Power station cold-weather capacity and limits
Four power stations, one table. Each row is what the makerstates about capacity, chemistry, and the temperatures it will charge and discharge in, with the maker's own wording. Where a maker does not say, the cell says so.
The short answer to “how much capacity does a power station lose in the cold?” is that none of these four makers publishes a number. What they do publish is a temperature window, and the charging window is narrower than the discharging one on every unit that states both. We copied the figures from each maker's own page on 12 November 2026; we did not test any unit, and nothing below is an estimate.
Capacity, chemistry and temperature limits, as each maker states them
| Power station | Capacity | Chemistry | Charging temperature | Discharging temperature | What the maker says about the cold |
|---|---|---|---|---|---|
| Jackery Explorer 1000 v2 | 1070 Wh (30.4Ah/35.2V DC) | LiFePO4 | 32~113 °F (0~45°C) | 14~113°F (-10~45°C) | Not stated by the maker (no capacity figure for cold on the page we read). |
| BLUETTI AC180 | 1,152Wh (the AC180P is 1,440Wh) | LiFePO₄ (Lithium Iron Phosphate) | 32℉-104℉ / 0℃-40℃ | -4°F-104°F (86°F-104°F: 1,500W Max.) -20°C-40°C (30°C-40°C: 1,500W Max.) | Maker FAQ: “You can use the AC180 to power your devices in cold weather, but please avoid recharging it below freezing.” No capacity figure for cold is given. |
| EcoFlow RIVER 2 Pro | 768Wh | LFP (the page also says LiFePO4) | 32°F to 113°F | 14°F to 113°F | Maker lists an “Optimal Operating Temperature” of 68°F to 86°F and says its BMS includes low-temperature protection. No capacity figure for cold is given. |
| Anker SOLIX C300 | 288Wh | LiFePO4 | -4°F to 104°F (one operating range, no split) | -4°F to 104°F (one operating range, no split) | The maker gives one “Operating temperature” of -4°F to 104°F and does not split charging from discharging. No capacity figure for cold is given. |
Cycle life, as the makers state it
Not a cold figure, but the makers print it beside the chemistry, and the end-of-life percentage differs by maker, so the numbers are not directly comparable.
- Jackery Explorer 1000 v2: 4000 cycles to 70%+ capacity
- BLUETTI AC180: 3,500+ Cycles to 80% Original Capacity
- EcoFlow RIVER 2 Pro: 80%+ capacity after 3000 cycles
- Anker SOLIX C300: 3000+ Cycles to 80% (Battery Lifespan to 80%)
How to read the table
A temperature limit says where the maker states the unit will operate. It does not say how much of the rated capacity is available there. Jackery's product page prints 1070 Wh in its spec table and 1024Wh in its headline; the table shows the spec-table figure. If you are sizing a unit for a cold location, put your own loads into the power station size calculator and read the maker's manual for your exact model. For the longer explanation of what cold does to a lithium battery, see do power stations work in cold weather, and for which unit suits a winter outage, the winter outage picks.
Questions this raises
How much capacity does a power station lose in the cold?
None of the four makers on this page publishes a capacity figure for cold. What they publish is a temperature window for charging and for discharging. The table gives each maker's own window, exactly as printed.
Can I charge these power stations below freezing?
On the pages we read, Jackery, BLUETTI and EcoFlow each state a charging lower limit of 32°F (0°C). BLUETTI also says to avoid recharging below freezing. Anker states a single operating range of -4°F to 104°F and does not give a separate charging limit.
Which of them can discharge at the lowest temperature?
By the makers' own stated figures: BLUETTI AC180 is listed down to -4°F (-20°C) for discharging, the Anker SOLIX C300 has an operating range down to -4°F, the Jackery Explorer 1000 v2 down to 14°F (-10°C) and the EcoFlow RIVER 2 Pro down to 14°F. A stated limit is where the maker says the unit works, not how much capacity it keeps there.
Why does the table say “not stated by the maker”?
We only print figures a maker publishes. If the page we read did not give one, we say so instead of filling the gap with an estimate. Check the maker's current page and manual for your exact model before you rely on a limit.
