This North American standard AC cable plus directly into your Campagnolo EPS Power Unit Charger to recharge the Lithium Ion battery of the EPS system in your bike. These are not included with the unit because Campy makes several different types of plugs to fit the wall socket in your region. The cable you see here is for the US Standard and fits any sockets in North America. If you are planning to travel abroad with your EPS unit, you may consider purchasing a different Power Unit cable that will be compatible to where you are traveling.
