Fig.1: the PowerUp works by detecting the current flow through the master mains outlet and then switching power to slave outlet.

YOU CAN ALSO USE PowerUp in your workshop. Switch on your router or bench saw and the vacuum cleaner will suck away the sawdust straightaway. Doubtless there are other applications to save you switching on numerous other items of equipment when you want to get straight into work or play.

The PowerUp connects to the main unit such as an amplifier and switches on power to the remaining units whenever the main unit is switched on. This saves having to power up the other units separately.

PowerUp is a small box with two mains outlets, one for the master appliance and the other to run the slave appliances. This second outlet would provide power to a multi-way power-board for the remaining appliances. When the master appliance is switched on, the other appliances will be powered up also.
