Optimum Charger for Scooter

Very compact design and small plug specially for motorcycles by BMW and other manufacturers with less than 12 Volt socket.
I use the adapter to a RT with junction box on the dashboard, where it wonderfully fits into the cockpit and hardly noticeable. When it rains, it is, however it there can not use, because the USB ports are exposed in operation and hence water can penetrate, because the waterproof cap does not help if you can connect anything, you can deduct the part of even the same. The junction box is located in a protected area, such. As under the seat, etc. It's also in bad weather. Otherwise optimal for cell phone or GPS.
