Quick answer

No, they are different products from different sellers. We do not have visibility into Pro Power Save's manufacturing, testing or support practices.

What each product is described as

StopWatt is a plug-in power-factor correction unit for 90V–250V outlets that uses capacitors to smooth current drawn by inductive household loads like motors and compressors.

Pro Power Save is marketed, per its own sellers, as a similar category of plug-in energy device. We have not tested a Pro Power Save unit ourselves and do not repeat unverified savings claims made about it.

What neither product changes

Any plug-in power-factor device, StopWatt included, works by smoothing reactive current near the outlet. It does not alter how your electric meter records kilowatt-hours. Because most US homes are billed on real power (kWh), results vary by household and may be minimal in homes with mostly resistive loads (ovens, baseboard heat, incandescent lighting).

Due diligence checklist for either product

  • Confirm the price shown on the ad matches the price at final checkout.
  • Read the return policy before paying, not after a problem arises.
  • Avoid pages that only accept payment methods without buyer protection.
  • Treat any 'as seen on TV' or celebrity-endorsement claim as unverified unless confirmed by the celebrity's own channels.
