Rated for 30 amps, wired in tinned 12 AWG copper, and fused on both legs. Color-coded connectors slide together and snap shut, no cutting or splicing.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you've ever mounted an on-board battery charger only to find the factory leads come up a foot short of the bank, the Guest 27505 is the fix. It's a 5-foot DC cable extender that bridges the gap between your charger and the battery without any cutting, stripping, or splicing. Slide the color-coded leads together, snap the insulated covers shut, and you're done.\u003c\/p\u003e\n\u003cp\u003eThis is built for the marine environment, not a generic auto part pressed into service. The conductor is tinned 12 AWG copper, so salt air and the damp that lives in every bilge won't turn the strands green inside the jacket. The hardware is gold-plated to keep resistance low at the connection, which matters when you're pushing charge current across a plug interface season after season.\u003c\/p\u003e\n\u003cp\u003eIt's rated for 30 amps, which covers the output of typical on-board marine chargers that use ring terminal cables. And it ships with dual inline waterproof fuses already built in, so the extended run is protected without you having to add a separate fuse holder. That's one less part to source and wire when you're trying to get the boat buttoned up before the weekend.\u003c\/p\u003e\n\u003cp\u003eInstallation is genuinely tool-free. The leads are color-coded, so there's no guessing which side is positive. You line up the connectors, slide the fully insulated covers into place, and snap them shut over the joint. No crimping, no heat gun, no cutting into your existing charger cables. If you can plug in a trailer connector, you can install this. That counts for a lot when you're doing the work yourself at the dock with limited space and worse lighting.\u003c\/p\u003e\n\u003cp\u003eWhere does it earn its keep? Sailboats with the house bank buried in a lazarette. Center consoles where the charger lands on a bulkhead and the batteries sit low and aft. Any layout where the charger and the bank ended up farther apart than the factory leads planned for. The 5-foot length gives you room to route the cable cleanly instead of stretching a short lead into a strained, hard bend.\u003c\/p\u003e\n\u003cp\u003eThe dual inline fuses are the detail people overlook. Any time you extend a DC run, you're adding length that needs its own protection, and a lot of extenders leave that to you. This one builds it in on both legs, so a chafed jacket or a dead short at the far end blows a fuse instead of cooking the wire. It's the kind of thing you don't think about until it saves you, and it's already handled here.\u003c\/p\u003e\n\u003cp\u003eA couple of real-world notes from folks who've run these. On a 5-foot run at charging currents this gauge is fine, but if you're feeding a heavy continuous load you'll see a little voltage drop, so size your wire to the job. If you run in salt water, a smear of dielectric grease at the plug interface and a heat-shrink boot over the joint will keep corrosion off the pins and save you a rebuild down the line. The cable jacket is on the stiff side, so give it a gentle radius rather than forcing a tight 90 in a cramped locker.\u003c\/p\u003e\n\u003cp\u003eGuest has been building marine electrical gear for a long time, and this extender fits right in with that line of chargers, switches, and maintainers. It's engineered for boats, tested against the vibration, moisture, and temperature swings that kill cheaper parts. When the connection between your charger and your bank has to hold up for years of charge cycles, that pedigree is worth something. It's a simple part that solves a common, annoying problem. If your charger leads don't reach, you don't need to re-run the whole harness. You just need the right extender, fused and tinned and ready for the water.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eRated for 30 amps, enough headroom for on-board marine battery chargers with ring terminal leads\u003c\/li\u003e\n  \u003cli\u003eCorrosion-resistant tinned 12 AWG copper wire holds up to salt air and damp bilges\u003c\/li\u003e\n  \u003cli\u003eGold-plated hardware keeps the connection clean and low-resistance\u003c\/li\u003e\n  \u003cli\u003eDual inline waterproof fuses protect the extended run without a separate fuse block\u003c\/li\u003e\n  \u003cli\u003eSlide-and-snap fully insulated connection covers, no cutting, stripping, or splicing\u003c\/li\u003e\n  \u003cli\u003eColor-coded leads make it obvious which side is positive and which is negative\u003c\/li\u003e\n  \u003cli\u003e5-foot length reaches batteries tucked into remote or aft compartments\u003c\/li\u003e\n  \u003cli\u003eUniversal fit for on-board marine chargers that use ring terminal cables\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Guest reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat does the Guest 27505 actually do?\u003c\/summary\u003e\n    \u003cp\u003eIt extends the DC cable between an on-board marine battery charger and the battery bank when the factory charger leads don't reach.
