Protocol testing
In addition to supporting PD protocol, the Type-C interface is tested from the perspective of comprehensive exploration, so that users can match output devices according to specific protocols.
Use the POWER-Z KM003C tester to read the fast charging protocol of the port, and the Type-C port of the charging chamber that supports the iWALK Pocket Power Bank Plus actually supports PD3.0, QC4, DCP, PPS and other charging protocols.
In terms of PDO messages, Type-C port has three sets of fixed voltage gears: 5V/2.4A, 9V/2.22A, 12V1.67A, and one set of PPS voltage gears: 3.3-11V/2A.
The POWER-Z KM003C tester was used to read the fast charging protocol of the port, and the USB-A port of the charging bin that supports the iWALK Pocket Power Bank Plus was measured to support charging protocols such as FCP, SCP, AFC, QC3+, SFPP, DCP, and Apple2.4A.
Product evaluation
Next, let's take a look at the specific use experience of this power bank.The charging head network will lead you to understand this product from the aspects of compatibility test, input whole process test, output efficiency test, etc.
Charging compatibility test
The iWALK Pocket Power Bank Plus Direct Plug Module comes with a Lightning Direct Plug, and the charging compartment module also has a Type-C port and a USB-A port. Let's see how fast charging compatibility works.
Connect the Redmi K70 Pro mobile phone to the Type-C port of the iWALK Pocket Power Bank Plus, and use the POWER-Z KM003C tester to read that the input power of the mobile phone terminal is 7.72V 1.57A 12.08W.
Summarize the data to the table. Most mobile phones can shake hands on the 9V voltage gear, and most other tablets and laptops can shake hands on the 12V voltage gear. The maximum charging power can reach 19.16W.
The histogram is drawn. It can be seen that the charging power of devices compatible with PD fast charging is more friendly, and most of the charging power is maintained in the range of 15~20W;For other devices with poor compatibility with PD, the charging power is about 12W.
Connect the iPhone 15 Pro phone to the USB-A port of the iWALK Pocket Power Bank Plus, and use the POWER-Z KM003C tester to read that the input power of the phone terminal is 4.89V 2.93A 14.39W.
Summarize the data to the table. For most mobile devices, the 5V or 9V voltage can be used, and the maximum charging power can reach 17.43W.
The histogram is drawn. The USB-A port of iWALK Pocket Power Bank Plus is compatible with many mainstream charging protocols, and its charging power is friendly. Most charging power is maintained in the range of 10~18W.
Multi port simultaneous output test
The charging compartment of the iWALK Pocket Power Bank Plus is equipped with two 1C1A USB ports. The specific power distribution when two ports output at the same time needs to be tested.
Charge the mobile phone and laptop through the two USB ports of the iWALK Pocket Power Bank Plus, and the measured input power of the device terminal is 9.28W and 6.27W respectively;At the same time, the Lightning plug of the inline module can also directly charge the iPhone, that is, it can recharge the power of three devices at the same time.
Full charge test
The charging chamber of this iWALK Pocket Charger Plus is tested in the whole process. The Apple 140W charger is used to charge it. The test is carried out in a 25 ℃ thermostat. The charging process is as follows.
Connect the power supply and shake hands with 12V voltage. The power is stable at 18W and the charge lasts for 1 hour and 30 minutes;Then the power decreases continuously until it is fully charged. The whole charging process takes about 2 hours and 29 minutes.
The broken line diagram is drawn. It can be seen that using Apple 140W charger to charge the charging bin of iWALK Pocket Power Bank Plus takes 59 minutes to charge to 50%, 1 hour and 34 minutes to charge to 80%, and 2 hours and 29 minutes to charge to 100%.
Output efficiency
The output efficiency is an important factor to measure the quality of the power bank. The power bank's efficiency is different when it outputs in different gears. The higher the output efficiency, the higher the conversion rate, the lower the heat. This time, we also tested the output efficiency of the power bank's charging chamber at different gears.
First, let the charging chamber of the power bank continuously output at 5V3A 15W, and finally end at 1 hour and 51 minutes;The actually released battery energy is about 27.33Wh, so the efficiency of the power bank when outputting at 5V3A 15W is about 27.33/32.4=84.35%.
Then let the power bank continuously output at 9V2.22A 20W, and finally end at 1 hour and 20 minutes;The actual discharged battery power is about 26.08Wh, so when the power output of the charging bank is 9V2.22A 20W, the efficiency is about 26.08/32.4=80.49%.
Then let the power bank continuously output at 12V1.67A 20W, and finally end at 1 hour and 20 minutes;The actual discharged battery power is about 26.20Wh, so when the power output of the power bank is 12V1.67A 20W, the efficiency of the power bank is about 26.20/32.4=80.86%.
Summary
The charging chamber of iWALK Pocket Power Bank Plus was continuously output tested from 15-20W different gears, and the output conversion efficiency was between 80.49% and 84.35%. The efficiency reached 84.35% under 15W power output, and reached 1 hour and 51 minutes under 15W power output. The overall performance was excellent.
Summary of charging head network
The iWALK Pocket Power Bank Plus adopts a black skin like material shell on the appearance, which makes the whole machine feel warm and moist, without leaving fingerprints. At the same time, it adopts a combined design of charging bin+in-line module, with a total capacity of 13500mAh;In addition to the portable charging of iPhone, other mobile phones and laptops can also be charged through the charging bin module. At the same time, the LED power digital display screen can also easily grasp the power status.
In terms of charging, the direct plug-in module has a USB-C/Lightning plug model to choose from, which can be used as a capsule charging bank alone. The Lightning model supports 12W output, and 4500mAh capacity is convenient for recharging mobile phones at any time;The charging chamber is a gold combination of 9000mAh+1C1A dual interfaces. Port A supports up to 18W output, while port C supports 18W input and 20W output. It is compatible with the common fast charging protocol in the market. Common models can provide high charging power. The entire iWALK Pocket Charger Plus can charge three devices at the same time.
In terms of input, Apple 140W charger is used to charge the charging bin of iWALK Pocket Power Bank Plus. It takes 59 minutes to charge to 50%, and 2 hours and 29 minutes to charge to 100%, which is consistent with the official promotion.In terms of output efficiency, the iWALK Pocket Power Bank Plus charging chamber has conducted continuous output tests at different gears of 15W and 20W respectively. The output conversion efficiency is between 80.49% and 84.35%, and the 15W power output lasts for 1 hour and 51 minutes, showing excellent performance.
On the whole, as the world's first direct plug-in power supply with its own charging compartment, the iWALK Pocket Power Bank Plus provides a more convenient charging mode;The charging chamber further guarantees the endurance, and the two additional 1A1C interfaces can quickly charge common devices on the market, making use of them more flexible.
