How to Make a Wireless Charger for a Laptop

Sometimes you must had thought of getting rid of long wired changers. So this article will help you to create a wireless charger for your laptop.

Wireless charging is the most recent craze in the world of electronics. Using a well-known phenomenon of physics, chargers now use induction to transmit power wirelessly from one point to another. This phenomenon has been very recently exploited commercially, allowing the advent of wireless chargers, almost all of which use the same technology. Induction has gained popularity it has almost the same efficient as wires, and if the magnetic field of the receiving device and the emitting device are almost fully linked, it offers extremely efficient transfer of power, and even reduces the risk of fire since less wires and less insulation is involved.

To make a wireless charger for your laptop, you will need a basic understanding of physics to make sure that you know what you’re doing, and a basic knowledge of electrical paths, to make sure you know which wire goes where. To begin, you will need an AC-DC converter. This is one of the most important parts of the entire setup, and is critically important to prevent your laptop’s battery from being damaged. Next you will need two metal or plastic pipes about a foot long and about 3 inches wide, which one being about a fourth of an inch narrower than the other. Metal, possibly iron pipes are always advised since this allows for more efficiency in the linking of the magnetic fields from the source to the receiver.

Get some insulated wire and make about thirty loops around one of the pipes. The two ends of this wire will go to two ends of an AC socket. Make sure you put appropriate resistance on the wire depending on what your household voltage is. Once this is done, your source magnetic field is ready. Take another wire and loop it thirty times around the other pipe. Make sure the wires are well insulated. The two ends of this wire will go to the AC-DC converter. AC-DC converters have many settings so select the source voltage correctly and the final voltage correctly. The final voltage will be around 15-25V DC, depending on your laptop. The outgoing wires from the AC-to-DC converter will link up with the computer’s charging plug, which in turn will go into your laptop’s charger port.

To charge your laptop, put the thinner pipe inside the thicker pipe, and switch on your wall socket. The phenomenon taking place here is coaxial induction, a very efficient form of induction. The induction coils make up the wireless power transfer mechanism, and the AC-DC converter converts the final transmitted power into DC so it can be safely used to charge your laptop.

Both parts of the charger can now be neatly put inside a wooden or plastic box, and the pipes with the coiled wires around them can be placed coaxially whenever you need to charge your laptop. This is a simple method to make a wireless charger which ensures that you can wirelessly charge your laptop without the risk of damaging the battery or the laptop itself.
