No. Using the EM while charging is not recommended, as it may affect battery safety and lifespan.
For best performance, fully charge the EM first, then disconnect the charger before use.
See battery safety details in our Help Center.
A small difference between EM readings and mechanical pressure gauges is normal and within operating tolerance.
Mechanical gauges typically allow ±0.3 bar, while the BOOKOO EM measures within ±0.1 bar, resulting in a possible combined deviation of up to ±0.4 bar.
This does not indicate a malfunction if extraction behavior remains normal.
