In daily life, for those who are light mobile phone dependents, a 10000mAh power bank can guarantee at least one charge. Those who are moderately dependent on mobile phones can consider a 20000mAh power bank that can charge their mobile phones 3-4 times.
Capacity is not the bigger the better. Unless you have special needs for long battery life (such as camping in the wild), a large capacity of more than 30000mAh can also be excluded.
This is because the size, weight and price of the power bank generally increase with the increase of the capacity. It is worth mentioning that if you travel frequently and need to fly back and forth, you need to pay extra attention to the capacity of the power bank.
Listen to me, the power bank must choose fast charging power bank
The capacity determines the basic battery life of the power bank, and the fast charging function determines the speed of charging the mobile phone, which is related to the user experience. The fast charging power bank is not a few dollars more valuable than ordinary charging, but the experience of use is several blocks away from the ordinary power bank. Nowadays, it is standard for mobile phones to support fast charging, so listen to me, charging treasures must buy fast charging! However, the “fast charging power bank” still cannot close your eyes, you must see the “fast charging agreement” clearly.
We can determine such a principle: only the fast charging protocol that is compatible with the mobile phone and the power bank can trigger the fast charging mode. Moreover, no matter how much charging power the fast charging power bank can provide at the highest, in fact, the mobile phone has the final say.
Therefore, if the fast charging protocol is not compatible, even if you use a 125W super flash charging power bank, you can still charge 5V 0.5A at a turtle speed.
However, the number of fast charging protocols is so large that it can persuade every user who intends to choose a power bank well.
There are not only public protocols released by industry leaders such as USB IF and Qualcomm, but also a bunch of private protocols developed by mobile phone manufacturers. These agreements have caused serious selection difficulties for ordinary people who do not have this knowledge.
Don’t worry, here we tell you directly how to buy it.
Android users: preferred original fast charging power bank
If you are an Android user, we strongly recommend that you prefer the original fast charging power bank.
First, for ordinary people, it is very easy to step on the pit to distinguish the protocol compatibility of the device.
Let’s take Qualcomm’s QC protocol as an example. In addition to Huawei mobile phones, most of the domestic Android mobile phones are equipped with Qualcomm’s Snapdragon processors, while supporting their own private protocols, many are compatible with Qualcomm’s QC protocols.
Because, the QC protocol also has its own version compatibility issues!
QC3.0 is backward compatible with QC2.0 and QC1.0; QC4.0 supports USB PD but is not compatible with QC2.0, QC3.0; QC4.0+ supports QC2.0, QC3.0, USB PD.
Without knowing the compatibility of the fast charging protocol of your mobile phone, you may have bought a power bank that charges very slowly.
Second, various mobile phone manufacturers are only compatible with the lower power of the USB PD protocol.
In recent years, there has been a trend of compatibility between some protocols. For example, the public protocol USB PD 3.0 incorporates Qualcomm’s QC, MediaTek’s PE, Huawei, and OPPO’s private protocols.
Therefore, there is indeed such a fast charging power bank, which can be used by Huawei, Xiaomi, OPPO, Samsung, and Apple. For example: https://www.growjaa.com/gan-pd-charger-100w-turbo-4-ports-gan-wall-charger/
But what the power bank merchants don’t tell you is that each mobile phone manufacturer is only compatible with the 18W power of the USB PD protocol – this is indeed “fast charging”, but it is not enough to compare with the original charging equipment of the mobile phone manufacturer. The power of 18W is not comparable to the fast charging level of OPPO mobile phones 7 years ago.
To sum up, unless you have general needs, such as charging Switch, laptops, etc., you can consider buying a high-power PD protocol power bank.If not, it will be faster to use the fast charging original power bank
