What is Portable Wireless Charger?

Portable wireless charger uses electromagnetic induction to power a growing variety of devices. The technology may not be brand new, but its arrival as an option for smartphones has brought on new-found prominence. As more and more products ship with the feature, more and more users will wonder how this tech works.

There is a growing range of accessories that allow for Portable wireless charger. The mousepad charger is a great example, and it offers a convenient multipurpose solution for keeping your phone and mouse perpetually topped off.

Benefits of Portable Wireless Charger

It's convenient
Cords can be messy and easy to misplace, as anyone who has ever fumbled in the tiny space between the nightstand and the wall to find an elusive charging cord can attest. Portable Wireless Chargers, which consist of a simple, sleek pad or stand, stay put and make it much easier to, say, place a laptop on top and continue your work.

It's versatile
Portable wireless charger means constantly toting a slew of different bespoke chargers around to ensure each device can connect to a power source. Portable Wireless Chargers are generally one-size-fits all, so you can charge multiple devices on the same charging pad. One caveat: A couple of popular devices, like the Apple watch, don't support the Qi standard, which can be frustrating. We'll take a closer look at that below.

Auto-off
Once the device is fully-charged, the Portable Wireless Charger shuts off, resulting in saved energy, a safer charge, and less need to worry about overheating your battery.

Less wear on cables
You can still use cables to charge your phone when you need to, but using them less frequently makes frayed cables a thing of the past.

How does Portable Wireless Charger work?

Plugging a device into a charger means that the device is relying on conductive charging to move electricity from the power source to the device. Wireless charging, also known as inductive charging, is a method of charging electronic devices without the need for a physical connection between the device and the charger. Instead, the charging happens via electromagnetic fields.

Portable Wireless Charger usually requires two components: a charging pad or mat and the device in need of a charger. To conduct electricity, both the electric device and the charging pad contains a coil of wire. The connection between the charging pad and the power source (usually a wall outlet) generates an electromagnetic field. This electromagnetic field induces an electrical current inside the device, and that current charges the battery.

In order to induce the current, the charging pad and the device must be close to each other. The strength of the electromagnetic field depends on the distance between coils. The closer the coils, the faster the charge. There is one big drawback to wireless charging: It's generally not as fast as wiring your device directly to the power source.

Types of Portable Wireless Charger

Electromagnetic Inductive Charging
Electromagnetic inductive charging is the most widely used form of wireless charging technology. It is commonly found in our smartphones, smartwatches, wireless earbuds, and the wireless chargers prevalent in the market today.

Resonant Inductive Charging
Taking a step beyond electromagnetic inductive charging, resonant inductive charging allows for a slightly longer distance between the charger and the device. It utilizes two coils tuned to resonate at the same frequency, enabling energy transfer over a few centimeters.

Radio Frequency (RF) Charging
RF charging uses radio waves to transmit energy from a charger to a device. The charger, connected to a power source, converts electrical energy into radio waves. These waves are then captured by the receiver device's antenna, converted back into electrical energy, and used to charge the battery.

Wireless Charging Methods
As we've learned, most wireless chargers we see today utilize the electromagnetic inductive charging. Based on this technology, four popular wireless charging methods have emerged, each offering a blend of convenience, functionality, and style. Let's have a closer look.

Wireless Charging Stands
Wireless charging stands offer a convenient and elegant solution for desktop charging. Designed to hold your device at an optimal viewing angle, they enable you to interact with your device-be it for video calls, watching content, or monitoring notifications-all while charging wirelessly. Ideal for office desks, kitchen counters, or nightstands, these stands ensure your device is charged, visible, and accessible.

Wireless Charging Pads
Wireless charging pads are perhaps the most ubiquitous form of wireless chargers, known for their simplicity and ease of use. These flat, circular or square devices offer a straightforward approach to wireless charging: place your device on the pad, and it begins charging. Charging pads are versatile, compatible with a wide range of devices from smartphones to wireless earbuds. Their compact size and minimalistic design fit seamlessly into your homes and offices, providing a designated spot for effortlessly powering up your devices.

Polymer Science Materials in Portable Wireless Charger

Conductive and Non Conductive Films
Film and film tapes enable devices to meet electromagnetic compatibility requirements. Polymer Science offers a number of films suitable for wireless charging. Films help protect sensitive components against elements and also provide shielding. We have developed monitoring and process automation to ensure uniform layers of thin films, providing consistent electrical and optical properties.

Conductive Fabric
Conductive fabrics control electromagnetic problems with the addition of extreme strength, corrosion resistance and good static dissipation. The less resistance, the higher the magnetic field can be generated which results in higher output charging. Offered without adhesive, conductive fabrics may be used as an air loop gasketing material. The reduced weight and lower compression force compared to other materials are beneficial for many applications.
Conductive fabric tapes contour to irregular surfaces and are durable around edges and angles. Conductive textiles conform easily within plastic housings, and, although thin, they are exceptionally strong and durable.

As wireless charging technology advances, materials that provide dual functions are important. Fabrics protect more sensitive components, resisting wear, absorbing shocks and conforming to abrasive edges. This allows wireless chargers to become more compact while remaining effective and durable.

Foam
Lightweight conductive foam serves a number of purposes beyond shielding & grounding. To protect delicate components, the foam fills gaps, absorbs shocks and easily conforms to housings. Wireless charging systems are not unlike traditional electric devices. There are a number of sensitive and delicate components that must be secure to transfer power. Foams are widely used in aerospace, telecommunications, mobile consumer electronics and conventional automotive. The components within a wireless charger can be protected with an exceptional lightweight conductive or nonconductive foam.

Foil Tapes
Polymer Science offers foil tapes as a thin, lightweight, durable and malleable material. Both materials contour around tight angles and conform to irregular surfaces. When the landing zone is limited to millimeters, foil is an effective material. When considering the present designs of wireless charging and the greater plans to design infrastructure to support wireless charging across cities and roadways, foil tapes are omnipresent.
