1, no, the charge is too weak, there is no meaning. Not to mention constantly shaking, tired and not idle. Can be hand-operated generator power generation, can be solar power generation, can be wind power generation, charging treasure charging, actual power generation charging. Backup hand generator, yes.
2, hello: -- ★ hand power generation, charging for mobile phones, is unrealistic. ★ The charging current of the mobile phone is controlled by the power management module of the mobile phone, and the charging time is longer.Because the phone's power management module hardware is fixed, the charging power is also controlled, [increasing the charging power is impossible to achieve].
3, some, will reduce the life of the battery, because the hand generated electricity can not achieve a stable voltage and charging time is very short, so the charging voltage and current will be large, which will cause irreversible damage to the battery.
4, obviously false. If the mobile phone wants to get the function of hand charging, it must have the necessary hardware support. Software alone cannot do this function.
5, hand charger can be in the situation of no power supply'> Schematic diagram of hand charger, production of motor
1, 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.
2, the motor production method: the copper wire (enamelled wire) along the two end faces of the spool intoCoil group. Secure the coil winding with a rubber band. Pass the skewer through the center of the spool and connect the two ends of the coil to the metal washer, and put the washer on the skewer. The clay is divided into four pieces, and the spools worn by the bamboo skewers are mounted on two pieces of plasticine, and the other two pieces of plasticine are placed on either side of the coil winding to fix the magnet.
3, the principle is to use the hand generator after the rectification of the electricity (some issued is the direct current there is no rectifier circuit) to charge the battery, if there is a physical drawing of this schematic is very simple. The handle drives the rotor, and the magnet cuts the coil to generate an induced voltage. And atThe closed circuit forms an induced current, and forms a suitable charging current for the battery after processing. Due to limited energy, it is generally only suitable for using energy-saving LED to do the load.
4, the basic principle of hand flashlight Hand flashlight is a kind of equipment using high-power three-phase alternator for hand power generation, using this principle to generate electricity can be through the switching power supply to the flashlight circuit system for built-in charging. This flashlight can be used in a more emergency situation not only has a more convenient role to carry but also has a simple structure.
1, support PD fast charging, which means that the charging speed of the mobile phone is also very fast. Similarly, charging an Apple iPhoneX with Secretary Treasure can be fully charged to 50% in 30 minutes, faster than Apple's own charging speed.
2, first of all, pay attention to when charging the mobile power under strong light, please do not interval, at least 8 hours, the battery can be full. As we all know, more than eight hours of uninterrupted direct sunlight a day is still a bit difficult. Secondly, do not put the mobile power on the temperatureHigher inside the car, otherwise the battery life will be shortened, try not to shine sunlight through the glass to charge the mobile power supply, because the effect is not obvious.
3, the area of a solar panel is about 0.0089 square meters, which needs to be converted to about 80 hours of high noon sunshine at sea level to fill the solar panel of the charging bank, that is to say, if it is in Chengdu such a place where the sunshine is not very sufficient or under the conditions of street lights and LED lights mentioned in the propaganda, The time it takes to fill it up is ten or even a hundred times longer.
4. Charge the charging bankElectricity, general phone charger OK? Of course, but do not use the bad quality charger, because it takes a long time to charge the charging treasure, and the normal charger is also very hot, not to mention bad quality or miscellaneous brand.
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 to make itThe internal miniature precision motor is operated at high speed to generate electric energy, and the negative pulse of 12-8 milliseconds variable time depth generated according to the manual optimization program keeps the battery plate in the best state of electric energy to chemical energy charger.
If you can insist on shaking for three hours can certainly be full, the charger power must not be less than 5W.
Full of a 1000 mah estimate to shake a day. It can be considered for emergencies, but not for specialized work. If there are many outgoing phones, you can consider a multi-purpose power supply, that is, a power supply with a built-in polymer battery of about one thousand MA, and the price is not expensive, one thousandMah 20 yuan to 25 yuan, can charge mobile phones, can also charge MP3/4/5 or other small electronic products.
Here are a few of my top travel essentialsGood things: Chargers, 3-in-1 charging cable, portable charging bank these are essential things for travel, 3-in-1 charging cable is really good, you can charge three devices at the same time! The key is ten dollars very cheap! This charging bank is very small space saving, comes with four lines is also very convenient, 10000 MA capacity can be charged 2-3 times, enough for going out.
First of all, understand your own charging bank, understand what interfaces it has, and what functions it can complete. As you can see from the picture, my charging bank has two USB ports, indicating that it can charge two electronic devices at the same time; IN the middle of the two USB ports is a Micro usb port marked "IN", which is the place to charge the charging bank. Under the charging interface is the LED strong light for lighting. If there is no power on the subway, there is really no other way, the best way is to prepare two mobile phones, one mobile phone is out of power, and the other mobile phone can maintain the call status, or charge the mobile phone before getting on the subway.

How about a 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! It'll damage the panel if youIf the power is really not enough, the mobile power supply 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.

. 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 ordinary LED light, can be used as an emergency light. 3. Ultra-small, easy to carry, beautiful and generous, safe design, economic and practical.
Gently hand, easy charging. For you on the journey, in the commute, in all kinds of emergency time not to let the mobile phone battery delay your big event, let you lonely and boring. The product has excellent performanceMore, the on-site use of mobile phone charging demonstration, there is no disguise, buyers are very enthusiastic.
Under normal circumstances, ordinary mobile power supply is the best choice. Mobile power supply only needs to be charged for a few hours for the output device to use for a day, high efficiency, convenient, suitable for almost all people. Manual charger is suitable for camping in the wild or for a long time without power environment, low efficiency, poor stability, inconvenient use.
