Portable communications device

A mobile wireless communications device may include a device housing, and mobile wireless communications device circuitry carried by the device housing. The device may also include a removable electrical power supply module coupled to the mobile wireless communications device circuitry. The removable electrical power supply module may include a module housing, and within the module housing, a battery cell, a DC-to-DC converter coupled to the battery cell, and an output inductor coupled to the DC-to-DC converter. The removable electrical power supply module may also include, within the module housing, a spark suppression circuit coupled to the output inductor, and an output voltage clamp circuit coupled to the output inductor. The removable electrical power supply module may further include a pair of output terminals carried by the module housing and coupled to the output voltage clamp circuit.

Mobile wireless communications device including removable electrical power supply module and related methods

An intrinsically safe portable radio device () having a portable radio device housing (). A first radio section () is an intrinsically safe circuit is (ISC) disposed within the housing and arranged to perform at least one function to facilitate operation of the portable radio device. A second radio section () ISC is disposed within the housing and arranged to perform at least a second function to facilitate operation of the portable radio device. Each of the first and second ISCs independently satisfy a defined standard for intrinsically safe devices.
