Details
Product OverviewThis product is a high-performance DC power cord (DC connection cable), designed for powering various electronic devices. It adopts pure copper conductors and PVC insulation sheath, with good conductivity and durability, compatible with DC5521, DC2.5 and other interface specifications, meeting DC transmission needs in different scenarios. This cable is to connectpower adapterand load equipment, a key component ensuring stable power transmission.Product FeaturesHigh-quality copper core:The inner core uses high-purity oxygen-free copper, with low resistance and high conductivity efficiency, reducing energy loss. Compared with ordinary copper wire, oxygen-free copper has about 5% higher conductivity, effectively reducing heat andFAQ
What devices is this DC power cord compatible with?
It is designed to connect a power adapter to DC-powered load equipment, including surveillance cameras, LED light strips, and other devices. It supports common interfaces such as DC5521, DC2.5, and DC3.5, so check that your adapter and device use a matching DC connector.
Which DC connector size should I choose—DC5521, DC2.5, or DC3.5?
Choose the size that matches your power adapter output plug and your device input port. These common specifications are supported, so confirm the outer diameter and inner pin diameter before purchase to ensure a firm, stable connection.
Does the oxygen-free copper conductor make a real difference?
Yes. The high-purity oxygen-free copper core has low resistance and about 5% higher conductivity than ordinary copper wire, helping reduce energy loss and heat. This supports stable power transmission and can help extend equipment life.
How durable is the connector for frequent plugging and unplugging?
The connector is precision injection-molded for firm insertion and removal and good contact. It has passed over 5,000 insertion/withdrawal tests, helping prevent loosening or falling off during long-term use.
Can this cable be used in tight spaces or extreme temperatures?
The standard eco-friendly PVC sheath is flexible, tensile-resistant, and bend-resistant, making it suitable for wiring in narrow spaces. An optional silicone sheath is available with a temperature range of -40°C to 200°C for high- or low-temperature environments.
