A cordless spray gun features a rechargeable battery, a paint container, an adjustable spray nozzle, and variable flow control to provide smooth, consistent coverage. Its lightweight, ergonomic design allows users to move freely and work in areas without access to electrical outlets. Most models offer multiple spray patterns (horizontal, vertical, and circular) and adjustable paint flow, making them suitable for a variety of painting tasks. The spray gun is easy to assemble, clean, and maintain, helping users save time while achieving a professional-looking finish with minimal overspray.
