Volts x Amps = Watts -or- Amps = Watts / Volts.

150 Watts / 120 Volts = 1.25 Amps. So, you can run an applicance that draws less than 1.25 amps. But that's if the inverter is rated for 150W continuous use. I don't know if this one is.

But there's more... the battery can only provide 6 Amp hours according to the listing on Home Depot's site. Using the same formula for the battery side of the inverter:

Amps = Watts / Volts -or- 150 Watts / 18 Volts = 8.3 Amps. You would be drawing 8.3 Amps from the battery which can deliver 6 Amps for 1 hour. Your setup should last for about 45 minutes.

Keep in mind that manufacurer's ratings often leave out some real world stuff so your real world results are more likely to be about half of that.
