I need some kind of battery/power bank to provide 230V for some measurement equipment/laptop etc. that preferable doesnt weigh a ton like a car battery, and can last at least as long as a car battery but preferably longer.
Anyone has some suggestions/experience with solutions to look for?
I need to power devices with a total consumption of 125W for either 4-5 hours(using two battery packs to reach 9-10 hours) or 9-10 hours on one battery pack
