Why buyers choose the official store

Straight facts, then a risk-free test

Plug in, that's it

No wiring, no electrician, no app. Insert into any standard grounded outlet and the indicator light confirms it is working.

Targets motor-driven loads

Internal capacitors supply part of the reactive current used by pumps, compressors, fans and HVAC motors.

No inflated promises

We publish no savings percentage. You test it in your own home for a full billing cycle instead.

60 days to decide

If you are not satisfied, return it within 60 days of delivery for a refund of the purchase price.

How it works

Four steps, one minute of setup

  1. 1. Plug it in

    One unit per 800–1,200 sq ft, plugged directly into a wall outlet — never a power strip.

  2. 2. Capacitors engage

    Reactive energy is stored and released locally instead of travelling through your whole circuit.

  3. 3. Current in the wiring drops

    Lower current means lower resistive losses and cooler conductors on those circuits.

  4. 4. Track your own kWh

    Compare kilowatt-hours against the same month last year, and return the units if nothing changes.

The device itself

A sealed capacitor unit, not a gadget with an app

Inside the housing is a passive power-factor correction circuit. No firmware, no subscription, no wiring, nothing to configure. It draws a negligible amount of power and runs cool.

No savings percentage claimed

We never promise a number off your bill. You measure kWh in your own home for one billing cycle.

Common questions

Is StopWatt legit?
StopWatt is a real plug-in power-factor correction device, and this domain is the official store — orders are fulfilled and refunded by us, not by a reseller. We publish no savings percentage and no celebrity endorsement, and every order carries a 60-day money-back guarantee.
Does StopWatt really work?
It supplies part of the reactive current used by motor-driven appliances such as pumps, compressors and HVAC units, which lowers current in your wiring. Results depend on your home's appliances, so we ask you to compare a full billing cycle against last year's kWh and return the units if nothing changes.
What exactly does StopWatt do?
It is a plug-in power-factor correction device. Internal capacitors supply part of the reactive current used by motor-driven appliances, which reduces current in the nearby wiring.
Will it lower my electricity bill?
We do not promise a savings figure. US residential meters bill real power in kWh, so any bill impact comes from reduced in-home losses and varies by home. Test it for a billing cycle and return it within 60 days if you are not satisfied.
How many devices do I need?
Roughly one per 800–1,200 sq ft, with extra coverage near large motor loads and on each floor.
How long does worldwide shipping take?
Orders leave our warehouse in 1–2 business days. Delivery typically takes 3–7 business days in the USA and 7–15 business days internationally, with tracking emailed on dispatch.
Which countries do you ship to?
We ship worldwide, and shipping is free to every destination we serve. Any import duties or taxes charged by your country are the recipient's responsibility.
How do I return an order?
Email support within 60 days of delivery with your order number and we will send return instructions.
