Frequently Asked Questions

Q1: How to select the appropriate DC single-end male/female cable specifications?
 A1: First confirm the DC interface size of the equipment (e.g., 5.5*2.1 mm), then calculate the current based on the equipment power (Power ÷ Voltage). Reserve a 20% margin when selecting the wire gauge (e.g., 0.75 mm² for 12V/40W equipment, 1 mm² for 12V/70W equipment). Use PVC cables for indoor applications, PUR cables for outdoor/industrial applications, and thicker wire gauges for long-distance wiring.
 
Q2: What is the maximum customizable length? Will long-distance wiring affect power supply?
 A2: The maximum customizable length is 20 meters. Slight voltage drop may occur in long-distance wiring, which needs to be evaluated according to the wire gauge and power: for 12V systems within 10 meters and power ≤ 50W, the voltage drop is negligible when using 1 mm² cable. For distances over 10 meters or higher-power power supply, 1.5 mm² wire or shorter cables are recommended.
 
Q3: Can single-end male/female cables be connected in series to extend the transmission distance?
 A3: Series connection is not recommended. It increases contact points, leading to poor contact, doubled voltage drop, and higher risks of overheating and failure. For long-distance power supply, directly customize a single cable of the required length or use thicker wires to ensure stable power supply.
 
Q4: What is the product warranty policy?
 A4: The warranty period is 1 year (for non-artificial damage). The warranty covers quality issues such as poor connector contact, sheath rupture, wire oxidation and overheating, and insulation failure. Damage caused by human factors (e.g., excessive pulling, puncturing, overload, incorrect high-voltage connection, unauthorized disassembly, etc.) is not covered. Free replacement and repair services are provided within the warranty period, with a 24-hour response
