This is a USB boost cord that can be used with Mitsubishi Electric's integrated antenna ETC on-board units (models EP-9U53V, 56V, 57V, 58V, 59V, 512V, and models without a V at the end). Although we have not been able to confirm everything, the EP-9U series, which is an antenna-separated type made by Mitsubishi Electric, appears to be the same model. Please note that this product cannot be used with Mitsubishi Heavy Industries onboard units. Boosts USB standard 5V to 12V to drive the ETC onboard unit. Simply plug the USB terminal into your car or a mobile battery for your smartphone, and the on-board unit will operate. The cord is approximately 100cm long, and on the opposite side of the USB A terminal, it has a fixed JST connector (BEC connector), lead wire, and a coupler for Mitsubishi Electric on-board units. The USB boost cord is thin and can easily break if directly connected to the Mitsubishi Electric in-car device coupler, so it has been processed into a shape that requires more effort compared to cords for other companies. ※ The length and specifications of the lead wire may vary slightly depending on the production period. ※ Price negotiation is not possible for this item. ※ Purchase without comment is welcome. ※ The in-car device, mobile battery, and ETC card shown in the photo are for demonstrating operation and are not included in the product.
