How to choose a portable power station

Start with watt-hours (Wh), not watts. Wh is how much energy the unit stores (how long it runs your gear); watts is how much it can deliver at once (whether it can start a given appliance). A 1000Wh unit runs a 100W fridge for roughly 8 to 9 real-world hours. Match Wh to how long you need to run things, and check the AC output wattage is high enough for your biggest appliance.

LiFePO4 (LFP) is worth paying for. The newer EcoFlow, Bluetti and Anker units use LiFePO4 cells rated for 3000 to 6500 charge cycles, so they last many years and survive used ownership well. Older Jackery and Goal Zero models use NMC cells rated for around 500 cycles, which is fine for occasional use but fades faster. If you will cycle it often, prioritise a LiFePO4 model even at a higher $/Wh.

Think about recharge speed and expandability. Look at how fast it recharges from the wall (newer units hit 80% in under an hour) and whether it takes solar input if you want off-grid backup. Some lines (EcoFlow Delta, Bluetti) accept add-on battery packs to grow capacity later, which can be cheaper per Wh than buying one huge unit up front.

New, open-box or used. Manufacturer-refurbished and open-box units (often sold on eBay by the brands themselves) come with some warranty at a real discount; private used sales are cheaper still. Whichever you choose, sort by $/Wh above to see which model genuinely gives the most stored energy for the money right now.

Cheapest by model, at a glance

A daily snapshot of the lowest genuine eBay price for every model we track, and how good that price is right now versus its usual level, updated automatically. Prices last refreshed 30 August 2026 . Tap a price to see that model's cheapest listings on eBay, or tap a model name for the full live list here.

Under each model is the actual listing that price came from, so you can see whether it is the thing you want or a bundle, a variant, or an accessory that happens to share the name.

"Off retail" compares today's used price with what the model cost new. For models still on sale that is the current price; for discontinued ones it is the launch price, so it shows how far the model has depreciated rather than a discount you could get on a new one. A few models read "above" instead: they now cost more used than they did new, which is normal for a retired set or a part nobody makes any more.
