Who is Hiroshi Tanaka, the Japanese genius who developed a method to cut electricity costs?
Tired of forking out a small fortune on your electricity bill every month? Wish you could put that money to better use without compromising your lifestyle?
Look no further — a former Tesla engineer from Tokyo has come up with a solution to drastically cut power usage and save you a significant amount of cash!
We had the exclusive chance to interview Hiroshi Tanaka for EnergyNews after his shocking discovery about American electricity bills. In this article, we'll reveal how you can legally slash your electricity bills by up to 90%.
Hiroshi graduated with an engineering degree two years ahead of his peers and, in 2020, moved from Tokyo to Austin, Texas to launch a startup that would revolutionise the industry. There, he quickly teamed up with two other talented engineers — but their initial solar project proved financially unviable due to the cost of components.
But something else caught Hiroshi's attention: his first electricity bill in Austin was $430. Back in Osaka, his parents paid only around $35 for a similar-sized home. Something wasn't right.
This led the team to create a device that optimises electricity usage so effectively it can cut power bills for most households by up to 90%.
Three months later, it was an overwhelming success. Hiroshi tested the first PureVolt Pro™ in his Austin apartment — his bill dropped from $430 to just $71. Then he gave one to his neighbor Linda, whose bill plummeted from $405 to $69.
Word spread like wildfire. First in Austin, then in Houston, and finally in New York, everyone was talking about this incredible device that could slash their electricity bills without changing their daily routines.
What's this device that can slash your power bill by 90%?
Here's why the PureVolt Pro™ device works: It's a power factor corrector — the same technology that Japanese homes use to filter out "dirty electricity."
In a word (or two that rhyme), you just "plug and save." The best part? All you need is a free power point.
Once the device is plugged in, it immediately stops unnecessary energy from flowing through the electrical cables.
Household appliances create reactive power as a byproduct of their operation. In Japan, power companies are legally forbidden from charging for it. In United States of America, there's no such protection — so you're paying for electricity that does you no good.
PureVolt Pro™ corrects the power factor and eliminates reactive power charges from your bill. It doesn't affect your meter readings or manipulate anything. It simply filters out the electricity you shouldn't be paying for in the first place.
How does it work exactly?
Just like plugging in any other electrical device, you simply plug the PureVolt Pro™ device into an outlet, and it starts analysing and optimising your power usage (you'll only notice the difference when you see your bill).
Instructions:
- Find an unused power socket.
- Plug the PureVolt Pro™ device into the outlet.
- Leave the PureVolt Pro™ device plugged in 24/7 and enjoy up to 90% savings on your electricity bill without changing your usage habits.
If you want to move it, simply unplug the device and plug it into a different outlet. It's that easy.
P.S. A detailed user manual is included with the product.
How much could you save with PureVolt Pro™?
It's hard to estimate exactly how much you could save with PureVolt Pro™, as power usage and appliances vary from home to home.
However, to give you an idea, we installed the PureVolt Pro™ device in two different homes and compared the electricity bills from one month to the next.
First test: A two-bedroom flat (couple) of 55m²:
Before PureVolt Pro™, the average monthly bill was $180. After installing PureVolt Pro™, the next month's bill dropped to $32, a reduction of nearly 82%, without changing the use of appliances. That's over $1,200 in savings annually ($1,211.63), which is a significant amount.
Second test: A house for five people (two parents and three children) of 145m²:
Before PureVolt Pro™, the average monthly bill was $480. After installing PureVolt Pro™, the next month's bill dropped to $63.50, a reduction of 91%. That's over $3,500 in savings annually, which is a substantial amount for a family household.
One thing's for sure: the device saves money 100% of the time. In the worst case, you'll save around 80%, and in the best case, savings can exceed 90%.
One last thing to note: for spaces under 70m², just one PureVolt Pro™ unit is enough, but for larger rooms, you can use multiple units to maximise your savings.
Is it safe? Is it legal?
As mentioned, the device simply optimises the electrical current to prevent unnecessary energy consumption. It's not a device that manipulates the power meter. If it weren't legal, the company wouldn't be allowed to market it.
So, the device is 100% legal and risk-free. You're fully entitled to purchase it. If for any reason you want to stop using it, just unplug it.
As you might expect, electricity providers aren't thrilled about this product hitting the market and will do everything they can to keep you from hearing about it. However, they can't legally stop you from owning it or saving on your energy bills.
What's the price and delivery time?
The company has set the price of the PureVolt Pro™ unit at $29.99 USD. While this may seem expensive at first, it proves to be highly cost-effective in the long run, as it saves you money every month. For most households, the unit has already paid for itself within two months.

His costs have dropped by 85%
My dad recently lost his job, so he got this PureVolt Pro™ to cut costs. It worked so well that he told me I should get one too. His costs have dropped by 85%, which is incredible.

I feel liberated
I had no idea it was so easy to save money. I also didn't know that my energy provider was cheating me out of thousands of pounds. I feel liberated. I can't remember anything getting cheaper lately, and that's a lifesaver for me.
