Invisible wireless charging, installed under the surface
The Stealth wireless charger mounts underneath your table, desk or countertop and charges phones right through the surface — wood, quartz, marble, glass — at distances of 20–50mm. No holes, no visible hardware, no cables on the table. A slim resonator pad on top marks the charging spot.
It is the charger chosen for offices, hotels, restaurants and furniture projects where design matters as much as power — including deployments at Haidilao restaurants and ByteDance offices.

Why choose a Stealth charger
Long-distance charging
Charges through 20–50mm of non-metallic material — real tabletops, not just phone-thick surfaces.
Works through stone and wood
Quartz, marble, granite, wood, MDF, laminate, glass and plastic all work. Metal surfaces do not.
Clean surfaces, clean design
No drilling through expensive countertops. The charger hides below; only a slim resonator pad marks the spot.
Safe by design
Foreign object detection stops power if metal enters the charging field. Over-current, over-voltage and thermal protection included.
Universal compatibility
Charges any Qi-enabled phone — 5W standard, up to 7.5W for iPhones and 10W for Samsung on compatible models.
Branding for projects
The resonator pad can carry your logo — a charging spot that also says your brand.
How installation works
- 01
Check your surface
Non-metallic material, 20–50mm thick at the charging spot (10–30mm for QB06). Use our checker or send us the specs.
- 02
Mount the charger below
Adhesive or screw mounting on the underside of the surface — a few minutes with basic tools.
- 03
Place the resonator pad
The thin pad on top marks the charging position and supports power transfer through thicker surfaces.
- 04
Charge
Put any Qi-enabled phone on the spot. That is the entire user experience.
Frequently asked questions
Will a Stealth charger work through my table?
+
If the surface is non-metallic and within the model's distance range — QB06: 10–30mm, QB21 Pro / QB31 Max: 20–50mm — yes. Wood, quartz, marble, granite, glass and plastic all work. Metal and metal-reinforced surfaces do not. For unusual materials we recommend testing a sample first.
How fast does it charge?
+
The Stealth series delivers 5W Qi standard, up to 7.5W for compatible iPhones and up to 10W for compatible Samsung phones. It is designed for convenient all-day charging at desks and tables, not for the fastest possible top-up.
Does it work with phone cases?
+
Yes, with most non-metallic cases up to about 5mm — the case thickness simply counts toward the total charging distance. Cases with metal plates, magnets or thick wallets may block charging.
What is the resonator pad for?
+
The pad on the surface marks where to place the phone and supports coupling through thicker materials. It is 1.2mm thin, waterproof and oil-resistant, and can be printed with your branding for commercial projects.
Can I order one unit to test?
+
Yes — and we recommend it for stone or unusual surfaces. Order a sample from our shop, test your exact installation, then scale to your project with bulk pricing.
