[brushless DC motor adoption, energy saving] I take in neighboring air in difference of atmospheric pressure by an aerodynamics design and amplify wind about 15 times and send even smooth wind. I bring about air volume of about 3 times than a conventional featherless electric fan by adopting a brushless DC motor of the electric power saving although being effective. [the 2in1 specifications that are holdings & desk, ] It is cordless and uses holdings and can use the everyday commuting, attending school and picnic, camping, festival outdoors. Because slipper mat made of silicon is installed, it becomes the desk electric fan and is usable at and a home desk. [three phases of air volume adjustment, USB charge] Weak average, strong no three steps are alterable whenever I push the one-button. It is the usb electric fan which embeds 18650 2000mAh large-capacity lithium batteries, and is operable consecutively in charge 2H for up to five hours. I can use an electric fan while charging it. I do not need battery exchange and can charge it from a USB battery charger, , mobile battery, and going out is convenient. As there is not an expensive safe wing, I reduce the risk of the accident touching by mistake than a conventional electric fan. It is usable in peace in the small child gairasharu family. I inhale air from 360 degrees and realize the strong ventilation by a design based on the discharge aerodynamics. Let's not boil the hive behind the head, and the air of the circumference is inhaled from 360 degrees by a loss. I bring about even smooth wind with a motor by way. Wind can be caused than an AC motor efficiently by adopting an energy saving brushless DC motor (direct current). With a few it, the power consumption is power saving nitsuganarimasu, too. Because a slipper is installed in the , I can use what I have by handy & desk combined use hand and use as a handy fan as a desk Mini electric fan. A conventional feather made the wind power that three phases of adjustment was powerful by adopting a brushless DC motor of the realization electric power saving and improved air volume of about 3 times than an electric fan. In use, can regulate a mode to preference freely, and is Switch; weak average strong; finish resembling it; a substitute is a possibility. It is USB electric fan 2000mAh large-capacity in-vehicle battery charger, PC, a compact electric fan of the correspondence including the mobile battery. When a battery runs out for going out by any chance, I am lighthearted and come. It is the usb electric fan which does not need the troublesome battery exchange, and can send air by the full charge for two hours for about 4-6 hours because with a built-in macroscale 18650 lithium battery. Whenever push the brief operation button with one-button, and push power supply ON/OFF, the button, is jaku with wind power → The inside → I change it with strong no turn. As it is only 120 g and the which it is easy to carry with a compact, it is to carry it. I play an active part in Fass, , watching , camping, a barbecue, a festival, the outdoors including the fishing in and summer. For prevention of fall, I keep a strap hall in the lower . ■A function, size: 18.5*9.5*2.5cm, weight: The length of 122 g (only as for the ), the USB cable: About 0.25cm, input: DC5V 1A~2.1A (USB charge type), a battery model: 18,650-3.7V, a charge time: About two hours (in the case of input 5V 1A), power consumption: 0.3W~1.2W, consecutive use time: About 3-5 time, air volume adjustment: /kyo out of weak/ ※It is an indication at the operation time. By use frequency and a condition (temperature, environment), it changes at the operation time. B07S38KV1B
