Portable power station database

Key findings

• The database covers 59 current models from 6 brands. Every spec comes from the manufacturer's official U.S. product page or manual, with a source link and check date for each model.

• The median model holds 1,264 Wh, delivers 2,000 W continuous and weighs 35.3 lb.

• 57 of the 59 use LiFePO4 (lithium iron phosphate) cells, and the median rated cycle life is 4,000 cycles.

• Energy per pound ranges from 22 to 56 Wh/lb. The Anker SOLIX S2000 carries the most energy per pound.

• 27 models publish a switchover time of 10 ms or less, and 22 can recharge fully from the wall in 70 minutes or less.

What are the specs of every current portable power station?

The table lists all 59 models with their battery chemistry, capacity, continuous and surge AC output, and maximum solar and AC charging input. It also gives weight, energy per pound, rated cycle life, UPS switchover time, maximum expanded capacity and manufacturer list price. Model names link to a full page, and each date links to the manufacturer source we checked. Select any heading to sort.

— means the manufacturer doesn't publish that figure. Cycles are the maker's rating to its stated remaining capacity, usually 70% or 80%.

How do the brands compare?

Brands differ more in lineup range than in efficiency. Most land within a few Wh per pound of each other because they use similar LiFePO4 cells. The bigger differences are how large the lineup goes, whether units expand with add-on batteries, and how fast they charge.

How heavy is a portable power station per watt-hour?

The median current model stores 38 Wh per pound of total weight, including the inverter, case and ports. At that rate a 1,000 Wh unit weighs about 26 lb and a 2,000 Wh unit about 52 lb. LiFePO4 cells are heavier per watt-hour than the NMC cells older models used, but they are rated for several times as many cycles.

Which models stand out?

• Largest capacity: EcoFlow DELTA Pro Ultra, 6,144 Wh, expandable to 30,720 Wh.
• Most energy per pound: Anker SOLIX S2000, 56 Wh/lb.
• Highest continuous output: EcoFlow DELTA Pro Ultra, 7,200 W.
• Highest rated cycle life: Anker SOLIX S2000, 6,000 cycles.

How was this data compiled?

Every figure is from the manufacturer's official U.S. product page, spec sheet or user manual, checked on the date shown for each model, and we record the exact wording of each spec in our research notes. We don't take specs from retailer listings or reviews, and we haven't tested these units ourselves.

• "Current" means sold new on the brand's U.S. store when we checked. Discontinued models are left out, so the medians describe what you can buy.
• Wh/lb is our calculation: capacity ÷ total weight. List price is the manufacturer's regular price on its U.S. store, not a sale price.
• Limits: manufacturers measure differently. Capacity is the cell rating, and usable AC energy is lower; we use 85% across the site. Cycle ratings use different end points (70% or 80% remaining) and different test conditions.
