Snap it onto the SAE connector, plug in your phone or handheld GPS, and you've got power at the helm with zero new wiring. Compact, black, and ready when you are.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you've already got a Battery Tender charging harness on your battery, this little adapter is one of the handiest upgrades you can make. It plugs straight into that same SAE quick-disconnect lead and gives you a 3-amp USB-A port. No splicing. No drilling a hole in the dash. You unplug the maintainer, snap this in, and you're charging.\u003c\/p\u003e\n\u003cp\u003eHere's the setup most folks run. You leave the Battery Tender SAE harness bolted to your battery terminals year-round, with the two-pin quick-disconnect plug tucked somewhere easy to reach. Normally that's where your battery maintainer clips on over the winter. This adapter uses the exact same connection. So the same lead that keeps your battery topped off in the off-season now powers your phone, your handheld GPS, a headlamp, or a tablet the rest of the year.\u003c\/p\u003e\n\u003cp\u003eThe output is a single USB-A port rated at 3 amps. That's enough to keep a modern phone charging while you navigate off it, or to bring a dead handheld back to life on a long day. Standard USB-A, so whatever cable you already carry will work. And that's worth saying plainly. The adapter ships without a cable. You bring your own, which is fine, because you probably have three of them in the glovebox already.\u003c\/p\u003e\n\u003cp\u003eIt's small. Three inches long, just over an inch wide, and about six tenths of an inch thick. Black housing. It tucks behind a switch panel, rides in a console cubby, or hangs off the harness under the seat on a bike. Battery Tender gear crosses over between boats, motorcycles, ATVs, side-by-sides, and RVs, and this adapter is no different. If it's got a 12-volt battery and a Battery Tender lead on it, this works.\u003c\/p\u003e\n\u003cp\u003eA few honest notes. This isn't a flush panel-mount socket. It's a portable dongle that lives on the quick-disconnect, so it's meant to plug in when you need it and come off when you don't. It's also not rated as a waterproof part, so keep it out of standing water and direct spray. On an open boat, tuck it into a dry console or a glovebox rather than leaving it exposed on the dash. Treat it like you'd treat your phone, and it'll last.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Anybody running a Battery Tender harness who's tired of a dead phone. Anglers who navigate off a phone or a handheld and need to top off between spots. Cruisers who want a charging point at the helm without paying an electrician to add a panel outlet. And honestly, the motorcycle and powersports crowd love these for the same reason, one lead does winter maintenance and summer charging both.\u003c\/p\u003e\n\u003cp\u003eOne thing worth understanding is the SAE quick-disconnect itself. It's the same flat two-pin connector Battery Tender has used for years across their maintainers and accessory leads. That standardization is the whole point. Buy one harness, leave it on the battery, and swap between the charger, this USB adapter, and any other SAE accessory without touching the wiring again. If you run more than one vehicle, you can move the adapter from the boat to the bike to the four-wheeler, as long as each one has its own SAE lead.\u003c\/p\u003e\n\u003cp\u003eOn the power side, 3 amps at 5 volts is real charging current, not a trickle. It'll run a phone's fast-charge on the USB-A standard and still have headroom for a tablet or a rechargeable spotlight. If your battery voltage sags low late in the day, output can taper a bit the way any 12-volt-to-USB converter does, but for day-to-day topping off it's got plenty of muscle for a single device.\u003c\/p\u003e\n\u003cp\u003eSetup takes about ten seconds. Find your quick-disconnect plug, line up the two-pin SAE connector, and push them together until they seat. Plug your USB cable into the port, and you're done. When you're finished, pull the connector apart and stow the adapter. There's nothing to wire, nothing to program, and nothing extra to buy except the cable you already own.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e3 Amp USB-A charging output, enough for phones, tablets, and handheld GPS units\u003c\/li\u003e\n  \u003cli\u003eSAE quick-disconnect plug snaps onto your existing Battery Tender harness, no new wiring\u003c\/li\u003e\n  \u003cli\u003e12 Volt DC input, works off any boat, motorcycle, ATV, or RV battery\u003c\/li\u003e\n  \u003cli\u003eCompact 3 in x 1.15 in x 0.6 in body tucks into a console or behind a panel\u003c\/li\u003e\n  \u003cli\u003eBlack housing keeps it low-visibility at the helm\u003c\/li\u003e\n  \u003cli\u003eTool-free connection, plug in and unplug in seconds\u003c\/li\u003e\n  \u003cli\u003eSingle USB-A port for the device you carry every day\u003c\/li\u003e\n  \u003cli\u003eShips without a USB cable, so use the one you already have\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 Battery Tender 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\u003eDoes this adapter come with a USB cable?\u003c\/summary\u003e\n    \u003cp\u003eNo. It ships without a USB cable, so you use whatever standard USB-A cable you already carry for your phone, GPS, or tablet.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eHow does it connect to my battery?\u003c\/summary\u003e\n    \u003cp\u003eIt uses an SAE two-pin quick-disconnect plug, the same connector on a Battery Tender charging harness.
