Smart power distribution module
It makes fitting aftermarket accessories a doddle, just connect the 2 ring terminals to your battery. The ThunderBox 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, and that’s it!
The 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.
