Phone Charger Greatly Improve The Use Of Mobile Phone Security
Now the Phone Charger is generally small, easy to carry, there have been a variety of general Phone Charger, in the selection of the Phone Charger when we have to check whether it is suitable for their own mobile phone use, current, applicable to the number of data lines are consistent and other issues.
Can the phone Phone Charger be universal?
1, mobile phone Phone Charger is not long-term common, each brand of original mobile phone battery, it is best to use the original Phone Charger, this can greatly improve the security of mobile phone use.
2, different mobile phone battery specifications are not the same, do not recommend using other models of the Phone Charger to charge, it is necessary to pay attention, do not take the chances, with other Phone Chargers to red, resulting in greatly shortened battery and life The
3, the phone in the charge, do not stay overnight, easily lead to fire and explosion, it is best to punch 2-3 hours on it.
4, mobile phone charging Now there are many general-purpose Phone Charger, such as travel Phone Charger, this can be used temporarily for emergency use.
Mobile phone Phone Charger maintenance:
1, when cleaning static. Regularly clean the Phone Charger and charging the interface. When cleaning, use a damp cloth, or an antistatic cloth. Do not use dry cloth!
2, waterproof and moisture. As an electronic product, inadvertent water or prolonged exposure to moisture in the air, will be on its internal electronic components caused by varying degrees of corrosion or oxidation.
3, anti-fall shock. Mobile phone Phone Charger is actually a fragile component, the internal components can not afford to beat. In particular, to prevent the use of the process accidentally landing. Do not throw, beat or shake the Phone Charger. Roughly treating the Phone Charger will destroy the internal circuit board.
4, anti-cold and heat. Do not place the Phone Charger in a place where the temperature is too high. High temperature will shorten the life of electronic devices, destroy the Phone Charger, so that some plastic parts deformation or melting. Do not store the Phone Charger in a cool place. When the Phone Charger works in a subcooled environment, when the internal temperature rises, the Phone Charger will form moisture and destroy the circuit board.
5, anti-strong chemical products. Do not use strong chemicals, cleaning agents or strong detergents to clean the Phone Charger. Clear the appearance of the Phone Charger can be stained with cotton a small amount of anhydrous alcohol scrub.
Phone Charger (Phone Charger) according to the design circuit operating frequency to points, can be divided into frequency machine and high frequency machine. Frequency machine is based on the traditional analog circuit principle to design, the machine internal power devices (such as transformers, inductors, capacitors, etc. ) Are large, generally in the load with a larger operation there is a small noise, but the model in the harsh power grid environment resistance to strong resistance, reliability and stability than the high frequency machine strong.
The high-frequency machine is a microprocessor (CPU chip) as a processing control center, is the complex hardware analog circuit burned in the microprocessor, the software program to control the way the UPS operation.Therefore, the volume greatly reduced, Weight is greatly reduced, the manufacturing cost is low, the price is relatively low. High frequency machine inverter frequency is generally above 20KHZ. But the high frequency machine in the poor power grid and environmental conditions, tolerance is poor, more suitable for the grid is stable and dust Less, temperature / humidity suitable environment.
All cell phone Phone Chargers are actually powered by a stable power supply
If the power supply, to provide a stable operating voltage and sufficient current) plus the necessary constant current, limiting voltage, time limit, overshoot and other control circuit components.
Original Phone Charger (finger charge) marked on the output parameters: such as output 4.4V / 1A, output 5.9V / 400mA, refers to the internal power supply parameters related to the regulator. Such as the output of 4.4V 4.5V can be used with the equipment, 5.9V can be used to 6V equipment.
