What Is Heunwa Power Saver Device?
Heunwa Power Save is a device that is advertised as an electricity saving box that can increase the efficiency in the circuits at your home, office, workshop, restaurant, …etc., and significantly lower the bill.
The truth is that this is the same device that is sold under many different names on Amazon and on independent sites, such as the one I exposed in my PowerVolt scam review.
How Does Heunwa Energy Saver Work?
The way it is explained by the seller, Heunwa power saver works by plugging it into a socket outlet close to electrical loads, and it will improve the energy usage at the circuit where it is installed, by storing the “dirty energy” that would be lost otherwise and you would be billed for anyway.
And this is supposed to lead to around 20%-30% reduction in your electric bill.
But are these claims true?
This is what I will answer now.
Does Heunwa Power Saver Really Work?
No, Heunwa Power Saver doesn’t reduce your electric bill based on the claims to sell this device and other similar devices.
These claims are misleading to those who no nothing about electric energy.
To explain it in a very simple way that anyone can understand, electric energy comes from the network in two components:
- One that you get billed for, called active energy, and Heunwa CAN’T reduce this one.
- One that you don’t get billed for because the meters don’t read it, called reactive energy, and this is what Heunwa and similar devices might reduce.
As you can see, Heunwa, if worked, could reduce the part of energy that you don’t get billed for and the meters don’t read in the first place.
The reason you don’t get billed for it is that it is a very small amount, and it requires special meters that cost the utility company more money than the normal meters, which makes it not feasible to install them.
Only for big factories, it becomes worth it for electricity companies to install such meters, and then factories would install devices that can do this job, called capacitors.
But for small consumers, power savers don’t work on lowering the bill, and this includes Heunwa and all other similar devices sold under different names.
You might ask now:
But What about The Heunwa Customer Reviews on Amazon?
Well, if you check the consumer reviews on Heunwa on Amazon, you will notice that the 5-star reviews represent a small percentage of all the reviews.
There are may buyers who complained that the Heunwa power save device didn’t lower the bill even after months of using it.
And even the positive ones, assuming the buyers were not incentivized to give high ratings, they would be based on the fact that the reviewer’s bills went lower because their use of different appliances went down, either because the lockdowns started to end, or because of the seasonal changes like it is when spring comes and you stop using a lot of hot water or space heaters and AC units.
Think of it.
You never had the same bill twice.
Sometimes it increases, and sometimes it decreases.
And mostly, these reviewers had lower bills on the same months they started using the Heunwa device, and the lower bill was caused by the change in their behavior, but they mistakenly thought that it was because of the Heunwa power saver.
There are no Heunwa consumer reports that can be verified to show that the device saved even 1% on electric bill.
Heunwa Device Price
Heunwa is sold for around $12.99, but it doesn’t seem to have a money back guarantee.
I don’t recommend getting it because you would be disappointed of the results.

What can you call a device that is promised to lower your energy bill by 30% but doesn’t actually do that?
