Thunderbox – Power distribution unit for accessories
Thunderbox – Power Distributor for Accessories. Tired of doing makeshift electrical installations on your motorcycle? We have the solution. The Thunderbox is an electronic box designed to connect directly to the battery's positive terminal and charge or power 5 or 10 different devices (depending on the 16A or 32A version) ONLY when the vehicle is running. Yes, you read that right, this device acts as an electronic relay, operating only when the motorcycle is running. Being electronic, it also self-manages overloads and cuts power like a fuse if it detects any fault. There are two Thunderbox models: the 16 Amp version with 5 power outlets and the 32 Amp version with 10 power outlets.

Our opinion
Honestly, we only recently discovered this product and we already love it. With the Thunderbox, you don't need extensive electrical knowledge, just the basics to connect it. Its main advantage for us is the savings in cable, space, and weight on the motorcycle. It's highly recommended for installing accessories such as heated grips, USB socketA car charger, auxiliary lights, or whatever else you can think of. This single, very small unit saves you from installing a fuse box, a relay, a lot of wire, soldering, and electrical tape.
