55 of 56 units can run it. The smallest is the EcoFlow RIVER 3 Plus (286 Wh, about 6.1 h). 49 hold 8 hours of a laptop or phone with the calculator's 20% headroom.

A MacBook Air's adapter is rated 40 W (Apple's figure) and an iPhone's 20 W; both draw that only while charging hard, and less once the battery is full. These hours are therefore the shortest you would see.

What changes these hours

Charging from a USB-C port skips the inverter, so a laptop lasts longer than the AC figures here. Check the station's USB-C output is at least your laptop charger's rating.

The 0.85 allowance covers the inverter's conversion losses on average; at very small loads its own idle draw takes a larger share, and at very large ones the battery delivers a little less. Cold batteries hold less, and an older battery holds less than its rating. To plan a whole day with other devices and 20% headroom, use the calculator with 8 hours of a laptop or phone already added.

Also: a working day in a van, and every device.

Questions buyers ask

How many watts does a laptop or phone use?

Laptop (MacBook Air, charging): 40 W; Smartphone charger (USB-C): 20 W. Your own model's label or manual has its figure; put it into the calculator's custom row to size for exactly yours.

What size power station do I need for 8 hours of a laptop or phone?

452 Wh of rated capacity by the calculator's arithmetic (device watts × hours ÷ 0.85, plus 20% headroom), with at least 40 W of surge. 49 tracked units clear it.
