マキタ１８Vで動くポータブルインバータ電源は大丈夫？

Good morning. While browsing Amazon, I discovered an inverter power supply that can generate 100V from a Makita battery. Sometimes, temporary power installation at a job site isn't completed in time, and I want to use floodlights to brighten up the site in places where there is no power source. That's when a portable power supply comes in handy! However, it costs over 100,000 yen, so it's not something I can justify. Since it has to be brought to the site, there's the risk of it being damaged or soiled, and it's expensive equipment... I was wondering if there was a way to use 100V at an affordable price. This piece of equipment caught my eye, but is it actually usable? Is it okay to use it? This is the video I used to test it. I hope it will be helpful for those considering implementation.
