The batteries of mobile phones and computers are getting bigger and bigger, and the fast charging power is getting higher and higher, and the charging speed of many mobile power banks before is difficult to meet my current needs, and it is necessary to charge multiple devices at the same time, and at least two mobile phones and one computer should be brought when going out. 
I finally chose Zimi Z130, a 2000mAh PD high-power mobile power bank, Zimi is a world-renowned digital brand created in 2010, with mature mobile fast charging solutions, here is a detailed introduction to this power bank. This mobile power bank is a gray Z130, the design is very simple, the shell is made of fireproof aluminum alloy, the size of the palm is only about 425 grams, and the integrated aluminum alloy is rounded and has no edges and corners, and it is not awkward at all;On the front is the logo of Zimi, with a maximum power output specification of 130W. 
In terms of interfaces, it is equipped with 2C+1A as standard, and the three interfaces are fast charging, of which Type-C1 supports up to 100W, which can charge laptops and mobile phones, supports PD and other fast charging technologies, and can take this one on a business trip, and it can be on the plane in accordance with aviation regulations, and there is an LED screen on the far left, which can display information such as power fast charging protocol, which is still very practical. 
The basic interface with the power distribution can be seen in the following table, with C1 and C2 ports at the same time, as well as the state of three ports for full use, the maximum working power of the mobile power supply can be reached 130W. 
There is a button on the right side, in addition to power on/off, double click this button to activate the low-current charging mode, which is suitable for charging devices such as Bluetooth headsets for about 2A. 
On the back, there are all the electrical parameters of this power bank, 130W fully compatible fast charging power bank, which also explains the main features of this product, and it is also marked;You can only use the C1 port to charge the power bank, don't make a mistake about this. 
He was also given 3 charging cables, of which the black one supports up to 100W charging, and the other two dual Cs support 60W, Apple Lightning is the standard line, and there is also a Zimi RH-PD33W gallium nitride fast charging charger, I was surprised to get it This is also too small, at least 30% smaller than other chargers. 
It is also a purple meter, which can be used in Apple's 8th generation to the latest 15th generation, all Android models, and no heating is felt during charging, which should be related to the use of fifth-generation gallium nitride technology, and the use of intelligent temperature control and low-temperature fast charging technology, which will not hurt the mobile phone, don't look at such a small charging head, support PD FCP QC fully compatible with multi-protocol fast charging. 
Charge the power bank with this charger, 1It can be fully charged in about 5 hours. 
Through the ammeter, it can be seen that the nominal maximum of 30W has been reached, because the power bank is close to being full, which is slightly lowered, and the protocol aspect looks like the PD fast charging is activated. 
We choose a power bank, we must not only look at the appearance and interface, the battery and control chip is its soul, the car cell battery should be the best, this also uses the 21700 lithium-ion battery of the vehicle specification grade, Nanxin 2001 chip system, can resist falling high temperatures, cycle 800 times to think about it can be used for many years, the national standard only requires 300 times.
Of course, safety is more important,Multiple protection technologies are all arranged,Aluminum alloy shell extrusion resistance,Fire and high temperature resistance,Overcharge, overdischarge, short circuit and other problems also have the desired protection measures,Now notebooks generally use65W charging standard,Basically using PD,According to Zimi's official news,Most brands and models of notebooks on the market have been tested and matched,My HP notebook,Charging with it is also very fast,There is no difference between using an external power supply。
Let's take a look at the fast charging protocols supported by the three interfaces,At present, the most mainstream ones are supported,Apple、Huawei、Honor and Xiaomi, these mainstream ones can be used,OV series can go VOOC or PD,I tested three mobile phones,iPhone15 Pro Max,OnePlus12 and Huawei Mate X5,Fast charging can be activated,The gap between the charging speed and the original adapter is very small,Of course, they are all connected to the C1 interface。 The most common devices I use on business trips are 2 mobile phones, a laptop or tablet, and if there is no power supply, this power bank can meet the needs of charging 3 devices once.
All in all, this Zimi power bank provides portable charging for my device when I go out, and solves my power needs anytime, anywhere. In case of emergency, it can avoid the power failure of the equipment, maintain communication during the journey, and work and study Xi without restrictions. Lightweight and portable, it has become an indispensable convenience tool for me.
