Campagnolo EPS Charger

Campagnolo EPS charger: essential for your electronic transmission

In the world of high-end road cycling, Campagnolo EPS (Electronic Power Shift) represents the pinnacle of electronic drivetrain technology. But to truly unlock its performance, one often overlooked component is key: the Campagnolo EPS charger. Small in size but critical in function, this charger ensures the autonomy and reliability of your Campagnolo electronic groupset.

What is the Campagnolo EPS charger for ?

The Campagnolo EPS charger is designed to recharge the internal battery of the electronic shifting system. Compatible with EPS 11- and 12-speed groupsets (Record, Super Record, Chorus), the charger powers the front and rear electronic derailleurs as well as the shifters.

Unlike traditional mechanical drivetrains, Campagnolo EPS systems require a constant power source to operate. That’s why the EPS V4 or V3 charger (depending on your setup) becomes a must-have for any rider using a Campagnolo electronic system.

Technical features of the Campagnolo EPS charger

The EPS charger stands out for its reliability and ease of use. Here are the main specifications:

• Compatibility: EPS V2, V3, or V4 systems (depending on the charger model)

• Quick-connect: magnetic or micro-connector port

• LED charge indicator: displays battery and charging status

• Full charge time: approximately 1.5 to 2 hours

• Voltage input: 110–240V AC

• USB or wall outlet cable depending on version

Some models include the DTI (Digital Tech Intelligence) interface, which acts as the brain of the EPS system. It coordinates communication between components, manages gear changes, and monitors the battery status in real time.

Why is it essential for your Campagnolo electronic derailleur ?

A fully charged EPS system ensures smooth, silent, and instantaneous gear shifts, even under heavy load or on steep climbs. With the Campagnolo electronic drivetrain, every touch of the shifter triggers a precise command to the motorized derailleurs. Without enough power, the system can fail mid-ride, compromising both performance and safety.

The EPS charger is therefore essential for:

• Extending the lifespan of the integrated lithium-ion battery

• Preventing unexpected drivetrain shutdowns

• Maintaining optimal performance on every ride

Best practices for using the Campagnolo EPS charger

• Charge regularly, even when the bike is not in use — the battery slowly discharges over time.

• Store the charger in a dry, temperature-controlled environment.

• Check compatibility with your EPS generation (V2, V3, or V4) before purchasing.

• Avoid overcharging — unplug once the battery is full.

Final thoughts

The Campagnolo EPS charger is far more than a simple accessory — it’s the cornerstone of your Campagnolo electronic drivetrain. It powers the system, supports the responsiveness of the electronic front derailleur, ensures the accuracy of the rear motorized derailleur, and keeps shifting crisp and seamless.

If you’ve invested in an EPS groupset, make sure you always have a compatible, working charger on hand. A properly powered electronic system turns every ride into a smooth, intuitive experience.
