Each domestic master when choosing a tool for work tries to find a universal option that can be used for different purposes. Such equipment includes rechargeable screwdrivers, they are indispensable in the absence of electricity and are able to work in hard-to-reach places.

But the equipment market is so great and diverse that the differences between the offered goods and their characteristics need to know.

Equipment device

All screwdrivers have a single structure and components, they consist of:

• engine. As a rule, manufacturers choose a valve type without collector brushes. It gives silent equipment and high performance;
• battery. From the power of which the duration of work without recharging depends;
• gearbox that allows you to perform work at several speeds;
• regulator;
• the cartridge directly in which the drill or bit is inserted.

Classifications and differences

Before you choose a battery screwdriver worth considering its capabilities and functions. Two types of equipment are offered on the market:

• basic, designed to screw the screws. The patron structure allows you to insert only a cruciform nozzle, so the front of the work is limited;
• universal, which possesses a cartridge suitable under the set of nozzles. The volume of work increases significantly, but the price of equipment increases.

There are many classifications, the main separation of equipment for an ordinary consumer:

• professional with greater power. These aggregates are characterized by ease of work exclusively for an experienced employee, in addition, they are not suiced. Experts do not recommend choosing professional rechargeable screwdrivers due to the fact that they are faster than the battery, after several years of use, equipment will come into disrepair;
• household, who choose most of the masters. Manufacturers offer excellent performance to perform repair work at home or in the country. Of course, the power of such devices is small, but the duration of functioning is much longer - you can continuously work for about two hours. At the same time, the price of 2-3rd is lower than professional screwdrivers - it gives tremendous popularity among consumers.

It is clear that a professional screwdriver is characterized by improved ergonomic characteristics, ease of weight and a set of replaceable handles. But these improvements do not always justify the excess of financial costs.

Depending on the installed cartridge distinguish:

• rechargeable screwdrivers designed to screw the screws and small screws. They are characterized by a weak power of 120-150 W, while the compactness of the models allows you to perform work in a limited space;
• wheel, designed for the nozzle square. Such a tool is ideal for assembling the metal structures, because the process of clamping clamping process is accelerated;
• pulse screwdrivers are convenient in working with long self-draws, additional vibrations contribute to careful tightening of the compounds. But these representatives are rarely found due to their impracticality and small service life;
• private units that perform translational screwing.

In order to determine which screwdriver rechargeable is better, you need to know the front of work and carefully examine the characteristics of the proposed equipment.

Constructive features, or what to pay attention to

The home master for the successful completion of the tasks is important, the following features are important:

• the presence of an accumulator of sufficient power. There are three types of devices - nickel-cadmium, which is more common due to its availability and long service time. The second version is the battery lithium-ion - more expensive, but environmentally friendly. The third type of device-metal-hydride is characterized by a high cost, but does not withstand low temperatures;
• the torque indicator, as a rule, in most models varies from 11 to 36nm. The greater the value, the easier it will screw the screws or drill holes;
• smooth start and speed switch - these functions allow you to adjust the tool for the material being processed;
• reverse, which, if necessary, switches the direction of rotation of the cartridge. For this purpose, a separate button is proposed, when you press the screw screwing, you can go to the twisting;
• the shock mechanism allows you to quickly drill holes in concrete and brick structures;
• the presence of LED lighting gives additional convenience in many situations;
• the quick-swampling cartridge contributes to the emergency replacement of the nozzles;
• the spindle lock is especially important if you need to clamp a self-press manually.

When choosing a battery screwdriver, it is worth considering many factors. But there is a difference when the tool is applied regularly or on occasion. With minor work in order to save on some features, you can refuse, and in large volumes, any trifle can turn into a noticeable drawback.
