Frequently Asked Questions (FAQ)

Q: Why do other chargers spark when connected to the battery, and does this one do the same?
A: Standard high-current chargers often lack terminal isolation, causing an electrical arc (spark) when making contact. Our charger is engineered with a proprietary DC output anti-spark function and reverse polarity protection[cite: 2], ensuring a smooth, arc-free connection.

Q: Will this charger function correctly if the AC power source is unstable?
A: Yes. Many standard models require a strict 110V or 220V input. Our device features a wide AC input range spanning from 90VAC to 264VAC[cite: 2]. This design ensures stable charging even when drawing power from fluctuating generators or campground pedestals.
