Fast heating
The presence of a
fast heating mode in the device. In this mode, the heating element operates at increased power, thereby reducing the time required to reach operating temperature. After entering the mode, the heater power usually decreases automatically, but this point needs to be specified separately. Also note that auto switch-off of fast heating and auto-switch of power level are different functions, see below for the last.
Auto switch-off
The ability
to automatically turn off the heater after a certain time.
Auto switch-off performs three main functions. Firstly, it provides safety: even if the user forgets to turn off the heating pad, it will not overheat and cause a fire. Secondly, the overheating of the user himself is thus prevented; this is especially convenient if the heating pad is used during sleep. Thirdly, auto switch-off allows you to avoid unnecessary power consumption.
Note that the response time and features of its adjustment may be different. So, in the simplest models, only one option is provided (for example, after 90 minutes), more advanced devices may have
several time settings or even the ability to set it yourself within a certain range.
Operating time
The operating time is the time until the device auto-shutdown. Therefore the time during which a sheet or blanket works on heating. There are models with an adjustable shutdown timer, which allows you to set the required time for the device to automatically turn off.
Cable length
The length of the cable for connecting to the mains, which is equipped with a heating pad.
On the one hand, the longer the wire, the easier it is to connect the device to the outlet, the lower the chance that an extension cord will be needed for this. On the other hand, a long cable can get tangled and create inconvenience. Thus, in most heating pads, the length of the wire is about 2 – 2.5 m — a longer length is rarely required and in such cases it is usually not a problem to find an extension cord.
