BLUETTI AC70
A mid-size unit, 768 Wh, 1,000 W (1,500 surge), 22.5 lb, $359 at BLUETTI, sold out when checked Oct 11, 2026 ($0.47 per Wh). By our sizing it holds a night of CPAP, a day in an RV and a laptop and two phones, but not a day of home backup, two nights of camping or a working day in a van.
From the maker's published figures and our own calculations; we have not tested it ourselves.

Should you buy it?
Check first BLUETTI's store showed the AC70 sold out on Oct 11, 2026; check it is back before you plan around 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 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); a working day in a van (too little capacity: needs 1,674 Wh and 189 W at startup).
Choose it for room for extra batteries and a stated 20 ms UPS switchover: $27 less than the Dabbsson 1000L.
Choose the Dabbsson 1000L instead if you want the most battery for the money: $0.38 per Wh against $0.47, $27 more, 1.5 lb heavier; you give up the option of extra batteries.
About 653 Wh reaches the AC outlets after the 0.85 loss allowance (an estimate, not a measurement). At $0.47 per watt-hour, compare its cost with the charging speed and carry weight you need. It stores 34.1 Wh per pound. We list 32 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 | 14.5 | yes |
| CPAP machine (with heated humidifier) | 53 | 12.3 | yes |
| Refrigerator (full-size, ENERGY STAR, ~18 cu ft top freezer) (average draw, compressor cycling) | 41 | 15.8 | yes |
| Laptop (MacBook Air, charging) (charger rating, continuous) | 40 | 16.3 | yes |
| Wi-Fi router | 24 | 27.2 | yes |
| Starlink Mini (router built in) | 33 | 20.1 | yes |
| TV, 50-inch LED / Crystal UHD | 89 | 7.3 | yes |
| Camp LED light set (4 chainable lights) | 6 | 103.6 | 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.
