※【Conditions for batteries that can be used】

1. Mobile battery compatible with USB PD (PD is a USB standard and an abbreviation for Power Delivery)
2. USB output voltage is DC20V or higher
3. USB output amperes must be 3A or more.

Note: This product will not work with batteries with an output of less than 20V.

The amplifier's output, sound quality, and usable time will vary depending on the battery specifications. With 3A types, the volume and sound quality will be lower than with AC power.

We do not guarantee that the amplifier can be used with all batteries. With some batteries, the protection circuit may trip and shut down the amplifier if the input/output is too high.
