| + | [* black] Time (hours) = Battery Capacity (mAh) / Current (mA) |
| + | [* black] Standard 9V D battery capacity: 565mAh |
| + | [* black] Average music listening volume current draw: 25mAHow |
| + | [* black] 22.6 Hours = 565mAh/24mA |
| + | [* black] It is worth powering with wire and not battery if using the Crush Mini as an office speaker. However, most inexpensive switching-type power supplies are noisy, and that can be heard through the amplifier. I am able to use a benchtop switching power supply with a lower noise floor, and that is tolerable, but not a permanent solution. |
