Can you get a large container that will hold water., then you can use the karcher directly from that, you could then use just a short piece of hose with suitable end to connect to the karcher, but, it’s very important to prime the hose first, ( fill with water) or you will burn out the motor on the pressure washer, ( don’t ask me how I know) ..
For temporary water tankage in the supply outage that usually follows severe typhoons here (due to reservoir siltation) I have used a bin bag stabilised within a "Swiss roll" arrangement of cardboard/Coroplast signage (commonly blown around by a typhoon) or camping/yoga mat. You fold the top of the bag over the roll and as the bag is filled with water and the "Swiss roll" expands it comes under tension and stabilises the whole thing, plus the overlap stops the roll getting wet, important if its cardboard.
As well as taking up minimal space when empty, this can be fitted under a downpipe (perhaps the only available water source post typhoon) without cutting the pipe or risking leaving a bucket out. Buckets are at a bit of a premium in these situations, and sadly, when the going gets tough, the tough tend to knick my bucket.
Seems this could serve as an outdoor temporary reservoir for your pressure washer.
I've never used a pressure washer, but logically the supply side seems likely to be under negative pressure, so a fairly stiff hose, which I'd expect to come with it, would seem to be indicated. I'd expect a compact "lay flat" to collapse.
