Chargers with USB output

 

— in this case, it means the ability to charge mobile gadgets from the charger — for example, smartphones or tablets. Usually, for this, the charger is equipped with its own USB connector (for power only), to which the appropriate cable is connected. This feature will be useful if there is no “native” charger nearby (for example, if it is lost or broken). However, before use, it's ok to clarify whether the mobile device allows work with third-party “charges”, and if not, whether it is compatible with this charger model.
