Who it's for
Tent campers who walk their gear from the car to the site, and owners of small vans or truck cabs who want to set it up without drilling.
Caveats
- One battery lasts about 5 to 7 hours in Sleep mode and 2 to 3 hours in Rocket mode, so a full hot night needs two batteries.
- The AC runs on 48 V. A car's 12 V socket can recharge the battery but cannot run the AC.
- The battery uses lithium-ion 21700 cells, not LFP.
- There is no app. You control it with the buttons and the remote.
- Less cooling than the EcoFlow Wave 3 (5,280 vs 6,100 BTU).
