The 20,000mAh built-in battery runs the fan for 12 to 58 hours depending on speed — a full weekend of nights without hunting for an outlet. When the grid is out at home, the same runtime covers the bedroom instead.
02 — Fan + lantern
AIR ABOVE. LIGHT BELOW.
Four fan speeds handle air; a built-in LED lantern with three brightness settings handles light. The hanging hook puts it at the top of the tent where both work best, and oscillation plus tilt aim the air where you sleep.
03 — Remote & timer
SET IT FROM THE SLEEPING BAG.
Two output ports charge phones from the fan's battery while it runs. A remote control and a timer with 1, 2, 4 and 8-hour auto-off presets mean you set it once from your sleeping bag and let it shut itself down.
How it works
THREE STEPS
1
Charge it up
Charge the 20,000mAh battery before the trip; the same battery later charges your phone.
2
Hang or stand it
Hang it from the tent hook or stand it on a table, tilted toward where you sleep.
3
Set it by remote
Use the remote to set speed, lantern brightness and an auto-off timer — then leave it alone.
