TechTop Charging Process
Be the first to showcase TechTop in your designs. How convenient would it be to design spaces that now offer an additional value to the client without modifying the design?

Give your client the small solutions that matter. TechTop offers an innovative solution of freedom by embedding the wireless charging technology into your surface creation.




Please be sure to refer to the Fabrication Manual for complete instructions prior to starting the fabrication process.


I. Dimensions

II. Fabrication


  • Using the CNC machine, The maximum charging range of the transmitter is 9 mm with Viatera in-between the receiver and the transmitter. It is best recommended to set the range at 9 mm for the best performance and to not compromise the integrity of the stone.

  • Route on an area that does not interfere with substrate and is easily accessible. Refer back to the precautions mentioned in our Fabrication Manual depending on the type of the top layout.

  • Avoid routing where the charging unit comes in contact with water and stream for any case of implementation.


TechTop Fabrication Bracket


  1. Fit the charging unit into the bracket with coil facing up towards the bottom of the route-out.

  2. Apply approximately 1cm3 of silicon bond on three red-circled spots.Refer to Section 5
    [Bracket Dimension] in the Fabrication Manual

  3. Do not apply the glue in the center region of the coil.

  4. Place Viatera® upside down on a flat surface and attach the device set (charging unit in bracket) into the route-out.

  5. Wait until the bracket is thoroughly glued and fully attached to the bottom surface.

  6. After finishing regular fabrication of the surface/countertop, connect power adapter to the charging unit power jack embedded in the bracket and electrical outlet.

  7. Check to see if power is on and charging unit is working properly by simply placing the phone with standard Qi receiver. Find its correct charging spot located perpendicular to the center of the coil.

  8. It is recommended to place minimum 1/2″ x 1/2″ mark on the installed surface to indicate charging spot area on the center of charger coil.
