At present, the charging treasure is almost a necessary electronic digital product for everyone, but the current model, price, and quality of the charging treasure are uneven, and the selection is also dazzling, and there is no way to start. So, how can we choose a charging treasure that suits us?
Say this first for everyone to carry out simple science, let everyone have a simple understanding of the charging treasure, so that they choose a charging treasure other than my recommendation today also has a reference, to avoid stepping on the pit!
The battery cell of the charging treasure can be simply regarded as a battery and a place to store electricity. The battery cell is the most important and core component of the charging treasure, which is directly related to the safety of the charging treasure.
At present, the commonly used batteries on the market can be divided into two categories: 18650 batteries and lithium polymer batteries.

18650 battery cell: mature technology, low cost, large output. Some Tesla electric vehicles and heavy laptops are used in 18650 batteries, and the full charge and discharge life is about 500 times.
Polymer batteries: Polymer batteries are considered to be the trend of the future, the advantage is that they are small in size and can be made into various shapes, so the batteries used in general mobile phones are used. This battery will last a little longer, around 700-800 times.
18650 Cell Classification:
Imported 18650 battery cell: Generally used are Sanyo, Samsung, Panasonic, Sony and other manufacturers produce relatively high product quality. Domestic 18650 battery cell: mainly PRODUCED, BAK, Bangkai, Shenli and other domestic manufacturers, but the overall level and foreign countries have a certain gap Dismantling the machine 18650 battery cell: Generally, this kind of battery cell is a mobile power supply that is dismantled from the old products in the past and assembled, and there are certain hidden dangers in terms of safety.
Polymer cell classification:
Class A: These polymer batteries are new polymer batteries of the best quality, without any abnormalities. Class B: This type of cell has slight problems in appearance, capacity, voltage or other parameters. If a Class A cell is in stock for too long, it is often referred to as a B product. C grade: This type of battery is usually eliminated, the quality is very poor, usually in the appearance, capacity, voltage and other indicators are not qualified. There are security implications.
Since the battery cell of the charging treasure is related to the safety of the charging treasure, but the battery of the charging treasure we cannot see, how should we buy it?
The answer is: buy directly from the big brands of the regular platform! Because they are very guaranteed in terms of quality safety and after-sales! Don't buy some unreliable shop copycat goods or unlicensed stalls on the side of the road for cheap. As long as a good charging treasure is used properly, the minimum use of more than 5 years is no problem, do not save this money!
At present, we still have many common and more reliable charging treasure brands, such as: Huawei, Greenlink, ANKER, OPPO, Xiaomi, Pinsheng, Philips, Patriot, Scud, Yubo, Romashi, Bess and so on.
This is an important parameter of the charging treasure. In simple terms, the charging treasure capacity (lithium battery capacity) refers to how much power the charging treasure can store, and the rated capacity represents how much power it can discharge. And the ratio between them is the conversion rate of many charging treasure promotional pages!
In fact, we can simply understand that any charging treasure will have a conversion rate, and the level of conversion rate can reflect the actual output capacity of the charging treasure to the device, and the loss of the charging treasure storage and charging process. The higher the conversion rate, the better the charging treasure. If you see a charging treasure that is not marked with a rated capacity, most of them are catty.
When choosing a charging treasure, we only need to look at the rated capacity of the charging treasure, that is to say, it is the power that determines the real charge of the mobile phone. For example, my mobile phone battery capacity is 4000 mAh, the rated capacity of the charging treasure is 12000 mAh, in theory, in the mobile phone is not charged to full power, it is only 3 times. But because many of us are used, generally when the mobile phone is less than 20% to indicate that the battery is low, it will start charging, so a fully charged treasure can charge the mobile phone 3-4 times.
Needless to say, the interface selection is mainly to facilitate the charging treasure and the charging treasure to charge the device, and the input interface for charging the charging treasure has three types: Type-C, Micro-USB and Lightning. In addition to the most basic USB, the charging treasure also has a Type-C supported in the last two years. Basically, the Type-C interface on the charging treasure is bidirectional, which means that it can be punched and placed!
This is my own use of the Beth charging treasure, it can be said that basically the full interface type of charging treasure, that is to say, no matter which mobile phone you use, only need an original line, both to charge the mobile phone and to charge the charging treasure.
Now more and more mobile phones support the function of fast charging, so when choosing a charging treasure, you can choose a suitable charging treasure according to your own mobile phone, which is simply to see whether the fast charging protocol supported by the charging treasure and the one of your own mobile phones can be right.
The most common fast charging protocol on the market is the PD fast charging protocol. PD fast charging protocol covers Qualcomm, MTK, Huawei, OPPO before their own protocols, popularity is the best of many fast charging protocols, but it should be noted that the PD fast charging protocol must use Type-C output, so buy PD protocol charging treasure, you must remember to buy Type-C data cable!
The current fast charging protocol on the market:
1. PD fast charging protocol, full name "USB Power Delivery" power transfer protocol. There are currently three versions of the PD protocol, PD1.0, PD2.0, PD3.0, and the latest PD 3.0 protocol supports Qualcomm's QC fast charging protocol. Any charger that supports the USB-PD protocol must be type-C output. (Type-C is the kind that can be inserted on both the front and back of the phone) 2, Qualcomm QC fast charge: In 2013, Qualcomm released the QC1 protocol, and then after experiencing QC 2, QC 3, QC 4, QC 4 + versions, on July 28 of this year, Qualcomm announced the launch of the QC5 that supports up to 100W charging power, and further compatible with PD. 3, MediaTek PE fast charge: full name: MTP Pump Express Plus is currently the latest PE3.0 protocol launched in 16 years, the maximum charging power of 34.8w, the market use is relatively small. 4, mobile phone manufacturers private fast charging protocol: OPPO's VOOC flash charging, Super VOOC super flash charging technology, vivo's FlashCharge, OnePlus Dash, Huawei's FCP and SCP, Xiaomi's ChargeTurbo, Samsung's AFC, most of these fast chargers need special chargers and data lines.
Basically, it can be seen that buying a charging treasure now, it is best to buy a support PD fast charging protocol. For some special protocols, such as OPPO, VIVO and other proprietary protocols, let's first see if it is compatible with PD, QC protocol, if not compatible, may only be able to buy self-produced charging treasure to achieve fast charging. Of course, it does not mean that it is necessary to buy a charging treasure that matches the protocol, but this can give you the best experience.
First of all, the answer: Absolutely!
However, due to safety considerations, the aircraft still has requirements for the capacity of the charging treasure it carries, which can mainly summarize the following points
Charging treasures of 27,000 mAh and below can be taken directly on the plane
Charging treasures ranging from 27,000 mAh to 43,000 mAh require approval to be carried on board
Charging treasures of 43,000 mAh and above are not allowed to be taken on the plane
Therefore, for the common 10,000, 20,000 mAh charging treasure, there is no need to worry about these problems, if it is a 30,000 mAh charging treasure, it needs to be approved by the airline.
In a word, buy the best within budget! Specifically, I personally feel that the charging treasure is bought once for many years, and most of the charging treasures on the market do not exceed 300 yuan, and it is good to buy a charging treasure once in place. Of course, if there is a requirement for portability, it is a different matter.
Portability is based on your own needs and usage scenarios, such as whether you usually carry the charging treasure to travel, or travel, party, etc., and you need to charge the equipment to buy the charging treasure. If you are just using it purely on the road, buying a smaller charging treasure is not the wisest choice.
After reading the above recommendations, you should have a general understanding of the charging treasure and its purchase. Below I will recommend to you the charging treasure that I have used and the current quality and reputation are good.
Usage scenarios: short-term travel, leisure shopping

In terms of fast charging, it supports 20W two-way flash charging, so there is no problem with Huawei Xiaomi mobile phone fast charging.
Philips 20000mAh charging treasure
Recommended reason: It may be the most MINI charging treasure of the current 20,000 mAh charging treasure. However, although the figure is small, but the appearance value is also very high, two USB interfaces and a C port, and also supports the fast charging protocol has to support Apple's PD fast charging, Huawei's 22.5W SCP fast charging, and there is also an LED display on the side to display the power.
The above recommendations are only a few representative charging treasures, in fact, there are many charging treasures that can really be selected. For example, the above-mentioned VIVO, OPPO and other manufacturers to support their own fast charging protocol of the charging treasure is also very good, is also the first choice for the use of these two mobile phones charging treasure. As I said in popular science, charging treasure actually chooses a formal platform and a reliable brand. According to your budget and needs, you can buy flexibly!
