In recent years, mobile phones support fast charging, mobile power supplies support fast charging, and mobile chargers support fast charging. Even laptops have begun to play fast charging. The problem is that supporting fast charging is nothing new, but the effect of fast charging depends on the actual charging voltage/current combination. The higher the charging power, the faster the charging speed.
However, many manufacturers may be suspected of false labeling due to publicity stunts. For example, a mobile phone (adapter) only supports 9V/2A (18W) fast charging, but it is not claimed that it can achieve 12V/2A (24W) fast charging. In addition, the actual charging speed of the same two mobile phones that claim to support 18W fast charging will also be different.
On the other hand, more and more notebook or tablet 2-in-1 devices are choosing USB PD Charging protocol (the mobile phone also supports this protocol), using Type-C interface for charging, while USB PD It supports a maximum charging power of 20V/5A, i.e. 100W. However, when it comes to actual products, your Type-C may only support 45W charging power, far from feeding USB PD 。 How to judge whether different devices use USB PD What about the instant power when charging?
When reading professional evaluation articles on the Internet, many children will see the USB tester (meter). Through it, they can detect how much W of charging power can be achieved with the original charger, which makes all kinds of false labels and exaggerated propaganda impossible. However, When we search and purchase on the Internet, we can only buy USB tester products that only support Qualcomm QC2.0 and MediaTek PE, and support for many new mobile phones and charging technologies is not ideal.
Today's experience product brought by Zhiqu Dog is a product named POWER-Z The specific model of the tester is FL001 , sold by the charging head network. The biggest feature of this tester is that it supports almost all charging schemes except OPPO VOOC, including Qualcomm QC, MediaTek PE, Huawei FCP, SCP, OnePlus DASH, and the fast charging protocols of Samsung and Apple.
Although the sparrow is small, it has all the internal organs
POWER-Z FL001 The size of the tester is similar to that of the early USB flash disk. It is composed of three layers, including the upper and lower glass fiber covers (for protection), and the middle is the circuit board.
The front is embedded with a 1.44-inch display screen, which will only turn on when powered on (for example, connected to the terminal block or mobile power supply). Next to the screen is a huge POWER-Z Logo。
POWER-Z FL001 There are more detailed parameter descriptions on the back of the USB PD The measuring range of the meter is 2V~24V/0A~5.5A, and it is said that the accuracy can be maintained at 0.0001V/A.
The front end is POWER-Z FL001 USB-A male connector for connecting charger, mobile power supply and other power supply equipment.
The rear part is a special USB-A female connector. In order to support USB PDs, it can pass 5A high current.
The top provides three interfaces: Micro USB, Type-C in and Type-C out. If you need to measure USB PD devices, you need to use the cables with Type-C interfaces on the bright side to connect Type-C In and Type-C Out respectively, and then connect them to the power supply and power access devices.
The POWER-Z can be switched through the microswitch at the bottom FL001 The status of the screen, switching between different test items.
Ultra simple test method
The POWER-Z FL001 is easy to use. The USB-A male connector is connected to the (mobile phone) charger, and the USB-A female connector is connected to the data cable. Then the display can monitor the real-time charging parameters.
The default display mode is rich in information. The dial displays voltage (yellow), current (blue), and power (purple) from top to bottom. The blue font on the left of the bottom box shows the internal temperature of the meter, the green font on the right shows the charging protocol, and the white font shows the voltage on USB D+and D -.
This is the charging test of Meizu E2. This mobile phone supports 9V/2A fast charging at most, and the measured charging power is between 13W and 14W.
This is the Le Pro 3 dual camera AI version. The measured charging power is about 22W, very close to its nominal maximum 24W charging power.
This is the 360 mobile phone N5. The nominal maximum is 18W, and the actual measurement is about 15W.
Xiaomi mobile power supply 2 supports QC and 18W fast charging, and the actual charging power for Le Pro 3 dual camera AI version is about 13W.
By the way, POWER-Z FL001 can also test the resistance of the data line. With the STM32 programmable single-chip microcomputer used inside the meter, users can also have their own DIY boot interface and various firmware. The upper and lower fiberglass panels can also be replaced at will.

If you want to play We Media and like to test the charging data of various digital products, this POWER-Z FL001 can be called a small artifact.
