We do not recommend using the EM while it is charging.

Why is this not recommended?

• Not designed for this scenario
  The EM is not engineered to operate while being continuously connected to a power source.

• Battery safety risk
  Long-term use while charging may increase the risk of overcharging if the protection circuit degrades over time. This can potentially lead to battery swelling.

• Reduced battery lifespan
  Using the device while charging can accelerate battery wear and shorten its overall lifespan.

Recommended usage

For safe and optimal performance, we recommend:

• Fully charging the EM first

• Disconnecting the charger before use

This helps protect the battery and ensures long-term reliability.
