Camping weekend
Most camping trips need less watt-hours than the carton suggests, and more honesty about weight than the photos show.

If the job is phones, headlamps, a lantern, and maybe a laptop, a 200–300Wh station is the right size. The Jackery Explorer 300 is 293Wh and 300W continuous on the published sheet, at 7.1 lb. That is light enough to take from the car to the tent without making the station the heaviest thing in the kit.
Manufacturer “powers a phone for X days” figures usually assume a small charge and ignore the inverter’s idle draw. A more useful check is: 293Wh × about 0.85 inverter efficiency ÷ the watts you actually use. A 10W lantern and a phone that takes 15Wh to fill will last the weekend. A 50W electric blanket will not.
When 300Wh is not enough
A 12V compressor cooler that averages 40W while cycling can pull 300Wh in a long warm day. For that job, step to the 500–800Wh class. The EcoFlow RIVER 2 Pro is 768Wh and 800W continuous. It weighs 18.2 lb, which is a two-hand carry, not a pack item.
Skip if
You only need to top up phones overnight — a power bank is lighter and cheaper. Skip a 1,000Wh station on a walking-in campsite unless you have a cart; the extra capacity does not help if you leave it in the car.
Solar on a weekend trip is optional. A 100–220W folding panel can put back some of what the fridge used, in good sun. It will not keep up with a kettle. Charge from the wall before you leave; treat the panel as a top-up.
