The Best Power Source for Water Ionizers

You and your family deserve the purest and healthiest drinking water available… but you certainly won’t get it from the tap or out of a bottle. However, you WILL get to drink the best water possible by using a water ionizer.

To ensure that you are selecting an optimally functioning alkaline water machine, it is important to recognize the key factors that influence performance…such as the amount of power available for use during ionization and the machine’s power supply source used.

Below – we’ll take a brief look at what an ionizer does and then dive deeper into the best power source for water ionizers:

How Do Water Ionizers Work?

water ionizers

Water ionizers are appliances found in kitchens and offices around the world that can raise the pH of your drinking water and provide a ton of health benefits.

Water ionizers work to filter your tap water that is then converted into alkaline water by the process of electrolysis.

You can ensure your family’s health and safety by using one of the top water ionizers on the market to enjoy the health benefits of alkaline water at home.

Why Is Power Important?

Water is “ionized” when an adequate electrical flow is conveyed to the water to make the H2O particle split – which frames positive and negative particles.

The more electrical ebb and flow conveyed to the water, the more prominent the “part” control – or ionization potential.

This is the reason most water ionizers utilize no less than 150 watts of intensity for ionization.

While electrical conductivity can be upgraded by utilizing cathodes with finishing (work plates), the more prominent the accessible wattage amid ionization, the more noteworthy the ionization potential.

Given the fluctuating mineral substance of source water in the United States – water ionizers utilizing countless (work) plates with high wattage, along these lines, remain to offer the best ionization potential in most source water regions.

Note: It’s important for you to check the amperage levels on any water ionizer that you consider buying – which we’ll explain below.

What Is a Power Supply?

A power supply is an electrical device that supplies electricity to an electrical load.

The primary function of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load.

What Are the Types of Power Supply Sources?

When choosing the best possibly quality machine – power supply sources are a hotly debated topic for many consumers.

The three types of power sources used in water ionizers today are:

  • Transformers
  • SMPS
  • SMPS Plus


  • Known as conventional “line-frequency”
  • Used in the early days of water ionizer technology
  • Use a single line of current to deliver power to the electrodes in the electrolysis chamber (Effective, yet generally considered less efficient)
  • The delivered power varies with overages dispersed as heat
  • Electrical currents are wavering and inconsistent during use
  • The water ionizer is not always getting the optimal power required and is based on user selection



  • Known as “Switched Mode Power Supply”
  • Introduced in various electronics over the last 10-15 years – such as computers, televisions, and other high-end gadgets
  • Used by many water ionizers today – especially machines that offer a higher wattage of power and more electrodes
  • Use two rapidly switching currents
  • Maintains the optimal electrical output based on the devices’ settings
  • Significantly minimizes fluctuations in the electrical current
  • Won’t overheat (stays cool)
  • Better electrical output
  • Smaller and lighter power supply system that affords more room inside the water ionizer machine or for reducing the machine’s size and weight


SMPS Plus:

The SMPS Plus includes everything that the regular SMPS has plus more…

  • Known as “Advanced Switched Mode Power Supply”
  • The seventh generation SMPS…referred to as the “Lucky 7”
  • Offers temperature control, optimal electrical output, and full adjustability
  • Superior power handling
  • Automatic shut off to prevent flooding
  • Functions much better than auto adjustable units
  • Voice-guided LCD touch screen support
  • More consistent levels of pH and ORP
  • Has changed the industry forever!

How effectively ANY ionizer performs comes down to the amount of power available for use during ionization, and the type of power system the ionizer uses.

What Is the Best Power Source for Water Ionizers?

The type of power system the water ionizer uses impacts:

  • The energy efficiency of the machine
  • How much heat is generated during ionization
  • Performance consistency

At maximum performance levels –water ionizers can be found ranging from 70 to 400 watts of power. The higher the wattage, the greater the chance that excess heat will be generated.

We have found that most water ionizers use SMPS power supply systems that use over 200 watts of power. Machines that use SMPS have longer warranty periods – likely due to the decreased risk of premature wear and tear on components from any excess heat generated.

However – the SMPS power systems are not as advanced as the SMPS Plus systems that are built with the newest and most advanced technology available on the market today.

So, if you guessed that the best power source for water ionizers is the SMPS Plus…you guessed correctly!

You’ll want to keep in mind that the SMPS Plus is only available in some top-quality water ionizers – so please do your research to avoid any potential problems that could result from choosing the wrong power source.

Amperage is important because when the SMPS Plus systems have the correct amperage levels – the systems can work at optimum performance.

Follow this amperage guide closely so that you can learn what the correct amounts of amps are needed for SMPS Plus systems, depending on the number of plates the machine has:

Plates Amps
5, 7, and 9 plate water ionizers 8 amps
11 and 13 plate water ionizers 10 amps

By following this guide to ensure that your SMPS Plus system has the correct amperage level – you will be able to enjoy using a top performing alkaline water machine to provide you and your family with the healthiest drinking water for many years!

Don’t accept anything less!
