E-bike battery charge: how much battery you need
E-bike battery charge (500 Wh) draws about 120 W (80–200 W range), runs 100% of the time and uses 480 Wh per day. Start-up surge: 120 W.
A full charge takes ~550 Wh from the station; an e-bike is also a 500 Wh battery you can borrow via its USB port.
Battery needed
| Hours | Wh | Battery (Wh) | Inverter (W) |
|---|---|---|---|
| For 8 hours | 160 | 243 | 132 / 120 |
| For 24 hours | 480 | 728 | 132 / 120 |
| For 72 hours | 1440 | 2182 | 132 / 120 |

FAQ
How many watts does a E-bike battery charge (500 Wh) use?
Typically 120 W while running, with a range of 80–200 W depending on model and age. Start-up surge can reach 120 W.
How long will a 1000 Wh power station run a E-bike battery charge (500 Wh)?
About 5.5 hours on the clock, allowing for the 100% duty cycle, inverter losses and a 20% reserve.
What size power station do I need for a E-bike battery charge (500 Wh) overnight (8 h)?
About 243 Wh of battery and an inverter rated at least 132 W continuous with 120 W surge.
Can I run a E-bike battery charge (500 Wh) on solar during an outage?
You need roughly 320 W of panels in winter to replace a day's use (480 Wh), charging through a station with a big enough MPPT input.
