How many watts does an e-bike charger use — and what can run it?
A 48 V, 2 A e-bike charger (Lectric 3-pin) delivers 109 W; the wall draw is higher. Which power stations can charge an e-bike, and for how long.
Lectric: most Lectric e-bikes charge within 6 to 10 hours with this 2 A charger.
The representative charger is Lectric eBikes' 3-pin charger for its 48 V bikes. Lectric's product page lists an output of 54.6 V DC at 2.0 A, which is 109 W, and an input of AC 100–240 V, 2.0 A max. The site uses the 109 W output as the running figure. That is an undercount: the charger's own conversion losses mean the outlet supplies more than 109 W, so the runtimes below lean long.
What changes the draw
A charger delivers its full current for most of a charge and reduces it as the battery approaches full. Lectric says most of its bikes charge within 6 to 10 hours with this charger; the page assumes 6 hours a day, 654 Wh. Faster chargers draw more watts for fewer hours.
No starting surge
A battery charger has no motor start and no starting figure. The deciding number is continuous output: stations rated 100 W or less fail; every station rated 300 W or more passes with room to spare.
Reading the tables
Runtime is time at 109 W, not a number of charges — the e-bike battery's capacity is not in this page's data. Example: the EcoFlow RIVER 3 Plus record has no maker factor, so the default 0.85 applies: 286 Wh × 0.85 ÷ 109 W = 2.2 hours of charging. To compare with your bike, check the watt-hours printed on its battery against the usable energy of a station.
Power stations that can run it
Pass = continuous output ≥ 109 W. Runtime = capacity × maker's factor ÷ 109 W, nothing else plugged in. Method.
