It can charge the mobile phone at the same time with the use of competitive mobile phone. It is flexible and convenient to use. Each usb-c port supports a maximum output of 90W. When dual ports output at the same time, each port is reduced to 45W, and it only takes 30 minutes to fill 5000mAh battery. Next, the charging head network will disassemble this charger, let's take a look at its internal design.

At present, the charging head network has disassembled Lenovo 65W PD fast charging Matchbox power supply, ThinkPlus 65W Gan, 65W power adapter adlx65ycc2a, 65W power adapter ls-65wtcqcpd, Lenovo 65W USB PD fast charging charger adlx65ycc3a, Lenovo 65W usb-a fast charging charger ls-65wtaqcpd, Lenovo Yoga 65W PD charger and ThinkPlus 45W lipstick power supply ThinkPlus 65W lipstick power supply and other products, you can also click the blue font to view more disassembly reports.

1、 Appearance of Lenovo 90W dual usb-c Gan charger

Lenovo's 90W dual usb-c Gan charger is packaged in pure black and white with cyan font, which looks more chic. Lenovo dp90 dual power adapter and Gan are printed on the front. The label on the back of the box records the manufacturer's information.

The charger body is wrapped with paper lining, which has the effect of shock absorption. The overall packaging box is small, light and easy to transport.

There are no other accessories except the charger and instruction manual.

This charger is made of PC flame retardant material with black shell and matt surface. The body adopts geometric ID style design, with square shape and sharp edges, which makes the charger full of scientific and technological sense.

The Lenovo brand logo is set in the lower left corner of the fuselage.

From the direction of the input end, the four ends of the side body are vertical and chamfered respectively, with symmetrical design. The input shell is marked with charger parameter information:

Model: lc-908 sa18c88607

Input: 100-240V ~ 50 / 60Hz 1.5A

Single port output: 5v5a, 9v5a, 15v5a, 20v4.5a

Dual port output: 5v3a, 9v3a, 15v2.5a, 20v2.25a

Manufacturer: Jiangsu Chenyang Electronics Co., Ltd

The product has passed 3C certification and VI level energy efficiency certification.

In addition, it is equipped with foldable GB pin, which is easy to carry.

The edge of the output end is chamfered. There are two usb-c interfaces in the center of the output top surface, and the black rubber core does not expose copper.

The measured length of charger body is about 66mm by vernier caliper. The width is about 63mm. The thickness is about 28mm. Compared with apple 61W charger, Lenovo charger is smaller. The intuitive feeling of holding it in the hand. Summary of dismantling charging head net

Lenovo savior E-sports mobile phone Pro is equipped with two usb-c interfaces and this 90W super flash charger for dual port charging at the same time. It can be fully charged with 5000mAh battery in 30 minutes. Not only the design concept is advanced, but the actual effect is also very good. The two usb-c ports of the charger support QC, PD and PPS fast charging protocols, which have the same performance and are flexible and convenient to use. In addition to the rescuer's mobile phone, it can also be used to charge the notebook. Two devices can be charged at the same time, and one is enough.

The charger is equipped with foldable pins, which is convenient for users to carry. The body shape is square and the edges are clear. The overall style is full of science and technology. Through the disassembly of the charging head network, it is found that the whole PCB module is wrapped with a brass radiator, the components on the circuit board are welded in a compact and orderly manner, the circuit is clear, and the input and output terminals are equipped with a small board, which makes full use of the internal space to reduce the volume.
