Abstract
An example method for charging a barcode reader that can be implemented by a charging cradle includes: detecting that the barcode reader is coupled to a first interface of the charging cradle for the barcode reader; detecting that a spare battery of the barcode reader is coupled to a second interface of the charging cradle; 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.
