EcoFlow Wave Portable Air Conditioner + Add-On Battery

Fast cooling: With 4000BTUs, Wave can cool your tent, RV, or small to medium space in 8 minutes flat. That's the fastest for its size.
Extended runtimes: Get 3hrs of cooling with the add-on battery. Extend to 8 hours with timed mode to keep you cool all night long by auto alternating between cooling and fan settings.
Cool your way: Use the 1008Wh Add-On Battery, DELTA Max, or DELTA Pro for an extra runtime of up to 12 hours without plugging into an AC outlet. Plug into an AC outlet for cooling without a battery.
Charge anywhere:  Wall outlets, solar, car or even portable power station charging mean you've always got cooling when you need it.

Carry or stow away: Weighing in at 17.4 lb, the add-on battery can be carried or stored for later use.
