Einhell Twincharger – 3A Dual Power X Change Smart Charger

The Einhell twincharger is designed to charge two 18 V Power X‑Change batteries in parallel, making it perfect for charging 36 V equipment such as the FLUX FBM 4100 cordless pump motor. With the ability to replenish two batteries at once, you can get back to work without delay. Plus, charging cycles adapt to the battery’s condition, which helps prolong service life and maintain long-term performance.

Furthermore, intelligent charging management monitors each battery throughout the process, delivering the right amount of power at the right time. This helps extend battery lifespan while maintaining fast charging speeds. In addition, the 6‑stage LED display provides clear, instant updates on each battery’s status.

Einhell charger – smart, safe and built for everyday use

The charger includes a refresh mode that can revive deeply discharged batteries, helping restore performance and extend their usable life. This is especially useful for batteries that haven’t been used for long periods.

Moreover, safety is prioritised through continuous monitoring, protecting against overheating, overcharging and voltage fluctuations. In addition, integrated hanging slots allow for simple wall mounting, keeping your workspace tidy and your charger accessible.

As a universal Einhell charger, it works with every Power X‑Change battery.

• Parallel charging keeps your pump or tools powered and reduces waiting time.
• Smart charging protection ensures safe, efficient charging and helps extend battery life.
• Refresh mode revives deeply discharged batteries, improving long‑term performance and reliability.

Can the twincharger handle two different battery sizes at the same time?

Yes. You can charge any combination of Power X‑Change batteries – from compact 2 Ah units to high‑capacity Multi‑Ah models – without affecting charging performance.

Does charging two batteries together slow down the process?

No. Each slot delivers a full 3 A charging current, so both batteries charge efficiently and independently.

Is the twincharger useful if I only own one battery?

Absolutely. It works perfectly with a single battery and gives you room to expand your cordless setup in the future.
