Trivial; look at any camera flash unit built in the last several decades.

However you have totally missed the point; voltage and the weight of the
converter is irrelevant as it is the total power that determines the
weight of it all.

BTW, here are some real world power to weight ratios:

Boeing 777 engine 10 kW/kg
1985 Chevy Celebrity 300 W/kg
Lithium-ion battery 85 W/kg
nickel-metal battery 116 W/kg
zinc air fuel cell 500 W/kg
