Don't be fooled by the title party anymore! What conditions do solar fast charging need to meet? Key information you need to know!

Friends who like to read martial arts novels may know a classic saying: martial arts in the world, only fast can not break! But in the scorching summer, in the face of the scorching sun, donkey friends bask in the sun while charging with solar energy, feeling unbearably hot! How can mobile phones, iPads, charging treasures and other electronic devices be powered on quickly? I think it's the same reason: Outdoor battery renewal is the only way to keep it fast!

There are various fast charging technologies on the market, but can solar power alone support fast charging? Do you really know about solar fast charging? By reading this article to introduce the knowledge of solar energy and fast charging, it may help you avoid a lot of waste of money!

No one party is willing to pay the "patent fee" for the other party, leading to a four-party competition for the development of fast charging technology.

Since the advertisement of ViVO mobile phone "charge for 5 minutes, talk for half an hour" has become widely known, OPPO flash charging has brought the charging of mobile phones into the era of fast charging! Since then, various mobile phone manufacturers have developed their own fast charging protocols: Huawei's super fast charging, Qualcomm's QC3.0, and Apple's PD. Since then, fast charging technology has formed a four-legged situation! Why do you say "four-legged confrontation"? Because the fast charging technologies of different manufacturers are not necessarily compatible with each other, the effect of fast charging cannot be achieved. Maybe in life, you will find that when you use ViVO's fast charging adapter to charge Huawei's mobile phone, you will find that the mobile phone is not displayed on the fast charge; the same reason, using Huawei's fast charging adapter to charge OPPO, you can't achieve flash charging! The reason for this is simple, because the two companies are unwilling to pay each other's patent fees, so they do not support each other's fast charging technology.

ViVO's flash charge is 5V/4A, Huawei's super fast charge is: 5V/4.5A or 4.5V/5A, QC3.0 is 12V/2A, 9V/2A, 5V/3A, PD fast charge is 20V/2.25A, 15V/3A, 12V/3A, 9V/3A, 5V/3A. Although the four fast charging protocols are different, under normal circumstances, it is still possible to charge each other through 5V/2A. This is our commonly used power consumption speed!

In order to achieve solar fast charging, mobile phone charging treasure and other devices also need to be compatible with the corresponding fast charging protocol.

Many people mistakenly believe that as long as solar charging supports fast charging, they can quickly charge electronic products such as mobile phones, tablets, and power banks! But in fact, it's not! First of all, the realization of fast charging by solar energy has a lot to do with the area of the solar panel. Only with a large enough area can the solar panel absorb more sunlight to achieve the required fast charging. For example: a solar charger with only 4 solar panels and a power of 28W, in the case of excluding various losses during the charging process, the actual available power is only 16W, while the general QC3.0 fast charging requires 18W , so even in sunny conditions, a solar charger with a rated power of 28W cannot achieve fast charging. Talk about spring and winter weather. Therefore, to achieve stable fast charging, the rated power of the solar panel should be set above 40W.

In fact, solar energy can be used to achieve fast charging. If the mobile phone or power bank does not support fast charging, it can only use the commonly used 5V/2A charging speed. Currently on the market, except for OPPO's flash charging, other fast charging technologies cannot allow mobile phones to achieve fast charging. Most of the technologies such as QC3.0, Huawei fast charging, and PD fast charging can realize 18W fast charging between each other. The 9V/2A fast charging and 18W two-way fast charging advertised on the Internet belong to this type.

Fast charging solar charger with power storage function, fast charging is meaningless

In order to allow the solar panel with a small area to also have the fast charging function, some merchants add a QC3. Charge. This kind of fast charging is actually meaningless, because it is not the solar panels that are fast charging, but the stored battery cells that are fast charging. In fact, this kind of fast charging is not really fast charging, because the power generated by the 3 solar panels cannot meet the demand of 18W fast charging, that is to say, the power generated by solar energy is much lower than that of fast charging of batteries. Need to consume electricity. This kind of fast charging is just a concept, and it only has a fast charging port.


Through the above description, I believe that more outdoor travel enthusiasts will have a deeper understanding of solar fast charging! Only by further understanding can we solve the problem of solar fast charging! Perhaps for you who are considering buying a fast-charging solar charger, you can save more than just money! Solar energy can achieve fast charging, the key is to understand and choose!
