choose it for a 5.1 lb lighter carry: about the same price as the Pecron F3000LFP.
Choose the Pecron F3000LFP instead if you want the most battery for the money: $0.29 per Wh against $0.39, 5.1 lb heavier.
Not published The maker publishes no UPS switchover time, so it is not a confirmed uninterrupted supply.
About 1,981 Wh reaches the AC outlets after the 0.85 loss allowance (an estimate, not a measurement). At $0.39 per watt-hour, compare its cost with the charging speed and carry weight you need. It stores 40 Wh per pound. We list 36 other models in its size class; the four nearest in capacity are compared below.
What it runs, and for how long
Hours = capacity × 0.85 ÷ device watts, with the draws from the device table.
| Device | Draw W | Hours | Output and surge cover it? |
|---|---|---|---|
| CPAP machine (no heated humidifier) | 45 | 44 | yes |
| CPAP machine (with heated humidifier) | 53 | 37.4 | yes |
| Refrigerator (full-size, ENERGY STAR, ~18 cu ft top freezer) (average draw, compressor cycling) | 41 | 48 | yes |
| Laptop (MacBook Air, charging) (charger rating, continuous) | 40 | 49.5 | yes |
| Wi-Fi router | 24 | 82.5 | yes |
| Starlink Mini (router built in) | 33 | 60.9 | yes |
| TV, 50-inch LED / Crystal UHD | 89 | 22.3 | yes |
| Camp LED light set (4 chainable lights) | 6 | 314.4 | yes |
"Yes" means its continuous output covers the draw and its surge rating covers the startup figure we use, by arithmetic on ratings, not a test. Startup figures: the CPAP with its humidifier, 104 W at startup, from ResMed's peak figure; the refrigerator, 1,300 W startup allowance, from a larger 27 cu ft Whirlpool's tech sheet. Your own appliance's label or manual has its own.
