Frequently Asked Questions

Everything You Need to Know About StopWatt

StopWatt is a plug-in device using Electricity Stabilizing Technology (E.S.T.) to regulate voltage, reduce dirty electricity and EMF, optimize power factor, and protect against surges — all simultaneously. Simply plug into any standard 110V outlet and it begins working immediately with zero installation.

Results vary based on your home's size, wiring age, energy usage, and local grid stability. StopWatt may offer meaningful savings — particularly in homes with poor power quality or voltage instability. It is backed by a 60-day Power Saving Guarantee: if you haven't saved enough in electricity to cover the purchase cost, you receive a full refund.

Yes. StopWatt is both UL approved and RoHS compliant, making it one of the safest power factor devices on the market. It operates passively, stays cool to the touch, and is completely safe to leave plugged in continuously.

1 unit is recommended for every 800–1,200 sq.ft. For one unit, install it centrally or near your breaker box. For multiple units, place them as far apart as possible — ideally on opposite ends of the home or on separate floors — for maximum coverage.

The average home takes 3–4 weeks for the electrical current to be fully stabilized and filtered. We recommend allowing up to 6–8 weeks before evaluating your electricity bill. Your 60-day guarantee provides ample time to see and measure real results.

StopWatt offers a 60-day satisfaction guarantee from the date of delivery. If unhappy for any reason, return the device in its original packaging for a complete refund. All refund requests must be submitted via email to support@stopwatts.com. A 1-year standard warranty is also included on all orders.

StopWatt is safe to use with solar systems; however, the current version has not been thoroughly tested on solar-powered electrical systems, so results may differ. The 60-day money-back guarantee covers you regardless.

No. StopWatt is currently only compatible with 110V North American electrical systems. A 220V version is in development. All orders ship from the USA with no additional customs or taxes for US customers.
