Will a wireless charger interfere with my wireless mouse?

Probably not. Qi charging uses 100-200 kHz, while wireless mice use 2.4 GHz—different frequencies. The real issue is poor shielding on cheap chargers or receivers, which can cause electrical noise and jittery cursor movement. For gaming, be cautious with budget gear; most Logitech or Razer handles it fine. For desk work, you’ll never notice. Test it: if the cursor stutters when near the charger, return the pad.
