Compact Inline Design: Its streamlined profile makes it an ideal addition to technical repair kits, mobile workstations, or space-constrained electronic setups.
Male Connector (Output): 5.5mm (OD) x 2.1mm (ID) DC Plug.
Female Connector (Input): 4.0mm (OD) x 1.7mm (ID) DC Socket.
Color-Code: Yellow Identification Ring on the 1.7mm Interface.
Housing Material: Reinforced Impact-Resistant ABS.
Application: Ideal for adapting specialized laptop chargers, small household appliances, and proprietary electronic modules to standard DC equipment.
How do I know if the 1.7mm socket matches my charger? The 1.7mm inner diameter is a common size for smaller electronics and is almost always visually identified by a yellow tip or a yellow internal ring. If your charger plug has a yellow tip and a 4.0mm outer diameter, this adapter is the correct choice.
Does this adapter change the voltage of my power supply? No, this is a passive adapter. It only adapts the physical dimensions of the connector. You must verify that the voltage and amperage of the power source being plugged into the socket match the requirements of the device you are powering.
Is the connection secure for industrial use? Yes, the precision-machined barrel and internal spring-loaded contacts in the 1.7mm socket are designed to maintain a firm mechanical lock, minimizing the risk of power interruptions due to vibration or accidental tugging.
