Charging an iPhone without a charger or USB can be a challenge. Here are some tips to help you charge your iPhone without a charger or USB:

  1. Use an AC adapter if you don’t have a USB port on your device.
  2. Use the wall outlet to charge your device instead of the computer’s power supply.
  3. Charge your device overnight if possible. This will help it to be fully charged when you need it the next day.
