Don't make it too complex

When figuring out your initial purchase of an EcoFlow Power station. Let's say for a week away camping...

Don't overthink too much. What you need to do is figure out how much wattage you will be using per hour, this can easily be done by seeing the watts of the units you're needing to power e.g fridge, lighting, entertainment etc. Then add all that together and multiple by the time required with/without the use of a solar panel (overnight). Both considerations are equally important.

Then to continue to keep powered for that overnight, you'll need to power it with a big enough solar panel for the day time charging to be sufficient enough, e.g using approx 200watts an hour, maybe you require 400w+ of solar panels, (more than what you require is always better) just to be on the safe side.

Don't forget though, the inverter uses power also, so do not underestimate your usage requirements and get caught out overnight when there is no solar as you did not sufficiently charge the Power station.

Also things to take into consideration is, will there be enough solar production due to poor weather etc.

That is what catches people off guard also. That is where consideration into bringing a second power station as a back up.

Keeping powered is important for longer trips as the weather can fluctuate day by day quite considerably!
