Can I charge my Segway in the car?
Yes, buy an AC inverter. Plug it into your lighter and you can charge while you motor/boat/fly/etc. It is advisable to use at least a 150 Watt inverter. Note that while you could charge two Segways in your car, you would need at least a 300 Watt inverter and an inverter of this rating should be wired directly into the vehicle’s power system, not plugged into the lighter. You would be wise to have your inverter separately fused with spare fuses in the glove box.
