Ever had your compressor turn on while using other tools and trip your customer's breaker (or your generator's)?
Even worse, ever trip a breaker when the customer is not home and you can't access the breaker panel?!
I found this adapter at Home Depot that allows you to plug up to three devices into a power strip that operates on a remote control. The remote works up to about 60 feet. Leave the door open on your van for line-of-site access and you can turn your compressor on/off remotely as you need air. $40.
