Why are shared power banks appearing on the streets of Kunming?

Reportedly, a small power bank rental device called “Cloud Charge Bar” recently appeared in Kunming. The device is equipped with “Cloud Charge Bar” and “power bank self-service rental, no need to purchase data. "printed on it Line" and other words.

According to visits to several rental points, it was found that there are 3 different equipment models: large indoor terminal equipment, accommodating 90 portable power banks, mainly distributed in * * hospitals and other places; outdoor solar Terminal equipment can accommodate 90 portable power banks, mainly distributed in scenic locations; the mini terminal equipment can accommodate 10 portable power banks, mainly distributed in restaurants, etc.

Ms. He, who uses a shared power bank, said: “This is the pFirst time using it, and charging is pretty fast. The data cable is on the power bank, and this may be the case. used with Android and Apple devices. It took me half an hour to charge my phone. When it's fully charged, I can put it back into the nearest outlet. bank with me when I go out. It's really practical. get meal coupons, you can use it to take the subway or take the bus, you can watch TV series to chase stars, and you can also browse the news... ·With so many apps, suddenly found that the battery was The phone was almost exhausted, so a power bank came into being!

Power bank is very common, there are ordinary chargers on the market . Which is better, a cell phone or a solar power bank. ?

Let's look at the similarities first. The two apartmentsThey can directly charge mobile devices and have their own energy storage units, which can meet the charging needs of various digital products such as mobile phones, iPads and PSPs, which are common in the market today. 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 does not est 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, an ordinary power bank 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. The solar power bank is more environmentally friendly, providing electricity when there is light, breaking ainsi traditional mobile power supply. Charging is limited, but the required support is the sun, so charging is relatively slow. The power bank 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, the author still prefers solar power banks, mainly for convenience, environmental protection and energy saving.

How about solar power bank 2

Solar 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 26hours 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.
