Let's take a look:

structure diagram of a rechargeable screwdriver

1. Rechargeable batteries. Here we meet the first fundamental difference from the screwdriver. Removable battery no stead in the handle is a few cans. On the one hand it allows you to do the screwdriver more compact and easy to use, on the other - limits its time and power.

After all:

• First, replace the stranded power supply will not work. "Exhausted" the unit can only put in charge;
• Secondly, a large voltage is simply no place to place, to get the maximum torque, similar to that observed in screwdrivers;

Battery capacity is limited by the number of cans that fit in the handle

1. Button It has a power control system which depends on the extent and intensity it is pressed integrated radiator protecting against overheating. Everything is similar to the older brother;

Idle speed is adjusted by pressing the button

1. motor shurupovortnogo different from, usually smaller capacity, which is justified by the limited number of batteries. Construction, they have the same;

Advantages and disadvantages

With a conventional screwdriver to compare makes no sense, even though the battery costs more money, but, of course, is functional at times surpasses it. But with a screwdriver, on the basis of the above-described device can carry out some parallels:

Benefits

• lower price. in the power limiting effect on the final cost of the device;
• density. Motorized screwdriver to easily fit in your pocket, that allows you to have it with you, even in cases where a full set of tools to take is not possible;

The device has a relatively small size

• serviceability with his own hands. The device is lightweight and easily fits in your palm.

disadvantages

• less power. So to perform certain types of construction works rechargeable screwdriver is simply not enough. These include drilling or installation of gypsum boards;
• The lack of removable batteries.

To date, this defect can be avoided. For this will be enough to find a model with lithium-ion batteries. They are much less classical NiCd cans, due to which have the ability to be stacked in a separate part separated from the main body of the device.

Scope of use

So under what works rechargeable screwdriver is more in demand than the screwdriver?

For example, here in what:

• Assembly and disassembly of furniture Interior items. We bought a new computer desk? Viewed excellent power tools to help cope with the twisting of its fragments into a single structure. You need to move? Well, not to twist the arms of all bolts of furniture?

Compact battery screwdriver convenient to collect furniture, even a woman's hand

• Assembly and disassembly of the surrounding electrical equipment home. It is necessary to clean the system unit of a personal computer or open the power plate? Reporting tool will help you out here;

Electricians very effective use a cordless screwdriver in their professional activity

• Perform other small tasks around the house: the installation of paintings on the wall or shelf, chandelier installation, repair of children's toys and so on.

Even the replacement of the batteries on the remote from the toy helicopter can be accelerated and simplified by using such a useful instrument in the economy

In fact, the work list, you can use rechargeable screwdriver, can be very long. These include all the tasks on the loosening and tightening of bolts and screws that do not require too much torque. That is, until you do not have to disrupt the old screw connection or drill anything, you can not access the screwdriver. And there may have been better to take all of the drill.

species

What, then, are a screwdriver on batteries? Here in the first place should pay attention to their shapes:

types of forms

• Straight. Such a device is pleasant to carry, because more like a big fat pencil than on the tool for tightening of bolts and screws, but can bring some inconveniences when it is operating in a limited space;

Compact, but not always easy to use unit

• L-shaped. The most common form of electric instruments - a form of pistol when the handle at an angle passes the rest of the body. It is convenient to use, but sometimes cause inconvenience during transportation;

Demonstration of the operation of the storage screwdriver L-shaped

• T-. Inconvenient to store and transport, but allows you to screw the screw, even if the battery is completely discharged, and it is not possible to charge or time;

Example T-shaped tool, which does not cease to be useful, even when discharged

• universal. Most popular, as in this case, the handle can be rotated, changing its position from the forward to the L-shaped. The only negative - it is a gradual deterioration of the hinge mechanism.

As you have so handle and expose

types of batteries

Batteries may also differ in their physical properties, and then the most common are two options:

1. Nickel-cadmium. Invented it was still about a hundred years ago and to this day can "boast" a certain set of positive aspects, which include:

• Low cost;
• frost;
• Durability;
• Possibility of restoration;

Also, there are also negative aspects:

• The notorious "memory effect". That is, if you put in the charging instrument, the charge which has not yet run out, its battery capacity is reduced;

In no case do not put those batteries recharged for 5-10 minutes during the break. It is their irrevocably spoil them.

• The relatively large size. Many of these cans, as we have seen above, in the handle rechargeable screwdriver will not fit;

Nickel-cadmium battery occupies almost half of the entire device

1. Lithium-ion.

A fairly new development, which immediately captured their share of the market due to advantages such as:

• The lack of "memory effect." There can not be afraid of what will be a violation of the instruction charging;
• High performance;
• Smaller dimensions;

But in this case, it was not without its disadvantages, among which the most noticeable:

• Fear low temperatures. The frost has not come to work;

Do not leave the screwdriver runs on a lithium-ion battery for the winter in unheated premises. This will lead to battery failure.

• Shorter life;
• The higher price.

Selection and illustrative examples

How to choose a cordless screwdriver, so as not to regret later on your purchase?

First determine the shape and the battery, and then move on to the study of brands, with whom I have now also acquaint:

• "Vosch". The German firm, have long been proven in the market of construction tools exclusively on the good side. It offers a high quality, a wide variety of forms, wide application of Li-ion batteries and high price. Also, the presence of features are special storage container, both the device and used in combination therewith nozzles and the charger.

As an illustrative example I would like to propose to consider a model «Bosch GSR MX2DRIVE 0.601.9A2.101». This is the best screwdriver for professional furniture assemblers and builders engaged in interior finishing work, almost as good as the full screwdrivers. The considerable costs quickly pay off their performance. Technical specifications:

• «Einhell». Once this brand, too, it was a German, but for many years the products under this brand comes exclusively from China.

This inexpensive screwdrivers for life. That is, if you will need to hang a picture of the house or dismantle the system unit of a personal computer, they have excellent help out. But overloading them serious installation work is not worth it, not stand.

As an example, I want to offer a compact model «Einhell BT-SD 3,6 / 1 Li», which can be a good assistant in solving everyday problems. Technical specifications:

Sample model «Einhell BT-SD 3,6 / 1 Li»

• «Hitachi». This is the Japanese firm. Its products are characterized by elegant compact form, the possibility of adjusting the position of the handle, having an extra battery and plastic case. But it should be noted also a high enough price, and a large mass of finished units, which is somewhat unusual for a class of semi-professional power tools to which they relate.

For example, I propose to consider the model «Hitachi DB3DL2», which is due to its elongation and swivel handles allow even reach the most inaccessible places. Specifications:

«Hitachi DB3DL2» model sample

• "Zubr". Russian brand offering domestic product class, which at the same time boasts a decent quality, a wide variety of shapes and battery equipment, as well as low price. Only in the case of the acquisition of such tools do not forget to follow the manufacturer's recommendations. For example, it is not designed to perform drilling.

As an example, take a look at the model of "Zubr LP-3.6-Lee KN43" something resembling their outlines lady's gun. Specifications:

Sample "Bison LP-3.6-Lee KN43" model

• «AEG». Another brainchild of German designers have proven to be highly effective for many years regularly serve collectors of furniture and electrical household equipment.

For example Let us examine the model of «AEG SE 3.6 Li 413165", the ability to transform from a "boomerang" in extended pointer, which you can climb in the most remote places. Very much in demand by professionals working in the service station. Specifications:
