CTEK

<h3>CTEK: The World Leader in Smart Battery Charging</h3><p><strong>CTEK</strong> — short for <em>Charge Technology</em> — has been at the forefront of battery charging innovation since its founding in 1997 in Dalarna, Sweden. Born from a simple but important mission: to fix the shortcomings of traditional chargers that too often damaged the very batteries they were meant to maintain, CTEK pioneered a smarter, safer approach to charging from day one. Today, the brand is recognized globally as the benchmark for intelligent battery care.</p><p>At the heart of CTEK's success is its proprietary multi-stage charging technology. Rather than simply pushing current into a battery and hoping for the best, CTEK chargers work through a carefully managed sequence of stages — including a desulfation phase that can recover deeply discharged batteries that conventional chargers would write off. This engineering-first philosophy earned CTEK an early OEM partnership with Porsche in 2002, a milestone that cemented the brand's reputation for quality among the world's most demanding automotive professionals.</p><p>From those roots, CTEK has grown into a truly global operation. The company now sells over one million <a href="/156-ctek-battery-charger-14307">battery chargers</a> annually across more than 70 countries, serving everyone from weekend hobbyists and motorcycle enthusiasts to commercial fleet operators and professional racing teams. Whether the application is a classic car tucked away in winter storage, a boat sitting at the marina, or an electric vehicle in need of a reliable charge, CTEK has developed a solution purpose-built for the task.</p><p>What truly sets CTEK apart is the breadth of its ecosystem. The brand's lineup goes well beyond the charger itself. <a href="/156-ctek-accessory-connector-12091">Accessory connectors</a> — like the popular Comfort Connect series — make it fast and simple to access batteries in tight, difficult-to-reach locations without juggling bulky clamps. Protective <a href="/156-ctek-bumper-1340">bumpers</a> wrap charger units in durable silicone rubber, shielding both the device and your vehicle's paintwork from accidental contact. And purpose-designed <a href="/156-ctek-carry-bag-52380">carry bags</a> keep chargers organized, protected from the elements, and ready to go at a moment's notice — whether you're heading to a track day or a remote campsite.</p><p>CTEK's product development is guided by a consistent set of principles: safety, dependability, and ease of use. Each charger is designed so that virtually any user — regardless of technical experience — can connect it confidently without risk of sparking, overcharging, or reverse-polarity damage. These qualities have made CTEK the trusted choice not only for private vehicle owners but also for workshops, dealerships, and motorsport teams worldwide.</p><p>With a continuous investment in research and development, CTEK has also expanded into electric vehicle charging solutions, reflecting the brand's commitment to staying ahead of where transportation technology is headed. From the original smart charger concept to the latest adaptive charging platforms, CTEK's story is one of relentless innovation in service of a simple goal: keeping every battery in peak condition.</p>

Product Details

The CTEK SSUP50 is an advanced AC soft starter designed specifically for RV air conditioning systems. This intelligent device reduces the initial surge current when your air conditioner starts up, allowing you to run your AC unit on smaller generators, limited shore power, or reduced inverter capacity.

Key Features:

  • Reduces startup current draw by up to 70%, preventing breaker trips and brownouts
  • Enables AC operation on generators as small as 2000 watts
  • Extends compressor lifespan by eliminating hard starts
  • Easy installation between thermostat and air conditioner
  • Compatible with most RV rooftop air conditioning units
  • Weatherproof enclosure for reliable outdoor mounting
  • Microprocessor-controlled soft start technology

Perfect for RVers who want to run their air conditioner without upgrading to a larger, noisier generator. The SSUP50 pays for itself by eliminating the need for expensive electrical system upgrades while protecting your valuable AC compressor from damaging hard-start wear.
