Idea: Magsafe tile for bathroom

By "Magsafe" you're referring to the local inductive chargers marketed by Apple?

The only "issue" I see potentially is the range which is quite limited by EMI design requirements. I only have some simple ones for an early model Apple watch and the magnet isn't exactly strong.

As an idea, it has the advantage of being very low voltage and low current so that makes it safe (no pun intended) for use in a wet area where mains voltage use is either heavily restricted or severely limited. Haven't kept up with EU standards but even lighting in wet areas is being limited to 12/24 volts from the older 120/240v standard that older lighting systems used to require.

It should work ok on a horizontal surface but I don't know how we'd go about making one from the ground up with it being a closed standard. Qi2 is an open standard (1/2 the power delivery but compatible) so a Qi system might work, albeit at lower power delivery.

Correction: Qi2 (2025) now provides 15W and is expected to reach 50W in short order.

If I had something like this that was waterproof, I'd charge my phone while controlling music from the shower

I haven't looked into the devices proper but (save for the power input) they look fairly resistant to water and dust ingress. The only ones I have are all USB-C which is likely to be water resistant to at least IP

The IP (ingress protection) rating is a clue. With IP63 or greater giving protection for a device used in the shower.

The first number is for dust and dirt, the second number rates the water protection. 0 or 1 is little or no protection, 6 is fully protected from dust.

The second number goes all the way to 9 (with some devices rated to 9K). IP65 is about as high as most commonly available devices go, including modern mobile phones

For a complete breakdown Wikpedia has a handy table of the current standards here: https://en.wikipedia.org/wiki/IP_code
