Wireless charging - very convenient and practical thing. However, not every manufacturer equips its gadgets device similar function. And it is quite easy and inexpensive. How to pump your smartphone will tell now.
In order to equip the favorite smartphone flagship wireless charging function, need not so much.
First, the base is the same charger. Most often it performed in the form of a small circular area with access to the charger. For the experiment, take unnamed model with a nice blue LED light. Powered by power supply 5 V, 2 A (conventional USB), is fed through a standard microUSB-port. At the output device gives a current with parameters 5, 1A, it is sufficient to charge most devices even in operation.
The second element is needed upgrading - antenna, by means of which charging takes place in the region of the smartphone. Typically, the distance is a minimum, by the way, but easy to use without wires for someone can be significant. For example, the base can be built in the dashboard of the car or put on the dresser next to the bed: come, put, lay down to sleep. And no search is performed.
The market is represented by the mass of a variety of universal antennas for smartphones. They are suitable also for other equipment, but here you need to think about the placement. Antenna (we - Chinese copy of the ring) Is a coil plate with hidden similarity in paper envelopes. Because it is carried out with plug microUSB, although if desired it can be any other soldering. It is worth noting: the coil operates in only one position with respect to the charger. As the cable for connection with a smartphone flat sachets may require opening and overturn the coil for the antenna (as in our case). The coil should be directed towards the open side of the charger.
After that, everything is very simple: we connect the plug to your phone, hide the antenna under the lid or cover and use.
Note: on the charging base give the necessary parameters of the power supply unit (if used with - 5 V, 2 A). They need to provide. At lower power charging current will be very slow. Perhaps for adequate operation required to replace the power cord that came with the charger, because not every USB-cable can be passed through a full-fledged 2 A. As you can see, tester It indicates adequate parameters only when connected directly Orico line filter using high-quality cable.
