Installing an ETC does not require a power source. Current ETC devices come with their own power supply, typically with a battery lifespan of 3 to 5 years. New OBUs feature solar panels that can recharge using solar energy, eliminating the need to connect to the vehicle's power supply. ETC installation position requirements: Height should not be less than 1.2 meters or exceed 2.5 meters; installation angle N should be between 30º and 90º (the angle between the electronic tag surface and the horizontal plane). The ETC installation process is as follows: Upon receiving the device, first check if the ETC card and electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU, and a red light will briefly illuminate. The OLED screen will display "Tag Invalid" and "Please Insert Card," indicating the device is functioning normally. Clean the front windshield, ensuring the glass surface is smooth, clean, and dry. Then peel off the adhesive backing on the OBU and attach it to the installation position. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front facing the driver and the back facing the windshield, ensuring the chip is inserted into the OBU device.

As a seasoned driver, I've installed quite a few ETC devices, and they indeed require electricity. That gadget is an electronic device, just like how a phone needs charging. During installation, it either plugs directly into the car's OBD port for power or relies on the cigarette lighter or USB port to charge. Some have built-in rechargeable small batteries that get topped up while driving, but if parked for more than a few weeks, they might drain and need recharging. When I first installed mine, I found a loose connection caused it to malfunction, but after reinforcing it, it worked fine. Overall, the power consumption is very low and doesn't affect fuel efficiency, zipping through toll stations saves time and hassle. Remember to regularly check the device's status to avoid unexpected power loss. In summary, electricity is a must, don't find it troublesome, daily use is completely hassle-free.

I enjoy delving into car accessories, and the ETC device definitely requires power. It operates via radio frequency signals to send and receive data—without electricity, it's as useless as a brick. There are various installation methods: some connect to the car's power system, like the fuse box; others come with built-in lithium batteries that can be recharged or replaced. I use my car frequently and have never run out of power, but during long-term parking, I need to manually turn it on for a check. Power consumption is minimal, costing just a few cents per month. Installation isn't difficult and can be a DIY project, but ensure voltage compatibility to avoid short circuits. Regular maintenance can extend the device's lifespan—keep impurities out of the interfaces. Power supply is the foundation; without it, all smart features become non-functional.

I'm a new car owner and just had an ETC installed. The staff told me it requires power and can be plugged into the small round socket in the car. It powers itself while driving and relies on a small internal battery when parked, which usually doesn't run out. The installation process was super simple, taking just a few minutes without needing an extra charger. Driving through toll stations has saved me a lot of time, and I haven't had to worry about power issues at all. Just remember to occasionally check if the device's light is on to ensure it's working properly. Don't worry about it consuming much power—it barely affects the car battery.
