Can i Use A USB Charger As a Power Supply? | ZONSAN
1. The device being charged voltage and USB voltage is the same, the general USB standard voltage of 5V, the current standard of 500mA.
2. The device being charged has a USB port on one end.
How to Use Mobile Charger As Power Supply?
On the premise of confirming that the above conditions are met, you only need to connect the mobile charger and the device to be charged with a usb cable, and then you can directly plug it into the socket for charging.
Charger VS Power Supply
What is the difference between charger and power supply? The usb charger and power supply are AC power through rectification and filtering voltage stabilization. Usb charger is only suitable for short-term charging, the output DC voltage requirements are not very high; power supply is the rectification of the output DC voltage, current for further refinement of the process, the final output of the supply DC voltage and current more stable, can be long-term power use.
Usb Charger: The usb charger is generally used to charge some electronic devices in the short term, rather than long-term unrestricted energized use. For example, to cell phones, tablets, electric car charging with the customary have become chargers. Because in the charging time to these electronic devices regardless of the length, in principle, as long as the full charge can be unplugged.
Since usb chargers are designed with a maximum value based on the amount of power required by the device using the electricity. For example, the output current of the charger for charging the jukebox has two kinds of 500 mA and 1000 mA, and there are also 1500 mA and 2 and 5 mA for charging smartphones.
Charger because only at the beginning of the charge output current will be very large, and as the charge continues, the phone, tablet or jukebox inside the lithium battery power gradually increased, the charging current becomes smaller and smaller. Finally, under the joint control of the phone and tablet and the charger itself (some chargers will automatically light up green), the charger will only output a slight trickle of current until the phone, tablet and jukebox and other electronic devices in the battery voltage reaches the highest.
Therefore, the charger will only be in the beginning of the charge will output a larger current, and then gradually reduce, as long as the design is reasonable, and electronic equipment voltage, generally will not be a major problem, but the quality of substandard chargers in the beginning of the charge is easy to heat damage.
Power supply: Power supply generally refers to the device that gives continuous power supply to some household appliances. For example, to the current LCD TV power supply, to provide power to the refrigerator voltage regulator, to the wireless wifi monitor Power supply, etc. These power supplies are continuously plugged into the AC power supply from beginning to end, commonly known as the Power supply or voltage regulator.
Power supply is generally the AC 110-220 volts rectifier step-down voltage regulator output stable DC power, it is similar to other cell phone charger, phonograph charger basic, but the Power supply on the output DC voltage and current processing better and smoother, it uses the electronic circuit more sophisticated, electronic components better voltage resistance.
Power supply general output DC voltage or current have a stable rated value (some LCD small TV adapter is 12 volts 2 amps), generally will not have too much float. And the voltage regulator used on the refrigerator is available to manually adjust the output voltage to adapt to the local AC voltage, so that the output voltage is stable at an accurate 110-220 volts.
Combined, the charger and Power supply circuits are basically the same, but the requirements for them are different because they work at different times. If you use the charger as a Power supply to use, you want the charger output DC current voltage is more stable, and the power to be a little better, so it is estimated that the problem is not too big.
