Input adapter: AC 100V~240V 0.25A 50/60Hz, Adapter output: 3V/4.5V/5V/6V/7.5V/9V/12V.; Maximum output current: 2A. A USB 5.0V 2.1A port, perfect for USB charging of smartphones and other devices, cable length is 115 cm. Compatible devices DC 12V-2A or 12V-1.5A. 6 detachable DC output plugs make it suitable for 95% of AC/DC devices, such as 3V to 12V household appliances, Tablet PC, Scales, Routers, Speakers, LED strip Lights, CCTV camera systems, USB charging camera, Smartphones and so on. The power supply meets international standards such as ECO-design, CEC and MEPS. Therefore, standby losses are significantly reduced, which ultimately contributes to a reduction in CO² emissions. NOTE: 1. NOT compatible with laptop or other high-power equipment, i.e. NOT compatible with devices over 30W and the polarity cannot be reversed. 2. DC plug polarity: Internal positive (+), External negative (-). The charger has two output ports: a coaxial port and a USB port: When using only the coaxial port, the maximum voltage is 12V and the maximum current is 2A, so the maximum power for the coaxial port is 24W. When using only the USB port, the maximum voltage is 5V and the maximum current is 2.1A, so the maximum power for the USB port is 10.5W. In addition, both ports can be used together. When using both ports together, the sum of the power can reach 30W. With 6 adapter plugs: - 2.5 x 0.7 mm plugs; - 3.0 x 1.1 mm plugs; - 3.5 x 1.35 mm DC plugs; - 3.5 x 1.5 mm DC plug; - 5.5 x 2.5 mm DC plug; - 5.0 x 2.1 mm DC plug.
