2, how about hand charger? It's no use! The electricity generation is very small! It's not enough to support normal phone calls! And it's bad for the phone! The current is very unstable! Can damage the electrical panel if you really don't have enough power, mobile power is better. How convenient the charging bank is! Hand charger is widely used in various fields, especially in the field of life is widely used in domestic mobile phones, domestic cameras and other common electrical appliances.
3, the domestic hand charger can charge the phone in the case of no power supply, has the function of emergency charging, and has a wide range of application prospects.
4, the hand charger is suitable for camping in the wild or for a long time without power supply environment, low efficiency, poor stability, inconvenient use. The solar charger is only suitable for use in the case of strong sunlight, fluorescent lamps or cloudy days almost do not work, and the drawbacks of environmental impact make it not suitable for daily use.
5,. No power is needed, just turn the handle hard and it can be used as an emergency charger for domestic mobile phones. 2. Built-in common LVoltage.
The working principle of the hand charger is to use the kinetic energy generated by manual shaking to convert into electrical energy through the internal micro precision motor. This process involves a manually optimized program that generates negative pulses with a variable time depth of 12-8 milliseconds to maintain the optimal electricity-to-chemical energy state of the plate inside the battery. This charger has applications in many fields, especially in life, where it is widely used to charge common appliances such as mobile phones and cameras.
Domestic hand charger usually refers to a kind of use of the kinetic energy generated when shaking, so that its internal micro precision motor high-speed operation to generate electricity, according toThe 12-8 millisecond variable time depth negative pulse generated by the manual optimization program keeps the battery inner plate in the best state of power to chemical energy charger. Hand charger is widely used in various fields, especially in the field of life is widely used in domestic mobile phones, domestic cameras and other common electrical appliances.
Hand charger can charge the mobile phone in the case of no power supply, has the function of emergency charging, and has a wide range of application prospects. Motor production method: The copper wire (enamelled wire) is wound along the two end faces of the spool into a coil group. Secure the coil winding with a rubber band. Thread the skewer through the center of the spool to both ends of the coilConnect the point to the metal washer and place the washer over the skewer.
1, first of all, make sure that you have accurately inserted the connector of the attachment adapter into the charging port of the domestic (cottage) mobile phone. Next, insert the other end of the adapter cable into the dedicated socket of the hand charger to ensure that the connection is secure. Then, start shaking the handle. At a speed of 5 revolutions per second, keep rotating in a clockwise direction so that the phone can start charging.
2. When charging the phoneA. Insert the connector of the attached transfer cable into the charging interface of the domestic mobile phone. B. Insert the plug on the other side of the conversion cable into the socket of this product. C. Pull up the handle and rotate clockwise at a speed of 5 turns for 1 second to charge. 2. As an emergency light, turn the handle and turn clockwise at a speed of 5 turns per second, and the LED light will be lit.
3, the principle of mobile phone hand charger is: a small DC motor, through the gear to drive the motor rotor to do magnetic cutting, produce alternating current, through the rectifier voltage regulation to get a stable DC voltage.
hour. If you use the slowest 5W charger, that is, 5V1A, it takes 10 hours to be fully charged, and the fastest you can use the 18W charger to be fully charged in nearly 3 hours, mainly according to the maximum support charging power of your mobile power supply.
If you shake it all day long, it can be fully charged. This charger is usually used for emergency use, as long as it is enough power to temporarily use the phone. Domestic hand charger usually refers to a kind of use of the kinetic energy generated when shaking, so thatIts internal miniature precision motor high-speed operation to generate electricity, according to the manual optimization program generated 12-8 milliseconds variable time depth negative pulse to keep the battery plate in the best electric energy to chemical energy state of the charger.
Full of a 1000 mah estimate to shake a day. It can be considered for emergencies, but not for specialized work. If you often go out and have a lot of phone, you can consider a multi-purpose power supply, that is, a power supply with a polymer battery of about 1000 mah, and the price is not expensive, 20 to 25 yuan of 1000 mah, which can charge the mobile phone, but also for MP3/4/5 or other smallCharging of electronic products.
If you can insist on shaking for three hours can certainly be full, the charger power must not be less than 5W.
Said before is for emergency use, just charge to you can pass on the time on the line there is no need to full, if you must hand acid according to the output current 200MA charge 900mAH battery for about 4 hours. Of course, it is shaking while charging, less than 10 cheap (of course, this parameter is not guaranteed, and it is used as said on the second floor), the three-phase motor is done with tens of yuan, and the power is large and the life is long.
Based on manual optimizationThe 12-8 millisecond variable time depth negative pulse generated by the program keeps the battery inside the plate in the optimal state of power to chemical energy charger. Hand charger is widely used in various fields, especially in the field of life is widely used in domestic mobile phones, domestic cameras and other common electrical appliances. The domestic hand charger can charge the mobile phone in the case of no power supply, has the function of emergency charging, and has a wide range of application prospects.
