(ET, Wednesday, March 11, 2026 — It was the most-watched episode in Shark Tank history when this entrepreneur from UTAH won every single Shark over)
VoltBoost featured on Shark Tank

Never before has one  Shark decided to invest $10 million dollars alone into ONE company on Shark Tank.

Seeing that this is quickly becoming "the greatest step forward in home electricity " Mark Cuban was quick to lock in the deal of his lifetime to back a retired power grid engineer.

An engineer who spent 22 years inside America's electricity system tapped into a lifetime of experience to help find a real solution against the rising costs on your monthly bill.


The secret discovery?


A tiny device that you plug into any wall outlet near your breaker box, and within 60 seconds it starts saving you money automatically.


It's going viral on social media right now with thousands of people making videos that it saved them $100, $200 and even $400 a month on electricity.


Here's how it works…

"I've spent millions fighting the corrupt health insurance industry with my company Cost Plus Drugs. Now here's someone doing the exact same thing against the corrupt electricity industry. This is the fight America needs, and I'm all in. That is why I decided to invest $10 million"

1. It's Cuts Your Electricity Bill in Half

VoltBoost Benefits

VoltBoost's power conditioning technology forces your smart meter to record only the electricity you actually use, automatically, every single cycle.

Run the AC all afternoon in July…

Do laundry without checking the meter…

Keep every light on at night…

And NEVER overpay for electricity again.

Thousands of families who plugged in VoltBoost saw their bills drop dramatically within the first few months.

Some by half.

Some by as much as 70%.

No electrician, no rewiring, no monthly fees.

Just honest meter readings while you go about your day.

2. It Forces Your Smart Meter to Finally Tell the Truth (So You Stop Paying for Electricity You Never Used)

TrueVision lens detail

Your smart meter doesn't count every watt you use.

It takes snapshots.

Then the software guesses the rest.

Every guess rounds up.

That's why your bill stays high no matter how many lights you turn off or how many new appliances you buy.

VoltBoost stops that overcounting completely.

It forces your meter to record only real usage.

So your bill stabilizes instead of growing every single month.

It's 100% legal, completely plug-and-play.

And families are running their AC, doing laundry, and living normally with one small device, no matter what their old bill used to be.

3. It Saves You $1,500 to $3,500 Every Single Year on Electricity

TrueVision savings

VoltBoost replaces the money you hand the electricity company every month for electricity you never even used.

The average family was paying $200, $300, even $400 a month before they plugged it in.

After VoltBoost, those same families saw their bills drop by half.

That's not a one-time discount.

That's money back in your pocket every single month, year after year.

No more spending hundreds of dollars a month just to keep the lights on.

No more choosing between a comfortable home and paying your bills.

No more dreading the mailbox every month because you know what's waiting inside.

4.  It Protects Your Appliances from Harmful Surges and Spikes

TrueVision for near and far vision

Your electricity isn't always steady.

Sometimes it surges.

Sometimes it spikes.

Those jolts hit your refrigerator, your TV, your washer, your AC, every single day.

You don't see them.

But your appliances feel them.

Over time, those hidden jolts wear out motors, burn out compressors, and shorten the life of everything plugged into your walls.

VoltBoost catches those surges before they reach your appliances.

It smooths the current into one steady, even flow.

Like driving on a smooth highway instead of a road full of potholes.

That means your appliances run cooler, last longer, and break down less often.

No more replacing a $1,200 refrigerator because the compressor burned out from dirty power.

No more calling the repairman because your AC unit shorted during a spike.

One device guards your entire home's electrical system, automatically, every second it's plugged in.

5. It Works in Any Home or Apartment (Whether You Own It or Rent It)

VoltBoost doesn't care what kind of home you live in, because it works with any wall outlet you already have.

Old wiring, new wiring, apartment, house, rental, mobile home.

If there's an outlet, it works.

You don't need to own the property, call an electrician, or rewire a single thing.

Just plug it into any wall outlet near your breaker box and it starts correcting your electrical signal in under 60 seconds.

Renters love it because there's nothing to install and nothing to remove when they move.

Seniors love it because there are no tools, no ladders, and no confusing setup.

One small device covers your entire home, no matter how many rooms or how old the wiring is.

"After my husband passed, money got tight, and the $412 electric bill nearly put me in tears. I bought VoltBoost instead of cutting back even more. That was over a year ago. My bill hasn't been over $120 since. I run the washer, the dryer, the AC, everything. And I haven't called the electricity company once."

Michael Rodriguez Has anyone tried these? I'm tired of paying $300 every month on electricity and feeling like I'm burning money just to keep the lights on.

David Thompson Game changer! Plugged mine in near the breaker box and my bill dropped from $340 to $127 the first cycle. Running the AC again without checking the meter! Worth every penny!

James Wilson I was skeptical about a plug-in device lowering my bill but decided to try because of the guarantee. After 2 weeks my wife asked what was different — normally I'm the one complaining about the bill every month! 🙌

Amanda Foster Yes! You just plug it into any wall outlet. No tools, no installation, no permission needed. I rent too and it took 30 seconds.
