[Upgraded Version]: We have developed an upgrade plan for this 12V 3A power adapter: a switch device is added to the power cord to achieve one - key power on/off. This is more convenient, reduces the number of power plug - ins and unplug - ins, and effectively improves safety performance. The cable extended to 6.5 feet can meet the needs of longer - distance use. [Power Specifications]: Input: 100V - 240V 50/60Hz; Output: 12V 3A, 2A, 1.5A, 1A, 0.5A. The output adapter has an adaptive cylindrical plug size of 5.5mm x 2.5mm (suitable for 2.1mm), with the center positive (+). In addition, it is equipped with a DC female connector, and the wires can be easily tightened without soldering. You can design your own adapter projects for more household electronic products below 12V 36W. [Wide Compatibility]: This power supply is almost compatible with all 12V DC small - sized devices, such as LED light strips, wireless routers, ADSL modems, Bluetooth speakers, GPS, webcams, digital piano keyboards, switches, CCTV surveillance cameras, and other devices powered by 12V DC (3A, 2A, 1.5A, 1A, 800mA, 500mA, 400mA, 200mA, 100mA) power supplies. [Safety Protection]: Automatic overload cut - off, over - voltage cut - off, over - temperature cut - off, short - circuit cut - off. The sufficient 36W output power and stable 12V output voltage will protect your electronic devices from damage. [Special Notice]: This product is a 12V DC power adapter, not a charger. It is not compatible with laptops, massagers, vacuum cleaners, or blood pressure monitors. It is also not compatible with Anker hubs, robot vacuums, network video recorder connectors, scanners, and some LED lights. Please confirm carefully before purchasing. [After - sales Service]: If the product you received is defective or has any other problems, please contact our after - sales team for help via (private message). We will handle it for you within 24 hours. Thank you in advance! We hope to provide you with better service.
