Specifications: Input 100~240V 50/60Hz; output 12V DC, 10A 120W max; Works well with car devices that draws less than 10A, such as 5A, 8A, 10A. Please don’t use this power adapter to power devices over 120W for a long time. Otherwise, the lifespan will be greatly shortened. Long Cable and Stable Output: With super long 13.5 feet design, enjoy convenience and flexibility wherever you need it. There is no voltage fluctuations at power on, during transmit, receive, or at power off. It will protect your electronic products from destruction. Multiple Safety Protections: All the power supplies are put through rigorous quality control procedures to ensure safe, reliable operation for years to come. Built in multiple safety protections, such as overload cut-off, over voltage cut-off, over temperature cut-off, short-circuit cut-off. Wide Compatibility: This 12v power supply works with almost all 12V under 120W automotive electronics with cigarette lighter plug, such as car refrigerator, car TV, car cleaner, car dash cam, car DVR video recorder, car Bluetooth FM transmitter, car air purifier, car humidifier, car massage cushion, car air fan, etc. 𝐏𝐫𝐞𝐜𝐚𝐮𝐭𝐢𝐨𝐧: Generally speaking, instantaneous starting current of devices with built-in motor (such as car vacuum cleaner and inflator/ air compressor ) is much higher than the rated current. So, we recommend you to buy ALITOVE 12V 15A power supply (ASIN: B08FB377WG) for 12V 8A car vacuum cleaner and inflator/ air compressor.
