Smart power distribution module
It makes fitting aftermarket accessories a doddle, just connect the 2 ring terminals to your battery. TheThunderBox automatically detects when your engine is running/charging and switches power on to your accessories then switches off when the engine is stopped.
Connecting accessories to ThunderBox is even easier with piano key style locking connectors, just lift the orange tab, insert the wire from your accessory & press it back down, that’s it!
Optional extra USB port is available (part no.: TB-USB1, output: 5V/2A).
You may connect multiple USB chargers to one TB unit.
Wide compatibility
Compatible with ALL vehicles using a 12V battery system (all battery types and capacities are supported), including all motorcycles, cars, ATVs/UTVs, kit cars and even lawnmower trucks.
How it works
The TB constantly monitors the battery voltage, engine state (running/off) and the outputs, then switches the loads on/off automatically. The TB isolates/disables the power supply to the accessories until the engine is started and running smoothly, ensuring 100% battery power is always available for starting. This is a fully automated process, resulting in trouble-free starts and enhanced battery life.
