Designed for Safety

Each of NOCO Genius chargers contains multiple safety features to protect against user errors. These safety features include: reverse polarity, short circuit, open circuit, over-temperature, over-charging, and spark proof battery hook-up.

Energy Efficient, 90% Efficiency

The NOCO Genius charger is 90% efficient. Why is that important? The higher the efficiency level, the lower the power waste. Unlike other battery chargers, which waste almost half of their rated current, the NOCO Genius charger always performs at an optimal level.

24-Hour Mode

Leaving a battery in permanent maintenance charge mode reduces battery life. In fact, most battery manufacturers recommend against it. That is why this charger shuts off when the charge sequence is complete. Then turn "On" every 24 hours to ensure proper maintenance of your battery and making sure your batteries are 100% charged.

Made in the USA

Designed and manufactured in the USA. With a research and development facility in Arizona and manufacturing facility in Ohio, NOCO has the ability to consistently produce the highest quality and the lowest return in the industry.
