Pure sine wave inverter suggestions?

I need to charge an electric dirt bike. Its charger is AC only and I will pay the extra for a pure sine wave inverter. I had a MSW inverter for my microwave and it really did not like the MSW.

My CPAP runs from 12VDC.

Thanks all.

Why not just boost the DC with something like THIS? There is a lot of loss converting DC to AC then back to DC

That's an interesting product. Thanks, I'll look into it.

What do you think that thing is?
DC to DC chargers are inverters with converters in the same unit.

I think that thing generates 150kHz DC pulses and smoothes and regulates them to a higher DC output voltage very efficiently. It's a DC input switching power supply. Going through an inverter to create true AC, and then an AC to DC charger is an inefficient, but simple approach. Maybe 70% efficient at best.
