A lot of the poor quality of the ah, leakage of water leakage explosion what are the circumstances. I was 05 years in the supermarket to buy a used in the past three years. This year intends to change, but the price is not good enough to believe that the results did not find expensive. There is no purchase of electrothermal standard?
1, touch the charger, if there is a piece of things, that is electric heating wire type, if it is hard when it is small, electrode type.2, touch proof layer, good electric hot water bag is some layers.3, touch the skin, some of the better will use flannel analogues, this is relatively warm, not to burn, the surface of the material is very bad just finished the electricity is easy to cause hot to the body.So, the electric heater should be heating wire type hot water bag, right, skin layers.
Buy electric bag must have electrothermal 3CCC certification, quality system certification, inspection certificate, power line internal external insulation copper wire line are coarse as well, and then open the electrothermal cloth coat a closer look at the appearance of the work of electrothermal, and the best selection of the regular manufacturers of brand goods!
It is understood that the electrode type electric heating wire type and two kinds of electrothermal current circulation, the former prone to leakage and burst risk, relatively low in terms of security, has been included in the ban on the production and sales category. However, because the two are similar in appearance, ordinary consumers are often difficult to accurately distinguish.
