There are a few ways to check if your Apple magsafe charger you bought for your iPhone 12 13 14 is real or fake / counterfeit.
- Check R-NZ is written on the USB-C puck base
- Check if Apple recognized it by going to Settings > About > Magsafe Charger > Confirm A2140 shows up
- Check serial number is written on the cable
- Magsafe should snap hard and strong. Counterfeiters tend to cut on the magnet
- Bonus – Confirm the serial on the box, cable, and the serial mentioned by iPhone is the same
