Great idea, you can find a small portable solar panel to keep your battery fresh at all times as long as there's sunlight, they are about 8x10" I use it while at remote areas.
This was a classic portable power hack about 10 years ago! (2007?) thanks for bringing back the classic Vagabond to memory! 😃 I wonder if a normal inverter would work - though perhaps not pure sine wave.
You want a samilex 300 watt pure sine wave inverter. And a battery at least 12 amp hours to mimic a vagabond. You can pick up a lightweight litium sla equivalent for 50 quid.
I'm not finding the original Paul C. Buff inverter anywhere. So I was considering getting a 2,000-watt pure peak sine inverter (there are many varieties and sources available) and a 12 volt / 35 amp garden tractor battery to power 2 Godox 200 watt studio strobes. Is there anything else that I should be considering ?
What you need when you buy an inverter is a (Pure Sine Wave) type & get a deep cycle marine battey or head to the wreckers for a junker!. Marine batteries can be used until they are dead flat & will be able to recharge, if you drain a normal battery to nothing it may not be able to charge!.
