Using a Power Station in Cold Weather

By Hicham M. · Updated October 17, 2026

Lithium batteries handle cold far better when they’re giving power than when they’re taking it. All but one power station in our table below can run its outlets below freezing, and none of them is rated to charge there. That one fact shapes how you store, charge and use a station in winter.

Why charging stops at 32°F

Charging pushes lithium ions into the battery’s graphite anode. In the cold that process slows down, and the ions can pile up on the anode’s surface as metallic lithium instead of moving inside it. This is called lithium plating. A 2016 review in RSC Advances explains that the interface reactions “declined sharply below 0 °C” and lists the consequences: plated lithium permanently removes usable lithium from the cell, it can grow into needle-like dendrites that “pierce the separator and induce an internal short circuit”, and even when it isn’t dendritic it “accelerates the thermal runaway” of the cell.

So makers block it. All 24 models we checked list 32°F (0 °C) as the lowest charging temperature. Goal Zero’s Yeti 1500X manual says the Yeti “will not allow charging below freezing for safety reasons”, and Jackery’s page for the Explorer 1500 Ultra says charging “stops automatically below freezing”. This applies to LiFePO4 (LFP) and NMC alike; the anode is the problem, not the cathode chemistry.

A practical catch: the limit is about the battery’s temperature, and the manuals quote it as ambient temperature. A station that sat in a 20°F garage overnight is still cold inside after you carry it into the kitchen. Give it time to warm up before you plug it in or connect solar.

Published temperature ranges

These come from each maker’s user manual or official spec page. Fahrenheit values are converted from the Celsius figures the manuals print.

Goal Zero Yeti 1500X one operating range for both; manual says it won’t charge below freezing	NMC	32°F to 104°F	32°F to 104°F

Source for each row is listed under Sources below. The Yeti 1500X manual gives a single operating range of 32°F to 104°F rather than separate charge and discharge ranges.

The lowest discharge ratings fall into 4 groups: −4°F (11 models), 5°F (2 models), 14°F (10 models) and 32°F (1 model). The BLUETTI, Anker and Goal Zero PRO 4000 models here go to −4°F, the EcoFlow, DJI and other Jackery models stop at 14°F, and Jackery’s Explorer 1500 Ultra and 5000 Plus sit in between at 5°F, with less power available near the bottom of that range. The top of the charge range varies too: Jackery’s original Explorer 300 should only be charged up to 95°F, a summer limit worth knowing if it lives in a car.

How much capacity you lose in the cold

Cold doesn’t remove energy from the battery, but it makes it harder to get out. Internal resistance rises, voltage sags under load, and the battery management system cuts off sooner. Some of the energy comes back when the pack warms up.

How much? A 2025 study from Politecnico di Torino, published in Batteries, ran a 23 Ah LiFePO4 cell at half its rated current (0.5 C) in a climate chamber. Compared with room temperature, the cell gave about 5% less capacity at a surface temperature of 2 °C (36°F), about 15% less at −9 °C (16°F) and about 35% less at −20 °C (−4°F). At the −20 °C setting the researchers report “it was not possible to charge the battery” at all.

That is one cell from one maker at one discharge rate, so treat it as a sense of scale. A power station is also not a bare cell: the inverter and the battery itself give off heat while working, which slows how fast the pack cools.

What our simulator assumes

The simulated runtimes on our model pages include a column for a 0 °C (32°F) garage. For that column the simulator assumes LFP models keep 80–90% of their usable capacity and NMC models keep 75–88%, varied across 200 runs. For LFP that is more pessimistic than the Torino result near freezing (about 95%) and close to what it measured around 16°F. We kept the cautious figure because a station’s cutoff behavior in the cold isn’t published. We haven’t found a comparable primary measurement for NMC cells, so the NMC range is our assumption and is labeled as one.

Here’s what that means for a winter outage. Our planning figure for a gas furnace blower is 300 W on average. On a 2,048 Wh LFP station, the plain calculator gives about 5.8 hours; with the simulator’s cold range applied, that drops to about 4.6 hours to 5.2 hours. A furnace keeps the house warm, which keeps the station warm, so a station indoors next to the furnace is better off than one in an unheated garage. A space heater is a different story: running nonstop at 1,500 W it would empty the same 2,048 Wh station in about 1.2 hours, before any cold loss. Run your own numbers in the real-world runtime simulator.

Self-heating batteries

Some home-battery systems carry heaters that warm the cells before charging. EcoFlow’s page for the DELTA Pro Ultra says its battery “automatically starts self-heating if the temperature is lower than 32℉”, and lists a charging range down to −4°F. The DELTA Pro Ultra isn’t in our database. None of the manuals or spec pages we read for the 24 models above describe a battery heater, and all of them stop charging at freezing. If a maker claims cold charging, look for the charge temperature in the spec table, not just the marketing copy.

Practical advice

Store it indoors. EcoFlow’s DELTA manuals list a storage range of 14°F to 113°F with 68°F to 86°F as optimal. Jackery’s Explorer 1000 v2 manual recommends 32°F to 77°F for storage up to a year. A closet beats a garage.
Charge it warm, then take it out. Top it up indoors before a storm or a cold trip. If you must charge outside, wait until the station has warmed up; many will simply refuse to charge and show a low-temperature warning until then.
Don’t leave it flat in the cold. BLUETTI’s Elite 100 V2 manual says that if the charge drops to 0% in storage, charge it within 48 hours and keep it at 41°F to 95°F for 6 hours before charging.
Insulate, but let it breathe. Goal Zero suggests keeping a Yeti in an insulated cooler in sub-zero conditions so its own heat keeps capacity up. Stations with inverters and fans also need airflow: EcoFlow’s DELTA Pro 3 manual says not to block or restrict the heat dissipation system. Off the ground, out of the wind, and with vents clear is a sensible middle.
Watch solar voltage on cold mornings. Panel voltage rises as temperature drops. See series vs parallel wiring before you add a panel in winter.
Plan with a margin. Size for the cold with the power station finder and a 20% margin, or use the outage sizing guide.

Questions

Can I charge a power station from solar below freezing?

Not on any model in our table. They all list 32°F as the lowest charging temperature, and the battery management system blocks charging below it. The panels may be producing power, but the station won’t accept it until the battery warms up.

Is LiFePO4 better than NMC in the cold?

Neither can be charged below freezing on these models. For use in the cold, the published ranges depend more on the maker than on chemistry: the two NMC Jackery models here are rated to 14°F, the same as several LFP models. See LiFePO4 vs NMC.

Does cold damage a power station that isn’t being used?

Storage ranges are wider than charging ranges, but they still have limits, and the makers recommend room temperature for long storage. Check your model’s manual; the storage range is usually in the specifications table.
