The difference between a solar power bank and a solar charger is that the former machine has a battery inside and can produce at a constant rate, so the power of the solar battery may be slightly lower and the battery can be used to charge the mobile phone when the light is insufficient. The latter does not have its own battery and simply charges when there is light and stops when there is no light, so the design power is relatively high.
Is solar power bank real? easy to use?
The meaning of light energy charging of the scale is that the scale can convert solar energy into electrical energy through solar charging device, and then store the electrical energy in the battery for daily use. This charging method is convenient for users without worrying about power issues.It should be noted that when charging under strong light, you should continue to charge continuously until it is fully charged, and avoid placing the scale in a place with excessive temperature to avoid affecting the duration battery life.
How to charge the battery with solar energy
That's true, but the solar power bank is not very easy to use.
The power of solar energy mainly depends on the light reception area. In actual use, the charging status of the mobile solar power supply itself is closely related to the weather. The area of a mobile solar power supply is only 0.01 square meters.
Under sufficient sunlight, it can emit up to 1.4 watts of electricity. It takes 26 hours to fully charge a power supply with a capacity of 10,000 mAh. This is the best estimate, and it actually takes much longere time. only that.
Remarks
1. Please try to keep the storage temperature of the product between 15℃ and 25℃.
2. If the product is used in an overheated or cold environment, it may be temporarily unusable even if it has power remaining.
3. Do not throw the product into a fire as it may explode.
4. Please do not expose the product to liquid or suffer significant impact.
What is practical solar power bank, basic knowledge of solar power bank
Batteries used in cars are lead-acid starting batteries and their main purpose is to When the car starts, it supplies electrical energy to the starter motor. It is characterized by a surface charge, a surface discharge and a self-discharge. Therefore, the battery must remain fully charged during use, otherwise its lifespan will be considerably shortened.reduced ent.
The nominal voltage of the car battery is 12 V, but it is actually higher, around 12.5 V. It will be difficult to start the car; if the voltage drops to around 10.9 V, the battery is almost completely exhausted. Thus, the so-called battery is discharged, not because the battery voltage has dropped to 0 V, but because the remaining power is not sufficient to support the normal operation of an efficient circuit. Generally speaking, when the battery is completely discharged and then recharged, it can only be charged to 80% of its original capacity at most; if there are more than three complete discharges, the battery will be difficult to recover. Therefore, excessive discharge will cause serious damage to the battery.
In addition, another important characteristic of lead-acid batteries is self-discharge. Even if there are no electrical components connected or any load, approximately 1% ofelectricity will be lost every day, which is called the "self-discharge rate". Its size is directly linked to the quality of the battery. battery, the purer the electrolyte, the lower the self-discharge rate.
If the car is stopped for a long time, the battery will automatically discharge and the voltage will gradually drop. Generally, it will be difficult to start the car if it is stopped for about half a month. If it is stopped for more than three months, the battery power will completely decrease. If the battery connections are not disconnected and there are still functioning electrical components on the car, the process will be shorter. At this time, the electrolyte will crystallize on the plates, causing irreversible damage to the battery, and the battery life will be greatly shortened.
Thus, for a vehicle parked for a long time, it is preferable to unplug theou cables from the battery and start it every ten days or so, running it for more than half an hour each time to let the generator charge the battery to prevent the battery power from dropping too much, this which can effectively extend battery life.
To put it simply, solar modules are not just decorations, they can in fact be charged by sunlight. The ordinary power bank with a battery board sold on Taobao usually needs to be exposed to sunlight for several days to be fully charged. The battery capacity is said to be very large, but in fact it is not. Solar batteries are generally used for solar and commercial charging. Don't think that solar batteries can only be charged by the sun. Some people have the habit of leaving their external battery in the car to recharge itin the sun, which is very dangerous, especially in summer, when the temperature inside the car is 60 or 70 degrees Celsius, which can easily lead to hidden dangers. The one below is a quad power battery, with four battery panels and 4,000 mAh. It can be completely tanned in about 4 hours under sufficient sunlight.
