Simply plugs into a wall outlet with no setup required.
Many devices of this type contain:
These components may provide minor power conditioning in some situations.
The price is relatively low compared with dedicated surge protectors or power conditioners.
The biggest issue is the claim that the device significantly reduces electricity consumption.
For typical homes:
consume energy based on actual power usage.
A small plug-in device generally cannot dramatically reduce the electricity these appliances require.
The listing does not provide:
Without such evidence, large energy-saving claims should be treated skeptically.
A claimed 28KW capacity is extremely high for a small plug-in device and likely refers to a theoretical load rating rather than actual energy-saving capability.
Many plug-in “electricity saver” products sold online have been examined by electricians and consumer advocates. In many cases they were found to contain only a few inexpensive electronic components that do not meaningfully reduce residential electricity bills.
Some buyers purchase these devices expecting:
Such expectations are generally unrealistic.

The StopWatt Plug-in Smart Device is easy to install and may provide some basic electrical filtering or surge suppression, but the advertised electricity-saving claims are not supported by the information provided in the listing. Products of this type rarely produce meaningful reductions in residential power consumption.
If your goal is genuine energy savings, investments in efficient appliances, lighting, insulation, and smart energy management will typically deliver far better results.
Recommendation: Proceed with caution. It may function as a basic power-conditioning accessory, but it should not be purchased with expectations of significantly lowering electricity bills.
