Wireless Charging Pad (EMF, Heat Generation, Foreign Object) — household safety profile
Low riskQi-standard wireless charging pads using electromagnetic induction (100-300 kHz) to transfer power.
What is this product?
Qi-standard wireless charging pads using electromagnetic induction (100-300 kHz) to transfer power. EMF at the pad surface is significant but drops to background within 10-20 cm. Generates more heat than wired charging (30-40% energy lost as heat). Foreign metal objects (coins, keys, paperclips) on pad heat dangerously — Foreign Object Detection (FOD) mandated in Qi v1.3. Nightstand placement puts pad near sleeping head — EMF concern is theoretical at Qi power levels.
