Description:
Uses Apple's MagSafe charger (Qi2, 25w) and a Noctua 60mm x 25mm fan (with a USB to 3pin adapter).
Top piece friction-fits Apple's MagSafe charger.
Bottom piece goes on the other side of the fan, creates a mesh so nothing can interfere with the fan blades, and has pins that friction fit into the top piece.
Okay, but why?
Excessive and/or prolonged heat is bad for batteries. While newer phones (eg, iPhone 17 Pro or Pixel 10 Pro) have a vapor chamber for cooling… Wireless chargers create a lot of heat and are not cooled. Therefore, the wireless charger can and will spread heat to the phone. Even phones with cooling solutions will have heat leaking to them via wireless charger.
Belkin has a product that has Qi2 with 25w charging, but it's a 3-in-1 charger meant for the desk, and costs $130~…
This solution costs $60 for the MagSafe charger, $16 for the Noctua fan, and $9~ for the adapter. $85 all in with some DIY. A savings of $55~
Does it really help charging?
Preliminary testing (ANECDOTAL) shows the wireless charger does not rise much beyond room temperature. Without active cooling, the MagSafe charger usually gets very hot to the touch. Also the friction fit works very well.
Also don't ask why I printed in Glow In The Dark Blue… It's the filament I had on hand :)
