How to connect an electric screwdriver without a battery

Is mobility important?

Once the battery becomes incapable of holding a charge, the electric screwdriver becomes a completely useless tool. Buying a new charger is impractical, as its price is often up to 50% of the cost of a new model. That’s why the idea of converting the tool to mains power is a perfectly justified decision.

It is possible to restore the characteristics of the battery, but this option is still a half-measure, because the situation will repeat itself in the future. However, before choosing a solution, you need to think about what to do with the mobility of the tool. Is it really necessary?? There are 2 options for the potential modification of an electric screwdriver:

  • The tool with an external power supply. In this case, a separate device is made. It is not so terrible, because even a bulky structure can be placed in close proximity to the outlet. But you will have to put up with limitations associated with the length of the PSU cable and the power cord.
  • an electric screwdriver with a power supply built in place of the battery. This way of modification will make it possible to avoid assembling a bulky structure, significantly limiting the use of the tool. But in this case the problem of access can be also caused by length of power cord. But you can use compact devices in this capacity. They can be purchased or existing power supplies, if they fit the characteristics.

Methods of “revival” of an electric screwdriver are very different. Nevertheless, each of these options finds supporters, as it meets the different needs of owners of cordless tools, whose operation suddenly became impossible.

Power supply options for an 18 V electric screwdriver

Mobile electric screwdriver on the battery is widely used in construction. One of the significant disadvantages of the model is the wear and tear of the battery, when worn out you have to buy a new electric screwdriver or look for a battery. The non-standard decision suggests radio amateurs to make with their own hands a power supply for an electric screwdriver 18 V.

Options on how to make

If the power supply also fell into disrepair, then do not get upset, as there are other options how to power an electric screwdriver:

PC power supply

Power for an electric screwdriver can serve as a block from a PC, which is much easier to find than a new battery for the device. The advantage of the power supply from the PC is the fact that at the output it is possible to obtain different values of current, which is considered very important.

In the design of the power supply from PC has a cooler that provides cooling of the transformer and components, so you can immediately note that this type of power supply is durable, and in the next few years you will forget about the problems with the electric screwdriver.

Old inverter welding

To power an electric screwdriver, you can use an old inverter welding, but you will need skills in electrical engineering theory. After all, in this case it is necessary to add a secondary coil of the transformer, which will make it possible to obtain at the output quite a suitable current to power the electric motor of the device. Therefore, before you connect an electric screwdriver to a welding machine, you need to measure the output current and voltage, which should match the values of the device.

Car battery

The last option is a car battery, which can be connected to a screwdriver and used in places where it is impossible to get 220 volt power. The disadvantage of such a device is that you can not work long with an electric screwdriver, because the car power supply quickly runs down. Therefore, if the regular ibp of an electric screwdriver refuses to function, which happens very often, then you should not rush to get rid of the device, just give a few hours of time and the device will work even better than with a battery.

How to convert a cordless screwdriver in the network in different ways

How to repair the technique with their own hands

A wonderful helper in the household. a cordless screwdriver. This tool will be with you everywhere, but it works exactly until the battery runs out, but the number of charge cycles it has is limited, even from idleness, the battery can go bad. Batteries live about three years, and after this time you will have to replace it. You can save the tool by converting it from cordless to corded, and there are various ways to do so.

Mounting the finished power supply unit in the housing of an old battery

If it was possible to purchase a PSU on the market with the appropriate performance, installation and remodeling is carried out in a few simple steps:

connect, electric, screwdriver, battery
  • Dismantle the old battery case, remove spent cells.
  • Install the new power supply so that it is tightly against the case, if necessary, you can glue, connect the high voltage wires (output from a 220 volt outlet).
  • Connect the low voltage terminals to the power supply of the electric motor of the wrench, in the absence of contacts, the wires will have to be resoldered.
  • Reassemble the case after remodeling and install the unit on the electric screwdriver.

Mounting the ready-made power supply in the housing of the old battery

It must be remembered that compact power units warm up in an enclosed space, so it is necessary to drill several holes on different sides of the housing for ventilation.

How to connect to the charging station

Before deciding whether you can charge the battery of an electric screwdriver with a charger, you must remember that the charger unit of an electric screwdriver supplies a low voltage, with a long wire voltage is lost, so it is rational to connect through a meter cord with a cross section of 2.5 mm2 or more.

  • To the contacts of the charging unit of an electric screwdriver are attached wires. Remove the defective power cells from the socket.
  • A groove is made in the housing and the cable is passed through. It is suggested to seal the point of entry with elastic material so that there is no backlash and the cable is held reliably in place.
  • Since the socket after removal of unusable elements has lost gravity, it is recommended to restore balance by putting some weight in the vacated space, otherwise the hand will be very tired while working, eventually harming the health of the joints, ligaments.
  • Connect the cable and previously attached wires together, and assemble the case.

Before you decide whether you can charge the battery electric screwdriver charger, you must remember that the charger unit electric screwdriver supplies a low voltage, with a long stretch of wire voltage is lost, so it is rational to connect through a meter cord with a cross section of 2.5 mm2 or more.

  • To the contacts of the charging node of an electric screwdriver are attached wires. Spoiled nutrients are removed from the nest.
  • A groove is made in the case, the cable is put through it. It is suggested to seal the entry point with an elastic material so that there is no backlash and the wire is held securely in place.
  • After removing the unsuitable elements the socket should be unbalanced by placing some weight on the empty space, otherwise the hand will tire a lot, damaging the joints and ligaments over time.
  • The cable and the previously attached wires are connected together, the housing is assembled.

Background

A long time ago, when I moved into a new apartment, I received as a gift a so-called “household screwdriver” under the brand name PRORAB 1112 B1N. This is a simple Chinese device, hundreds kinds of which are sold in our construction and not very much in construction supermarkets. It played a role in the move. it was a mixer, and was used for assembling furniture and screwing screws on the threshold, and then was undeservedly forgotten. I have got a commonly used Hitachi DS12DVF3 in use, and the PRORAB together with its Chinese battery was left on the loggia.

Some pumps are equipped with a grounding socket, of course, it is absolutely necessary to connect it even more important in the presence of water. Other pumps are double insulated, this simply indicates that the pump is better protected, but it does not eliminate any electrical hazard. There are circuit breakers or differential switches that prefer the latter, it will cost you much less. Since your home is forcibly equipped with a switch, it’s not worth investing in a redundant.

Why convert a cordless screwdriver?

Nothing complicated, the only thing you really need is to check the power required by your installation, and the power that can provide your power source as much as possible. Sockets are very often designed to hold a maximum current of 16A, if you have multiple sockets in the same room, this intensity must be shared between all those sockets, so think about taking into account what is already connected to your computations.

Three years of storage on the freezing loggia did not spare the bank, and after finding the screwdriver during spring cleaning, it was no longer possible to use it. the power was enough for a couple of screws. At the same time, work for an auxiliary screwdriver/drill was available. when making household furniture, it is very annoying to change tooling.

That’s how I came up with the idea of turning an old cordless screwdriver into a cordless screwdriver. To do it, of course, with his own hands. a new Pro Arab costs 1500 p., replaceable battery for it. 1200 p. The choice of the thrifty owner, as they say, is obvious. convert with their own hands in the network.

Reminder. What you should know is that these cables are connected to your electrical panel and protected by a fuse. Ballast with built-in compensation Power 400W. is the power of your lamp is not the ballast, the excess is released in the form of heat.

If you have a second number indicating a much higher intensity, it corresponds to that of the bulb on the ballast output. Always for our own ballast we have 400 watts for 6A. To know the actual amperage of the device, it must be measured with either an ammeter or a meter.
