You can tell a lot about a company from the first impressions they create. And VoltCore stood out as soon as we opened the package.

We were expecting not much more than the standard protective wrapping and maybe an order summary, but when we opened it, we were greeted with a thank-you note from the company.

This immediately set the tone for further product testing. From our experience, large tech companies rarely take the time to show appreciation to their customers, so this was a very nice touch.

VoltCore was created as a university project in 2019 by a couple of German engineering students. The idea quickly gained attention from investors and the business grew, yet their values remained as customer-oriented as the day they started.

With sustainability and saving money being at the forefront of everyone’s thoughts over the past few years, an effective and affordable energy-saving device rightfully became a favorite among many.

Everything pointed to a high-quality product, so let’s jump right into the review. 

Here’s what we found during our testing.

Our Test Results

Total setup time:  1-2 minutes.

The VoltCore energy saver came with detailed instructions, taking us through every setup step. That being said, they weren’t needed that much, as the device is incredibly intuitive to use

All you have to do is plug the device into your selected electrical outlet. That’s it!

This was one of the easiest setups for similar products we’ve tested out, so VoltCore is definitely a customer-oriented device. 

After we finished setting it up, it was time to see if this gadget really lived up to its hype. We ran some tests to see if the most essential features worked as it was promised.



Energy stabilizing –  stabilizing the electrical current in your home can help prevent serious damage and tragedies, so we knew this was one of the most important features to test. We used an ammeter to see how VoltCore affected the electrical circuit in our office and were impressed with how much the spikes were reduced.


Cutting idle energy usage – many of our devices are sucking up electricity even if we’re not actively using them – this is called “idle mode”. We tested this by leaving VoltCore plugged in for a week and compared electricity consumption in our office. To our shock, the electricity usage was cut by 46%!


Device protection – one thing we don’t often realize is that our electronics are more sensitive than we could imagine. Items that are smaller, such as light fixtures and desktop gadgets, can be severely damaged by power surges or unstable currents. This is a significant feature of the VoltCore, as it can help improve the longevity of your tech.


Electrical fire prevention – we measured and compared the current quality before and after plugging VoltCore in. Surprisingly, the current in our office was verging on dangerous instability levels. This is a great investment for those living in older buildings, as wiring may be unsafe. VoltCore is an excellent way to feel safe in your home again.

Similar tests were performed with all the selected energy savers, and VoltCore outperformed all of them

While these features might be enough to show you that VoltCore is worth your attention, we wanted to test it in other areas that can sway your decision while looking for an energy saver.


Most energy savers will cost you at least $175, usually more. The VoltCore energy saver normally sells for around $99.98, which is already an incredible bargain. They manage to keep the prices low as they sell exclusively online. This way, they don’t have to pay rent for physical store locations.

Right now, VoltCore is running a 50% off sale on their official website! So, you get the best energy saver on the market for only $49.99!

Ease of Use

While testing our selected energy savers, we noticed another clear advantage VoltCore had over other contenders – it was significantly easier to use. Other devices either had to take a certain amount of time to calibrate to the current of the home or had to be set up manually.

VoltCore had the easiest setup process by a long shot – all we had to do was plug it in, and it started working immediately. If you’re looking for efficiency,

Customer Support

If you weren’t convinced that VoltCore is exceptionally customer-oriented, this part of our review should tell you everything you need to know. 

You not only have the option to contact their support department via email, but they operate a 24/7 customer call center, allowing you to get clarification and assistance whenever you need it most.

Here are some customer reviews we’ve found on their website.

I bought VoltCore for my dad who was worried about using too much electricity in his house. Once it arrived, the directions were simple. He just plugged it in next to the breaker box and forgot about it. It does all the work for you! A month later, he suddenly remembered it was there when he noticed a huge difference on his statement which was way cheaper than ever before! Now he swears by VoltCore and is giving them out as gifts to all the family! Awesome little device!

I just plugged in last month and, boom – I lowered my electric bill right away! That was it, I was sold! I ordered several more for upstairs and my bill dropped even more the next month! Now I’m only paying half what I used to pay! I made sure to buy a bunch for my family and friends before the utility company catches on and you can’t buy them anymore! So worth it!

Eugene Miller – New Jersey

OMG this thing saved my life this summer. I was sent on unpaid leave and I literally had to pick between watching TV and eating because I couldn’t afford both! And the best thing is, It’s green! My friends really hate me when I nag them on how important it is to limit power consumption, especially in the summer time, and now I can give them an easy recommendation that they won’t hate me over! Thanks VoltCore!
