Apple devices are among the best in the industry because of their exquisite workmanship and outstanding technology, but the lightweight design and lithium battery technology lag behind, making the following iphone In addition, we can't get rid of the fate of charging every day. For heavy iPhone users and people who go out, portable source It has become the standard configuration. But my own lightning The interface seems to have become an obstacle on many mobile power supplies, causing the fans to have to prepare an additional charging cable (or adapter). Where there is demand, there is a market. This is an eternal law in the business world, Feather Bo 10000mAh A1 The mobile power supply has dual inputs of Lightning and MicroUSB, which solves the embarrassment of fruit powder.
▍ Unpacking and details
Feather Bo There is the following slogan on its official website:“ Feather Bo People's vision of a better life is that life is colorful, happy, enthusiastic, tasteful and worthy of respect. People oriented, scientific and technological innovation, and integration into life to create outstanding and trustworthy products. Each breakthrough brings new surprises, little by little changes, and more people's lives Feather Bo It will become more wonderful, and our products and spirit will permeate all over the world... "This corporate vision is clearly reflected in Feather Bo 10000mAh A1 Mobile power supply. Feather Bo A1 The packaging of Yubo products is very simple, but the simple packaging still shows Yubo products' pursuit of color, happiness and enthusiasm. The three color design of meteorite ash, goddess purple and rose gold, and the slim body. Although the introduction of color into industrial design is a very "ancient" approach, Yubo's integration of product color design into life and enterprise spirit is still precious.
It slightly shows the back of the traditional packaging box, and all information is clear and clear. Lightning and MicroUSB dual input are still the focus of this mobile power supply.
The drawer type kraft paper inner box, this simple packaging design will make consumers pay more attention to the product itself.
The inner lining is also very simple. The all-in-one packaging box can also serve as the protection of fixation and buffering.
It seems that according to the industry practice, Yubo A1 It is equipped with a noodle type MicroUSB short cable and an instruction (warranty) book. However, for fruit fans, Yubo has Lightning input A1 , this MicroUSB short line seems to have become dispensable.
The Yubo A1 in my hand is officially named "Meteorite Grey", an extremely low-key and restrained tone; There is also only Yoobao's logo on the front, which is the essence of simple design and has been widely popular in the scientific and technological circles. The shell is made of aluminum alloy, sandblasted and anodized, and has a silky feel similar to that of iPhone.
Plain back.
Lightning, MicroUSB dual input, four level power display, standard USB-A single port output, CD buttons, all the highlights and functions are concentrated on this side. In addition to dual input, Yubo's pursuit of color is subtly reflected in the selection of USB-A seat. Yubo A1 uses an orange red rubber core USB mother seat, which is usually used in QC3.0 The quick charging socket appears on A1, but it doesn't need too many reasons. It is also possible to simply be beautiful.
The white light of the power display is projected through the small hole of the panel, which is very delicate. However, because there is no light guide column, the viewing angle is narrow.
The bottom of the other end has no ports or buttons except for relevant information labels.
Clearly and concisely marked, capacity 10000mAh (37Wh), input 5V/2A, output 5V/2.1A.
The shell edge is chamfered and smooth without cutting hands. Since the chamfering treatment is prior to the anodic oxidation process, the overall color of the shell is consistent, and there is no bright silver edge after CNC processing.
In terms of appearance design, Yubo A1 is not very innovative, even more "traditional", but its meticulous workmanship gives it a lot of points. Just like today's mobile phones, you will find that all mobile phones seem to be the same. In addition to the visual similarities, the only thing that can make consumers feel different is the product workmanship and attention to details.
In the accessories of Yubo A1, there is a MicroUSB noodle line with a silicone outer layer, which is very soft. In terms of line length, the length is about 30cm, and the short line design is convenient for A1 to connect with the charging equipment.
Both plugs at the end of the cable are made of iron, and the appearance and workmanship of the whole cable are flat, but because it is a short cable, it also performs well in actual use.
With the current lithium battery technology, thin and light still contradict the capacity. Yubo A1 adopts 10000mAh This is the "enough" standard. The capacity is twice as large as 5000mAh, and the volume is much thinner than 20000mAh. The three dimensions of Yubo A1 are 140 * 74 * 13.5mm. Friends who are not sensitive to numbers may not imagine how big Yubo A1 is. If the iPhone 6 is selected as a reference, Yubo A1 is only a little longer and wider than the iPhone 6.
In terms of thickness, Yubo A1 is only 13.5mm. Intuitively, if you use a dime as a contrast, A1 is smaller in diameter than the coin 10000mAh The thickness of mobile power supply is satisfactory.
In terms of weight, due to the use of aluminum shell, this design and material are naturally heavier than plastic materials. The actual measured Yubo A1 is 260g. This weight is approximately equal to the weight of two iPhones 6.
Thanks to the small and thin size and weight of Yubo A1, it will not bring you too much burden when you use it or carry it outside. You can hold it in your hand, put it in your bag, or even put it into the back pocket of your jeans, Anywhere you want.
▍ Measured
Yubo A1 has brought us a lot of joy in terms of appearance and lightness. We hope that some Yubo measured can also perform well.
1. Charging test
Test using jdb "Baize" charges Yubo A1. At this time, the remaining power of Yubo A1 is 3 lights, and the MicroUSB and Lightning cables (the cables are the MicroUSB cable and anker Lightning braid). The measured data of charging is:
MicroUSB cable charging, 5.2910V/1.9814A
Lightning cable charging, 5.2925V/2.0117A. From the measured data, the charging data of the two types of cables are similar, and the difference should come from the cable itself.
Discharge Yubo A1 to automatic protection shutdown, use JDB "Baize" to charge, EBD-USB+monitors the whole process, and the charging curve is as follows. The whole charging process takes about 5 hours and 50 minutes. In CC stage, with the increase of A1 power, the charging current gradually rises, up to 2.04A, and turns to CV mode in about 4 hours and 15 minutes. The curve is steep and the process is short; After the whole charging process, 51.72Wh energy is input, and the charging conversion efficiency is 37/51.72 * 100%=71.5%. Compared with similar products, the charging efficiency is not high, but it is also at the normal level in the 10000mAh level non fast charging mobile power queue.
2. Output test
EBD-USB+is used to test the output performance of Yubo A1. The test result is: the maximum output is 4.90V/2.30A/11.3W. There is no line compensation for the output. The voltage drops slightly with the increase of load current, and drops below 5.00V when the load reaches 1.70A. Although the voltage is slightly lower under high current, the maximum output of 2.30A has exceeded its nominal parameter value.
3. Output conversion rate test
The EBD-USB+constant current 2A mode was used to test the output conversion rate of Yubo A1. The result was that the total duration of 2A constant current discharge was about 3 hours and 16 minutes, the output energy was 32.60Wh, and the output conversion rate was 32.6/37 * 100%=88.1%. Although this efficiency is not excellent, it is also above the average level in the industry.
4. Output compatibility test
Compared with the above tests, output compatibility is a major concern of consumers, especially Apple device compatibility that Apple fans care about. The no-load status is tested with a green meter. The no-load voltage is 5.1270V, and the display supports Apple 2.4A and DCP 1.5A.
In the actual test, the iPhone 6 is charged (the remaining power is 28%, the screen is bright), and the charging data is 5.0456V/1.3060A, which supports Apple.
Charge iPad Air (remaining power 56%, bright screen status), charging data: 4.9326V/2.3097A, supporting Apple.
charge millet 4 (remaining power 78%, bright screen status), charging data: 5.0487V/1.2103A, basically reaching the full speed of Xiaomi 45 V.
Charge the Xiaomi 10400 mobile power supply (3 lamps of residual power). Charging data: 5.0336V/1.4350A. Since the Xiaomi mobile power supply is sensitive to voltage, A1 output voltage is slightly low and the charging current is small.
Charging Crowne mobile power supply (1 lamp of remaining power), charging data: 4.9799V/1.9496A, close to full speed.
During the charging and releasing test, when the MicroUSB port is used for input, the USB-A port has no output, which confirms that Yubo A1 does not have the function of charging and releasing at the same time.
From the above measured results, Yubo A1 is compatible with Apple and Android conventional DCP devices. Especially for Apple, it can achieve the same or even faster charging rate as the original charger.
▍ summary
From my personal experience, Yubo's 10000mAh A1 mobile power is very accurate, focusing on Apple users and taking into account the Android community. First of all, the colorful three color appearance is suitable for many people of all ages, genders and preferences; Secondly, the slightly "conservative" shape design coincides with the Chinese aesthetic concept of "moderation", and the grasp and control of details, volume and weight make this MMAH mobile power supply still have a slim figure. Lightning, Micro dual input design, 2A input, 2.1A (measured 2.3A) output, support Apple 2.4A, which seems to be completely customized for Apple users. You only need to bring the original iPad adapter and a Lightning cable to meet the charging and output requirements of all Apple handheld devices. Of course, some friends will say that Yubo A1 has a low input and does not carry mainstream fast charging technology. In fact, this is still a product positioning problem. If you have a full range of Apple devices, what's the use of QC or PE?
As a user of Apple devices, I can hardly find out the obvious shortcomings of Yubo A1. If you are looking for a mobile power supply suitable for Apple devices, I would like to say to you: "Yubo A1 is the most knowledgeable of fruit fans".
