How to convert a cordless screwdriver to a network: 3 basic methods
Reconstruct a screwdriver based on old, unnecessary parts. The article presents several ways to alter the device that will definitely interest you.
1. Why convert a cordless screwdriver to a cordless one?
Battery-charged equipment periodically discharges if not used for a long time. This fact is a problem, since the main components deteriorate when the charge in the battery drops frequently. As a result, during the first signs of a breakdown, the battery holds less and less charge. In such a situation, complete breakdown of the part cannot be prevented, it is better to either replace it or change it to a new one. By the way, the cost of the first and second options will be the same.
Tip: If the user is going to work with hard surfaces, choose devices with rotation parameters of at least 20 Nm. This is the Sparky BR2 10.8Li-C HD mechanism.
The second reason is to remake the device. Quality of work. Owners of such devices will easily confirm that the torque process is sometimes interrupted. It is also annoying that the power is not the best level. Again, the partial discharge is to blame. The situation is saved by connecting the device to the mains supply. Here are the benefits we get in the end:
- The recharging time will be reduced and you can start working at any time.
- Functioning without restrictions, confidence that the device does not sit down halfway to the job done.
- Financial benefit: no need to periodically change the battery.
Tip: High-quality equipment is protected from breakages, which is located near the nozzle. Such protection is available for Bosch PSR 1200, Bosch GSR 12V-15 devices.
2. Choosing a power supply for a screwdriver
The task can be accomplished in several details. For example, with a laptop charger, this rework is considered simple and unassuming. Therefore, if an unnecessary network block from a laptop is left at home, you can use it. Second detail. Network block from a computer. This option implies a certain amount of knowledge and skills to work with a soldering iron. Another option is how to convert a screwdriver to a network one. Engage the desired inverter welding. In the next section, we will describe in detail how to implement our plans in all three ways.
Tip: Pay attention to the device parameters. For effective drilling, the rpm must be at least 1300. For example, Bosch GSR 1440-LI and Makita DF347DWE machines have this characteristic.
How to convert a cordless screwdriver to a network: 3 basic methods
It is not surprising that almost every house or apartment has a screwdriver. Unfortunately, devices based on a wireless network source often run out of power and break down. Since it is expensive to buy a new battery, most owners convert their cordless screwdrivers to cordless ones. In this article we will tell you how to remake the device using the parts at hand. We will also touch on the topic of why this type of equipment breaks down most often. Read carefully!
Connecting to an external battery
An external battery source can be of increased capacity, it is necessary to select a cell suitable for voltage. The battery is mainly used from an uninterruptible power supply. Alteration is not difficult, does not require large financial costs.
For alteration, you need a wire with a cross section of at least 2.5 mm, up to 2 meters long. It is necessary to disassemble the tool, remove the old battery cells, connect the wire to the terminals. Make a neat hole for the power cord, assemble the converted screwdriver and try it out at work.
DIY screwdriver alteration
There are enough craftsmen in the everyday life of the household, there are many ways how to convert a screwdriver to mains power. It is enough to provide the required voltage for the electric drive of the device.

In some cases, for alteration, it is enough to use the charger from the kit, it is available, because Supplied complete with a screwdriver. It is quite simple to remake such a structure, it is enough to disassemble the screwdriver, connect the output contacts on the charger with the drive wires. The voltage produced by the charger after the alteration corresponds to the technical characteristics of the drive, there is no need to worry about the safety of the electrical part. It is also worth noting that there is no need to disassemble the device completely. Only the wires designated for use need to be connected. A significant drawback is the size of the charger, it is not convenient to constantly move it during work and causes discomfort.
The power supply of the screwdriver can be achieved by several types of blocks. The body accommodates some of them, the rest are outside.
There are many ways to redesign a cordless screwdriver, all have pros and cons.
- In the case of the old battery, a place is organized for the finished power supply unit. The alteration is simple, no intervention in the electrical circuit is required, it is enough to carefully perform the work, to achieve a perfect appearance. The disadvantages are the time spent searching for a block with the appropriate voltage and size. Also, small devices usually heat up in an enclosed space, it is necessary to provide the device with ventilation by punching holes in the case.
- Installing a homemade energy source is a more complex solution, it requires finding the necessary radio parts and understanding the circuit. The advantages of this method of alteration are low financial costs, no losses when using a low voltage cable, no changes in the appearance of the device.
- An external power supply unit can be used when working in one place, since the device’s mobility and compactness are lost. There is also the cost of finding a suitable voltage for the electric screwdriver drive.
- The most common external type device is a computer power supply. The advantages are that it is easy to find on disassembly for an affordable price, there are no complicated rework processes. However, the bulky design will not be to everyone’s taste.
How to power a screwdriver while maintaining its autonomy
There are situations when you have to work in the absence of electricity. Powering a screwdriver without a 220 network is possible in several available ways. In such cases, if the battery of the device is faulty, and alteration from the mains is impossible, there are several ways to activate the wrench:
- Replace the battery cells inside the battery with new ones purchased from radio components.
- Using an external rechargeable power source such as a UPS battery.
- Connected and powered by car battery.
It is important to remember that any rework requires technical skill and safety.
Using a car battery charger
The principle is the same as using a computer power supply. It is necessary to purchase an old charger for the starter batteries. The modern fashion for compact impulse chargers has left analog linear devices with manual control of voltage and charge current behind. Therefore, such a device can be purchased on the automotive market for a symbolic cost.
Charger MAX INTER
It’s good if the voltage can be adjusted smoothly – in this case, your makeshift power supply will fit any screwdriver.
Converting it to a power tool is reduced to connecting the input of the electric motor to the power terminals of the charger.
Battery Disadvantages
- Needs regular recharging. Sooner or later, batteries will use up their cycle life.
- The cheaper the tool, the faster the rework time will come.
There is nothing wrong with that, but you should be aware that the manufacturer saves as much as you do. Consequently, the most expensive unit (namely the battery) will be the cheapest when bundled.
As a result, we get an excellent tool with a serviceable motor and not a worn gearbox, which does not work due to a poor-quality battery.
There is an option to purchase a new set of batteries, or replace faulty batteries in the unit. However, this is a budget event. The cost is comparable to buying a new screwdriver.
The second option is to use a spare or old battery from the car (if you have one). But the starter battery is heavy, and using such a tandem is not very comfortable.
External power supply
The idea is not as absurd as it might seem. Even a large and heavy buck rectifier can just stand near the outlet.
You are equally tied to the power supply, and to the stuck mains plug. And the low-voltage cord can be made of any length.
IMPORTANT! Ohm’s law says – with the same power, decreasing the voltage – we increase the current! Accordingly, the 12-19 volt supply cord should have a larger cross section than 220 volts.

If your tool is not too powerful, you can place the power supply in a handle or case from damaged batteries.
