Frequently Asked Questions
Q: What laptops is the USB-C PD to 3.5×1.35mm 12V adapter compatible with?
A: This adapter is designed for laptops that use a 3.5mm × 1.35mm DC barrel power port rated at 12V — most commonly Jumper EZbook 2, 3, 3S, 3 Pro, and 6 Pro, as well as Medion Akoya series laptops. Always verify your laptop's input voltage (12V) and DC plug size (3.5×1.35mm) before use.
Q: Can I use any USB-C charger with this adapter?
A: You need a USB-C Power Delivery (PD) charger or power bank that specifically supports 12V output on its USB-C port. Standard 5V USB-C chargers will not supply the correct voltage. Check your USB-C PD charger's specifications to confirm 12V PD support.
Q: Is this adapter plug-and-play or does it require setup?
A: This is a fully plug-and-play connector — no software, drivers, or configuration needed. Simply plug your USB-C PD source into the USB-C end and connect the 3.5×1.35mm output to your laptop's charging port.
Q: What is the difference between a 3.5×1.35mm and other barrel connector sizes?
A: Barrel connectors come in various diameter combinations (e.g. 5.5×2.1mm, 5.5×2.5mm, 4.0×1.7mm). The 3.5×1.35mm refers to the outer diameter of 3.5mm and inner pin diameter of 1.35mm. Using the wrong size can result in a loose or non-functional connection, so it is important to confirm your laptop's exact port dimensions.
