20000mAh Battery-Powered Outdoor Fan
The Warmco D4 is a portable outdoor fan with an integrated 20000mAh battery that delivers up to 48 hours of runtime on low speed and 15 hours on high. A brushless motor drives five silver blades across four adjustable speeds, while a built-in LED lantern and hanging hook add campsite illumination. The unit weighs 770 grams and folds to a 1.77-inch profile for packing.
Campers and Light-Travel Users
This fan suits anyone who needs overnight cooling and light without mains power, such as tent campers, cruise passengers or homeowners preparing for outages. The 5V/2.4A output can top up a phone in an emergency. Buyers who require continuous high-speed airflow beyond 15 hours, or who need a fan that mounts permanently to a ceiling or wall, should look at a different product.
Fits in a Backpack, Charges Your Phone
The slim 1.77-inch depth and foldable stand let the fan slide into a backpack or sit on a desk without monopolising space. A 5-volt input recharges the battery, and the USB output frees you from carrying a separate power bank for small devices. The detachable cover simplifies blade cleaning after dusty trips.

Questions about this item
What type of USB charger is needed to recharge the 20000mAh battery?
The fan draws 5V input power, so any standard USB charger or power bank that supplies 5 volts will recharge the built-in battery.
Can the foldable stand be used on the same surface as a larger 44-inch blade fan without interference?
Yes, the D4 measures only 8.27 inches wide and 1.77 inches deep, so it occupies far less space than a 44-inch blade fan and will not interfere.
How do I confirm the brushless motor is running at the advertised sub-45dB level on speed 1?
The smart display shows the active speed setting; select speed 1 and the unit will operate at its quietest level, which is rated below 45dB.
