Hardware 1A Wireless Charging for the NS

flabbaba · Jun 28, 2020

Hi all,

I made this project two days ago. It's not final but the concept seems to work fine. This is wireless charging circuit, integrated in the shell and it manages to give out 1.1A to the battery when placed on a 15W wireless charger. I would definently shield the cables you see going on the metal edge. It is very slim and it connected dirctly to the test-points above the USB-C on the mainboard. It is testet with the reverse input of 15.1V and it holds up fine. It will not interfere with docking or datatransfer. It will charge up the 4300mAh battery from 0-100% in around 5 hours. I get alot of USB-C repairs in these days, and the idea here is that kids would be less likely to mess up the USB-C if having wireless capability. So here it is.... Other wireless-charging systems out there has a lot less amperage than this.

OMFG this is awesome. I really like to see hardmods on the nswitch. And this one is very useful. Does it connect to the battery or does it use the connections to m92t chip so the system knows its charging?

Thanks! Yes, the system sees it is charging. It's connected to the input rail of the USB-C.
It also worth noting that best placement of the induction-coil was on the plastic back casing. Thus it is possible to place the coil centered on the Switch-logo on the back for simplifying "aiming" when placing it on the transmitting coil.

Yes as it would block the cooling system.But to me this is a non issue. This mod should be pinned or featured IMO

I need to clarify that the placement is inside the plastic back-plate of the shell. Its not blocking thecooling system, or gets squished. The circuit used is made of a pretty cheap receiver/coil thingy bought on eBay, but I got rid of the original coil because of low amperage, and used a pretty descent coil used for Samsung Galaxy S8 or S7. These are thinner and much more efficient - and they are very CHEAP. Remember that these allow REAL wireless fastcharge on a Samsung, but finding the circuitry that negotiates this is not easy and probably is proprietary of Samsung or whatever. Many brands claim to deliver 2A, but really its more like 0.6A in best conditions with a 15W charger.

Hello! Love it, can you please clarify which pins you used? I am interested in doing this to my switch lite after seeing this guide, but I have concerns about it conflicting with the usb port for data transfer and charging:
