Warm to soft: test 7 heated seat covers
Unlike the mug that my favorite poet was looking for on a winter evening, the containers described below are for drinking warm drinks. But these are not boilers and not mini-kettles, but only heaters connected to a 12V car socket. Their power is relatively small, and therefore they are unsuitable for boiling. However, the temperature must be maintained.
Four electric mugs for the test. Prices - from 500 to 1950 rubles. All made in China, although the name "Pathfinder" alludes to Russian roots.
Manufacturers advertise the capabilities of their products in different ways: someone puts the useful volume in the first place, and someone indicates the length of the cord and the maximum allowable working time.
We go for water. Let us evaluate how quickly these devices raise the temperature of the liquid from the initial +20 ºС and how high. Of course, we’ll check whether it’s convenient to use them.
The use of a high-frequency connector is surprising. Really in China there was no normal connector? And it’s really bad that the power is supplied through the plug connector: any accidental touch of metal - and hello to the fuse. "Plus" and "minus" are not protected by anything!

We tested at a supply voltage of 14.2 V. The Koto 12V 272 mug consumed the least. The current was 2 A. The Naturalist was the most voracious - 3.8 A. It is not surprising that he turned out to be the most agile: after 25 minutes, the water temperature rose to 60 ºС (the built-in thermometer at the same time showed 65 ºС). Then the agility was clearly reduced: over the next 25 minutes, the temperature increased only to 70 ºС. Well, about this was promised.
For an hour of operation, Koto 12V 272 reached 61 ºС, the Yasha TH100 mug reached 68 ºС. And the Pathfinder PF-CWS-P20 even overcame the 70 degree mark. True, the liquid is placed a little less than the rest of the circles. Perhaps that is why the result is better.
A modern device without a display is not good, even if we are talking about a regular mug. Even worse is the following: if you take the container in your right hand (what else, if the car is left-hand drive?) And try to take a sip, then part of the contents will spill just onto the “brains” of the device. A modern device without a display is not good, even if we are talking about a regular mug.

Why doesn't the temperature rise further? Presumably, the heat transfer of the mugs, which equaled the size of the supplied joules, affects this boundary. However, no one promised to boil water: you just need to keep in mind that you cannot make coffee from raw water in such a mug.
We decided not to put the products in their places: the difference between them turned out to be insignificant. Our opinion? Such a mug under the New Year tree will come in handy - not all gifts will be useless.
Koto 12V-272, China. Thermo mug with electric heating function Koto 12V-272, China. Thermo mug with electric heating function The approximate price of 1200 rubles. Volume 450 ml Power Consumption 2 A Cord Length 1.2m The promised heating mode to 75 ºС in 20 minutes Maximum working time 6 hours The actual capacity is 400 ml: do not fill it to the eyeballs. The consumed current is 2 A. This is the most low-power device in our sample. In about an hour, the mug warmed up room temperature water to 60 ºС. |
Yasha TH100, China. Thermomug electric automobile Yasha TH100, China. Thermomug electric automobile The approximate price of 1500 rubles. 420 ml volume Current consumption not specified Cord Length Not Specified The promised heating mode is not specified Maximum duration not specified The water consumption of 400 ml consumed a current of 2.3 A heated in an hour to 68 ºС. The disadvantage is the alien high-frequency connector with a current-carrying plug: it does not belong here. Why is this connector bad? Mainly, by the fact that it can pass on any metal object, for example, on a button or coin. And the general impression of the design is so-so: they were blinded from what was. |
"Naturalist", China. Car mug heated by a cigarette lighter "Naturalist", China. Cigarette Lighter Heated Car Mug The approximate price of 1950 rubles. Volume 450 ml Current consumption not specified Cord Length Not Specified Promised heating mode to 72 ºС Maximum duration not specified The most “smart” mug in our selection. The built-in indicator shows the temperature of the liquid (its actual volume is approximately 420 ml). The button allows you to set the desired temperature. The consumed current is 3.8 A. In 25 minutes, the water heats up to 60 ºС, and in the next 25 minutes - up to 70 ºС. Again, the connector type "tulip" is clearly from someone else's shoulder. |
The Pathfinder PF-CWS-P20, China-Russia. Autoscale Pathfinder PF-CWS-P20, China-Russia. Car mug The approximate price of 550 rubles. Volume not specified Current consumption not specified Cord Length Not Specified Promised heating mode to 72 ºС Maximum duration not specified The cheapest item in our selection. Holds approximately 380 ml of liquid. For an hour at a current of 2.3 A, water was heated to 70 ºС. |
