|Physical Cooling Apparatus||Wet towel||Ice bag|
1) With 3 kinds of functions,cooling, keeping constant temperature
and temperature controling;
2) Drop to 15℃ in 10 minutes;
3) The temperature can be set between 12~38℃ by yourself ;
4) Keep constant temperature continuously.
|Pre-cool ahead every time,unable to keep constant temperature.The
temperature of wet towel is depends on hand's feeling and cooling
time is very short.||Same as wet towel, the period is longer than wet towel's cooling.|
1) Materials: non-toxic , non-irritating , non-allergenic ;
2) Parts:safe and environmentally ;
3) Voltage :safety enough below DC 9.0V;
4) Waterproof , moistureproof;
5) Life: 20,000 hours (over 5 years)
|Safe.||Safe. But the ice bag is too cold when it is taken out of
1) Small size,and the host weight is only 123g with flexible belt;
2) It can be used repeatedly more than 2000 times
(10 hours per time).
|Unconvenient due to changing towel always.||Pre-cooled in the refrigerator ahead,unable to work continuously.|
|Secondary effects||Keep constant temperature continuously, More heat can be taken away
faster.||Unalbe to keep constant temperature, the effect is slower.|
Unable to keep constant temperature. The effect is slower.
