Easy Installation: Installing our 12V USB outlet is easy! Simply drill a 1 1/8 diameter round hole with a standard drill bit, insert the product and tighten the screw ring, connect the positive terminal of the product to the positive terminal of the power supply and the negative terminal to the negative terminal of the power supply or the override, and you're ready to start charging. Wide Compatibility: Our 12V USB outlet comes with a removable waterproof cover, making it perfect for use in harsh environments. It's compatible with all 12V-24V vehicles, including marine, ATV, motorcycle, truck, golf cart, RV, boat, and SUV. It's great for charging mobile phones, tablets, laptops, GPS, digital cameras, PDAs, and other USB accessories. Upgraded Anti-Slip Button Switch: Based on customer feedback, we've upgraded the touch switch to a more stable push button switch that is less susceptible to electromagnetic interference from surrounding electronic products. The anti-slip design makes the button easier to press. When you connect the power supply, the switch defaults to "on". So there is no need to turn it on again when you power up your car. This is very convenient. Smart Voltmeter: Our 12V USB outlet features a new voltmeter that displays real-time battery voltage when powered on without the USB cable plugged in or with only the USB-A port cable plugged in. When the USB-C port cable is plugged in, the output voltage and current of the PD port is displayed, allowing you easily to see how fast the charger is charging your device. Reliable and Durable: Our 12V USB charger is an official certified USB fast charger, equipped with a Smart Boost 65W USB PD fast charging port and an 18W QC3.0 USB A fast charging port, making it perfect for charging cell phones, tablets, laptops and other devices. The two ports can output simultaneously without affecting each other. The aluminum case is also scratch-resistant and extremely durable. Innovation and Technology: Our 12V USB outlet utilizes the latest chip technology to provide a boost function, allowing for charging of tablets at 15V and computers at 20V even when the input is only 12V (The latest boost technology pioneered by our Ouffun brand). We've also increased the length of the product for higher power and improved the aluminum texture for faster heat dissipation.
