Aferiy P300
A large unit, 2,048 Wh, 3,000 W, 47.6 lb, $719 $1,099 at Aferiy, checked Oct 11, 2026 ($0.35 per Wh). By our sizing it holds a night of CPAP, a day in an RV, a working day in a van and a laptop and two phones, but not a day of home backup or two nights of camping.
From the maker's published figures and our own calculations; we have not tested it ourselves.

Should you buy it?
Buy it for: a night of CPAP (a CPAP with its humidifier for one 8-hour night); 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).
Not for: a day of home backup (too little capacity: needs 2,323 Wh and 1,351 W at startup); two nights of camping (too little capacity: needs 2,066 Wh and 157 W at startup).
Choose it for a 7-year warranty against 5 and a 15.7 lb lighter carry: $180 less than the Pecron F3000LFP.
Choose the Pecron F3000LFP instead if you want the most battery for the money: $0.29 per Wh against $0.35, $180 more, 15.7 lb heavier; you give up warranty years (5 against 7).
Not published The maker publishes no surge figure, so motor and compressor starts rest on its continuous rating.
About 1,741 Wh reaches the AC outlets after the 0.85 loss allowance (an estimate, not a measurement). At $0.35 per watt-hour, compare its cost with the charging speed and carry weight you need. It stores 43 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 | 38.7 | yes |
| CPAP machine (with heated humidifier) | 53 | 32.8 | yes |
| Refrigerator (full-size, ENERGY STAR, ~18 cu ft top freezer) (average draw, compressor cycling) | 41 | 42.2 | yes |
| Laptop (MacBook Air, charging) (charger rating, continuous) | 40 | 43.5 | yes |
| Wi-Fi router | 24 | 72.5 | yes |
| Starlink Mini (router built in) | 33 | 53.6 | yes |
| TV, 50-inch LED / Crystal UHD | 89 | 19.6 | yes |
| Camp LED light set (4 chainable lights) | 6 | 276.3 | 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.
