Comparison Parkside PFBS 12 C7 vs Parkside PFBS 12 C5

The number of batteries supplied with the respective tool (see "Power source"). This item may also indicate whether the tool has a built-in battery.

The most popular battery-powered kit option these days is 2 batteries. This provides additional benefits that are especially convenient for long-term continuous use of the tool. So, when one battery runs out of charge, you can quickly replace it with another; and while one battery is in use, the second can be charged. This allows you to minimize or even eliminate breaks for charging. Kits with one battery are not very common: these are mainly entry-level tools designed for small volumes of work, when breaks for charging are quite acceptable.

In addition, many modern cordless tools are supplied without batteries. This configuration assumes that the customer will purchase additional batteries at his own discretion (many models are compatible with several brands of power elements at once). In addition, this option may be useful if you already have a battery on hand. This happens quite often, since many well-known manufacturers use universal batteries suitable for different types of branded power tools. So, for example, a battery from a previously purchased jigsaw or grinder may well be compatible with an engraver or renovator from the same company.

As for non-removable batteries, this is...a rather rare and specific option. Such tools are as compact as possible, but the batteries themselves cannot be quickly changed - so during work you will inevitably have to take breaks for charging. Therefore, this power supply method is typical for low-power tools. In them, small dimensions are more important than a long period of continuous operation, in addition, low capacity allows you to achieve good autonomy even with small sizes (and, accordingly, capacity) of batteries.

The name of the battery platform supported by the device. A single battery platform is used to combine various power tools of the same brand into one line (renovator, engraver, screwdriver, grinder, circular saw, etc.). Devices on the same platform use interchangeable batteries and chargers. Thanks to this, for example, there is no need to select a battery for each individual model of a power tool, because one purchased as a spare battery can be used in various power tools, depending on the situation or as needed. Batteries of the same platform basically differ from each other except perhaps in capacity.

A device for charging the batteries used in the tool with the appropriate power supply. For models supplied with such a device, the charger model may be additionally specified in the characteristics. This information can be useful not only for finding a spare or replacement charger, but also in case the household has other cordless tools and / or batteries for them. The fact is that many manufacturers nowadays use universal batteries that are compatible with a whole set of tools from the same brand; so, for example, a complete charger may be quite suitable for a cordless grinder or drill from the same manufacturer.
On the other hand, a lot of modern cordless tools come without a charger at all. This option will be optimal, first of all, if a compatible memory is already available, and there is simply no need to overpay for a second device. In addition, the lack of a charger will be appreciated by those who want to choose this accessory separately, without relying on the manufacturer's decision.

The noise level produced by the tool during operation. For comparison, 50 decibels roughly corresponds to the noise in an office room, 60 dB to an average TV volume, 70 dB to a truck at a distance of about 8 m, 80 dB to traffic noise, 90 dB to a loud scream.

The lower the noise level, the more comfortable the use of the tool. At the same time, note that this parameter is usually indicated very approximately — the actual “loudness” of operation can vary markedly depending on the mode, the nozzle used, the material being processed, etc.

The weight of the tool can be indicated according to different rules: some manufacturers take into account only the body without a nozzle, others — with a standard working nozzle, for multi-tools (see "Device") the weight of the main unit without a replaceable head, etc. can be indicated. These points are usually specified in the specifications or detailed documentation.

In the case of a power tool, weight has a dual meaning. On the one hand, the smaller it is, the easier it is to hold the unit in your hands during long work and the more convenient it is to carry out fine, accurate processing. On the other hand, a light tool is less stable and has an increased tendency to jerk, which is important under difficult conditions and hard materials.
