Portable Power Stations: What They Are and Which Size You Need

A portable power station is a battery, an inverter and a set of outlets in one box. You charge it from the wall, a car socket or solar panels, then run 120 V appliances, USB devices and 12 V gear from it. This page explains the size classes and compares six models we cover in depth.

What is a portable power station used for?

It replaces a noisy gas generator for camping, RV trips, job sites and power outages. Because nothing burns, you can use it indoors and at night. The trade-off is finite energy: once the battery is empty, you need a wall socket, a car or the sun to refill it.

Every station in our US catalog that declares its chemistry uses LiFePO4 (lithium iron phosphate) cells. That chemistry trades some weight for a long cycle life and good thermal stability; our LiFePO4 vs NMC guide explains the difference.

Which size do I need?

Pick by watt-hours (how long) first, then check watts (how much at once). Runtime is roughly capacity × 0.85 ÷ load, where 0.85 covers typical inverter losses.

Size class	Example from our catalog	45 W fridge	60 W CPAP	Typical use
About 300 Wh	Anker SOLIX C300X DC (288 Wh)	288 × 0.85 ÷ 45 ≈ 5.4 h	288 × 0.85 ÷ 60 ≈ 4.1 h	Phones, lights, a DC fridge for an afternoon
About 700 Wh	Grecell H1200 (672 Wh)	≈ 12.7 h	≈ 9.5 h	Weekend camping, a night of CPAP
About 1 kWh	EcoFlow DELTA 3 (1,024 Wh)	≈ 19.3 h	≈ 14.5 h	Camping trips, short outages
About 2 kWh	Jackery Explorer 2000 v2 (2,042 Wh)	≈ 38.6 h	≈ 28.9 h	RV trips, fridge through an outage
3 kWh and up	Anker SOLIX F3000 (3,072 Wh)	≈ 58 h	≈ 43.5 h	Home backup, power tools, several days off-grid

Be aware that our US catalog is thin on small, light AC stations. The only unit near 300 Wh with a published weight is the C300X DC, and it has no AC outlets. If you need something under 5 kg (11 lb), you will have to compromise on capacity or AC output.

How do the main models compare?

These six stations cover the useful range from compact to whole-home. Every figure comes from the Amazon listing; an empty cell means the manufacturer does not publish it there.

Two numbers stand out. The Jackery Explorer 2000 v2 packs 2,042 Wh into 17.9 kg (39.5 lb), about 114 Wh/kg, while the Bluetti AC200PL carries 2,304 Wh at 32.7 kg (72.1 lb), about 70 Wh/kg. That gap matters if you move the unit often.

What specs matter most?

Capacity, continuous AC output, solar input and UPS switchover time decide most purchases.

• Capacity (Wh): how long it runs. Use the formula above.
• AC output (W): the most it can power at once. A microwave or a space heater needs 1,200 W or more.
• Surge (W): short peaks for motors and compressors. Several listings do not publish it.
• Solar input (W): how fast the sun can refill it. At full input, the DELTA 3 needs 1,024 ÷ 500 ≈ 2 hours of ideal sun; real panels deliver about 70-80 percent of their rating.
• UPS (ms): how fast it takes over when the grid drops. 10-20 ms keeps most electronics running.
• Weight: anything over 20 kg (44 lb) is a two-hand or wheeled carry.
