Review on 🔌 YONHAN Motorcycle USB Phone Charger 4.8A with Voltmeter, SAE to USB Adapter and ON/Off Switch, Dual Port Fast Charging 3 Installation Options Waterproof Quick Disconnect Plug for Smart Phone Tablet GPS by Kevin Barbon

This article will help you connect to the Sumitomo connector with 12V switch under the Ducati Monster 1200S petrol tank. However, you must first remove the tank to find the connector, and you must make an SAE pigtail with a Sumitomo connector to connect to the Ducati connector. If you can get over that, you can use this SAE USB connection (with voltmeter) to charge your iPhone on the fly. Once you have made a pigtail and connected it to the tank, you can easily use it for any 12V USB device (USB drops the voltage to 5V). Crawling under this Ducati tank is no joke, but if you're smart and don't mind cramped workspaces, it makes an excellent 12V switching power supply. I'm happy with this item!
