How long will a 8 kwh run a 300w speaker?

The 300 W speaker will run for, t = 26.67 h

Explanation:

Given data,

The power storage, p = 8 kWh

= 8000 Wh

The power of the speaker, P = 300 watts

It means the speaker consumes 300 watts of power in an hour.

Therefore, with 8000 Wh, the speaker will last around,

t = p / P

= 8000 / 300

= 26.67 h

Hence, the 300 W speaker will run for, t = 26.67 h
