Wireless Phone Charging Explained
Charging phones wirelessly is becoming increasingly popular. It will expand to the workplace, public spaces like cafés and restaurants, train stations and airports, as well as the home. In this blog, we will talk about what exactly wireless charging is and how to choose the best wireless charger for yourself.
Using a wireless charger isn't a brand-new concept. Wireless charging pads, mats, and other go-to products have recently grown in popularity and proliferation, putting this technology in the spotlight and spurring a ton of interest and demand. The global wireless charging market size was valued at $6.51 billion in 2018 and is expected to reach $40.24 billion by 2027, growing at a CAGR of 22.2% from 2020 to 2027 according to Wireless Charging Market report by Allied Market Research.
What's the challenge here, then? Many businesses and individuals are picking the wrong charger because of the wide variety of options available and the chargers' relative youth in the market. You need to know the ins and outs of this wide range of heyday wireless charging pads in order to select the best one for your brand or business.
The Workings of Wireless Charging
A century ago, Nikola Tesla was able to transport electricity across the air. Light bulbs at his New York City laboratory were powered by a mechanism known as resonant-inductive coupling that works by establishing a magnetic field between the transmitter and a receiver.
The Tesla coil, a tower with an electric-shooting coil at the top, was invented a few years later by Nikola Tesla. However, Tesla's ambitions of a wireless power system were far more ambitious than those of today. As with inductive charging, wireless charging for smartphones follows the same principles.
In a charging base, an electromagnetic coil, the induction coil, forms a magnetic field and acts as an antenna to transmit a field of energy. It is the phone's circuitry that turns the incoming electrical energy into usable electrical energy for the battery via a second, smaller coil.
Many designers have unified their wireless charging technologies under the Qi (pronounced "chee") standard so that their products work with a wide range of phone brands and models.
Wireless charging isn't only for smartphones; pacemakers and other medical devices can also be charged wirelessly.
Qi's Development over the Ages
According to the Chinese notion of Qi (pronounced "chee"), vital energy flows through everything.
When it comes to charging and transferring energy, the Qi standard specifies the number of different power levels. As part of the Qi standard, the device may request exactly how much juice it needs from the wireless charger.
An output of 5 W is supported by the Baseline Power Profile (BPP). Power outputs of up to 15 watts are allowed per the EPP standard. Mobile devices can be charged using either BPP or EPP; EPP is more advanced due to its fast-charging capabilities. Check out our blog for a more in-depth explanation.
Medium power is also supported by the Qi standard, which is planned to eventually enable up to 200 watts. Robotic vacuum cleaners, kitchen appliances and power tools are examples of larger equipment that employ this specification.
Qi-enabled Fast Charging
As a matter of fact, the difference between BPP and EPP has a substantial effect on your recharging experience. A lot of people assume that because EPP chargers can deliver more power, they'll be able to charge their mobile devices faster. This isn't the case. However, this isn't always the case.
The charging speed of your mobile device is constrained by the gadget's ability to receive power. No matter what sort of wireless charger you use, your smartphone needs to be able to receive 7 W of electricity in order to support fast wireless charging.
When it comes to quick wireless charging, it doesn't matter if your phone and charger have the feature. In order for fast charging to work, both the cable and the wall adapter must be capable of receiving adequate power. Using a 5 W wall charger and a 10 W charging pad, you'll only be able to receive the benefits of rapid charging if your device is connected to a 10W pad.
Fast wireless charging can only be achieved if you have adequate power in your cable, device, and charger.
The Wireless Phone Charging Advantages
As far as wireless charging is concerned, this is the most important feature. It eliminates the need for tangled connections and simplifies the process by allowing you to just drop your phone into the charging station.
There is no need to worry about where your cord is or how many chargers to buy. You'll be able to charge all of your devices at the same time using a wireless charger.
Chargers that are safer to use
The advantages of wireless charging will become clearer as more people utilize it. There should be a decrease in the number of counterfeit chargers on the market. That will ensure a higher degree of security for all users around the world.
Some wireless chargers may be used with practically any cell phone, regardless of the form or size of the charging port. This is a major advantage. The wireless charger can also be used to charge devices other than smartphones, such as tablets and e-readers.
Charging for many devices
We can now have multiple smartphones in the same room at the same time. Although most smartphones use the same wireless charger, Apple and Android devices may have somewhat different chargers. It is possible to charge many smartphones at the same time with a wireless charging station.
As well as helping you charge your smartphones, a multi-device charging station will also allow you to charge other devices such as tablets and laptops. There are less wires and international power adapters in your house or office if you use these.
Reverse charging, on the other hand, will allow you to charge other phones using the power in your own phone.
Best Wireless Charger Buying Guide
• There are now three performance levels: wireless chargers (5 watts), Qi fast chargers (7.5 watts for new Apple iPhones) and 10-15 watts for new Samsung models.
• Induction coils within (mature models) facilitate handling.
• Inductive chargers work with all Qi-enabled devices, but use the charger's specified USB power supply (5V/2A).
• Due to the newness of the product category, well-known brands and bestsellers frequently win.
• Manufacturers or brands offering appropriate devices include Samsung, Nokia, Anker, Belkin, Nanami, Ikea, Hama, and Zens.
• Induction chargers are frequently shipped without a power source. These are typically available – but you should check their power. The power source required is usually 5V/2A or 9V/1.67A, as stated in the dealer's product description.
Wireless Chargers: The Future of Charging Is Now
We anticipate that inductive charging will continue to gain popularity due to its many benefits. It will expand to the workplace, public spaces like cafés, restaurants, and airports, as well as the home. Everyone must determine for themselves whether a Qi charger and the associated wireless charging is helpful to them. We'll help you navigate the market and pick the best wireless charger.
