Generator 8500W (9500W Peak) 17L tank Works about 17h with 1 tank. Maximum Rental 4 days. For everything above 4 days it starts to make sense just buying one. So if you need one for longer you can just buy one! This version with key start costs 300€ but you can get them also with pull start for 250€, I got it on maarktplaats from a reseller, but it costs the same on other websites
