Its 9-step automatic program charges a drawn-down bank, then holds it without overcharging, so your batteries are ready when you are. Compact, universal 120 to 240 volt input, and built to hard-mount near the batteries and forget.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe NOCO GENIUS10 is a 10-amp smart charger that quietly does the job a lot of boaters ask two or three separate chargers to do. It handles both 6-volt and 12-volt batteries, charges them, maintains them, and keeps them healthy through the long off-season. If you've ever pulled the cover off your boat in spring and found a dead house bank, this is the little box that stops that from happening again.\u003c\/p\u003e\n\u003cp\u003eAt its core is a 9-step fully automatic charging program. You don't set a voltage, you don't watch a gauge, and you don't have to flip it off when the battery tops up. Connect it, plug it in, and it reads the battery, picks the right profile, brings it up to full, then drops into a maintenance mode that tops off only when the battery actually needs it. That last part matters. A cheap trickle charger just keeps pushing current and slowly cooks a battery over a winter. The GENIUS10 doesn't. It holds the charge and backs off, which is exactly what you want from something you'll leave connected for months.\u003c\/p\u003e\n\u003cp\u003eIt puts out 10 amps on both 6-volt and 12-volt banks, which is a genuinely useful amount of current. For a typical 100 to 150 amp-hour battery or house bank, that's enough to recover a drawn-down bank overnight and then hold it. On much larger banks or a deeply discharged battery, recovery is slower, so plan accordingly if you're running a big multi-battery system. For most center consoles, day boats, and mid-size cruisers, 10 amps hits the sweet spot between charge speed and gentle, battery-friendly output.\u003c\/p\u003e\n\u003cp\u003eOne of the quiet strengths here is the universal input. The GENIUS10 runs on anything from 120 to 240 volts AC at 50 to 60 hertz, so it doesn't care whether you're plugged into a North American dock, a European marina, or a generator with slightly wandering voltage. There's no switch to flip and no separate model to buy. That's one less thing to think about when you travel with the boat or keep it somewhere with less-than-perfect shore power.\u003c\/p\u003e\n\u003cp\u003eThe unit is compact, 7.1 inches long by 3.6 inches wide by 2.3 inches tall, so it tucks into a console cubby or an engine bay without a fight. NOCO includes a mounting bracket with a strap plus two self-tapping screws, so you can hard-mount it permanently near the batteries and leave it there. It also ships with interchangeable leads. You get clamp connectors for grabbing a battery on the bench and eyelet connectors with integrated ring terminals for a bolt-down permanent connection. Most boaters we talk to run the eyelets on the boat batteries and keep the clamps in the truck for jump-start duty. Swapping between them is a single quick-connect plug, so it takes seconds.\u003c\/p\u003e\n\u003cp\u003eA word on where you mount it. The GENIUS10 isn't a sealed unit, so it's not meant to live in the bottom of a wet bilge. Pick a dry, ventilated spot. And if the only good location is a little exposed, give it a simple protective cover to keep spray and corrosion off the connections. Treated right, it'll ride along for years.\u003c\/p\u003e\n\u003cp\u003eSo who's this for? Anyone who wants their batteries to still be there when they turn the key. It's ideal for winter storage maintenance, for keeping a starting battery and a house bank topped off between trips, and for reviving a battery that's been sitting too long. It's a real charger and a maintainer in one small package, and at this size and price it's an easy call for most boats under 30 feet. If you want to stop guessing about your batteries, wire in a GENIUS10 and forget about it.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e10-amp charging output on both 6-volt and 12-volt banks, enough to recover a 100 to 150 amp-hour battery overnight\u003c\/li\u003e\n  \u003cli\u003e9-step fully automatic program reads the battery, charges it, then maintains it without overcharging\u003c\/li\u003e\n  \u003cli\u003eUniversal 120 to 240 volt AC input at 50 to 60 hertz works on any dock or generator worldwide\u003c\/li\u003e\n  \u003cli\u003eInterchangeable leads: clamp connectors for the bench and eyelet ring terminals for a permanent bolt-down connection\u003c\/li\u003e\n  \u003cli\u003eCompact 7.1 by 3.6 by 2.3 inch body fits a console cubby or engine bay\u003c\/li\u003e\n  \u003cli\u003eIncludes a mounting bracket with strap and two self-tapping screws for a permanent install near the batteries\u003c\/li\u003e\n  \u003cli\u003eMaintenance mode tops off only when the battery needs it, safe to leave connected through the off-season\u003c\/li\u003e\n  \u003cli\u003eSingle quick-connect plug swaps between clamp and eyelet leads in seconds\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 NOCO 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 the GENIUS10 charge both 6-volt and 12-volt batteries?\u003c\/summary\u003e\n    \u003cp\u003eYes.
