It is slightly thicker than the iPhone 8 Plus, but it is longer and wider than the iPhone 8 Plus, allowing users to have a very good hands-on experience.
Compared with the previous 18W USB PD mobile power supply of Quanhan, the shell material and process are the same, and the length of the product is slightly increased.
The advantage of having a 30W USB PD output is that it can not only support iPhone 8/8 Plus/X fast charging, but also allows New MacBook to charge at full speed, the effect is comparable to the original.
Second, Quanhan 10000mAh two-way 30W USB PD mobile power test
(1) Agreement testing
In accordance with past practice, first take a look at the USB-C port output capabilities of mobile power. Using ChargerLAB POWER-Z KT001 detection, the result is USB-C port supports USB PD2.0 fast charging standard, and has 5 voltage output The gears are 5V/2A, 9V/3A, 12V/2.5A, 15V/2A and 20V/1A, respectively, and the maximum output power is 30W. As a mobile power of 10000mAh level, the performance of this product is very powerful.
USB-C port not only supports 30W USB PD fast charge output, but also supports APPLE 2.4A charging protocol, which also allows iPhone 7, iPad and other devices that do not support PD fast charge to charge at full speed.
The compatibility of orange USB-A output interface (fast charge) is also very powerful. It supports APPLE 2.4A, Samsung 5V/2A, USB DCP, QC3.0/2.0, Samsung AFC, Huawei FCP and other protocols, covering almost all common High pressure fast charge agreement.
The white USB-A interface (conventional port) also joins the APPLE 2.4A charging protocol to further increase the usability of the product, which is also the gospel of Apple users.
(2) Maximum output test
Having said so much, how strong is the actual output ability of this mobile power of Quanhan? We have got the professional test equipment to test the maximum output capability of the USB PD protocol of this mobile power supply. The test equipments are respectively ChargerLAB POWER. -Z KM001C and An Shengda ASD916 integrated tester.
The maximum output voltage of USB-C port at 5V is 2.9A, and the maximum output power is about 14.7W.
The maximum output current of the USB-C port at 9V is 2.6A, and the maximum output power is about 23.4W.
The maximum output current of USB-C port at 15W voltage is 2A, and the maximum output power is about 30W.
The maximum output current of USB-C port at 20V is 1.7A, and the maximum output power is about 33.8W.
(3) Temperature rise test
In a 10000mAh class mobile power supply, the ability to support 30W USB PD bi-directional fast charge is currently very rare in the market, because the rise/fall process will generate a lot of heat.
We also made a limit test for the discharge temperature rise of the mobile power supply of Quanhan – the maximum current discharge is used at the highest voltage, and the temperature rise at this time is also the largest. The discharge equipment is Anshengda ASD916 comprehensive tester, temperature The test uses a FLIR thermal imaging thermometer with an ambient temperature of approximately 27°C.
In this test, set the discharge voltage to 20V and the current to 1.7A. Discharge the battery at maximum power (34W). Measure the temperature of the mobile power supply before and after the discharge. The following figure shows:
At room temperature 27°C, the maximum temperature of the surface of the moving power supply before discharge is about 34°C, the maximum temperature after discharge is about 15 minutes, and the maximum temperature is about 52°C, and the temperature rises by 18°C. The main heat source is concentrated on the PCB side. Some people may think this temperature rise is unacceptable, but Our test premise is overload discharge, which will not happen in daily use.
For Quanhan's 30W USB PD mobile power supply, the biggest role is to charge the laptop. After actual measurement, this product charge New MacBook voltage is 14.7V, current 1.8A, charging power is about 26.6W, with The effect of Apple's original charger is no different from that of the original 10000mAh mobile power supply that could be used to charge laptop computers. This should be the first. Similarly, we have also tested the temperature rise in this situation.
At room temperature 26 °C, 15V/1.7A continuous discharge for 15min, mobile power surface maximum temperature is only 38 °C, close to human body temperature, almost no heat on the touch, thanks to the use of high efficiency within the product The boosting scheme, on the other hand, uses a one-piece aluminum alloy cover to enhance the heat dissipation performance. In general, the temperature rise of this product in actual use is very good.
(4) Compatibility Testing
