At 120 watts through a single outlet, it's sized for laptops, chargers, and small electronics, and it plugs right into a 12 volt socket with the included cord-set. Clean power, no install headache.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Samlex PST-120-12 is a compact pure sine wave inverter that turns your boat or RV's 12 volt battery into clean 120 volt household power. It's rated at 120 watts continuous with a single AC outlet, and it ships with a cigarette lighter cord-set so you can plug it straight into a 12 volt accessory socket and be running in about a minute. No wiring, no drama.\u003c\/p\u003e\n\u003cp\u003eHere's why pure sine wave matters. A lot of cheap inverters put out a modified or stepped waveform that works fine for a light bulb but makes sensitive electronics buzz, run hot, or throw errors. This one produces a true sine wave, the same shape as the power at your house. That means laptops, camera and drone battery chargers, small TVs, and other sensitive gear run quietly and cleanly off it. If you've ever had a charger whine or a screen flicker on a cheaper unit, you already know the difference.\u003c\/p\u003e\n\u003cp\u003eThink of this as a small-electronics inverter, not a whole-boat solution. At 120 watts and 1 amp of AC output, it's sized for the stuff you actually carry on the water: keeping a laptop topped off on a long passage, charging a couple of camera batteries between dives, running a small flat-screen at anchor, or powering a phone and tablet on a weekend trip. It's not going to run a coffee maker, a microwave, or a hair dryer. Those pull far more than 120 watts, and this inverter will alarm and shut down rather than cook itself. Match the load to the rating and it'll run happily for years.\u003c\/p\u003e\n\u003cp\u003eEfficiency comes in at 88 percent, which is honest for a unit this size. At full output you're pulling roughly 11 amps off the 12 volt side, so it's worth keeping an eye on your battery if you're running it for a while on a small house bank. Plug it into a healthy 12 volt socket wired for accessory loads and you're fine. If your socket is on a thin, fused circuit shared with other gear, don't be surprised if you need to give the inverter its own feed.\u003c\/p\u003e\n\u003cp\u003eSamlex built in the protection you want on a boat. There's a low input voltage warning alarm that lets you know before you flatten the battery, plus short circuit, ground fault, overload, and reverse polarity protection. That reverse polarity protection is the one that saves you on install day, because a 12 volt system on a boat or camper is exactly where a quick, tired hookup goes wrong. The unit protects itself and gives you a chance to fix the connection.\u003c\/p\u003e\n\u003cp\u003eThe case is small, 7.44 inches long by 4.13 inches wide by just 1.2 inches tall, so it tucks into a dash cubby, a nav station drawer, or a locker without hunting for space. It does get warm under sustained load, which is normal, so give it a little air rather than burying it under a pile of gear. And a practical note from the water: any inverter can put a little electrical noise into nearby electronics, so if you run it right next to a VHF or a chartplotter and notice interference, move it a foot or two and route the cord away from your antenna leads.\u003c\/p\u003e\n\u003cp\u003eInstallation is about as simple as it gets. Plug the included cord-set into any 12 volt accessory socket, then plug your device into the inverter's outlet. If you'd rather mount it permanently, set it somewhere dry and ventilated, keep the DC run short and properly sized, and you've got a clean 120 volt outlet wherever you need one on the boat or in the rig.\u003c\/p\u003e\n\u003cp\u003eFor boaters and RVers who just need reliable, clean power for laptops, chargers, and small electronics without the cost and install of a big hardwired system, the PST-120-12 hits the mark. It's the kind of small, well-protected unit you plug in, forget about, and keep aboard for years.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003ePure sine wave output for clean, quiet power that sensitive electronics like laptops and camera chargers run on without buzzing or errors\u003c\/li\u003e\n  \u003cli\u003e120 watts continuous output, sized for small electronics: phones, tablets, camera batteries, and small TVs\u003c\/li\u003e\n  \u003cli\u003e12 volt DC input to 120 volt AC output, powered straight from your boat or RV battery\u003c\/li\u003e\n  \u003cli\u003e1 amp AC output through a single household outlet\u003c\/li\u003e\n  \u003cli\u003e88 percent efficiency, drawing roughly 11 amps off the 12 volt side at full load\u003c\/li\u003e\n  \u003cli\u003eIncludes a cigarette lighter cord-set with plug for plug-and-go use in any 12 volt accessory socket\u003c\/li\u003e\n  \u003cli\u003eLow input voltage warning alarm warns you before you drain the battery\u003c\/li\u003e\n  \u003cli\u003eShort circuit, ground fault, overload, and reverse polarity protection built in\u003c\/li\u003e\n  \u003cli\u003eCompact 7.44 by 4.13 by 1.2 inch case fits a dash cubby, drawer, or locker\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 Samlex America 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\u003eIs this a true pure sine wave inverter?\u003c\/summary\u003e\n    \u003cp\u003eYes.
