Comparison Kraissmann 2001 AMS 42 vs Parkside PFBS 12 C5

The total number of working attachments supplied with the tool.

The abundance of attachments allows the machine to be used with various materials and for various types of work. At the same time, this parameter significantly affects the cost. Therefore, when choosing, you need to proceed from how important a variety of possibilities is for you - so as not to overpay for extra nozzles that turned out to be useless in fact.

Note that this item is indicated only for engravers (see "Device") - for models of other types, specific types of nozzles are given in the corresponding item (see below).

Nominal voltage of the battery supplied with the appropriately powered tool (see above).

This parameter is usually selected by the manufacturer in such a way as to optimally match the specifications of a particular model. Therefore, in fact, it is more of a reference than really meaningful. However, in some cases, voltage information can be useful — for example, if you are looking for a spare battery or want to replace a failed battery.

The capacity of the battery that the tool with the corresponding type of power is equipped with (see above).

Capacity is essentially the amount of energy a battery can store. The more powerful the device, the more energy it needs to work and the higher the battery capacity should be so that it does not have to be charged too often. At the same time, capacious batteries have a large weight and dimensions, which significantly affects the convenience of work. Therefore, the power of the battery tool is relatively low — otherwise, too bulky batteries would have to be used.

To some extent, this parameter also determines the time that the tool is able to work without recharging. However, taking into account the fact that different models can noticeably differ in power consumption, it makes sense to compare with each other by battery properties only tools with very similar specifications — and even then very approximately.

Note that the same tool can work with batteries of different capacities — it is enough that they are compatible in terms of connectors and operating voltage. However, if you are looking for a spare battery or a replacement for a failed battery, it is best to choose a variant of the same capacity as the original one.

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.
