Max. cutting diameter
The largest diameter (thickness) of a branch that the tool can handle.
The larger the maximum cut diameter, the more powerful this model, the lower the likelihood that a certain branch will be too tough for the tool. At the same time, note that to ensure high power, long handles and strong blades are needed, which accordingly affects the dimensions, weight and price. Therefore, it is worth choosing according to this parameter with a certain margin, but at the same time, this margin should not be too large.
As for specific figures, a maximum diameter
of 20 mm or less is considered relatively small, but it often turns out to be quite enough for simple work.
21 – 30 mm — the average value,
31 – 40 mm — above average, and in loppers the maximum thickness can
exceed 40 mm.
Finger loop
The presence
of a loop for the fingers in the design of the tool. Such a loop is used in one-handed tools: it is usually installed on one of the handles, four fingers are threaded into it, opposing the thumb. Such a device provides additional convenience and reliability in holding the tool (reduces the likelihood of letting it out of hand), and also provides some protection from branches and other foreign objects.
Battery capacity
The capacity of the battery supplied with the tool.
Theoretically, the higher the capacity, the more energy the battery accumulates and the longer the tool is able to work on a single charge. In fact, however, two points must be taken into account. Firstly, only batteries with the same voltage can be directly compared in terms of capacity in ampere-hours (if there is a difference in voltage, you need to convert the capacity to watt-hours using a special formula, and use these values already). Secondly, the actual battery life will depend not only on the characteristics of the battery, but also on the power consumption of the device itself; at the same time, the power consumption for battery models is not directly indicated in the characteristics.
