Comparison Beurer MP 59 vs Beurer MP 55

The type of power used by the electric model (see "Type").

— Network. Powered by normal household sockets. This option is convenient because you do not have to monitor the condition of the battery / accumulator: the machine will work as long as there is voltage in the network, and the risk of being left without power at the most inopportune moment (for example, in the middle of the work process) is minimal. On the other hand, in the absence of sockets, such models become practically useless; in addition, the mains cable restricts mobility.

— Battery. Powered by an original branded battery that does not belong to standard sizes (see "Batteries" below), and in some models it is also non-removable. Like replaceable cells, batteries allow the machine to work regardless of the presence of outlets nearby; at the same time, in some moments this option is much more convenient. So, batteries are able to accumulate more energy, which has a positive effect on power and battery life; they are immediately supplied in the kit, which eliminates the additional hassle and cost of the purchase; and charging the battery is usually easier and cheaper than looking for fresh batteries. On the other hand, if there is a supply of batteries, they can be easily changed, while recharging takes time and a power source.

— Batteries. Powered by replaceable elements of a stand...ard size — for example, "finger" AA (other options may also be found). Such models, like battery ones, do not depend on sockets and can be used autonomously. The replaceable cells themselves can be produced both in the form of disposable batteries and in the form of rechargeable batteries. At the same time, both the first and second options make it easy to change dead batteries for fresh ones (the main thing is to stock up on them in advance). Of the shortcomings, it is worth noting the relatively low capacity, as well as the need for additional costs — either for the regular purchase of fresh batteries, or for rather expensive batteries. In addition, there are many batteries on the market, varying in price and performance, and the actual operating time is highly dependent on the quality of the batteries/accumulators used.

— Network / battery. Models that can work both from the network and from their own battery. The features of both types of power are described above, and their combination allows you to combine the advantages of both options and makes the machine very versatile: if you have an outlet, you can use it, and if there is no network nearby, run on battery power. The main disadvantage of such models is a slightly higher price than devices with one type of power supply.

The longest time that a self-powered electric kit (see "Type") (see above) can operate without changing batteries or recharging the battery. The higher this indicator, the more convenient the device will be in operation, the less often you will have to be distracted by its maintenance. At the same time, note that in the characteristics, the operating time is given, usually, for perfect conditions: with a minimum load on the nozzle (or even at idle), using high-quality batteries, etc. The actual time of continuous operation is highly dependent on the characteristics of the mode of use and can be noticeably less than the claimed one.

The presence of a lighting system in the design of an electrical device (see "Type"). Such a system provides additional illumination at the treatment site, which allows successful procedures to be carried out regardless of the presence of sufficiently bright external lighting. Just keep in mind that the backlight also requires electricity; this is not a problem when using mains power, however, when using a battery/accumulator, it can significantly reduce battery life.

General dimensions of the set when folded. Since most models are equipped with covers or cases (see above), in fact, the dimensions of the case / case are usually indicated at this point — tools and attachments placed inside usually do not protrude outward.

Pay attention to these data if you plan to often carry the kit with you or take it on trips.
