Because I have been in contact with various Type-C devices recently, I also have a lot of interest in Type-C. Type-C can achieve many functions, the most powerful one belongs to a Type-C implementation of a complete docking station program, but because the current Type-C docking station prices are relatively high, so I have not yet reached the relevant Equipment (mainly because of poverty). The author's greatest interest is to use a Type-C interface to achieve a charger ideal for charging with a mobile computer.
Previously there was a charger that claimed to be able to charge both mobile phones and computers. However, since it supports QC, it does not support PD2.0, so it can only be used for mobile phones that support QC, some Apple computers and Huawei Matebook and other low-power products. , was later taken away by colleagues. This time, I saw the purple rice No. 10 mobile power on crowdfunding line, claiming to support PD2.0, that is to say, it can charge most computers that support Type-C charging, so apart from anything else, I would like to buy a try. how is it.
Prior to the purchase of crowdfunding products, due to buy earlier, so get the lowest 169 files. It seems that there is no official sale, so add a crowdfunding card.
Crowdfunding products require long waits. Orders were placed last year and shipments did not begin until mid-January. Fortunately, they were received by the year before. On the packaging, this product is similar to the packaging of purple rice, and they all have the same design style as the millet line. On the back, there is also the anti-counterfeiting label of the millet line.
Open the packaging, it should be said that the overall level of exquisite feeling of this package is not enough, fortunately protective measures are also good, there is a layer of sponge inside the lid.
The first impression first appeared was that the product was quite large. Although the rated capacity of 2WmAh allowed the author to have a basic estimate of its size, the overall situation was still beyond my imagination. Positive purple rice LOGO design is quite special.
All accessories are only mobile power, a Micro-USB, Type-C dual data cable, a manual. As a mobile power defined as a multi-purpose, the line without a C2C is really unjustified. At present, the cost of C2C data cables that support lightning is still close to 30, and it is estimated that it is because of cost reasons.
There is nothing to say about the wire. The wire seems to have been on the Xiaomi Mall before, and there are many similar products on the market.
The main body of the mobile power adopts an all-aluminum alloy shell, and the surface is sandblasted to ensure a good feel and excellent heat dissipation.
On the back there are detailed parameters, including USB-A and Type-C output currents and support protocols. Among them, USB-A supports up to 12V 1.5A, Type-C supports up to 20V2A, which is the highest 45W output. The input part is also Type-C, up to 40W, provided that there is a charger that supports PD2.0.
The only button is on the side, the right side of the button is the four battery indicator, the left side of a larger LED, the USB HUB function indicator. The factory power is about 50%, which is also the more common lithium factory power.
The USB HUB's indicator light is very large and the brightness is much higher. If you look directly at the HUB, you may still be dazzled.
At the top are three parallel ports, two USB-As on the two sides and one Type-C in the middle. In theory, up to three simultaneous outputs are supported.
Carefully observe that there is a sign above the Type-C indicating that the Type-C interface supports bi-directional charging, which can either charge the mobile power supply or charge other devices. This is one of the most important features of the Type-C.
Take the two mobile power sources at hand to make a volume comparison. The two mobile power sources have the same capacity. One is a 3-cell, and the other is a 4-cell cell. You can see the width of the purple rice No. 10 mobile power source and the 4-cell cell. The closeness, thus judging the internal battery arrangement should be composed of 4 batteries + 2 batteries, the remaining space is used to place the circuit board, after all, this circuit board is also more complicated than the traditional mobile power supply.
A mobile power, the appearance of the part did not look good. Test the charging ability below. Since the author does not currently support QC equipment, he uses ZUK Z2 to test his regular 5V output. The 5V can output up to about 2.2A of current, which is the highest among the mobile powers I have ever seen, and the voltage is still stable at 4.9V, indicating that the line loss compensation is still relatively high.
With other mobile power sources at hand, it can only reach a current of less than 2A, and the voltage is slightly lower.
The next most important part is charging the computer. To charge the computer, you must use the Type-C interface and you need a charging cable that supports the PD protocol. The common charging cable may not work. I use this kind of line, you can see this line interface after the position is relatively long, but there are two holes, the current double-headed Type-C line to support lightning and PD protocol are the case, if you need to buy Only need to pay attention to this connector will know.
The author's notebook is the ASUS TP301UA, which is widely used in the black sea.
Although this notebook has Type-C interface, but the pit father of Asus actually only supports USB3.0 protocol, so the charging is not hopeful ... ... actually measured it, no response at all charging, pay attention to look at the corner of the lower right corner of the computer The standard is still battery status.
Although the charging can not be used, but the function of the USB HUB is still supported, measured a USB3.0, normal speed 80 + U disk, USB HUB can only reach 30 + speed, prove that this product USB HUB is just USB2. 0 interface, the general use of a mouse is not a big problem, if you copy a large file or use USB3.0 interface faster.
Take my wife's ThinkPad New S2 to do a test. This computer was bought in August. It also has a Type-C interface.
ThinkPad is still relatively kind, equipped with a full-featured Type-C interface that supports video output and charging. Connected with a mobile power supply can be charged smoothly. Although the screen shows that it is not charging, it is also displayed after the plug-in...
Turn on the USB HUB and connect it to the mouse receiver. The same can be used to drive normal use.
However, I still encountered a problem, in order to facilitate the video output, I previously bought a millet's Type-C HDMI adapter. This adapter claims to support charging while switching, but after using the adapter, the notebook shows that the AC adapter is incorrect and cannot be charged. This is not known to be a problem with the adapter, or is it that the power of the mobile power supply is insufficient to drive the adapter and the computer at the same time?
For this product, it is basically able to achieve the official claimed features. There is definitely no problem with a mobile phone, and the USB HUB is still quite usable. As for charging a computer, it depends on whether the computer supports it. For the purchase proposal, if it is a new MacBook user, personal advice can still start with 200 yuan, after all, whether it is charging or the attached USB HUB is practical for the new MacBook. And if it is the user of Win system, not tangled in the number of USB ports, then this product is still somewhat tasteless, it is recommended to find out the type-C version of the computer and whether to support the charge, and then consider whether to start. Of course, if you are a heavy mobile power consumer who often runs outside, then this 2W capacity and 3 output is still believed to be helpful. If you can get it around 150, then with the common 2W mobile power supply There is no price difference, other features are equivalent to the delivery, nature is still quite cost-effective.
PS: There may be friends who are concerned about whether they can fly on the plane. They can definitely say yes. Its total energy is less than 100Wh, while the third gear of air traffic control is 100Wh, 100-160Wh and 160Wh respectively. Among them, the products below 100Wh can carry with them without being carried.
Practices sum up the advantages and disadvantages.
advantage:
1) Three outputs, and all support fast charging, which can meet the needs of many people at the same time.
2) It can charge a supported computer and expand the usage scenario.
3) The USB HUB function is basically customized for the latest MacBook, eliminating the need to buy an adapter.
Disadvantages:
1) The volume is too large. If 3+3 arrangement can be adopted and the volume of the circuit board is reduced, it is believed that the size can be further reduced.
2) The problem caused by large capacity is naturally slow charging. Theoretically, if the PD2.0-supported charger can be quickly charged, the current PD2.0-supported charger is too rare and the price is high. Has been to Lenovo X1 Carbon's supporting Type-C charger, 299 Dae ...
3) USB HUB only supports USB2.0 with some regrets.
