・[The most powerful cooling ever in the REON POCKET series] The endothermic performance is up to 1.5 times (* 1) from the conventional one, and the cooling performance is greatly improved. The body's thermo-module has been redesigned and enlarged to achieve up to 1.8 times greater cooling efficiency * 2. * 1 When comparing the average amount of heat absorbed during the first 60 minutes of operation at the maximum cooling level between the conventional model RNP-4 and the rechargeable battery. Varies depending on usage and environment. * 2 When comparing the conventional model RNP-4 with the average amount of heat absorbed during the first 60 minutes of operation relative to the input voltage. Varies depending on usage and environment.

・[Driving time up to about 1.8 times (* 3)] The maximum cooling level COOL level 5 can be used for about 4 hours, and COOL level 4 can be used for about 7.5 hours. Longer driving times up to 1.8 times (* 4). * 3 When comparing the driving time between the conventional model RNP-4 and the rechargeable battery at COOL level 4. Varies depending on usage and environment. * 4 When comparing the noise values of the conventional model RNP-4 and COOL level 4 using our company measurement method. Varies depending on usage and environment.
