1. A method for charging a barcode reader in a charging cradle, the method comprising:
detecting that the barcode reader is coupled to a first interface of the charging cradle for the barcode reader, wherein the charging cradle is to charge the barcode reader over the first interface;
detecting that a spare battery of the barcode reader is coupled to a second interface of the charging cradle, wherein the charging cradle is to charge the spare battery over the second interface;
receiving, via a connection between the charging cradle and a port of a host power source, an indication of a magnitude of an input current that the host power source is capable of delivering to the charging cradle over the connection;
comparing the magnitude of the input current to a threshold magnitude;
responsive to the comparing, determining a charging order in which to charge the barcode reader and the spare battery using the input current from the host power source; and
charging the barcode reader and the spare battery in accordance with the charging order.
