Unsure what board to post this in but this seems like the right board to do so. So I need something for my current setup that pulls about 150-160 watts on average. I recently purchased the image related (Jackery 300 plus w/ 40 watt solar panels) because it was on sale and it had the range of wattage I was looking for but the thing is, with both solar charging and wall plug it only seems to last an hour even though it advertises 8 hour solar charge use. I'm using it for my rog ally z1 extreme and a starlink just to game. If anyone has any recommendations let me know, I wanted something with at least 5-8 hour life but I'm not sure what to really look for. I don't know if another solar panel will help or if it's the generator itself, I was thinking about just getting the Jackery 1000 any advice is appreciated.

TLDR; Recommendations for portable generator that runs on solar for 150-160 watt setup with 5-8 hour runtime.
