The ThunderBox is an advanced power distribution module, which simplifies and safeguards the process of connecting aftermarket electronic accessories (such as extra running lights, heated grips, GPS, phone charger, extra gauges and any other powered devices) to your vehicle. The TB not only extends battery life, but protects the bike’s electric system from overloading and short circuits.
A weatherproof USB charger is available separately (part no.: TB-USB1). You may connect multiple USB chargers to one TB unit.
