Stop Wasting Money On Dirty, Unstable Electricity
Official New Zealand Store. For a limited time, save up to 65% on the plug-in electricity stabiliser that reduces dirty power and lowers your energy bill.
Why Your Power Bills Keep Rising
New Zealand households are paying some of the highest electricity rates in the world — and a significant portion of what you pay for is wasted to voltage instability, dirty electricity and power surges that your utility bills you for anyway.
Unstable current forces your appliances to draw more power than they need, generating excess heat and wearing out faster. That inefficiency compounds every month on your bill.
How StopWatt Fixes It
StopWatt uses Electricity Stabilizing Technology (E.S.T.) to deliver clean, stable power to every outlet in your home. It works immediately upon plugging in, confirmed by the green indicator light.
The result is lower power consumption at the meter, reduced dirty EMF electricity throughout your home and real savings on your next bill.
Four Ways StopWatt Improves Your Home's Electricity
- Stabilizes Electrical Current: Smooths unstable grid power into a constant, efficient output for your appliances.
- Eliminates Harmful Surges: Advanced capacitors absorb voltage spikes before they damage your devices.
- Reduces Dirty EMF Electricity: A magnetic filter reduces your home's exposure to harmful electromagnetic radiation.
