Efergy Plug-in Power Meter

 

This plug-in power meter from Efergy may not have as many features as some of the more expensive models, but it is usually found at a very reasonable price and covers all the basics. It can easily show you amongst other things: how much electricity the plugged-in appliance is consuming in Watts / KiloWatts, how much this costs per hour, the supply voltage at your home and how much electricity the connected appliance has used over time in kWh or pence.

  • Working voltage: 90-250VAC @ 50-60Hz
  • Power range: 0.2 - 3120 Watts
  • Current range: 0 - 13.00 Amps
  • Voltage range: 90 - 250 Volts
  • Cost per unit: 0.00 - 99.99 £/kWh

It's worth pointing out that in common with most budget plug-in monitors, this one has no battery backup, so you have to remember to take your readings before unplugging it.
