Introduction

ChargerLAB had done multiple tests on the MOVESPEED 140W PD3.1 charger. It can meet the charging needs of most devices. It also supports automatic power distribution and can charge four devices at the same time.

This time, we got its yellow version. To know how it can achieve a charging performance like that, we are going to take it apart to see its internal components and structure.

Product Appearance

The packaging box adopts a silver glossy design with MOVESPEED printed on the front.

The specs info are printed on the back. We'll talk about later.

The box contains the charger, a dual USB-C cable, and some documents.

The dual USB-C cable adopts a braided design, and the color is the same as the charger.

The connector has a double-layer design. The outer layer is made of transparent material, and the inner layer is made of green PC.

The braided design allows for a longer lifespan.

The length of it is about 121 cm (3'97'').

The ChargerLAB POWER-Z KM003C shows it can support 50V5A and has an E-marker chip. It can also support USB 2.0 and PD3.1 240W.

This charger comes in a bright yellow.
