How to teach your Smartphone charged without wires

In one of the last collections of useful accessories for smartphones , we talked about the external battery with integrated battery charger Qi wireless standard. The temptation to buy such a device is always very high, but even in 2016 not everyone is equipped with the flagship of the induction charging. Fortunately, to solve this problem is not difficult, and most importantly - cheap. This is possible with the help of external antennas to charge that connect to your smartphone through the existing port and using induction panel to recharge the battery.
The simplest and most convenient solution for the iPhone 5 and newer are Qi external antennas which are connected via a Lightning connector, and then hide under the cover. Ultra thin and light, they practically do not give out its presence, but also protect the port from dust and dirt. Note that for the 5.5-inch iPhone 6 Plus and 6S Plus will need to purchase a model with increased loop length .

Installing such an antenna and further use of the intuitive.

Technical characteristics of most induction chargers Qi standard:

• DC current: 1 A;
• Working distance: 2-6 mm;
• charging current: 500-1000 mA
• transmit power: 5 W;
• frequency: 100-200 kHz;
• electricity conversion efficiency: ≥75%;
• Size: 70 x 42 x 1.0 mm.

A major shortcoming of the previous model is scanty equipment. For example, the charging station and a case you will have to re-buy their own. At the same time possible to get everything in one set and begin to use immediately after preparation. The most common kit for the iPhone 5 and 5S includes a cover with built-in inductive charging Qi, charging dock, USB-cable and user manual.

Many Android-devices are supplied with a removable back cover that allows you to place the receiving antenna within the smartphone and eliminates the need to buy additional cover. A striking example is the Qi-antenna for the Galaxy the Note II of the Samsung , which is located under the device cover and can immediately be used to replenish the battery. The antenna is available only in black color and gives a current of 500 - 1000 mA.

A similar solution can be purchased for the Samsung Galaxy Note 3 , the Galaxy the Note 4 , as well as the flagship smartphone the Galaxy the S3 , the Galaxy the S4 and The S5 the Galaxy .

Such antennas are available for almost any smart phone. Universal Qi-adapters are available for devices with USB-connector in the center of the lower end, but now on the market are the antenna for almost all phones.

The main task of the user is the right choice between USB Type-A and USB Type-B, which determines the ability to connect the antenna to the phone.

Install any adapter is quite simple: remove the back cover, if this is available the phone design, connect the adapter to USB-port and gently place the adapter inside the enclosure. If the rear cover is not removed, place the antenna under the cover of your smartphone.

Those who buy an antenna separately, will have to buy the charging dock. They come in different shapes and colors, but their working standards should be the same as the antenna used. The most common today in the market of wireless charging Qi device .

If, for some reason, none of the options you do not vyshepredstavlennyh approached, you can use the universal search and find the adapter and charger for you .

How to make friends with Android machine

Smart Car System Android Auto and Apple CarPlay still not widespread, although it was in 2016. The number of car manufacturers have promised to release several models with built-in on-board computers to operating systems from Google and Apple. However, it is not difficult to guess that because of the presence of such a system in the vehicle cost may rise significantly, and change your car due to the appearance of only one of the new "features" can afford not for everyone. Fortunately, today's market there are many embedded solutions based on Android, which perform all the same functions, and even a little more.
It's no secret that because of the jump in the exchange rate range of electronic devices have increased significantly in price, but even now it is possible to find a relatively cheap but highly productive onboard All Android-computers .

Like the vast majority of computers in this class, the screen size is 7 inches with a resolution of 800x480 pixels. Declared support for GPS, Wi-Fi, Bluetooth.

The disadvantages can be ranked lower resolution display, a small amount of internal memory for data storage (but there is a slot for microSD) and a lack of Russian language firmware localization. However, if we increase the budget for at least 2-3 thousand rubles, it is possible to find a much more attractive solution.

For example, Panlelo 2DIN offers a 7-inch screen with a resolution of 1024x600 pixels, quad-core RK3188 1.6 GHz, 1 GB of RAM and Android 4.4.4 KitKat. The rest of the functionality Panlelo 2DIN identical to the previous model.

carefully study the specifications of the models, especially the size of the body;
some sellers ask when buying a car model and even asked to send a photograph of the front panel of the car in order to more accurately determine the compatibility with the computer;
better to give preference to models which provide native support for multiple languages, including Russian;
choose on-board computers with a possible new version of the Android operating system. Today, the most common of these devices Android 4.4 KitKat.
