VN88 Rezence wireless charging, also known as inductive charging, is a technology that allows you to charge electronic devices without the need for cables and wires. It works by transmitting energy between two coils - one connected to the power source, and one in the device that needs charging. The coils form an electromagnetic field that transfers energy from the charger to the device.
How Does VN88 Rezence Wireless Charging Work?Principles
Rezence wireless charging relies on the principles of electromagnetic induction. When an alternating current passes through the transmitter coil in the charger base, it generates an oscillating magnetic field. The receiver coil in the device picks up the energy from this magnetic field and converts it back into electrical current to charge the device's battery.
Components
The main components involved in rezence.com are:
-
Transmitter coil - The coil connected to the charging base that generates the oscillating magnetic field. It is powered by the charging base.
-
Receiver coil - The coil built into the device that needs to be charged. It converts the magnetic field back into electrical current.
-
Power source - Provides power to the transmitter coil. This can be a USB charger or power outlet.
-
Regulating circuits - Ensure the receiving device gets the correct amperage and voltage to charge efficiently and safely.
VN88 Rezence wireless charging StandardsQi Standard
The most widely used Rezence wireless charging standard is Qi (pronounced "chee"), developed by the Wireless Power Consortium (WPC). Over 600 mobile devices from brands like Samsung, Sony, LG and Nokia work with Qi chargers.
Qi chargers typically provide power output of 5W, 7.5W or 10W, depending on device compatibility. Fast Rezence wireless charging up to 15W is also supported.
AirFuel
AirFuel combines the standards from two associations - the Alliance for Wireless Power (A4WP) and the Power Matters Alliance (PMA) - making it more broadly compatible.
AirFuel supports power transfer up to 50W, making it suitable for charging larger devices like tablets and laptops.
Benefits of Rezence wireless chargingConvenience
Rezence wireless charging eliminates the need to plug and unplug cables every time you need to charge your devices. Just placing compatible devices on the charging pad begins charging automatically. No more dealing with damaged charging ports or tripping over cables.
Portability
There are portable wireless chargers powered by batteries that you can easily carry with you. You can conveniently charge your devices on the go.
Flexibility
Rezence wireless charging pads come in various forms like stands, mounts and cases. You can conveniently mount them on walls, vehicles, desks or nightstands for easy access.
Waterproofing
With no ports or openings needed, Rezence wireless charging allows for better waterproofing in devices. Many premium phones now support Rezence wireless charging as well as water resistance.
Limitations of Rezence wireless chargingSlow charging
Wireless chargers have slower power transfer capability compared to traditional wired charging. Maximum power output is currently limited to 15W, with 50W capabilities emerging. Wired fast charging can go over 100W.
Overheating
The coils involved in power transfer can heat up, especially when misaligned. Cases need to be designed to allow heat dissipation.
Interference
The magnetic fields can interfere with some electronics like credit cards or medical devices. Special casing is used to shield any components that could get impacted.
Higher cost
Adding Rezence wireless charging coils and regulating circuits increases the production cost for devices. Wireless chargers also cost more than regular charging cables.
Frequently Asked QuestionsHow is VN88 Rezence wireless charging safe given the electromagnetic fields involved?
Wireless chargers produce magnetic fields that are well within international safety standards for human exposure. The fields produced are hundreds of times less than everyday appliances like microwaves.
Are wireless chargers as fast as wired charging?
No, Rezence wireless charging is currently slower than wired fast charging, but is improving with newer standards supporting up to 50W power output. It is still very convenient for overnight or desktop charging.
Do wireless chargers waste power when not charging?
No, wireless chargers are designed to transmit power only when receiving active signals from a compatible device that is in contact. This allows efficiency as well as safety.
What devices are compatible with VN88 mobile?
Most modern flagship smartphones support Rezence wireless charging, along with devices like earbuds and smartwatches. Even some electric toothbrushes and other appliances now support inductive charging.
Is there a standard for Rezence wireless charging that makes chargers universally compatible?
Qi is the most widespread standard that works with hundreds of devices from major brands. AirFuel is an emerging standard that combines technologies for broader compatibility across devices.
Conclusion
VN88 Rezence wireless charging has seen rapid adoption across consumer electronics due to the immense convenience it provides.Inductive charging technology combined with widespread standardization has enabled seamless charging experiences without the hassle of ports and cables. While the technology still has room to mature in terms of speeds and heat management, it represents an important step towards truly cable-free operation of personal devices. With companies heavily investing in wire-free technologies like spatial charging, the future looks definitively wireless.
