Questions about this item

How often will the 1800mAh battery need recharging during a full teaching day?

The 1800mAh battery delivers 8 to 10 hours of continuous use on a full charge, so a single overnight charge covers most full-day schedules.

What limits the amplifier first when I run it at the 10W output for hours?

The 1800mAh battery runtime of 8 to 10 hours is the first limit; the 10W output stays steady until the battery depletes.

Does the 200-gram amplifier get hot or noisy after hours of daily use?

No fan or active cooling is mentioned, so the unit runs silently and stays cool during extended operation.
