<h3>About Samlex America</h3><p>Founded in 1991 and headquartered in Burnaby, British Columbia, <strong>Samlex America</strong> has grown into one of the most respected names in power conversion technology. With a commercial footprint spanning more than 90 countries, Samlex serves a remarkably wide range of industries — from communications and mobile fleet management to marine, RV, off-road, and fixed off-grid installations. Whether you need to power sensitive electronics in a remote cabin or keep a commercial work truck running smoothly in the field, Samlex engineers a solution built to last.</p><h3>A Complete Power Conversion Lineup</h3><p>What sets Samlex apart from one-trick-pony manufacturers is the sheer breadth and integration of their product ecosystem. Their catalog spans AC-DC power supplies, DC-DC voltage converters, solar panels and kits, battery accessories, transfer switches, and solar charge controllers. At the heart of the lineup, however, are two product families that have earned Samlex its stellar industry reputation: <a href="/7541-samlex-power-inverter-14297">power inverters</a> and <a href="/7541-samlex-battery-charger-14307">battery chargers</a>.</p><p><a href="/7541-samlex-power-inverter-14297">Samlex power inverters</a> are available in both pure sine wave and modified sine wave configurations, covering an enormous range of wattage requirements. Pure sine wave models — like the flagship NTX and EVO&trade; Series — deliver power that is virtually identical in quality to utility grid power, making them ideal for sensitive electronics, medical devices, and modern appliances. For users who need dependable DC-to-AC conversion in RVs, boats, or work vehicles, Samlex inverters are a go-to choice trusted by engineers and hobbyists alike.</p><p>On the charging side, <a href="/7541-samlex-battery-charger-14307">Samlex battery chargers</a> employ switched-mode technology to deliver efficient, quiet, and intelligent charging across 12V and 24V platforms. Their chargers are compatible with a wide variety of battery chemistries — including flooded lead-acid, AGM, GEL, and lithium-ion — making them a versatile fit for everything from marine deep-cycle banks to off-grid energy storage systems.</p><h3>Industries Served</h3><p>Samlex&apos;s versatility is one of its most compelling traits. Their products are deployed across an impressive range of real-world applications:</p><ul style="list-style:disc"><li><strong>RV &amp; Camping:</strong> Stay powered on the road or at the campsite without relying on shore power or noisy generators.</li><li><strong>Marine:</strong> Reliable power conversion for onboard electronics, navigation systems, and creature comforts on the water.</li><li><strong>Mobile Fleet &amp; Work Trucks:</strong> Keep tools, lighting, and communication equipment running efficiently from your vehicle&apos;s battery system.</li><li><strong>Fixed Off-Grid:</strong> Pair Samlex inverters and chargers with solar panels for a complete, self-sufficient energy system.</li><li><strong>Communications:</strong> Mission-critical backup power for radio base stations, repeaters, and 24/7 communication infrastructure.</li><li><strong>OEM &amp; Commercial:</strong> Custom power solutions built to specification for industrial and commercial integration projects.</li></ul><h3>Built on a Foundation of Reliability</h3><p>Samlex&apos;s commitment to engineering quality is evident in the protection features baked into their products. Many units include multiple layers of fault monitoring — scanning for adverse conditions thousands of times per second — along with thermal management systems that activate cooling only when necessary to reduce noise and energy draw. It&apos;s this level of attention to detail that has made Samlex a trusted partner for demanding commercial and industrial markets worldwide for over three decades.</p>

everything seems to be going ok thinks

easy to use

Searched for a number of days and Autoplicity had the best price by far!! Thanks Autoplicity!!!

found what i wanted , hoping there the right one ..

Excellent prices, fast shipping, good customer services. I'm a very happy customer and I will buy again from them.

Phone service was quick and personable wanting to solve my problem immediately. The weight of my package was wrong causing shipping to be $300 to ship a gas can but was fixed right away. Prices were great! I would purchase through them again!

I will use this site for all my "hard to find" car parts!!!!

Excellent, except I couldn't find where to enter my 20OFFSHIPPING Coupon Code.

I ordered a Thule 9002 Raceway Bike Carrier on Sunday, April 8 and received the product by Fedex on Wednesday, April 11 with just regular shipping. That is fast service. And the price was $43 cheaper than any other site on the internet (including shipping). I haven't had a chance to use the bike carrier yet but it appears to be new and as advertised with no issues as of this writing. I would definitely recommend this retailer for your next purchase. Order Number: 9111

Awesome awesome awesome so glad I was able to get what I needed for such a great deal
