250 Megawatts = 250,000,000 Watts.
100 watts is great, 150 watts may be too loud for some, and there is higher watt amplifiers made.
Depends on the voltage. AMPS X VOLTS = WATTS 250 Watts at 12 V would be about 21 Amps, while 250 watts at 120 volts would be 2.1 amps.
No, you cannot always get 250 watts of power out of a mechanical system when 250 watts of power is input. Some energy may be lost due to friction, heat, or other inefficiencies in the system, resulting in a lower power output.

250 Watts.
1000 watts is not twice as loud as 500 watts, that is the first myth to break. But 1000 watts will sound superior because of something called headroom. The best way to think of it is in relation to room size. 1000 watts will not rock Glastonbury but it will do serious damage in a pub or medium to large hall.
How loud or how many watts it has.
A 30 amp circuit on a 250 volt service could handle up to 7500 watts. That's if it's actually 250 volts coming in. You should check that with your meter.
The newer PS3 slim models consume 250 watts for all HDD sizes
The power consumption of a KitchenAid mixer is typically around 250-300 watts.
+- 250 watt to 500 watt
