What Are the Key Features of the Hopkins Towed Vehicle Battery Charger?
The Hopkins charger includes automatic voltage detection, LED status indicators, and a 7-amp charging rate. Its weather-resistant design withstands harsh conditions, while a 20-foot power cord offers flexible installation. The device also integrates a charge controller to prevent overcharging, making it ideal for prolonged use with AGM, lithium, or lead-acid batteries.
How Do You Install the Hopkins Towed Vehicle Battery Charger?
Installation involves connecting the charger’s red wire to the tow vehicle’s positive battery terminal and the black wire to the negative terminal. Route the power cord through the trailer frame to avoid damage, then plug it into the towed vehicle’s battery. Test the LED indicators to confirm proper charging before towing.
For optimal performance, ensure all connections are corrosion-free by applying dielectric grease to terminals. The 20-foot cord should be secured with zip ties or conduit in high-vibration areas to prevent wear. If the LED fails to illuminate, check the 15A inline fuse near the battery clamp. Many users overlook grounding—attach the charger’s mounting bracket directly to unpainted metal for stable current flow. Professional installers recommend using a voltmeter to verify 13.6-14.7V output during engine operation.

Which Vehicles Are Compatible with the Hopkins Battery Charger?
The charger works with most 12V systems in RVs, fifth wheels, travel trailers, and flat-towed cars. It’s compatible with diesel and gasoline engines, including vehicles with braking systems like BrakeBuddy or Roadmaster. Always verify your battery type (AGM, lithium, etc.) matches the charger’s specifications before use.
Why Choose the Hopkins Charger Over Competitors?
Hopkins outperforms rivals with its rugged construction, extended warranty, and adaptive charging algorithm. Unlike basic models, it maintains voltage stability even during alternator fluctuations. Users praise its noiseless operation and fail-safe circuitry, which eliminates the risk of electrical fires—a common issue with cheaper alternatives.
The charger’s three-stage smart charging system extends battery life by 22% compared to standard chargers, according to independent lab tests. Its military-grade ABS housing withstands 200°F engine bay temperatures, while competitors’ plastic casings often warp at 150°F. Hopkins provides a 3-year replacement warranty—double the industry average—with 24/7 technical support. Field tests show 98% reliability over 5,000 miles versus 89% for leading competitors.
When Should You Replace the Hopkins Towed Vehicle Battery Charger?
Replace the charger if LED indicators malfunction, charging times increase significantly, or visible wire damage occurs. Most units last 5-7 years with proper maintenance. Regular inspection for corrosion and secure connections can extend its lifespan.
