Rechargeable cooling system

 I want you to do this project by writing how it is easy and how it works. In other projects on this
subject, I wanted to disable the power supply and normal batteries even though it was less than the ones. In addition, with the USB cable types to determine the energy requirements of the fan to make you depend on the small-scale risks do not need to enter.

Materials using:

1) Ordinary flashlights are available in everyone's house. In the picture, the system in the torch is like that. A rechargeable battery and two plugs in the rear can be attached to the sockets, and the mounted plug can be connected to the iron and can be switched on and off. As a result, a rechargeable flashlight. This will not need the lantern you need for our benefit and we will bring the fan instead.



2) 1.4W one fan

3) Use an ordinary plug to charge.

Let's come to construction

First, we connect the red wire to the red wire and the black cable to the black cable.

In this part, I would like to point a finger at a point that you only need to connect the plug to charge, so unplug the power plug with the power strip without leaving the power strip on.



This is the last time, but as I said above, there is no need to keep the plug connected. Carry out the charging case.

I would like to say last, so please charge the case in case the fan is off while charging. And I could find the status of charging by plugging it and finding it dangerous. This charge status can be done either by plug-in or by other means, optionally with a suggestion. Portable easy project.
