How about a solar power bank 1
Because now cell phones can be used as navigation, you can use it to get coupons for meals, you can use it to take the subway or take the bus, you can watch serial TV to chase the stars, and you can also browse the news...so after using many applications, I suddenly found that the battery was low. The phone was out of charge, so power banks came into existence!
< p> Power banks are very common. There are ordinary power banks on the market. There is also a solar power bank, which is better between the two?Let's see the commonalities first. Both devices can directly charge mobile devices and have their own energy storage units, which can meet the charging needs of various digital products.ues such as mobile phones, iPads and PSPs, which are common in the market today. There isn't much of a price difference between the two. Taking 20,000 mAh as an example, both cost about 100 yuan.
Let's look at the difference between the two.
Different forms of charging: Solar power banks convert solar energy into electrical energy and store it in batteries. Common power banks are now primarily based on liquid lithium-ion batteries, which store electricity and boost voltage. management is integrated, charging comes from the domestic sector.
The charging efficiency is different:
The conversion rate of solar power bank cells is generally only about 16%. In theory, this may be the case. fully charged with 12 hours of sunshine, but in practice For a longer period, a bankOrdinary power supply can be fully charged in about 12 hours, and the conversion efficiency does not exist.
Convenience is different:
If the user stays outside for a long time, it is difficult to get recharge opportunities with banks Ordinary power banks, and power banks will also run out of power, but solar power banks are different. As long as there is light, you can charge the power bank, which is very convenient.
That said, which one is better?
It can only be said that both have their own merits. Solar power banks are more environmentally friendly: they produce electricity when there is light, thus eliminating the constraints of traditional mobile electric charging. However, the required medium is the sun, so charging is relatively slow. The food banktation charges quickly, so you don't have to worry about lack of sunlight, but the power bank may run out of power if you stay outside for a long time. If I have to compare, I always prefer solar power banks, mainly for convenience, environmental protection and energy saving reasons.

How about solar power bank 2Solar power bank is not 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 longer. than 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 too cold environment, even if it has power remaining, it may be temporarily unable to operate.
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
It is relatively reliable and there is no danger. Solar power banks came into existence in 2012 and some people were developing products at that time. The goal is to convert solar energy into electrical energy. After testing, our current technology has not reached this level. A 5000 mAh product requires 16 days of exposure to sunlight to charge.
But I don't recommend buying it. For pure solar power, if there is another option, you can choose an adapter to charge the power supply.on mobile, maybe you can consider it. However, if an adapter can solve the problem of charging, why would you buy one with a solar feature that looks useful but isn't actually used? And for this you have to pay money.
Generally speaking, you can just buy a regular mobile power supply. Use an adapter to convert electrical energy into chemical energy in the battery, and use mobile power to charge your cell phone when needed.
The solar power bank converts solar energy into electrical energy to charge the power bank's battery, and the battery then charges your cell phone. In other words, when you plug in your cell phone, it shows that it is activated. is charging, it's not the solar energy that charges you, but it's the battery inside that charges you. Small solar panels do notusually don't dare to get into big trouble, that's what you see. The drum part is relatively uneven. Some have low charging and discharging efficiency, others have short life due to low charging and discharging times, and there are also safety hazards such as high temperatures.
