How does Tseetech’s stealth wireless charger power Qi Enabled Phones through the surface of up to 50mm thickness.

In the previous article, we’ve shown the performance of Tseetech QB21 through-surface wireless charger. The iPhone 12 Pro Max is juiced from 0% to 40% in an hour and fully charged within 3 hours, through the surface of 50mm thickness. This charging performance is about identical to the 15W Apple Magsafe charger.

How do we do this?

One of the secrets of Tseetech is the proprietary resonator pad design. Below, we can see the resonator pad sitting on the table and right under the phone. The charging distance means the thickness of the table.

Here is how this system works. Tseetech QB21, Tx(1), transfers wireless power to the resonator pad on the table. Simultaneously, the resonator pad delivers wireless power to the phone. Also, an ingenious magnetic field shielding method is used at the resonator pad to avoid magnetic field leakage which would lead to phones overheating. As a result, the resonator pad acts as a standard Qi charger and elegantly charges the phone with high efficiency.

The most attractive point of this approach is that the resonator pad is very thin. Thanks to Tseetech’s innovation, it’s just 1mm thick. In the end, what people see on the table is just a location sticker that indicates the charging position. It makes stealth beauty becomes a reality.
