How to charge a smartphone or USB tester needed for each Bashny.Net

The smartphone is charging too long? The battery charge lasts for less time than before? The device refuses to charge from a non-native charger? In all these cases the USB tester.


Problem with battery charging and battery chargers — eternal companions of modern gadgetman. Bad is charging? Whether cord for charging does not pass sufficient current, if the charger is unable to create the current necessary force. And if you run out quickly? Whether insufficiently charged due to the charger, whether the battery is already defective.

Unfortunately, the eye to identify the cause of emerging problems. Not to mess with buying expensive equipment, enough to buy one of the many variants of Chinese USB tester.

Unit the size of a normal USB flash drive will help to identify the cause of problems. Depending on the model on his screen you may receive a lot of information. In the simple — current settings current. In more advanced models may be different functions: capacitance measurement, testing chargers, the analysis of the charge process. There are models that can disable some of the contacts of the USB port and see what happens.



In addition, a huge number of chargers and USB cords are not suitable for charging modern smartphones and tablets do not match the strength of the current. Necessary for many devices 1.5–2 amps only give some particularly good specimens or products from proven manufacturers (which is always counterfeited). Here the tester will come in handy.



To work with the device is quite simple. The Internet (and the home charge device) can find necessary for the proper charging of the gadget settings. Then lace one end connects to the charger, the second to the tester. And, of course, to the test device. Starts the battery charging process, during which the tester indicates the necessary parameters: voltage and amperage. Thus it is possible to determine if there is enough of these options for fast and correct charging of the device.

If you charge a fully discharged smart phone or other gadget and at the same time, it is possible to calculate the real battery capacity. (Some testers indicate from passing through them charge in the desired quantities.) This will allow to say exactly whether it is time to replace the battery. published
