Kill-a-Watt we looked at the plug-in electricity usage monitor of that name. Still not available for the UK market, we also introduced a
UK Power Meter which does the same job - displaying how much power any appliance plugged into it is using.
New from
P3 International is the
Kill a Watt PS (P4320) - an electricity usage monitoring
power strip (pictured above). This new product offers a selection of advanced features designed to
protect expensive electronic equipment at the same time as
measuring its power usage.
Power Strip Features
The
power strip offers 8 outlets in total - 6 of standard width, and 2 extra wide outlets to enable mains transformers to be plugged in (for use with mobile phones, battery chargers, and so on). The power strip is fitted with a 2 metre (6 feet) long cable and a low profile plug.
To protect senstive electronics from
voltage spikes when they are plugged in, a spike-free ON/OFF switch offering
soft power-up is integrated in the Kill-a-Watt PS. Advanced
surge protection circuitry is coupled with an
EMI (electro-magnetic interference) filter to ensure that only clean, safe power gets to your appliances. Over-current, over-voltage, and over-load detection gives further protection.
A
Max Amps switch enables the user to set the maximum current which the appliances plugged into it can draw - 2A, 5A, 10A, or (by default) 15A. If the plugged in appliances attempt to draw more current than the
Max Amps settings, an electronic fuse breaker (NFB) will cut power to all of the outlets.
The power strip can be wall mounted (using 2 no. 8 sized screws).
Electricity Usage Monitoring Features
The
Kill-a-Watt PS tracks 8 key measurements - voltage, line frequency, current,
active power, power factor, cumulative kWh, current leakage, and elapsed time. It will also calculate the cumulative
cost of the electicity used since your last reset, and forecast the cost per day, week, month, and year of electricity at current usage levels.
If you remove power from the
Kill-a-Watt PS, all accumulated measurements (kWh and elapsed time) will be stored in
memory ready to be added to when the unit is plugged back in again. At that time, the display flashes to indicate that there has been a power interruption - useful to know in the event of a brief power cut.
Buying the Kill-a-Watt PS
The
Kill-a-Watt PS (P4320) is available online in the USA for just under US$100. As with the standard Kill-a-Watt, the maximum input
voltage
is 120 VAC (for the US 110 VAC mains supply)
- therefore, this product cannot be used in the UK, Europe, Australia, NZ, Far East etc.
However, a standard 240VAC rated
UK Power Meter (<£20) can be used in conjunction with a good quality standard surge-protection power strip / extension cable (<£20) to emulate most of the functionality of the
P4320.
