9V Battery Clip Holder with 5.5mm/2.1mm DC Barrel Jack

The 9V Battery Clip with DC Barrel Jack is a staple accessory for any electronics prototyping workbench. Designed specifically for standard 9V block batteries (6F22/6LR61), this handy adapter bridges the gap between portable battery power and standard electronics power inputs. Instead of stripping bare wires and messing with screw terminals, this clip allows you to snap a 9V battery onto one end and plug the other end directly into your device's power jack in a matter of seconds.

Pre-wired with an industry-standard 5.5mm x 2.1mm center-positive DC plug, this cable is the absolute easiest way to make your Arduino Uno or Arduino Mega fully mobile. While a single 9V battery has a lower overall capacity than a 6x AA battery pack, this ultra-compact adapter takes up practically zero space, making it perfect for lightweight, space-constrained projects that only need to run for a few hours.

Key Features & Functional Advantages:

• Instant Plug-and-Play: Completely eliminates the need for soldering or breadboard wiring. Simply snap the battery into the clip and plug the barrel jack into your device.

• Pre-Wired DC Barrel Jack: Terminated with a standard 5.5mm (Outer Diameter) by 2.1mm (Inner Diameter) DC plug, configured as center-positive for immediate compatibility with modern development boards.

• Heavy-Duty Snap Terminals: Constructed with rigid, faux-leather or hard-plastic casing around tight-gripping metallic snap rings, ensuring the battery won't accidentally disconnect during movement.

• Flexible Wire Relief: Features approximately 10 to 15 centimeters of flexible, insulated wire, providing enough slack to easily mount the battery beside your circuit board without putting strain on the power port.

• Compact & Lightweight: Adds virtually zero weight or bulk to your project, allowing you to easily tape or velcro the 9V battery directly to the back of a small robotic chassis.

Perfect For:

• Arduino Prototyping: The quintessential accessory for powering an Arduino Uno, Mega, or Leonardo when demonstrating a project away from a computer's USB port.

• Classroom STEM Projects: An exceptionally safe and simple way for students to power up basic motor drivers and LED arrays without exposing bare positive and negative wires.

• Portable Test Equipment: Excellent for powering custom-built wire tracers, signal generators, and component testers out in the field.

• Low-Power Robotics: Ideal for supplying a dedicated, lightweight logic voltage to a microcontroller, while leaving heavy motor-driving duties to a separate LiPo battery.
