Ambient Humidity: 5~95% Non-Condensation Weight: 0.7 lb / 325g Package included 1x 72W Universal Power Supply Adapter; 14x DC Tips; 1x Reverse Polarity Converter Cable Attention: The power cord between power brick and DC plug will lead to 0.4V~0.6V voltage drop, so we designed the screen displayed voltage was 3.5V~24.5V. Only in this way can your device really get 3V~24V voltage. This is the reason why we advertise the power supply's voltage range is 3V~24V, not 3.5V~24.5V. Caution: The 17.cm short black power cord is a reverse polarity converter, not extension wire. It is used to reverse the original polarity of the power supply output port ( reverse the internal positive pole to negative , and the external negative pole to positive). Please confirm the polarity of your devices’ power port before use. If the positive and negative poles are reversed, it will cause short circuit and damage your device.
