This compact exhaust fan mounts to a rolled‑up window and uses a three‑duct, three‑motor vortex design to pull hot air out of the cabin. It runs on a solar panel in bright light and switches to USB power when sunlight is insufficient, offering flexible operation for different weather and parking conditions.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this fan lower interior temperature on sunny days?\u003c\/h3\u003e\n\u003cp\u003eThe EOHMAK fan accelerates air exchange by drawing hot air out through three separate outlets. Its high‑speed motors spin up to around 5000 RPM, creating a vortex suction that removes trapped heat faster than a single‑outlet unit. Faster exhaust reduces cabin heat accumulation, making re‑entry more comfortable.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eThree independent air outlets for increased airflow\u003c\/li\u003e\n  \u003cli\u003eVortex duct geometry to move air efficiently\u003c\/li\u003e\n  \u003cli\u003eUp to 5000 RPM rotation speed for rapid exhaust\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I use it when the weather is cloudy or at night?\u003c\/h3\u003e\n\u003cp\u003eYes — the unit offers two power modes: a rooftop solar panel for daylight operation and a USB cable for low‑light conditions. Plug the included USB cable into a portable battery pack, car USB port, or other 5V source to keep the fan running when sunlight is weak. This dual supply ensures continuous ventilation regardless of weather.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSolar panel harvests sunlight for cord‑free daytime use\u003c\/li\u003e\n  \u003cli\u003eUSB input provides reliable power in overcast or dark conditions\u003c\/li\u003e\n  \u003cli\u003eCompatible with portable power banks and car USB chargers\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow easy is installation and will it damage my vehicle?\u003c\/h3\u003e\n\u003cp\u003eInstallation is designed to be tool‑free and non‑invasive: fit the fan to an open window, adjust the rubber sealing strip, then roll the glass up to secure it.
