Flexibility: Most of the USB fans we chose can be adjusted to ensure you get the proper placement for maximum exposure to the cool air — or less of it, if you don’t want a full blast. 1. TRUSTECH Portable USB Fan Although all of the handheld fans in our round-up are a decent, portable size, this dinky offering from EasyAcc beats them all when it comes to compactness.

NOTE: The rechargeable battery is in the fan so you don't need to buy another battery or load the battery. Just use it and charge it when its battery runs out of power. Please do not place and direct sun light! We found some popular USB fans with an array of features that make them the best choice in different situations. What You Need to Know Before Buying a USB Fan At the peak of summer, a large tower fan can be handy for keeping a single room cool, but isn’t so effective at keeping you cool when moving from room to room. Size and Portability: All of the USB fans in our guide are under 10 inches tall — one is under five inches tall — and only one weighs more than one pound. Some have batteries built into them, which allow you to charge them at home, and take them anywhere. The VersionTech Handheld Fan is a great all-rounder. With a choice of three speed levels, this small but mighty six-blade handheld fan can deliver everything from a cooling breeze to a strong wind, up to an impressive three metres in an instant.The Jhua Handheld Fan has a choice of two speeds, which deliver an impressive breeze, despite its size. The soft blades won’t hurt your hands, but as they’re not surrounded by a protective case – as some of our other choices are – make sure you keep hair well out of the way. Anyone who’s been through August (or say, any month at all in Florida) can tell you how dependent we are on air conditioning. But we can’t always be indoors, and when it comes to cheap and portable ways to get cool, there are few solutions better than a personal fan. USB Rechargeable】JISULIFE mini hand fan is USB rechargeable with only 3 hours to get it fully charged. It supports USB charging by USB charger, car charger, or computer. While it’s not the shortest, you probably won’t use it at its full height because of its marquee feature: an ultra-flexible base. This USB fan doesn’t have a metal or plastic frame; rather, it stands on three, tripod-like arms that can be wrapped around any thin surface. This allows you to securely attach it to the headrest of a car, side of a beach chair, or treadmill.

USB fans are less powerful than a full-sized fan, but that’s to be expected given their size; still, it’s way better to have some way to cool yourself down instead of sweating and being uncomfortable. Unlike traditional fans, which are big, bulky, and need to be plugged into an outlet, the best USB fans are small, portable, and draw power from a USB port. You can plug them into your computer, a power bank, or even your car’s cigarette lighter if you have the right adapter.The larger battery also contributes to this USB fan’s weight: at 1.8 pounds it’s not heavy, but it’s a lot weightier than other fans in our guide. It’s also the tallest fan we recommend at 9.8 inches. The additional height was required to support this fan’s three blades, which are eight inches long.
