I've looked into it a bit as I'm in a similar scenario, council garage/lockup with no power or water.
The thing with the portable power stations other than the £500 price, it seems that once you calculate mAH, you actually don't get many minutes of power tool time before it needs charging. Unless I'm doing my calcs wrong and someone wants to correct me. So it probably makes more sense (although I think it's more money) to invest in battery powered tools rather than corded, and individually battery powered LED lights.
If you've already got the corded tools, it's not ideal.
Not at all - go ahead, it’s an interesting subject/something I’d like to hear more about.
