Can You Leave a Power Station in a Cold Car or Truck?

Short answer: you can usually store a power station in a cold vehicle, but don’t expect to use or charge it there in a prairie winter. Units that publish their limits often stop running somewhere below freezing — Jackery rates the Explorer 1000 v2 to −10°C — and most lithium batteries won’t accept a charge below 0°C. A truck cab on a January night in Alberta can blow past both.

Three different limits

Every power station has three temperature ranges, and they’re not the same:

1. Storage — how cold or hot it can sit, switched off, without harm. Usually the widest range. Look for it in the user manual.
2. Operating (discharging) — the range in which it will power your devices. Below the minimum, it shuts itself off.
3. Charging — the range in which it will refill. This is the narrowest, and it almost always starts at or near 0°C.

As an example, Jackery publishes an operating range of −10°C to 45°C and a charging range of 0°C to 45°C for the Explorer 1000 v2. Many brands don’t publish these numbers on their product pages at all — we track the ones that do in our cold-weather spec database.

What a cold vehicle actually does to it

Once the engine’s off, a parked car or truck cools to roughly the outdoor temperature within hours. So a power station left in the cab overnight will be about as cold as the night was.

• It may not turn on in the morning if it’s below its operating minimum. Warm it up first.
• It will run for less time even above the minimum, because cold batteries deliver less energy. Our runtime calculator lets you compare indoor and cold-vehicle runtimes.
• It won’t charge from the 12V outlet, solar panels or a wall plug until the battery warms above its charging minimum. That’s deliberate — charging frozen lithium cells damages them.

How to keep one usable on winter trips

• Bring it inside at night — into the house, cabin, heated tent or motel room.
• Charge while you drive, once the cab has warmed up, rather than first thing on a frozen morning.
• Insulate it. An insulated cooler or bag slows cooling on shorter stops. Take it out of the insulation while it’s running so the vents stay clear.
• Store it partly charged if it’ll sit for a while, as many manufacturers recommend — check your manual.
• Mind the summer too. A car in the sun gets far hotter than the air outside, and batteries have upper limits as well. Keep it off the dashboard and out of direct sun.

The bottom line

A power station can ride along in your vehicle all winter, but treat the cab like a freezer: fine for storage, bad for using or charging. If you need power in a cold vehicle or truck camper, choose a model that publishes a low operating temperature, or look at batteries with built-in heaters designed for low-temperature charging.
