Mobile phones are equipped with solar cells.
In 2009, Samsung launched the world's first solar cell phone, the Guru E1107. This phone can charge the battery via the solar panel on the back, but the efficiency is not high. 1 hour exposure to sunlight Can only hold a call for 5-10 minutes.
Guru E1107 is not Samsung's only solar phone. At the end of 2009, Samsung again launched a solar-powered mobile phone called Blue Earth. Although the charging efficiency has not been significantly improved, this product has added network access functions, allowing users to view social networks, web pages and even watch. videos.
Will solar power banks be more popular than wireless power banks
Advantages: Easy to use If you have your own office or bathroom study, the feeling of recharging is never to be expected. timeis first class Awesome. Additionally, since both WPC and PMA charging protocols are supported, you don't need to purchase an official wireless charger. You can use it if you buy one for tens of yuan on Taobao.
Disadvantage, charging is a bit slow because wireless charging conversion will cause losses. A little hot. I can no longer play with my phone while charging.
Wireless charger refers to a device that uses the principle of electromagnetic wave induction for charging. The principle is similar to that of a transformer. There is a coil at each of the transmitting and receiving ends. The transmission end coil is connected to a wired power supply to generate an electromagnetic signal. The receiving end coil detects the electromagnetic signal at the transmitting end and generates current to charge the battery. During the procharging process, there is a lot of radiation, and the charging efficiency is not high.
The difference between wireless chargers and wired chargers:
Difference 1, charging method: the wireless charger needs to charge the iPhone in the case first. charging protection, then place the protective case on it. On the induction base, then connect the induction base to the power socket, then plug in the power socket.
Difference two, connecting devices: When the iPhone is in wireless charging mode, the first step is to take out the charged iPhone in the charging protective case, the second step is to connect the mini USB, and finally the Mini USB is connected to the device. When charging the iPhone on the power adapter, simply remove the USB port from the adapter and connect the devices.
Difference 3: Convenience: When the phone is charging, a call comese but it is not practical to answer it in some specific situations. This is where the convenience of wireless chargers comes into play. Simply pick up the charging case and move it to any location that allows users to answer calls. If it is a wired charger, you need to unplug the data cable. To connect and charge, you need to reconnect the data cable. At this point, the wireless charger only needs to place the phone on the sensor to charge.
Difference four, charging efficiency: When the charging time is the same, the power after charging by a commonly used wired battery charger is 93%, and the power after charging by a wireless charger is by 88%. Clearly, there are still gaps in the charging efficiency of wireless chargers and there is still room to improve the technology.
Mobile solar power supplies are more efficientaces than wireless ones, but the current power bank market is in chaos and solar power banks are also mixed. When choosing a solar power bank, pay attention to the battery chip area, which depends on whether it can charge a mobile phone under different light intensities. Cell phone chargers are usually 5V, 1A or 5W, so if you only have a cell phone sized battery chip, basically you don't need to wait until you can load the machine. Additionally, there are cases where the solar charger battery cells and energy storage battery are integrated. This product poses certain safety risks. After being exposed to the sun for several hours, the temperature of the battery cells can reach 6 or 70°C. , and the safe charging of lithium batteries. The temperature is between 0and 45℃. When the battery area is sufficient and the circuit design is reasonable, a solar charger is a very good choice. When you are short of power, as long as the light intensity is sufficient, it can be used in an emergency. can also equip ordinary power bank to store electricity. You can also use a power bank to charge at night. Especially when you go without electricity for a long time, a small power bank has little power and has a large capacity like a brick, so a solar charger is a good choice. And it's quite green. It is recommended to read more reviews before purchasing and choose the right product
. Question: Enthusiastic netizens replied: 1. When charging a mobile phone for the first time, charge it for as long as possible, generally 12 hours is best. After a load greater than a certain times, if you do not remove the charger, the system will not only stop charging, but also start a discharge-charge cycle. However, it harms the battery life of the mobile. phone charger and cell phone. 2. Avoid overloading. Overcharging the battery to more than 100. Since overcharging lithium batteries is dangerous, if you use a "cradle charger that can overcharge" and purchase a "crude quality, circuit board protected lithium battery", then charging is like waiting for a fire 3. Do not use when the ! the battery is exposed to high temperatures or severe cold, such as during summer heatwaves, the phone should not be left in the car to be exposed to the scorching sun or placed in an air-conditioned room where the air conditioner is blowing; directly. When charging, it is normal for the battery to heat up a little, but this should not make it hot at all.sleep. In order to avoid this situation, Jinghao should charge at room temperature (around 26 degrees) and not cover the phone with anything. If abnormal conditions such as overheating or smoke occur during charging, the charger should not be unplugged immediately; cables from different manufacturers. 4. Keep away from any metal objects. Cell phone batteries should avoid contact with gold and silver jewelry, watches, metal ornaments, pins, etc., just in case. Because when the cell phone battery plug touches a conductor, a short circuit occurs, causing the battery temperature to rise. The high temperature volatilizes the chemicals in the battery, producing very dangerous gases and even explosions in severe cases. . 5. Do not charge before the battery is exhausted, this will not only damagethe battery, but would also reduce its lifespan. The correct method should be to recharge when the power runs out. Give some small photovoltaic gifts, such as portable lights, car decorations, solar power banks, etc. Solar energy is a trend of the future and solar products are now too. It's very trendy, ecological and practical! The key is that it is more innovative and saves face when removed. I hope you will adopt it, thank you! ~
1. When the external battery is not in use, it should not be placed in a high temperature place, let alone water. It must be placed in a dry and ventilated place. 2. The power bank must not be disassembled or modified without authorization to avoid unnecessary hidden dangers. 3. Pay attention to waterproof, dustproof, shockproof and dropproof. Fourth, you cannot use magazines and dechaincompatible sources. They can only be used if they match your power bank. 5. The rated voltage of digital equipment should be confirmed before use. The input voltage should not be higher or lower than the rated voltage to avoid damage to the equipment.
My friend recently purchased a quadruple power battery, which is very efficient and capable of charging cell phones using solar energy. This is my suggestion
