What StopWatt claims to do
StopWatt is a compact plug-in device marketed to reduce energy consumption by redirecting energy loss and stabilizing the current reaching your appliances.
Save money
Targets wasted electricity so less of it shows up on your bill.
Stabilized voltage
Smoother current means appliances draw power more evenly.
Less overheating
Reduced heat build-up in the circuits it protects.
Inside your home's wiring
StopWatt sits between your meter and your appliances — and slows that meter to a crawl
StopWatt is an inline device that routes all your home's power through it. As it does so, it takes that unoptimized, chaotic flow and applies structure, while recapturing power that would otherwise bleed off and be lost.
By optimizing power flow through your home's wiring, StopWatt helps you reduce power consumption at the meter. You can't make the meter turn backward, but you can slow it down to a crawl with our help.
Heavy-duty load? Big savings.
With a heavy-duty load, StopWatt can reduce your energy consumption immediately. You can reduce your power consumption just by installing a single device. It doesn't get much easier than that.
How does StopWatt save you so much? It's right there in the name. Our device stops voltage bleed, unbalanced current, and surges that not only waste power but can damage delicate devices and appliances in your home.
