How Much Does It Cost To Make A Wireless Charger?

Cost is always a major factor while buying anything. So, have you ever thought about How Much Does It Cost To Make A Wireless Charger?  Electricity pioneer Nikola Tesla developed magnetic resonant coupling.

The capacity to transport electricity through the air by establishing a magnetic field between two circuits, a transmitter and a receiver in the late 19th century.  However, it was a technology with limited practical applications for about a century, except for a few electric toothbrush models.

There are roughly a half-dozen wireless charging technologies in use today, aiming to eliminate cords from smartphones and laptops to kitchen appliances and automobiles.  Wireless charging is gaining traction in the automotive, healthcare, and manufacturing industries because it promises enhanced mobility and advancements that allow tiny internet of things (IoT) devices to get power from a charger hundreds of feet away.

PCBs, components, plastics, and other materials, for example?  In mass-production, you can obtain them for under $14 per. Quantities of 1000 to 10,000 cost around $20.  A PCB costs around $120 for a prototype (Bay Area Circuits protoboard).  If you can’t hand-solder it, you’ll have to pay roughly $1000 to assemble it.

How does Wireless Charging work?

Three forms of wireless charging exist.  Inductive or non-radiative charging pads are available, as are charging bowls or through-surface charger types that use loosely-coupled or radiative electromagnetic resonant charging that can transmit a few centimeters of charge; and uncoupled radio frequency (RF) wireless charging that offers a trickle charging capacity at distances of several feet.

The principles of inductive and loosely-coupled resonant charging are the same: a time-varying magnetic field generates a current in a closed-end wire. This is how it works: A magnetic loop antenna (copper coil) is used to generate an oscillating magnetic field that can cause current to flow through one or more receiver antennas. 

When the right capacitance is supplied, so the loops resonate at the same frequency, receiver-induced current increases, known as resonant inductive charging or magnetic resonance, and it boosts efficiency by allowing power transmission across long distances between transmitters and receiver. The distance of power transfer is also affected by coil size.  The greater the distance a charge can travel, the larger the coil or, the more coils there are.

For example, the copper coils in smartphone wireless charging pads are only a few inches in diameter, drastically restricting the distance over which electricity may be properly sent.  When the coils are larger, more energy can be wirelessly delivered. 

WiTricity, a startup born out of MIT research a decade ago, has aided in developing this strategy.  It licenses loosely linked resonant technology for various applications, including autos, wind turbines, and robotics.

Marin Soljai, an MIT physics professor, demonstrated the ability to transfer electricity over a two-meter distance in 2007.  At the time, the power transfer was only 40% efficient at that distance, meaning 60% of the power was wasted in translation.  Later that year, Soljai founded WiTricity to commercialize the technology, and its power-transfer efficiency has skyrocketed since then.

In WiTricity’s car charging technology, large copper coils over 25 centimeters in diameter for the receivers enable efficient power transfer across distances up to 25 centimeters.  According to WiTricity CTO Morris Kesler, resonance allows for high power transmission levels (up to 11kW) and high efficiency (more than 92 percent end-to-end).  WiTricity adds capacitors to the conducting loop, increasing the amount of energy that can be gathered and used to charge a battery.

Last year, Daihen Corp., a robotics company located in Japan, began deploying a wireless power transfer system that is based on WiTricity’s technology for automated guided vehicles (AGVs).  AGVs equipped with Daihen’s D-Broad wireless charging system may easily draw up to a charging spot to charge and then continue working in the warehouse.  While charging at a distance has a lot of potential, charging pads have remained the public face of wireless charging up until now.

Issues With Wireless Charging

The main drawback of wireless chargers is that you can’t use your phone while they’re charging.  You’ll understand why after you grasp how wireless charging works. However, to be clear, electricity is transmitted from the wireless charger to your phone via a small magnetic field.

If you move your phone away from the charging pad, the field will be broken, and the charging will cease. This implies that your phone must always be near the charging pad.

Wireless charging has been available for a long time, but in the context of smartphones, it only became popular a few years ago.  As a result, when compared to wired chargers, wireless chargers are somewhat “unusual,” thus it’s no surprise they’re more expensive.

Wireless charging also has the disadvantage of charging slower than conventional charging.  In today’s fast-paced world, everyone understands that time is money, and wireless chargers may appear outdated if they cause you to lag.

Pros Of Wireless Charging

Save Money With Wireless Charging

Although wireless chargers are normally more expensive than cable ones, they do become more reasonable in some respects.

Consider this: a single Qi wireless charger can charge your family’s phones and possibly a few more devices, such as your AirPods and Apple Watch.  As a result, there’s no need to stock up on chargers and wires.

How much money can you save?  It depends on how many devices you have; however, if you do the arithmetic, you’ll see that it’s well worth it.

You’ll Have A Charged Phone

Normally, you don’t charge your phone until it’s completely dead.  When you need to charge your phone but don’t want to put it down, plug in a cable, connect the charger to a wall socket, and you’re good to go.

But, because a wireless charger lacks an output connector, does this mean you can’t use and charge your phone simultaneously?  NO is the answer.  There are moments when you must put down your phone and return to your work.  Rather than leaving it on your desk, place it on a wireless charging pad. 

Your phone is charging without you needing to do anything, but it is no longer just sitting idle.  It’ll be ready when you need it, and ideally, it’ll last long enough for you to do what you want with your phone before recharging.

Wireless Charging Is Safer

Wireless chargers are slower than cable charges, which is a bummer.  However, the adage goes, “one man’s loss is another man’s gain.”

Because wireless charging utilizes less current than typically wired charging, it is more steady and hence safer for the battery.  A wirelessly charged phone will be in better condition and likely have higher battery life over the same period.  Speed isn’t always a good thing when it comes to wired chargers.

That’s alright if the following discussion did not persuade you sufficiently.  The “issues” with wireless chargers will be overcome someday, and in any case, there are creative wireless chargers on the market right now that operate far better than you would imagine.


That’s everything about How Much Does It Cost To Make A Wireless Charger?  Now you can select your charger according to your budget.  Wireless charging solutions are more accessible, practical, and affordable.  Why settle for an ‘old type’ wireless charger when you can buy the state-of-the-art magnetic wirelessly MagEZ Slider now and enjoy an unrivaled charging experience?
