Instead of providing power itself, it fits into the battery compartment of your device and passes external DC power from a wall adapter directly to your device via the DC 5.5mm cable. This lets you run battery-powered devices continuously without using or recharging batteries.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Which DC connector size do I need — 5.5x2.1mm or 5.5x2.5mm?\u003c\/h4\u003e\n\u003cp\u003eA: The difference is the inner pin diameter. Most common DC adapters use a 5.5x2.1mm connector, but some devices and adapters use the slightly larger 5.5x2.5mm inner pin. Check your DC power adapter's output connector specifications before ordering, and select the matching option to ensure a secure fit.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can this dummy battery spacer be used to charge a real 18650 battery?\u003c\/h4\u003e\n\u003cp\u003eA: No. This is a purely mechanical placeholder with a 0V non-conductive design. It has no charging circuitry and cannot charge any battery. It is designed exclusively to supply continuous external DC power to devices that normally use 18650 batteries.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What devices are compatible with this 18650 dummy battery eliminator?\u003c\/h4\u003e\n\u003cp\u003eA: Any device that uses a standard 18650-sized battery slot and can operate on the DC voltage supplied by your external adapter is compatible. Common examples include LED flashlights, handheld radios, DIY electronics projects, sensors, and portable lighting rigs.
