MILAPEAK (Real 18AWG) 10 Pairs 12V 5A DC Power Pigtail Barrel Plug Connector Cable, 2.1mm x 5.5mm Male Female DC Pigtail Connectors for CCTV Security Camera and 12V Power Supply Adapter

used these leads to make a quick connect to a battery source. These hold tight and make a great connection. Wire diameter is fine for several amps, nothing more than 5 amps. Solder well too.

The amazon ad doesn’t do these justice. I purchased these because they were cheap but most importantly I would have them next morning. Fully expecting cheaply made sub par quality but was extremely surprised these are heavy duty quality which was a pleasant surprise. If you’re expecting a radio shack flimsy wiring this isn’t it. Happy with this purchase and will be buying again.

I returned this product

Just what I needed.

Nice heavy pigtail leads for my high-current application. Firm, solid interconnections with every mating barrel connector Ive tried. Arrived in under 24 hours -- amazing. Color me very happy with this product.

Good well built actually 18g as listed

Just measure continuity before soldering. The very first female connector I used was bad, which I only realized after got it attached to a DC motor I was going to use.

Very nice quality products - highly recommended!

Not the right size for motorcycle heated clothing. Wire gauge too small, and the internal pin is too small. Wont carry enough amperage. This pin is 2.1mm, but you need a 2.5mm pin to be compatible with OEM suppliers connectors.

These are a standard that make it easy to splice power to many electronics. From 12 volt car accessories, to laptops, I make extension cords from these to comfortably use devices where I want to use them. This is a great value, and you cannot beat their prices or delivery. A definite 5 star. This is also a repeat order.!!
