USB to DC 7.4V Control Cable: A Simple Solution for Cooling Fan Jacket Users

Cooling fan jackets are clothing items that have built-in fans to keep you cool in hot weather. They are popular in Japan, where they are used by workers in extreme heat conditions. However, they need a power source and a fan speed controller to work properly.

The USB to DC 7.4V Control Cable is an accessory that lets you connect your cooling fan jacket to any USB power source, such as a power bank, a laptop, or a car charger. It also has a switch that lets you adjust the fan speed to low, medium, or high. It is compatible with most cooling fan jackets that use a 7.4V battery pack, such as the ones from Cooling Fan Jacket.

The benefits of the USB to DC 7.4V Control Cable are:

• It gives you more options to power your cooling fan jacket, instead of relying on a battery pack.
• It allows you to customize your cooling experience by changing the fan speed.
• It is affordable and easy to use.

The drawbacks of the USB to DC 7.4V Control Cable are:

• It does not work with cooling fan jackets that use a different voltage, such as 12V or 24V.
• It does not have a built-in battery or a LED indicator.
• It does not improve the appearance or the noise level of your cooling fan jacket.

The USB to DC 7.4V Control Cable is a useful accessory for cooling fan jacket users who want more flexibility and convenience in powering and controlling their jackets. However, if you want a more advanced and reliable solution, you might want to consider a battery pack, a solar charger, or a car charger instead.
