Portable Power Stations for Space Heaters

Aug 12, 2025

When winter bites and your toes turn into ice pops, a Portable Power Station is your heater’s best friend. Short answer? Bluetti AC200P—big power, long runtime. But stick around—there’s more than one cosy contender, and the right choice might just save your frozen bacon.

Best Overall for Emergency Heating: Bluetti AC200P

Why it’s the top choice for high-wattage appliances

The Bluetti AC200P offers a 2000W AC output, making it ideal for demanding space heaters.
Its high continuous output means you can run most heater types without worrying about overload.

Continuous output and surge capacity for space heaters

With a powerful inverter and strong surge handling, it can easily manage the initial power spike many heaters require.
This makes it reliable for emergency heating during sudden power cuts.

Key features: capacity, fast charging, and UPS functionality

Capacity: Large battery for extended runtime.
Fast charging: Multiple input methods, including solar.
UPS mode: Keeps devices powered during grid interruptions.

Best for Long-Term Use and Expandable Capacity: Goal Zero Yeti 1500X

How to power a space heater for hours or days

The Goal Zero Yeti 1500X delivers a high-capacity battery and 1500W output, giving you longer heat during outages.

Expandable battery options for extended warmth during outages

Its modular design allows battery expansion, letting you keep the heat going for extended off-grid stays.

Sizing recommendations for off-grid heating

For a 1500W heater, the base model gives around an hour of runtime.
Add expansion batteries for multi-hour or even multi-day use.

Can a Portable Power Station Actually Run a Space Heater?

The challenge of high power consumption (750W–1500W)

Space heaters are power-hungry, often drawing 750W–1500W.
Not every portable power station can keep up.

What to look for: high continuous wattage and large capacity (Wh)

Choose a model with a high continuous watt rating and enough battery capacity to run your heater for the length of time you need.

Calculating your potential runtime (with examples)

A 1500W heater on a 1500Wh station will run for roughly one hour.
A 3000Wh station doubles that.
Always check your heater’s label or manufacturer specifications for accurate figures.

The Most Important Specifications for Your Heater

Understanding Wattage, Watt-Hours, and Surge Power

Wattage determines how much power your heater draws.
Watt-hours measure stored energy.
Surge power handles the short burst when the heater starts up.

Why a pure sine wave inverter is non-negotiable

A pure sine wave inverter ensures your heater runs smoothly and safely, without risking damage to sensitive electronics.

Safety features to protect your devices and home

Look for overheat protection, short-circuit prevention, and battery management systems for extra peace of mind.

Alternatives to Consider for Portable Heating

Why an electric blanket or low-wattage heater might be a better fit

If you only need to heat yourself rather than the entire room, a low-wattage device uses far less power.
This extends battery life considerably.

When a diesel or propane heater is the more practical choice

For very long runtimes or extremely cold weather, fuel-based heaters can be a more efficient option.

Portable power station vs. gas generator for heating

Portable power stations are cleaner, quieter, and safer to use indoors.
Gas generators can offer more power but require ventilation and fuel storage.
