At present, most of the electronic products in the hands of users almost include laptops, which are also productivity tools for many users. In my opinion, every time I need to travel on a business trip by means of transportation, I need to carry my notebook for emergencies, and the probability of using it on the road is very high.
Although the battery life of some laptops is good now, for heavy users like Xiaobian, it is not reassuring to go out without carrying a high-power power charger. There are three points to choose from the power bank: first, the power and capacity should be large enough, and second, the power bank should be able to get on the plane normally. At present, the new model of TECLAST 60W The two-way fast charging power bank can fully meet the demand, and it is also very small.
1、 TECLAST 60W Introduction to two-way fast charging power bank

USB-C supports 20V 3A 60W fast charging regardless of input or output. In addition to allowing itself to quickly restore power, it can also provide enough endurance support for the notebook, which is good.
The TECLAST 60W two-way fast charging power pack is equipped with three 1C2A USB output interfaces. The USB-C in the middle supports two-way fast charging. The USB-A1 on the left is a green rubber core, and the USB-A2 on the right is an orange rubber core.
The power button is located on the side, which is integrated with the lines on the side, so the sense of integration is strong and not abrupt.
There are 4 power indicators on the side, each of which represents 25% of the remaining power. At this time, the power bank is in full charge state.
One of the indicators is given the indication of fast charging. When charging the iPhone 12 Pro with the USB-C interface, the voltage is raised to the 9V fast charging output state. At this time, the leftmost indicator changes from white to green, meaning that the power bank has entered the fast charging state.
The advantage of this is that the user can judge by the color of the indicator light Whether the equipment enters fast charging After all, except for enthusiasts and professionals, not every user has the POWER-Z tester.
3. Volume weight
The measured length of the power pack with a caliper is about 108.57mm.
The width is about 69.51mm.
The thickness is about 26.88mm.
The net weight of the entire power pack is about 275.9g.
Compared with the iPhone 12 Pro Max, the size is very intuitive.
The entire power pack can be held in one hand, but it still has a sense of existence.
2、 Protocol detection
1、USB-C
Use ChargerLAB's POWER-Z KT002 to read the fast charging protocol of the USB-C interface. USB-C supports fast charging protocols such as PD, PPS, Apple2.4A, QC2.0, QC3.0, and QC4+.
When the power bank output triggers PD fast charging, it will provide five full fixed voltage gear outputs, namely 5V2.4A, 9V3A, 12V3A, 15V3A, and 20V3A. In addition, USB-C also supports 3.3-11V 3A as a group of PPS fast charging.
2、USB-A1
Read the fast charging protocol of the USB-A1 interface, and the actual measurement supports Apple 2.4A, SCP and other fast charging protocols.
3、USB-A2
Finally, read the fast charging protocol of the USB-A2 interface, and the actual measurement supports Apple 2.4A, QC2.0, QC3.0 and other fast charging protocols.
The above is to test the fast charging protocol and PD output gear of the charging bank interface using ChargerLAB POWER-Z KT002. Next, we will further verify the fast charging support through the compatibility test to avoid errors.
3、 Charging compatibility test
1. USB-C output
USB-C supports PD fast charge output, and can provide 9V fast charge when charging iPhone 12, with a power of about 23W.
The iPad Pro also supports the USB PD fast charging protocol. It uses USB-C to charge the iPad Pro, and the measured power is 15.15V 2.17A 33W.
The MacBook Pro 16 can provide 58W+fast charging power, which has reached the maximum output power of the power bank.
The 60W fast charging output power is also fully satisfied for the latest MacBook Air M1 launched by Apple. The power bank can provide 46W+fast charging power for the MacBook Air M1.
If you want to successfully activate the base TV mode of the switch, the charging device must support the output gear of 15V3A or higher. It is measured that USB-C power supply is used, and it can be successfully turned on The base TV mode of the switch.
From many test data, 9V PD fast charging gear can be basically provided for mobile phones, and 15V or 20V high-voltage output gear can be provided for switch, iPad, laptop and other high-power electrical equipment, so as to better meet the power demand of equipment.
In the whole histogram, the power of the laptop is naturally the highest. Some mobile phones that support PPS fast charging have higher power, ranging from 23W to 25W. The charging power of the iPhone is stable at about 18W - 23W. Some models behind the bar graph have low power. This is because the mobile phone limits the power of PD fast charging, which results in low power output of the power bank. However, most of them are still in fast charging state.
2. USB-A1 output
USB-A1 supports general QC fast charge. USB-A1 is used to charge Xiaomi 11, and the measured power is 9.13V 1.86A 17.07W. QC fast charge is successfully triggered.
For iPhone twelve The mobile phone can also provide Apple 2.4A charging, with a power of about 12W.
USB-A1 provides SCP fast charging for Huawei mobile phones, Apple devices use conventional Apple 2.4A charging, and most other Android phones can provide QC fast charging, with good overall compatibility.
From the whole histogram, Huawei mobile phones naturally have the highest charging power, followed by other Android phones, and Apple devices are stable at about 12W.
3. USB-A2 output
Use USB-A2 to charge the Red Devil 6 Pro with a power of 9.02V 1.71A 15.48W, which can also trigger QC fast charging.
USB-A2 provides QC and FCP fast charging for most Android phones. For Apple devices, the conventional Apple 2.4A charging is used, and the power is about 12W.
The trend of the whole histogram is also relatively gentle. The power of Apple devices is about 12W, and the charging power of Android phones is about 9W - 20W.
4. Multi port simultaneous output
(1)USB-C+USB-A1
At the same time, USB-C and USB-A1 are used to charge the two mobile phones, with the power of 9.66W and 10.29W respectively. The power bank supports simultaneous output of USB-C and USB-A1 and shares 5V3A output.
(2)USB-C+USB-A2
Replace USB-A1 with USB-A2, and the actual measurement also supports dual port simultaneous output and sharing 5V3A output.
(3)USB-A1+USB-A2
At the same time, two USB-A interfaces are used to charge two mobile phones, with the power of 9.62W and 7.73W respectively. The power bank supports two USB-A interfaces to output simultaneously and share 5V3A charging.
(4) Three ports output at the same time
Finally, three USB interfaces are used to charge three mobile phones at the same time, with power of 6.72W, 10.78W and 10.28W respectively. The power bank supports simultaneous output of three USB interfaces, with a total output power of about 27W.
5. Filling while placing
Use USB-C to self charge the power bank, and use USB-A to charge the mobile phone at the same time. The actual power bank does not support charging while discharging.
6. Self charging input
TECLAST's newly launched power bank supports 60W fast charge output and 60W fast charge input in addition to 60W fast charge output. With a 60W or higher power charger, you can get a better experience of self charging speed. It is measured that the charging power of 100W charger for the power bank is 59W+, which not only needs fast charge output, but also needs fast blood return.
Use Apple 96W charger to charge the power bank. The power was about 62W 15 minutes ago. The power was about 47W before 47 minutes, and then the power and current gradually decreased until the end of charging. The whole process took about 2 hours and 06 minutes, and the maximum power was 20.30V 3.06A 62.19W.
4、 Output efficiency test
1、5V2A
The output efficiency refers to the ratio between the actual energy and the nominal energy of the power pack when it outputs at different power levels. The calculated percentage is the output efficiency of the power pack in different output gears. The higher the efficiency, the more energy the power pack emits.
First, test the output efficiency of the power bank with 5V2A gear. The voltage, current and power platform are very stable throughout the test. The whole journey takes about 4 hours and 14 minutes. The energy released is about 44.4446 Wh, so the efficiency of the power bank when outputting at 5V2A gear is about 44.4446/50=88.89% 。
2、9V2A
Raise the voltage to 9V, and test the output efficiency of the power bank at 9V2A. The whole test process is the same as 5V2A. The whole process takes about 2 hours and 28 minutes. The energy released is about 45.0248 Wh, so the efficiency of the power bank when outputting at the gear 9V2A is about 45.0248/50=90.04% 。
3、20V3A
Finally, the output efficiency of the power bank was tested at the 20V3A gear. It was found that the voltage and current dropped to 5V3A output when the test lasted for about 10 minutes, and finally lasted until 2 hours and 17 minutes.
5、 Carry on the plane
As for whether TECLAST's 60W rechargeable bank can get on the plane, the relevant regulations of the Civil Aviation Administration have specified that those whose rated energy does not exceed 100Wh (cell capacity is about 27000mAh) can get on the plane directly, and those whose rated energy is between 100Wh and 160Wh (cell capacity is about 27000mAh~43000mAh) can get on the plane legally after being approved by the airline.
The battery energy of the TECLAST 60W two-way fast charging power pack is 50Wh, which is far lower than the regulations of the Civil Aviation Administration on the battery energy of portable power supply, and it can be directly carried on the aircraft.
Summary of charging head network
Since iPad, laptop and other devices replaced the charging interface with USB-C and supported USB PD fast charging, the development of high-power fast charging power packs has been promoted. The overall design of this TECLAST power pack is flat and square, and the smooth transition at the edge is easy to handle.
The power bank is equipped with three USB charging interfaces of 1C2A. In terms of performance, it supports fast charging protocols such as PD, Apple2.4A, QC2.0, QC3.0, QC4+, and SCP. When the PD fast charging output is triggered, it supports five full fixed voltage gear outputs of 5V2.4A, 9V3A, 12V3A, 15V3A, and 20V3A. In addition, USB-C also supports a group of 3.3-11V 3A PPS fast charging. In the actual compatibility test, fast charging service can be provided for most devices, and because it supports 15V3A output, the switch's pedestal TV mode can also be successfully activated, which performs well.
The USB-C interface of the Power Bank supports 60W two-way fast charging. Choosing a high-power PD charger of 60W or above can achieve the ultimate fast charging experience. The 15000mAh battery of the power bank can be fully charged in just 2 hours with a high-power charger.
