KiloSave uses passive electromagnetic circuitry to smooth out voltage fluctuations in your home's electrical waveform. Stable voltage means appliances draw cleaner, more efficient power — they run a bit less hard for the same work. Over a full billing cycle, many households report up to 45% lower bills. Results vary based on your home wiring, appliance load, and usage patterns.

For best results, yes. A KiloSave helps the room it's plugged into — so one in the kitchen doesn't do anything for your laundry room or your AC.

Most homes have four to six rooms worth covering. The 4 Pack puts one in each main room, which is why it's the one most people choose.

Orders ship within 1–2 business days from our US warehouse. Estimated delivery is 3–5 business days.

The 4 Pack ships free.

Try KiloSave for 30 days. If it is not for you, email support@omnx.store within 30 days and we will arrange your return and refund.

$215 down to $142 in one month
Linda Berkmann
02/22/20264 Pack

Bill went from $215 to $142 in one month. Wasn't expecting that. The voltage thing is real — even my old microwave runs quieter. Plugging the 4-pack in across the house.

Modest, but real — and it added up
Kelsey Daniels
02/18/20261 Pack

Skeptical at first. Bought the 1-pack to test. The savings were modest but real — like $25-30 off the cycle. Just ordered the 4-pack to put one in every major room.

Response from Omnx
Thanks for the straight review, Kelsey. Savings depend a lot on home wiring and appliance mix, so a modest first cycle is a completely normal result — and one in each main room is where most households see the bigger difference.

The renter-friendly fix
Brittany Hollis
02/14/20262 Pack

I'm a renter. Couldn't justify calling an electrician. This was the renter-friendly fix I needed. Bill dropped, my old laptop charger stopped sparking, win-win.

He called it voodoo until the bill came
Renee Pearson
02/10/20262 Pack

My husband called this 'voodoo' until he saw the bill. Now he wants two more for his garage workshop. The wave-smoothing diagram on the box turns out to be real.

On a fixed income, $40 is groceries

I'm 71 and on a fixed income. Every dollar matters. The KiloSave saved me about $40 last month. That's groceries. Buying two more for my daughter's house.

Wife rolled her eyes. Then the bill came in at $98 instead of the usual $160. She wants to buy more. Buying 4 more this week.

My work-from-home bill finally stopped climbing
Jennifer Karras
01/27/20262 Pack

WFH for 3 years. My electric bill has been climbing every month. Plugged a KiloSave in near my desk + AC unit. Most recent bill is back to my pre-WFH average. I'll take it.

One in each room is what did it
Tom Vasilenko
01/22/20264 Pack

Bought the 4-pack. One in each main room. My summer AC bills have been brutal — last bill was the first time in 2 years that the AC bill didn't make me wince. Worth every penny.

Questions? We've Got You Covered

Common FAQ's

Honestly: it depends. Many households report up to 45% lower bills on the next billing cycle, but results vary based on your home wiring, your appliance mix, and how much electricity you use. Some users see modest savings ($20-40/month); others see larger drops. The 30-day money-back guarantee is there so you can test on your own bill, risk-free.

Think of it as one KiloSave per room. Each one works on the outlets around it, so it helps whatever is plugged in nearby — the fridge in the kitchen, the washer and dryer in the laundry room, the AC and TV in the living room.

Most homes have four to six rooms worth covering, and one KiloSave helps one of them. That's why most people go with the 4 Pack and put one in each main room.

Yes. Fire-resistant ABS housing, no fan, no motor, no moving parts. It draws negligible power itself and runs cool. Designed to live in an outlet permanently.

Standard US 2-prong plug, designed for 110-120V outlets. Works in every standard residential US outlet. Not designed for 240V circuits (large appliances like electric dryers / EV chargers).

30-day money-back guarantee. Email support@omnx.store within 30 days and we will arrange your return and refund.

Yes. Passive electromagnetic stabilization smooths voltage spikes that would otherwise reach your plugged-in devices. Fewer spikes = less stress on compressors, fridges, TVs, and electronics. This is the part of the product that's most defensible — even on cycles where your bill doesn't drop much, the appliance protection is still happening.

Orders ship within 1–2 business days from our US warehouse and typically arrive within 3–5 business days.

Built with fire-resistant ABS housing and UL-compatible electrical components. Tested for standard residential use. Safe to leave plugged in 24/7.
