In a culture that is increasingly mobile, it is often inconvenient and even impractical to need to plug in a charger in order to boost the battery on a mobile phone. Using the phone hands-free while driving is accomplished with a car mount, but if the battery runs out, having the phone propped and ready to make calls or to get information is not very useful. Wireless chargers provide a solution, making it fast and easy to charge mobile devices on the run.
 

Device compatibility
The first consideration when choosing a wireless charger is device compatibility. Just like conventional chargers only work with specified mobile devices, wireless chargers have certain compatibility requirements. While brands, such as Nexus and iPhone, have their own wireless charging pads and docks, the compatibility of these devices is not limited to just mobile devices from those brands. Consumers should check the compatibility details of a specific wireless charger to ensure that they choose the one that is appropriate for their devices.

Technical specifications
Beyond the brand and model of mobile device, consumers must also consider the technical specifications of a wireless charger to ensure it effectively charges the device. There are two wireless charging standards that govern chargers. The Wireless Power Consortium (WPC) formed Qi and the Power Matters Alliance (PMA). The chargers of each standard only work with devices of the respective standard.
