Can I use my Spark amp on battery while plugged into wall power? – Help Center

Yes. You can keep your Spark amp plugged into a wall outlet while the Spark Battery is installed — there is no need to remove the battery.

When your amp is connected to power:

The amp runs from wall power.
The Spark Battery charges at the same time, so you can play and recharge simultaneously.
Once you unplug the amp, it automatically switches to battery power with no interruption.

A full charge takes approximately 3 hours. The battery does not need to be removed for everyday use — it is designed to stay installed.

If you hear hum or noise only on battery

If your amp sounds clean when plugged into the wall but you hear a hum or buzz when running on battery, this is usually caused by:

A loose or partially inserted battery — remove and reseat the battery firmly.
An instrument cable or pickup picking up interference — try a different cable or location.

If the noise continues after reseating the battery and changing cables, please contact our support team.
