This diagonal desktop fan is a small and portable device that's handy for personal, close-proximity cooling. It's powered through a USB connection, such as the one in your computer, a power adapter that you plug into a wall outlet, or a portable power bank. Despite their compact size, the USB fans can be powerful, and offer different speed settings. They won't cool down an entire room, but they can keep you comfortable when used at a close distance, such as an office desk or bedside table. This table fan has LED lights, low power consumption, lights up the night, drives away the darkness, makes your baby feeling safe, and convenient for moms and the elderly to use in the dark.
