SYFLYH Charger Cable for NOCO Genius Boost Jump Starters — 14V 56W Power Adapter Kit with AC & 12V Leads

The SYFLYH 14V 56W charger cable is a replacement power adapter and cord kit designed to safely charge NOCO Genius Boost jump starters including GB70, GB150, GB250+ and GB500 series.

This compact adapter bundle supplies 14V DC at 4A (56W) to compatible NOCO lithium jump starter units, offering over-voltage, over-current and temperature protection through an integrated IC. The kit includes the main 14V power brick, AC mains lead, 12V car charging lead and spare 15A fuses, packaged in a fire-retardant shell with pure-copper conductors. It’s made as a like-for-like replacement when your original charger is lost, damaged or you need a second charging point.

Will this charger work with my NOCO GB70 or GB500 jump starter?

Yes — this adapter is built to match the voltage and current requirements of several NOCO Genius Boost models. It’s specifically intended for the listed 14V NOCO jump starters but is not compatible with devices that require USB-C charging or different voltage profiles.

• Compatible models: GB70, GB150, GB250+, GB251+, GB500, GB500+
• Output: DC 14V at 4A (56W) — matches NOCO charging specs
• Not for USB-C charging ports or non-14V devices
• Includes AC lead and 12V car charger lead for flexible charging

How does SYFLYH protect the jump starter during charging?

The adapter uses an integrated protection IC and a fireproof housing to reduce risk while charging. Built-in safeguards monitor voltage, current and temperature to prevent overloads or short circuits, and the pure-copper core improves heat dissipation and long-term reliability.

• Voltage, current and temperature protection via internal IC
• Fireproof PC shell lowers ignition risk
• Pure copper conductor for stable power delivery and durability
• Two 15A spare fuses included for quick field replacement

What’s included in the package and what are the specs?

The kit comes complete so you can start charging right away. It includes the 14V power adapter, an AC mains cable, a 12V car charging lead and two replacement 15A fuses, plus basic product specs printed on the adapter housing for easy reference.

• 1 × 14V DC power adapter (56W output)
• 1 × AC power cord (approx. 59 inches)
• 1 × car charger cord for 12V vehicle sockets (approx. 59 inches)
• 2 × 15A fuses and a fireproof PC shell for safety

How should I use and maintain the adapter for best results?

Use the adapter with compatible NOCO models and avoid forcing connectors or using the wrong voltage. Store cords coiled without tight kinks, replace blown fuses only with the included 15A type, and inspect the adapter periodically for damage to ensure continued safe operation.

• Connect AC cord to adapter, then to mains; or use car cord for 12V charging
• Replace fuses only with the supplied 15A spares
• Avoid exposing adapter to water or extreme temperatures
• Do not attempt to charge devices requiring USB-C or different voltages

Who is this for: The SYFLYH 14V 56W charger cable is aimed at owners of NOCO Genius Boost jump starters who need a reliable replacement or secondary charger — including professional mechanics, roadside assistance providers and everyday drivers who want a safe, durable charging option. If you own a compatible GB70, GB150, GB250+, GB251+, GB500 or GB500+ and require a straightforward, protected 14V charging solution with both AC and car cords included, this kit delivers plug-and-play convenience and practical safety features without unnecessary extras.
