Wireless charging is one of the best charging options as far as convenience is concerned. You don’t need to plug in your cable each time you need to charge your phone. Simply rest the smartphone on the wireless charger surface and the device will top up the power into the phone without any physical connection.
Wireless chargers work on the principal of induction and uses special coils in both the charger and the phone’s rear panel to induce the electricity and charge the phone. However, the efficiency is not as good as a regular plugged-in charger that comes bundled with the phone or a third party charger. There is a vast amount of energy drop as the electricity is converted from DC to AC-based electromagnetic fields and the phone again converts this electromagnetic induction into DC. Conversion of power or energy always sees a loss and hence the efficiency of the charging is reduced.
With most flagship smartphones having wireless charging options, the convenience of charging them wirelessly is highly appreciated — even if it is slowly charging as compared to the usual means. We shall definitely see wireless charging on almost all smartphones in the near feature and wireless chargers will be all around you soon. So whether you are in office, at home, in your car or at the bar, you will soon see wireless chargers all around you and all you need do is simply rest it on the surface and your battery woes will be taken care of. The convenience of wireless charging takes care of the multiple phone power sockets and chargers as they will all work across all brands, be it an Android or iPhone, or with a micro USB, Type-C or Lightning port.
With a plethora of wireless chargers available out there, you have to be sure you pick the right one with respect to quality and charging capabilities. While quality comes with a brand name, charging power or rating depends from version to version. Most phones that can charge wirelessly can charge from any wireless charger, but it all depends on the phone and the charger as to at what speed they can charge your phone. Given today, the highest wireless charging option is 15W and is seen in a few flagships as of now, while the rest are 10W and below.
We checked out the Digitek wireless charging pad DPWC-10W that came in to our office. While the tech is nothing new, it is definitely something that is soon evolving in terms of efficiency, speed and dropping price rates. The Digitek wireless charging pad DPWC is a 10W wireless charging power and has absolutely no user intervention required. Simply plug in a good fast charger to the micro USB port and you are ready to juice up your devices. Devices can be charged between 5W, 7.5W and 10W, depending on the phone and connected charger ratings respectively. We used them across all of our devices — Huawei, Google, Apple, Samsung, and they seamlessly power up with no hiccups or heating issues. However, the charging is definitely slower than a conventional physical connections
The charging pad has electromagnetic fields that help charge compatible devices on immediate contact. The company states that the 10W charger delivers a safer and more reliable wireless charging experience than standard wireless charging bases. The DPWC-10w features an inbuilt QI technology that helps offer ultra-rapid charging.
The Digitek DPWC-10W sports a slim design with an all-black exterior that is built completely of plastic. With four rubber pads at the base, it also ensures that the device does not slip around on the table. The rear features a micro USB port while the top face has a small dual colour LED that denotes the charging status. Simply place your smartphone on the pad and the LED will light up in blue denoting that the charging has begun. If the LED is red, it means that the phone is not placed correctly on the pad and needs to be moved to the right place to match the coils inside the phone.
A built-in smart IC Chip detects optimum charging current for respective gadgets and provides the needed power accordingly. The wireless charger also features short-circuit and heat protection to ensure maximum device and human safety with zero radiation, whatsoever. The pad needs a USB wall charger that is rated around DC 5V/2A or DC 9V/1.8A so that it can charge at maximum speed. The output voltage (wireless) is rated at DC 5V or 9V at 1.5A or 10 Watts max. Phones compatible are almost every model that sports wireless charging possibilities. These include phones from Apple, Google, Samsung, Microsoft, Huawei and BlackBerry.
The Digitek DPWC-10W is available for Rs 1,495 and if you use any of the latest flagship smartphones, we definitely recommend opting for a few of these and deploy each of these at home, office, car or any other place where you usually frequent. You may never have to carry your original charger or cable with you ever.
