Verified buyerMy bill went down
Took longer to open the box than to set it up. Plugged it in by the fridge and forgot about it. Then the bill came in lower. That's all I wanted.

Sound familiar?
Nothing in your house changed. So why is the bill higher?
You open the June bill and just stare at it. Same house. Same kids. Same AC at 76. And the number is the highest it's ever been.
So you go looking for what you did wrong. Nothing was left running. Nobody touched the thermostat. You start to wonder if you're losing your mind.
You already did the free stuff. LED bulbs in every room. Lights off when nobody's in there. Chargers pulled at night. A few hot nights you just sweated through. The bill still went up.
That's not on you. A chunk of that bill pays for power your home wastes behind the wall, and nobody ever told you to look there.
You're paying for power you never use
Every day, appliances like fridges, air conditioners, TVs, chargers and standby devices create small power spikes and wasted electricity. You pay for all of it. Count what stays plugged in at your place. The TV and the box under it. The router. The microwave clock. The phone chargers. The game console.
Each one keeps drawing a little power day and night, even when it looks off. That draw lands on your bill every month. And every time the fridge or the AC kicks on, your wiring takes a small jolt. If the lights dip for a second when the AC starts, that's what you're seeing.
Then the rate keeps climbing on top of it. The average US home price for power hit 18.31 cents per kWh in July 2026, up from 17.45 a year earlier, according to the U.S. Energy Information Administration. You can't change the rate. You can stop paying it on power you never use.

You cut back everywhere. The bill went up anyway.
And every time you ask for help, you get the same tips back. Here's why none of them made the bill smaller.
Unplugging everything
It works until you get tired of it. And you can't unplug the fridge, the router or the cable box. Those run all day no matter what you do.
Switching to LED bulbs
Good move, and most homes made it years ago. Lights aren't where the big draw is anymore. The fridge, the AC and the always-on screens are.
Turning the AC down or sweating it out
You set it to 76 and the house still sits at 81. You can't shut it off when it's 100 outside, and you shouldn't have to.
Switching supplier or going solar
A new plan changes the rate, not the waste. Solar costs thousands up front, and if you rent, it isn't even your call.
Every one of those asks you to do more. KORVEX goes after the waste on your bill that you can't reach by hand, and asks nothing of you once it's in the wall.
Meet EvenFlow
One plug that goes after the waste on your bill
KORVEX runs on EvenFlow. It sits in your outlet and cuts the wasted electricity and small power spikes your appliances and standby devices create, all day, so less of your bill pays for nothing.
1
Cuts standby drain
The TV, the router and the chargers keep drawing power while they look off. EvenFlow is designed to cut that waste, so you stop paying for it.
2
Smooths the spikes
When the fridge, the AC or the washer cycles on, it jolts your wiring. EvenFlow is designed to smooth those spikes, so less power goes to waste.
3
Looks after your appliances
Small spikes, day after day, are hard on electronics. Smoother power helps protect the fridge, TV and AC, and keeps a repair bill off your plate.
4
Plug in once, done
Push it into the outlet and the green light comes on. It works on your bill 24/7. No app, no Wi-Fi, no settings to touch.
Your house has a slow leak and a bumpy road, and your bill pays for both. EvenFlow is a shut-off valve for the drip and a shock absorber for the bumps, in one plug.

Real homes, lower bills
From people who plugged it in and watched the bill
Verified buyerVerified buyerLower bill, steady lights
Every time our AC kicked on, the kitchen lights would dip. Since we put two of these in, that stopped, and our bill went down. Small, quiet, no app.
Marcus D. · Houston, TX
Verified buyerBought a second set for mom
I was skeptical. Figured it was a TikTok gimmick. But it was cheap and there's the 30-Day Money-Back Guarantee. My bill dropped, so I ordered a set for my mom's place.
Linda K. · Tampa, FL
Verified buyerPaying less, doing nothing
Plug it in and leave it. I'm paying less for power and I didn't change a single thing. Wish everything was this easy.
Greg H. · Las Vegas, NV
Verified buyerFinally something I could do
We rent, so solar and new windows are off the table. Plugged this in behind the TV without asking the landlord. Our bill is lower and I didn't spend a weekend on it.
Priya S. · San Antonio, TX
Verified buyerStarted with 2, now have 6
Got the two pack for the kitchen and living room. The bill came down, so I ordered more for the bedrooms and the garage fridge. They don't make a sound.
Dave M. · Tucson, AZ
Verified buyerI stopped dreading the email
Every time the bill email landed my stomach dropped. Now I actually open it. The number is lower, and the little green light is oddly reassuring.
Sarah W. · San Diego, CA
Verified buyerWasn't sure, glad I tried
My wife thought I'd been had. Honestly, so did I. Then the next bill came in lower than the same month last year. She's not laughing anymore.
James T. · Sacramento, CA
Verified buyerOpened the bill at the table
Summer bills here are brutal and I'd stopped opening them. This July I opened it at the kitchen table, and it was lower. Ordered the four pack for the whole house.

Try KORVEX risk-freeQuestions, answered
Will this actually lower my electric bill?
Yes. Your home wastes power every day through standby drain and small power spikes, and you pay for all of it. KORVEX cuts that waste so less of your bill goes to power you never use. And if you're not happy with your bill, our 30-Day Money-Back Guarantee gets you your money back.
How does KORVEX work?
It plugs into a wall outlet and runs EvenFlow. It's designed to cut the wasted electricity standby devices draw all day, and to smooth the small power spikes that fridges, AC units and other appliances create when they cycle on.
Where should I plug it in?
Any standard wall outlet. Most people pick one near the things that run all day, like the kitchen with the fridge, the TV corner or the room with the AC. That's where most of the waste on your bill comes from.
How many do I need?
One works for a single busy room. Two suits an apartment or small home. Four covers the kitchen, laundry, living room and bedroom. Six is for large homes with several high-use rooms. More rooms covered means more waste cut.
Is it safe around kids, pets and my appliances?
Yes. It's designed for safe use in everyday homes and plugs in like a phone charger. It works alongside your appliances and electronics, and you use them the same way you always have.
I rent. Can I use it?
Yes. There's nothing to install, wire or drill, so there's nothing to ask your landlord about. You pay the bill, so you get the savings. When you move, unplug it and take it with you.
Does it need an app or Wi-Fi?
No. No app, no Wi-Fi, no account and no settings. Plug it in and the green light tells you it's on.
How fast does it ship?
Every order ships from the US with fast tracked shipping, so you can follow it to your door. Bundles of 4 units or more ship free.
Your lower electric bill starts with one plug
Stop paying for power you never use. Plug it in, no app, no electrician, nothing to change. Then let your next bill show you. Covered by our 30-Day Money-Back Guarantee.
