Violent Dismantler Part II: Another shuffle? MI millet mobile power 2 detailed performance analysis

Related to:

Xiaomi also released a mobile power source, which was named Xiaomi Mobile Power 2. Then the question came, what are the many mobile power sources released before?

When millet mobile power was released at that time was titled the price killer, then millet mobile power 2, is it also a price killer? Just look at the parameters, millet mobile power 2 and millet mobile power supply high version is simply a fight with their own products. In addition to the charging port, the two mobile power sources can be said to be carved out of one mold. However, millet mobile power supply with a high version of the price of 149 yuan, while the millet mobile power supply 2 for only 79 yuan . Is it really their own hanging products? What is the difference between them ?

And listen to the following decomposition, again before, Air04 or that sentence: a sub-price goods, constant ancient truth . If you think there are cheap and good products, it is nothing but see through the essence.


Where to buy:

The first choice of course is Xiaomi's official website, which can be bought by sitting at home with little fingers. The disadvantage is that it costs 150 yuan for shipping, and you have to pay 10 yuan for shipping separately.

Followed by the millet flagship stores around, there is no worry about fakes, there is no postage concerns, as long as the goods want to buy how much. You can get it as soon as you pay.

The last place I recommend is: Jingdong

The purchase of diamond members can be sent directly to a single package, and it is handed out in the afternoon on the morning in the morning in the 211 area where goods are available. The province ran away. Encounter full product vouchers and white vouchers can also be reduced. With excellent after-sales service, than ... ... haha, say it became a trust. Used to know.


Unpacking:

Originally intended to post, the result ~ Jingdong spot became a reservation, scheduled to become a delay, until the 26th to give me delivery. Although a bit helpless, but a good 79 yuan package, but also demanded.

The front of the package. Finally there are color pictures.

The back of the package. Anyway, I'm not an expert. I don't care about posting.

How many times can I charge so much? There are too many factors that affect the “how many times”, temperature, discharge voltage, and discharge rate all have a direct impact on “how many times”.

If you really want to see it, then look here. The actual output is 6900mAh (5.1V), which is equivalent to 35.19Wh.

Jingdong self-purchase, true or false will not need to be tested. If it is false, I will be well developed.

Still the same, a short-term power supply is all.


main body:

The overall design still continues the 5000mAh version. From a distance, there is not much difference in appearance, but on the edge of the processing to the high version of the same, to get rid of the much-crippled 5000mAh edge cut fault.

The full text on the bottom nameplate, although not many people will really look seriously. Wait, September production? October 19 purchase but no goods? What happened to the month when this shipment was pressed in the warehouse?

Millet mobile power volume comparison with the mid-term change. In addition to thickness, length and width do not dominate.

22mm to 14mm.

60.64mm to 71.19mm.

91.2mm to 130.46mm.

Millet mobile power 121.6cm3 millet mobile power 2 130cm3. Actually, the volume of the previous generation was even smaller . This was rather unexpected.

208 grams to 221 grams. Millet Mobile Power 2 is also 13 grams heavier than the previous generation .

It seems that compared to what is worth buying a custom version of the millet mobile power, the 2nd generation does not have an advantage in terms of size and weight.


Dismantling:

The entire mobile power supply inner core fixing screw is two. There is no difference with the previous design.

Extracted core

The overall use of plastic frames, without the use of high metal thermal conductivity plate

Use a single 10000mAh force polymer battery. This is much more manageable than using 3 cells, and it is better than the generation from attenuation or internal resistance. In contrast, life expectancy is much higher than that of the 1st generation.

Motherboard front

Only a single cell, welding is relatively simple.

Motherboard back

The main control chip adopts a chip independently designed and produced by Purple Rice. The media evaluation version is ZMI PO2Q6RB, and my production version is PO2Q6RA.

The media evaluation version uses 6DA730, while the production version is 6DA725. And the production version is equipped with a fuse as the last line of defense.

Although Xiaomi heard a little about the difference between media evaluation and mass production, it was still very surprising to see it.

MicroUSB interface welding is very neat, the interface is different from the common form, the fixed ribs moved to the back, increase the plug life

The USB type-A interface is embedded in the motherboard to increase the insertion life. However, solder solder plumpness and media evaluation version are not in one grade.

Standard temperature detection.


performance:

Use QC2.0 charging connector produced by purple rice, the data line uses the original short line, the first time without shaking the QC protocol to open 9V charging is a little unexpected. However, this only happened once.

It is restored after reinsertion. There is no choice for 12V under QC2.0, but charging at 9V 1.9A.


It takes 3 hours and 30 minutes to fully fill. In fact, it takes almost 2 hours to use a fast charge, and the remaining one and a half hours is only filling the last 20%.

Discharge test. The initial voltage of 9V output stage of QC2.0 is 8.8V. Discharging at a rate of 2 A, the output voltage drops in just over half an hour. In other words, it can only be maintained for 30 minutes with full power output. This difference with the high version is still relatively large.

The lack of stamina after full output is like running a long distance runner. However, the output power of 15 W can be maintained for most of the time, and the power of 11 W can be output in the final stage. In this way, the performance is more general. The difference between the high and high version is highlighted. In other words, the limit of this mobile power is basically invisible at 5V 2A charging speed.

From this picture, it is easy to see that before many media evaluations chose to use 100% power, it was impossible to fully reflect the performance of this mobile power supply and fell into the circle of routine testing.


to sum up:

10000mAh can be said to be the most practical one of the mobile power segment, millet launched in this capacity segment of 79 yuan two-way fast charge mobile power is undoubtedly a price slaughter, to know before this 10000mAh two-way fast charge mobile power is in hundred dollars Above, Anker's QC two-way fast charge is often more than 150 yuan to buy. Although the late performance is not very satisfactory, it has to be said that there is no opponent at this price. It's not cheaper than it looks good, cheaper than its cheaper quality, cheaper than it's cheap and quality but it doesn't look good. However, this will only be a temporary phenomenon, but also expect other manufacturers to follow up.

advantage:

1, cheap, suitable for promotion.

2, feel better, two-color optional.

3, use the common MicroUSB charge, do not take the odd route.

4, two-way fast charge, better support for the QC protocol. Charging fast.

5, single batteries, long life, do not have to worry about long-term use of batteries after the internal resistance inconsistent problems.

6, support low-power charging, such as bracelet

insufficient:

1, the output power is weak.

2, Compared with the old models, the volume and weight have increased.

3, there is a reduction in the circuit.
