The waterproof cover is a little too easy to open and close, but not an issue so far. ### ⭐⭐⭐⭐⭐ Great *by S***2 on November 15, 2025* Works as it should. I replaced the 12v socket I didn’t use on my street glide with this. Works great for winter storage plus there’s a bunch of adapters you can buy that plug into this. Nice solid connection using my Noco battery tender, install was easy. For the price was well worth it. ### ⭐⭐⭐⭐⭐ Perfect Addition to My Travel Trailer *by D***E on April 13, 2018* I have been in the process of upgrading my electrical setup on my travel trailer, which meant a new battery box. One of the additions I made was an integrated cutoff switch in the box. That came out so well I decided to also integrate a charging port so I would never have to open up the box for routine maintenance. This connector filled the bill perfectly. I drilled a hole in the end of the box and slipped it right in. The packaging says to drill a 23/32" hole but don't worry, an 11/16" hole with a Unibit fit perfectly. I didn't need the plug end on the wire so I cut it off and crimped 5/16" ring terminals on the wires to go to my threaded battery posts. Be sure and install the rubber grommet on the outside of the box if this is exposed to weather like mine. Now I can plug in my Battery Tender whenever I need to, with no hassle. I think I'm going to use the plug I cut off and wire it to some alligator-clip test leads, then I'll also have an easy way to check battery voltage if necessary. ## Frequently Bought Together - Tecmate OptiMATE Cable O-40, Weatherproof SAE socket, panel mount, Black - Battery Tender Ring Terminal Harness Accessory Cable - 18 inch Cord Adapter with SAE Quick Disconnect - Easy Quick Convenient for Motorcycles, Cars, ATVs and More - 081-0069-6 - Battery Tender Junior 12V, 750mA Charger and Maintainer: Automatic 12V Powersports for Motorcycle, ATVs, and More - Smarter Than a Trickle Charger - 021-0123 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/42045004-tecmate-optimate-cable-o-40-weatherproof-sae-socket-panel-mount](https://www.desertcart.at/products/42045004-tecmate-optimate-cable-o-40-weatherproof-sae-socket-panel-mount) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-04-28*
