50A Smart Car Battery Charger, 6V, 12V and 24V Portable Car Charger (GENIUSPRO50)

*Compatible with all types of gas and diesel vehicles - Charge and maintain cars, automobiles, tractors, trucks, semi trucks, SUVs, RVs, campers, trailers, boats, classic cars, and more.

Discover the all-in-one professional solution for charging and maintaining automotive, marine and deep-cycle batteries: the NOCO GENIUSPRO50. With industry-leading features built for performance, reliability and versatility, this smart charger gives you full power in a compact, rugged unit.

• Charges 6 V, 12 V and 24 V battery systems — delivers up to 50 amps at 6 V and 12 V, and 25 amps at 24 V. 
• Compatible with a wide range of battery chemistries: flooded, gel, AGM, EFB, maintenance-free lead-acid and lithium-ion batteries. 
• Designed for professionals who demand uncompromising power and durability — built with ultra-flexible silicone cabling rated to -40 °C, braided nylon shielding for abrasion resistance, and heavy duty replaceable fuse for safety and long service life. 
• Dual-voltage power supply mode: deliver constant, clean 12 V (50 A) or 24 V (25 A) power output for demanding tasks such as ECU flashing, diagnostic testing or powered maintenance without ripple, noise or transient spikes. 
• Integrated thermal sensor automatically adjusts charging voltage and current to eliminate under- or over-charging in extreme ambient conditions—from cold down to -4 °F (-20 °C) up to hot climates of 122 °F (50 °C). 
• Detects very low battery voltages (as low as 1 V) and includes a “Force Mode” to manually initiate charging for batteries at zero volts—making it ideal for recovery of deep-discharged batteries.
• Automatic desulfation and acid-stratification repair modes for 6 V, 12 V and 24 V batteries: regenerate performance for stronger engine starts and extended battery life. 
• Built to handle large capacity batteries — up to 2,000 Ah for 6- or 12-V systems and up to 1,000 Ah for 24-V systems. 
• Rugged and compact design: dimensions of approx. 6.89" H × 12.44" W × 3.58" D (175 mm × 316 mm × 91 mm) and weight 5 lb (2.27 kg) for ease of installation and portability. 
• IP20 rated for protection in typical workshop or garage environments. 
  

What’s in the box: GENIUSPRO50 charger with interchangeable connectors, Genius PRO clamps with integrated eyelets, 10’ (3 m) extension cord, EVA hard case, self-tapping screws, and international power cables (Type A, C, G, I). Backed by a 3-year limited warranty. 

Why it stands out:
Whether you service cars, trucks, RVs, boats or heavy equipment, the GENIUSPRO50 gives you a professional-grade multi-voltage charger with advanced features rarely seen in this category. The combination of 6/12/24 V support, lithium compatibility, desulfation repair, cold/hot climate compensation and rugged build makes it ideal for high-demand applications and workshops.

For example, if you maintain classic cars, fleet trucks, agricultural tractors, or marine craft, you’ll appreciate being able to use one charger across multiple systems and battery types rather than having separate units. The ability to recover batteries down to zero volts and repair sulfation boosts your ROI on battery health and replacement costs.

Use this high-performing charger for: cars, SUVs, trucks, semi-tractors, trailers, RVs, campers, boats, marine craft, classic and vintage vehicles, deep-cycle battery banks, solar maintenance systems and anywhere you need serious battery support.
