Jackery unit question

I am looking to put this air dryer in my travel trailer for humidity control. There is no power available where it is parked. Which Jackery unit would power one of these and for how long? I see on their site that solar panels are available for charging. Thanks in advance as I am not familiar with these Jackery units.

Jackery, Anker, Ecoflow etc are typically rated in watt-hours to measure how much energy they will be capable of storing. This article will help guide you through the math

Your humidifier draws 130 watts, so it should consume 130Wh in one hour of non-stop runtime. If you got a Jackery 1000 (1264Wh), it would operate for for just over 8 hours on one charge. 1264Wh x 0.85 discharge efficiency ÷ 130 watts = 8.26 hours

 

I did my first test last night. I ended up getting the Ecoflow Delta 2 that is 1800 watts and 1024 watt hours. I started the unit at 8 pm at 95% battery charge. When I got up at 530 it was at 7%. The air dryer actually pulled 122 watts. It cycles on and off every few minutes. 400 watts of solar should be able to get it through the night until the sun returns. Keep in mind that this dryer is for 1000 cubic feet. I'm considering a 500 cubic foot model for the travel trailer and that one only pulls 76 watts. I'll have to measure my open space in the trailer when it's closed up but I beleive it's right around 430 cubic feet as a guess.
