ALLPOWERS R1500: what it runs in an outage
On paper the R1500 is the strongest 1kWh-class station we cover: as much battery as the AC180, a higher surge rating, the most solar input in its class and real expansion. The questions are the brand and the name.
Good fit if you…
- want the strongest spec sheet in the 1kWh class — surge, solar and expansion
- plan to use solar (650W max)
- want room to grow — up to three B1000 batteries
Look elsewhere if you…
- are looking at the R1500 LITE — a different, smaller model (1,056Wh, 1,600W)
- need to carry it often (36.8 lb — among the heaviest in its class)
Estimated runtimes
These come from the same calculation as the planner: our representative appliance figures, efficiency estimated from the load, and a 10% battery reserve. The range runs from our cautious to our optimistic estimate; verdicts use the expected value in between. Your appliances will differ — try your own.
| Load | Runtime | Verdict |
|---|---|---|
| Wi-Fi, lights and phones, 8 hours | about 11–15 h | Covers it |
| Fridge alone, 12 hours | about 11–15 h | Only just |
| Fridge, Wi-Fi and lights, 12 hours | about 6.9–8.3 h | Short — expansion battery fixes it |
| CPAP with heated humidifier, one night (8 hours) | about 15–21 h | Covers it (estimate — test first) |
| Work-from-home day: Wi-Fi, lights, phone, laptop (8 hours) | about 7.7–9.3 h | Only just |
| CPAP plus fridge, overnight (8 hours) | about 7.5–9.0 h | Only just (estimate — test first) |
What the numbers mean for you
Start with the name: the “1500” in R1500 is its maximum AC charging input, not its output. It delivers 1,800W continuous with a 3,000W surge.
On our estimate it runs a typical fridge for about 13 hours and Wi-Fi, lights and phones for about 14. With B1000 batteries it grows to 4,608Wh — the total ALLPOWERS states on its US product page for up to three B1000s at 1,152Wh each — enough for a fridge, Wi-Fi and lights through a full day and more.
Against the BLUETTI AC180 (same battery, same output): the R1500 has a higher surge rating, more solar and expansion; the AC180 is slightly lighter.
Limitations and things to check
- Not the R1500 LITE (1,056Wh, 1,600W) — check the exact model before buying.
- ALLPOWERS’ own documents have disagreed about this model — a 2026 lineup guide called it not expandable, and warranty figures have varied between documents. Its US product page (checked October 12, 2026) states expandable to 4,608Wh with three B1000 batteries and a 5-year warranty; those are the figures we use.
- Its cycle claim (3,500+) gives no end-of-life percentage, so it can’t be compared with other brands.
- Some figures come from ALLPOWERS’ EU site and a manual hosted by a third party, because the US page shows fewer specs.

Sources: ALLPOWERS US product page (checked 2026-10-12): 1,152Wh, 1,800W continuous, 3,000W surge, 650W solar, 1,500W AC charging, 36.8 lb, expandable with three B1000 batteries to a stated 4,608Wh total, 5-year warranty. Other ALLPOWERS documents have described expansion and warranty differently; the US product page governs here and the conflict is disclosed on the product page. Not the R1500 LITE (1,056Wh, 1,600W).

Alternatives worth comparing
- BLUETTI AC180 — same battery and output, lower surge, no expansion, 1.5 lb lighter.
- EcoFlow DELTA 2 — less battery but 10 lb lighter, also expandable.
- BLUETTI AC200L — the 2kWh step up if you’d rather not add batteries.
