About this product
Overview
These CHANZON UL Wire connectors let you power Arduino boards or LED strips directly from a 9V battery, solving the need for portable power without a bulky wall adapter.
Key Specifications
Each adapter uses a 2.1mm x 5.5mm male DC plug with center positive polarity, and the five-pack includes UL-certified wiring for reliable current delivery up to 1A from any standard 9V battery clip.
Who It's For
Hobbyists prototyping with Arduino or ESP32 can power their projects on a breadboard without hunting for a USB cable. It’s also perfect for testing LED strip lighting or small motors away from a wall outlet, especially when you need multiple units for different setups.
Worth Buying?
These cheap connectors turn any 9V battery into a handy lab supply, and the 5-pack covers lost or broken adapters. For the price, the build quality is solid enough for light-duty electronics work.
