Mobile phone charger principle (output mode)
Yes, the original mobile phone charger is the transformer, but its output voltage is only about 3V
Yes, but you have to know that it is different from the DC power supply, mobile phone charger output current will not be great, there are some charger output voltage is not clear, because it is constant current charge!
From the principle is possible, as long as the regulator DC power supply is a constant voltage source, and the output voltage is stable, there will be no voltage instability, such as voltage rise (voltage drop ignored), with a DC power supply to the phone Charging is no problem. As long as the regulator power output is stable enough, you can. Mobile phone charger is generally 5V, transferred to 5V,
For lead-acid batteries, according to the single cell 2.3-2.5V voltage set the charging voltage, that is, 12V battery for the six single cell, the charging voltage is set to 13.8-15.0V, with constant pressure way to charge.
Mobile phone charger can be divided into travel charger, seat charger and maintenance-type charger, the general user contact is the first two. And the market is selling most of the travel charger, travel charger in the form of a variety of common, cheap and cheap duck-type mini-travel charger, the general desktop card board charger, with LCD display of high-end desktop charge Device.
