Short answer: if wireless charger customers complain about heat, the importer should check coil alignment, charging distance, FOD protection, input adapter match, case compatibility and packaging instructions before blaming the end user.
The buyer fear moment: "The customer says the charger is unsafe because the phone is hot"
Wireless charging naturally produces more heat than direct cable charging, but customers judge by touch. If the phone feels too hot on the nightstand, the product becomes a return risk even when it still charges.
QC checks before bulk order
| Risk | Test | Buyer note |
|---|---|---|
| Heat complaint | Temperature rise test with phone and case | Test for 2-3 hours, not only 5 minutes |
| Misalignment | Coil position and magnet hold check | Important for 3-in-1 stands |
| Foreign object risk | FOD test | Protects brand trust |
| Slow charge | Input adapter and output compatibility | Print required adapter wattage |
| Retail confusion | Packaging instruction review | Explain case thickness and position |
