Frequently Asked Questions about Corian® Design Charging Surface

Below are some of the frequently asked questions we receive on a daily basis. If you have any further questions please send us a quick note. Click here.
How does wireless charging work?
Wireless power, also known as inductive coupling, uses narrow magnetic fields that are a natural part of how electrial current moves through wires. It starts by creating a circular magnetic field around the electrial wire where a hidden coil amplifies the magnetic field, and the receiving device also has a hidden coil that can receive the magnetic energy created, thereby transferring power wirelessly. It's very efficient and safe compared to regular wires in traditional power cables.
How can people participate in wireless charging if they don't own a special case or power connector?
Some smartphones already include built-in support for PMA or Powermat® compatible wireless charging and customers can check for the latest information. However, we are also offering a new design called a "Powermat® Ring" (a wireless charging adaptor) which comes in several different variations depending on the type of device you have. The Ring is plugged into your phone and then acts as a receiver of the magnetic energy created by the technology embedded in the tabletop.
Is wireless charging faster than wired charging?
Powermat® wireless charging will charge your phone at approximately the same rate as your traditional power cable does.
How do I update the charging surface firmware?

Can you charge other devices besides smartphones?
Yes, Powermat® technology is scalable and versatile. We can charge any range of devices depending upon the specific makeup of the wireless charging spots which are initially configured to support smartphones and other devices, such as tablets.
Can a laptop be charged?
No. A laptop requires higher energy to charge so it either may fail to charge at all or will charge at a much slower rate. However, Corian® Design Charging Surface has scalable technology and has the ability to upgrade to taptop compatibility when this technology becomes available.
What accessories are required to use wireless charging?
Until more smartphones come with wireless charging built in, you will want to buy a wireless charging case, a Ring or a PMA adaptor for your smartphone. Wireless charging accessories are available at online retailers, at AT&T stores and in major electronics stores. Customers can visit or to learn more.
How close does my device need to be to the charging spot to charge wirelessly?
The device must be directly on top of the charging spot. This ensures that the transmitter in the charging spot and the receiver in the device can transmit power.
Can I use my device while it's charging?
Yes, provided it is within range of the charging spot.
How many devices can be charged at once?
One device can be charged per charging spot.
Which devices now and in the future will have this technology embedded?
It's too soon for us to tell exactly which models will have wireless charging embedded, but we believe that it will eventually become a standard embedded capability just like Wi-Fi. AT&T and many other OEMs are part of the PMA and are expected to help promote the PMA standard into handsets. In fact, recently AT&T announced that they expect PMA technology to be built into their phones in the near future.
What are the environmental benefits of wireless charging?
The World Economic Forum designate wireless power as one of the most important environmental technologies for coming years. Wireless Power helps reduce the number of AC adapters, and ultimately can help us shift from AC to DC altogether (note that renewable energy like solar and wind is generated in DC, and portable devices consume DC, and the conversion to AC and then back to DC is very wasteful). In addition, wireless power adds intelligence to the system, ensuring power is used only when needed.
Is this wireless charging an industry standard like Wi-Fi?
Absolutely. The standard set by the PMA (, is backed by AT&T, Starbucks, P&G, Flextronics, Powermat, Energy Star and many others.
Is this compatible with the Qi version of wireless charging?
Yes, the Powermat® solution is based on the specification of the PMA and Qi.
What is the energy efficiency of wireless charging as compared to a plug-in cable?
Wireless Power itself is very efficient and is estimated to save more power over a 24-hour period compared to traditional cabled solutions.
Do the Charging Spots take information off my phone when I use wireless charging?
Not at all.
Should customers be concerned about the safety of wireless charging?
No. Wireless charging is safe and Powermat® is committed to supporting the highest safety and standards, such as including UL (product safety) and CE (conformance European).
Can you potentially be shocked by the Wireless Charging Spot?
No. Powermat® transfers energy, not electricity. The transfer of electricity is done by means of magnetic induction which you can learn more about at It is a sealed system and there is no chance of either electrical sparks or shocks. Wireless power is inherently safe.
Is it possible for wireless charging to damage a customer's device?
No. Powermat® is a 'smart' technology that delivers power only to the extend needed and then stops charging when the device has reached maximum battery capacity.
Can devices overheat or overcharge using wireless charging?
Will using wireless charging decrease the efficiency of my battery over time?
No. In fact, use of Powermat® wireless charging protects the integrity and efficiency of your battery because it identifies the precise amount of energy needed to charge the battery and delivers only that amount of energy before stopping.
