How many watts does a laptop use — and what can run it?
A laptop on a 65 W USB-C adapter (Lenovo ThinkPad E14 Gen 6): 65 W is the ceiling, not the typical draw. Which power stations run it, and how long.
Adapter rating is a ceiling. ENERGY STAR notebook TEC figures cover off/sleep/idle modes only, so no daily average is given here.
The representative laptop is the Lenovo ThinkPad E14 Gen 6 (Intel). Lenovo's PSREF spec sheet lists a 65 W USB-C AC adapter supporting Power Delivery 3.0. The site uses 65 W as the running figure, but it is an adapter rating — the most the charger can supply — not what the laptop draws on an ordinary afternoon. That makes the runtimes below the short end.
What changes the draw
The draw is highest while the laptop's own battery charges and the processor is busy, and much lower once the battery is full and the work is light. Screen brightness matters too. ENERGY STAR's notebook figures cover only off, sleep and idle modes, so they are not used here as an average.
USB-C instead of the AC outlet
Because the adapter is USB-C Power Delivery, the laptop can usually be charged straight from a station's USB-C port, skipping the station's inverter — one of the losses the 0.85 runtime factor accounts for (method). Check that the port's wattage, listed on each station's card, covers your laptop. The tables below cover the AC outlet only.
No starting surge
A laptop adapter is electronics with no motor start, so there is no starting figure.
Reading the tables
Runtime assumes the full 65 W without a break. Example: the MARBERO M82 record has no maker factor, so the default 0.85 applies: 88.8 Wh × 0.85 ÷ 65 W = 1.2 hours. A 1,024 Wh station gives 13.4 hours by the same arithmetic.
Power stations that can run it
Pass = continuous output ≥ 65 W. Runtime = capacity × maker's factor ÷ 65 W, nothing else plugged in. Method.
