On November 5th, 2016, both John and Gary Bedini passed away and EnergenX, Inc. came to an end at that point. John was the inventor of the chargers and solar charge controllers available through Tesla Chargers and Gary handled the business side of the company.

WARRANTY: The battery chargers/rejuvenators and solar charge controllers that Tesla Chargers offered came with a 1 year manufacturer’s warranty, but this warranty ended with the closure of EnergenX.

If you have a warranty issue that may be related to the fan, fuses/breakers, switches, LEDs or other items that are NOT related to the primary circuit module, which is encased in a white potting compound, we may be able to supply you with those items. To find out if we may be able to help you, even though the warranty has ended with the closure of EnergenX, please send us details to the email in the banner at the top of the page and we will do our best to assist you.

NEW PRODUCTS AVAILABLE: We are doing what we can to ensure that John Bedini’s technologies remain available to the public. The first technology that is finally back into production is the Bedini RPX 3.1MHz Sideband Generator available at http://sidebandgenerator.com

There are a couple more products scheduled for development, manufacturing and then distribution back to the public, but we do NOT have a timeline of when this will happen. We are unable to respond to emails or phone calls asking when the chargers or solar charge controllers will be available again. If you are on the Tesla Chargers mailing list, you will be the first to hear about any updates regarding making these products available again.

If you are not on this notification list, scroll down to join it.

Until then, thank you for supporting John Bedini’s work and we will do our best to make sure that the legacy of his work will remain available for the benefit of the people.

WARNING: There is an unscrupulous individual that has been bootlegging John Bedini’s battery chargers for several years now. These are inferior attempts at replicating John’s good work and in fact are based on stolen technology before John kicked this person out of his company.

We at Tesla Chargers have received many emails over the years complaining to us that they are not getting any customer service and then they find out that we are not associated with that company.

If you were victimized by that, you can submit a complaint on this website that was sent to us recently and posted on our forum – Rick Friedrich

Welcome to TESLA CHARGERS, the home of the most efficient, effective and advanced battery chargers in the world.

I know this does not sound “too modest”, but I think you will agree if you take the time to explore our product line and test this equipment for yourself. Just read some of the ASTOUNDING RESULTS that other people like you are getting by reading our Testimonials page!

In our rapidly expanding digital world, portable devices are popping up everywhere. From cell phones, to MP3 players, to laptop computers, to power tools, to LED lighting, to electric cars, every one of these things runs on batteries. More than ever before, our carbon footprint and our over-all pollution footprint depends on how efficiently we can charge those batteries and how long we can keep them in service and out of the landfill.

This rapid proliferation of devices has also had an unexpected side-effect. In most cases, each and every battery in all of these devices is different, and needs a different battery charger to charge it up. By now, most of us have between 5 and 10 different battery chargers all over the house. Many of these batteries are also expensive to replace, and only seem to last a year or two. This unfortunate situation has a variety of hidden costs built into it, and begs for a simple solution.

Now, that SOLUTION has arrived. The Universal 1AU charger from TESLA CHARGERS will charge ALL of these different types of batteries AND keep them in service for many years to come. And that is just one example in our astonishing line-up of Products. From 1.5 Volt AAA batteries all the way up to the full-sized Electric Car, TESLA CHARGERS has a solution for your battery charging needs.

If you want to learn the electro-chemistry involved in exactly how our Tesla Chargers charge and rejuvenate batteries, the Battery Secrets lecture is highly recommended. You will understand exactly why our chargers are above and beyond every other commercially available battery charging technology in the world.

Our Inspiration

Nikola Tesla
Nikola Tesla

In 1888, Nikola Tesla ushered in the Electrical Age with the invention of the 60 cycle AC power grid. It was Tesla’s far-reaching genius that fore-shadowed today’s Digital Revolution. Our company name, TESLA CHARGERS, is a tribute to this brilliant problem solver of an earlier age. Nikola Tesla was the first to explore the benefits of Pulsed DC Currents, and their unique applications to lighting and power production.

Mr. John Bedini, the inventor of the Tesla Chargers has mastered many of Tesla’s methods and demonstrated this for decades. The first battery charger/rejuvenator offered by Tesla Chargers was using Tesla’s exact “Method of Conversion“, which is described in the very important paper, “On Light and Other High Frequency Phenomena” by Nikola Tesla.

What that means is that an electromagnetic coil (inductor) is charged up to make a magnetic field. The power is turned off and the magnetic field collapses very fast and this produces a very high voltage spike with almost no current. This spike can be used to directly charge a battery contrary to what the popular belief is. This allowed the batteries to be charged with negative energy but they were not fully compatible with conventional chargers anymore.

However, the next generation of chargers cultivated these spikes into a capacitor, an extension to Tesla’s Method of Conversion, which was then discharged into a battery so that the battery was charged with positive energy and this allowed them to still be charged with conventional chargers if desired.

So you can see, Tesla Chargers isn’t just using Tesla’s name. We are one of the only companies in the world who actually do offer technologies that come from Nikola Tesla!

TESLA CHARGERS is proud to bring this technology into the 21st Century to provide the most advanced battery charging and rejuvenation solutions available today.
