How is it now with the EcoFow wave 2?
I have read about some problems. Have they been fixed now? Is the device now running smoothly?

Hi, it's only for recharging the Wave 2 battery, which is optional. And frankly, at 12v, recharging must take a week...

I don't know if this is a good idea. There should be 10A permanently available at 220V, the cigarette lighter will probably be fused with max. 2A. If it works, you risk damaging the device.

Yes, but it uses a lot of energy and the cable gets very hot.

Hello!
Only indirectly via the additional battery or an Ecoflow Powerstation, which you charge while riding. If you take THE battery with you or already have it anyway, take a look at the Ecoflow Alternator, which is just coming onto the market. This would give you enough juice to run it for a long time.
