The screwdriver is an indispensable tool for the home. Thanks to him, you can quickly hang a shelf at home, assemble a wardrobe or install a new kitchen set. The magazine "Vyboved" has compiled a rating of the best screwdrivers for home use. One of the leading lines in it is occupied by the Sparky screwdriver. The models of this brand are reliable in use, very light, they are comfortable to hold in the hand, and their cost is low.

Choosing a screwdriver

For high-quality and easy use, the screwdriver should be light in weight, have a reverse motion (reverse) to release a stuck screw, it is desirable that the "blow" function is available, as well as several speed modes. Another important aspect is torque. Usually, for wood, devices with a minimum torque of no more than 15 rpm are used. To the maximum, it is more efficient to purchase a screwdriver with the highest torque, for example, professional ones reach more than 1,000 revolutions.

Choose a screwdriver for yourself: it should be convenient to use and fit exactly under your palm. It will be useful to have indicators of charging and / or overheating.

Modern screwdrivers are rechargeable, that is, they do not have a mains wire, but are only charged from the mains. Therefore, the choice of a battery is an important task for further operation. After all, if your instrument is constantly "on charge", there will be little sense from it. There are several types of batteries for these devices.

• Ni-Cd or Nickel-Cadmium Is the very first and most popular type of battery among screwdrivers. It is believed that such a battery is designed for 1,000 charges and is most suitable for home use.
• Ni-MH or Nickel Metal Hydride - slightly worse, as over time its battery capacity decreases due to frequent charging. This model is usually rated for 500 charges.
• Li-Ion or lithium-ion considered the most environmentally friendly, no harmful cadmium. The only drawback is that it does not tolerate negative temperatures well. Therefore, it must be stored carefully, preferably at room temperature. According to the characteristics, the storage temperature is declared not lower than -10 and not higher than +60 degrees.

Which one to choose for you depends on preferences and intensity of use. For home use, modern lithium is suitable.

Sparky is a quality tool

The manufacturer Sparky PROFESSIONAL is one of the leading tools in the market. It is recommended by both professionals and amateurs. The main difference between the screwdrivers of this company is the presence of a charge indicator and illumination of the work area. The varying price category among the models allows you to choose something optimal for each specific buyer. Screwdrivers are presented in several product line categories: cordless drills / screwdrivers BR2 10.8Li HD, BR2 10.8Li – C HD, BR2 7.2Li HD (where the battery type and voltage of the tool are immediately indicated), Cordless angle drill BAR 12E, cordless impact drills BUR2 18 Li HD (2/4 Ah) (battery type is also indicated).

Battery

Each Sparky model uses a lithium battery. For a long service life of a screwdriver with such a battery, there are features for its operation. Here are some tips for using a Li-Ion battery to keep it going for years.

• Monitor the charge level and charge the screwdriver at 20-30%.
• If a critical charge level of 10–20% remains on the screwdriver, this means that with subsequent charges the battery will hold the charge less efficiently, and soon it will completely disappear.
• Do not leave the battery in cold weather, in a basement or garage. These charging cells do not tolerate cold.
• Experiments have revealed that the optimal charge for storing a screwdriver should be 50-60%. If there are 2 batteries in the kit, charge one of them to 60% and leave it in the box, and use the other according to the above rules.

Despite such difficulties in operation, casting batteries are many times higher than the performance of nickel ones. Not only is it eco-friendly, it will also last twice as long. Despite the fact that lithium batteries have more capacity compared to nickel ones, when choosing, pay attention to this indicator, because the models also differ from each other.

Differences in Sparky models

Models BR2 10.8Li HD, BR2 10.8Li – C HD, BR2 7.2Li refer to cordless drills. The voltage during operation does not exceed 10.8 volts. In terms of charging time, all three models take approximately the same time - half an hour. Such models are convenient with a handle - it is much more convenient to hold a screwdriver in an upright position than it will resemble a handle in shape. All three tools come with two batteries, which makes their use even more convenient (the main thing is to use the rules for using batteries). The weight of the models is also about the same - about 1 kilogram. Thanks to this, the hand does not get tired and the process does not seem so tedious.

BUR2 18 Li HD (2/4 Ah) , in addition to two batteries, it also has an additional handle. Considering that this screwdriver has the functions of a drill, they come in handy. The model has a high torque (75 N * m) and 25 steps of its adjustment.

BAR 12E Is a cordless angle drill that allows you to work in the most difficult-to-reach places. For added convenience, the work area is illuminated with built-in LEDs. The voltage of this device is 12 volts, and the battery type is Ni-Cd.

Price category of models

The average price of a screwdriver is 5 thousand rubles. BAR 12E is more expensive - about 11 thousand rubles. If you buy a screwdriver online, there is a chance to save money, since online orders are always cheaper than those that you can buy in a store. The price is set based on the presence or absence of additional functions.

Reviews

Sparky is a quality product with good value for money. Users note that the main advantages are price, speed and drilling power, which ensures fast and high-quality work. The rubberized handle does not leave calluses and allows you to work in comfort for a long time. Keyless chuck technology saves you time when changing bits. In addition, each model has a so-called brake that stops the chuck in time. The kit most often includes a storage case and a spare battery.

The main drawbacks identified are very poor charge retention. The fact is that there is such a thing as "self-discharge", that is, in inactivity, the screwdriver also spends charging, and therefore discharges to a critical minimum. As a result, its charging performance drops.

Frequent presence of "beating" of the cartridge is noted. Buyers complain about the frequent need to recharge the screwdriver with prolonged and regular use. Also, the on / off button breaks down quickly. Under warranty, you cannot change the battery and the mains cable. There is a "life hack" here: if you register on the manufacturer's website after purchasing a screwdriver, you will receive another two years of warranty for the tool. In these models, the pros outweigh the minuses, so the Sparky screwdriver models can be recommended for domestic use.
