SAMSUNG EB-U2500 - Battery charging tips and precautions - 3

  • You can charge the product using the charger (sold separately).
  • To save energy, unplug the charger when not in use. The charger does not have a power switch, so you must unplug the charger from the electric socket when not in use to avoid wasting power. The charger should remain close to the electric socket and easily accessible while charging.
  • When using a charger, it is recommended to use an approved charger that guarantees the charging performance.
  • Using a power source other than the charger, such as a computer, may result in a slower charging speed because of a lower electric current.
  • The product can be used while it is charging, but it may take longer to fully charge the battery.
  • While charging, the product may heat up. This is normal and should not affect the product's lifespan or performance. If the product gets hotter than usual, the charger may stop charging.
  • The actual capacity (Wh) is measured based on the battery's output current and voltage. It may differ from the capacity (Wh) indicated on the product, depending on the output power condition, the connected device's circuit configuration, and the operation environment.
  • If the product is not charging properly, take the product and the charger to a Samsung Service Centre or an authorised service centre.
