OYMSAE 25Feet SAE Extension Cable Quick Disconnect Connector 16AWG for Automotive, Solar Panel, Charging Adapter (25FT)

I bought this OYMSAE 25ft SAE Extension Cable to use with my Optima Batteries Digital 400+ 12V Battery Maintainer and Charger, and it works absolutely perfectly. The SAE connectors fit securely with the Optima charger leads, and the quick-disconnect design makes it super easy to hook up and unplug when needed. The 25-foot length is a game changer. I can keep my charger safely on the workbench while the vehicle stays parked where it is—no more juggling cords or dragging the charger around the garage. The cable itself feels sturdy and well-insulated, with solid strain relief at the ends. Definitely doesn’t feel cheap. I’ve been using it to maintain AGM and automotive batteries and haven’t had any issues with voltage drop or connection problems. If you have the Optima Digital 400+ and need extra reach, this extension pairs with it extremely well. Highly recommended 👍

EXACTLY what I needed and works great. Also comes with a necessary polarity converter, which is needed before plugging into the solar port. Prompt delivery and packaged very well. Thank you OYMSEA!

Perfect charging system multiple connections and a cord with durability. It's also has multiple lengths.

They work for my solar set up, but I end up later making a higher gauge wire cable for it. This cable only got me a few watts lower than my higher guage wire cable. That's fine but when every watt counts it matters. Good on a budget, but spend more on a higher gauge cable

Well made with tight connections

Perfect extension, just what I was looking for.

Great battery charger charging wire extension.

Fast delivery, works well, having the polarity reversal piece saves any worries for proper hooking up.

does the job

Exactly what I needed..

this will be nice to be able to have a solar panel movable to get it in the sun

Funciona a la perfección. Necesitaba un cable largo para conectar mi panel Dokio al interior de la casa y alimentar un Fremo X700 y estoy muy contento con el desempeño del cable. El adaptador de polaridad solo es necesario usarlo si por alguna razon el empalme de los cables cambia la polaridad. Yo no lo necesité. Lo recomiendo ampliamente!

This extension set worked as expected and hoped for to help get my Dokio portable Solar kit a little further away from our 5th wheel camper. It has a connector that comes with it that will change the polarity if needed depending on your connection which I did not end up needing. I am happy with this product so far.
