1.57"(40mm) NiiTTER Invisible Wireless Charger, Under Desk Wireless Charger, Under Counter Charging for iPhone 17/16/15/14/13/12/ Samsung Galaxy S25/S24/S23/S22/S21(Adapter Included)

Works well, but not super fast and you need to align it pretty perfectly

Won't stay stuck plastic or granite the included tape won't stay stuck had to use a different charger and or diffent sticky stuff.

This product did exactly what it was supposed to do. I installed it on the underside of a desk that was 1 inch thick – worked like a charm! Super easy to install. And the indicator it was included to ensure proper placement of the top pad, was amazing!

Took great care to install. Work once. Now my phones won’t charge. The sensor lights up. Phones are not charging. Please help

You need a sticker on the surface of the table onto which to place your phone. The phone heats up during charging and the surface of the sticket eventually, after a couple of months, will wrinkle up and deform. It looks a real mess. I should have just used a regular charger with an exposed cable.

I just got this, and played around with it a bit. The table I'm going to put it under hasn't been built yet, so I can't install it, so I just held it under a similar table. I put the alignment card/sticker over the charger, the lights light up, then I set the other sticker on that, put my phone on it, and it started charging. It couldn't be easier to get it working... Others have noted that you have to be pretty accurate with how you set your device on the sticker to get it to charge. All wireless chargers I've had (in my Tesla, Samsung, other expensive ones), it's the same... I can't speak for how reliable this will be or how long lasting, but I need at least 4 more of these. I will be buying this brand. I'm pretty impressed.... Also, for others that get this, the box wasn't sealed and the device wasn't in plastic. I was concerned it was used, but I think that's just how it's packed. All the parts were there, none of the stickers were missing or used. So, I'm pretty sure it's not used.UPDATE: I tried it on my 1 inch granite countertops. It worked just as well as 1 inch pine. And this was just holding it under the counter, by hand and just setting the stickers and phone on top. I’m very impressed.

Very easy to install unit and the addition of colored pad stickers is nice, however that sticker has gotten a large amount of bubbles in it due to heat from the unit when charging my phone.

Love the idea, have to get it exactly center or won’t charge. Left my work phone on it and after an hour it only charged 6%. Works once in a while
