[Sealing Structure,Safe to Use]:Single-layer double-sided ceramic structure,alloy semiconductor material inside,can directly convert thermal energy into electrical energy. [High Reliability and No Pollution]:Red wire to positive,black wire to the negative, it generate electricity when the temperature difference happened. [Connection ]:In practical applications, in order to higer output voltage and load current, multi-parallel-parallel combination is adopted. [Color-Coded Leads For Identification]:Cable length is 14cm/ 5.5inch,red(+)and black(-),color-coded leads for identification of polarity. [Light Weight, ]:Small size (40x40mm/1.6inch )and light weight, convenient for use. Colour:White Material:Bismuth telluride Package Contents: 1 x thermoelectric generator(different batches Random fonts, don't accept the specified) Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
