Kawasaki H2 SX SE comes factory-equipped with a built-in cigarette lighter socket, which isn’t very practical. I used a cigarette lighter USB adapter for a while, but that solution wasn’t ideal, mainly because it offered no protection against rain. So, I decided to install a built-in USB charger to replace the stock lighter socket.
In the first two photos, you can see the original cigarette lighter socket as well as all the materials needed for the new setup. Unfortunately, the USB charger’s diameter is about 1 mm larger than the original socket, so I had to slightly widen the hole with a file. However, I used a new power connector identical to the factory one, which means I didn’t have to cut or damage any of the motorcycle’s wiring — I simply connected the USB charger to the existing connector.
I checked which wire was positive and which was negative, labeled the terminals, and completed the wiring and installation. The USB charger was purchased from AliExpress and is supposedly rated at 83 W total output — 65 W from the USB-C port and 18 W from the USB-A port. Honestly, this is how the motorcycle should have come from the factory, not with an outdated cigarette lighter socket.
