Portable power stations, compared on what the makers actually publish
Every capacity, output figure and cycle rating on this site is read from the manufacturer's own specification page and stored once, in one registry. No hands-on tests are claimed, no scores are invented, and where a maker does not publish a number, the page says so instead of guessing.

Four brands, one registry. Every capacity, output and cycle rating on this site is read from the maker's own specification page.
Every unit covered, at a glance
Ranked by the score described on the method page, which is calculated from published specifications rather than opinion. Capacity tells you how long a unit runs something; continuous output tells you what it can run at all. A large battery behind a small inverter will not start your appliance, however many watt hours it holds.

What people actually do with them
Four situations these units are bought for. A weekend away from a socket, a van that needs mains power, an outage that lasts longer than the phone battery, and a panel array that has to refill the pack before the sun goes down. Each one asks a different question of the same specifications.
Work out what it will actually run
Most runtime claims quietly assume two things: that the inverter loses nothing turning stored DC into mains AC, and that your appliance draws its rated power continuously. Neither is true, and on anything with a compressor the second assumption changes the answer more than the battery size does.
The run time calculator puts both assumptions on screen and lets you move them, so you can see how much of the answer is arithmetic and how much is guesswork.
Three numbers worth understanding before you buy
Cycle life is meaningless without its endpoint. A unit rated for 4,000 cycles to 70% of original capacity and one rated for 4,000 cycles to 80% are not making the same promise, and the makers here do not all use the same endpoint. Wherever this site quotes a cycle figure, the endpoint comes with it.
Surge ratings are not one measurement. BLUETTI's Lifting Power and EcoFlow's X-Boost run appliances above the rated output by lowering voltage, which suits a kettle or a heater but not a motor or a computer. A conventional surge rating means something different: a brief tolerance for start-up current. Comparing one against the other as if they were the same number is how people end up with a unit that will not start their fridge.
Headline charging times often combine inputs. A figure that looks dramatically faster than a rival's sometimes assumes mains and solar feeding the unit at once. This site quotes the mains-only time, because that is the situation most owners are in.
What is not here
No prices. Showing one means committing to keeping it current, and a stale price is worse than none, so every unit links to its Amazon listing where the live figure is. No test results either: these units were not bought, opened or measured, and the about page says so plainly. What this site does is read the specifications carefully and explain which differences actually decide a purchase.
