CTEK

<h3>CTEK: The World Leader in Smart Battery Charging</h3><p>Few brands have shaped the landscape of vehicle battery care quite like <strong>CTEK</strong>. Founded in Sweden in 1997, CTEK launched onto the scene with a genuinely revolutionary product: <a href="/156-ctek-battery-charger-14307">the world's first &quot;smart&quot; battery charger</a>. That single innovation set the tone for everything that followed — a relentless focus on research, engineering precision, and user-friendly design that has made CTEK a household name among car enthusiasts, professional workshops, and motorsport teams alike.</p><p>Today, CTEK sells over one million battery chargers annually across more than 70 countries, and their reputation goes well beyond the numbers. Prestigious automakers including Porsche, Ferrari, and Aston Martin have chosen CTEK as their exclusive battery charging partner — a testament to the brand's standing in the performance and luxury vehicle world. Whether you're maintaining a daily driver, preserving a vintage collector car, or keeping a race car ready between sessions on track, CTEK's engineering philosophy remains the same: safe, reliable, and intelligent charging that extends battery life rather than simply topping it up.</p><h3>Patented Technology That Goes Beyond a Simple Charge</h3><p>What sets CTEK apart is their patented multi-step charging process. Rather than applying a constant charge and walking away, CTEK chargers work through a carefully sequenced program — including automatic desulphation, conditioning, absorption, and float maintenance — that treats the battery as a living system rather than just a container for electricity. Their chargers support a wide range of battery chemistries, including traditional lead-acid, AGM, EFB, and lithium (LiFePO₄), making a single CTEK unit versatile enough to handle virtually any vehicle in your garage.</p><p>The product lineup spans everything from compact <a href="/156-ctek-battery-chargers-200141">portable battery chargers</a> ideal for motorcycles and powersports, to high-output professional units like the PRO25S designed for busy service bays. Built-in temperature compensation ensures charging is always optimized for ambient conditions — a critical detail for anyone who stores a vehicle through cold winters or hot summers.</p><h3>A Complete Charging Ecosystem</h3><p>CTEK's innovation doesn't stop at the charger itself. Their range of <a href="/156-ctek-accessory-connector-12091">accessory connectors</a> — including the popular Comfort Connect pigtail harnesses and Comfort Indicator panels — make it easier than ever to maintain even the most difficult-to-reach batteries. Permanently mounted to the battery terminals, these connectors let you plug in and charge without ever fumbling with alligator clamps, and LED indicators keep you informed of battery status at a glance.</p><p>From weekend warriors and vintage car restorers to professional technicians managing a fleet of vehicles, CTEK has built a comprehensive ecosystem of charging solutions that meet every need. It's this combination of cutting-edge technology, proven durability, and thoughtful design that has kept CTEK at the top of the battery charging world for nearly three decades.</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.
