Igreeman 10 Pair Male & Female DC Power Pigtail 18 AWG 5A Upgraded with Terminal Jack 2.1mm 5.5mm Connectors for Home Security Surveillance Camera and Party lighting

This is the most common size of barrel jack I encounter. I like to test things that come with a wall wart running on car battery, vehicle alternator power, 24v wheelchair power, or DC-DC converters. I only needed one when I ordered this, but have since found a use for every single one.18AWG wire is a little thin for some projects so next time I'll look for some a little thicker, and with larger screws.

These plugs work well! My only complaint was the smell. They have a strong order and months later it's better but still there. Overall it's not a bad deal.

These pigtails are of excellent quality. They are great for connecting raw wires. Bare wire ends slipped in easily with no wire strands bending back. Wires appear to be much more secure than using the old twist caps.

The wires worked perfect and are of good quality.

Connectors are well made and durable screw connections make easy work of connecting to cables
