UCANUUP 56W AC Adapter Charger for NOCO GB Series — 14V 4A Replacement with 5.5x2.1mm Connector & Safety Certifications

UCANUUP's 56W AC Adapter Charger is a direct replacement charger designed to safely and quickly replenish NOCO GB-series jump starters with a 14V, 4A output.

If you own a NOCO GB70, GB150, GB250+, GB251+ or GB500 jump starter, this UCANUUP 56W AC adapter provides an efficient, certified way to keep your unit ready. The charger accepts 100–240V input for worldwide use, uses a standard 5.5 x 2.1 mm barrel connector, and includes multiple built-in protections to preserve both the charger and the battery it serves. Built with TPE-insulated wiring and safety certifications (CE/FCC/ROHS), it’s intended as a reliable aftermarket alternative when the original charger is lost or damaged.

How fast will this charger recharge my NOCO GB jump starter?

The adapter delivers a steady 14V at 4A (56W) output, which provides faster recharging than lower-powered USB or cigarette-lighter chargers. Actual charge time depends on the jump starter’s capacity and state of depletion, but the higher amperage shortens top-up cycles compared with trickle chargers. The charger also regulates current to avoid over-stressing the battery during bulk charge stages.

• Output: 14V, 4A (56W) stable power for quick charging
• Connector: standard 5.5 x 2.1 mm barrel for NOCO GB compatibility
• Input range: 100–240V AC for international use
• Charge control: regulated output reduces risk of excessive heat

Is this adapter safe to use with my NOCO GB250+ or GB500?

The UCANUUP adapter includes multiple safety features—over-voltage, over-temperature and short-circuit protection—designed to safeguard both the charger and the connected jump starter. It is CE, FCC and ROHS certified, meeting common electrical and environmental standards. While engineered for NOCO GB-series models listed, always connect in accordance with your jump starter’s user guide to ensure correct polarity and connector fit.

• Certifications: CE, FCC, ROHS verified components
• Protections: over-voltage, over-temperature, short-circuit prevention
• Material safety: halogen-free flame retardant construction
• Connector fit: 5.5 x 2.1 mm barrel matches NOCO GB input

What makes UCANUUP’s build quality different from other replacement chargers?

UCANUUP uses TPE (thermoplastic elastomer) for the cable instead of standard PVC, improving flexibility, toughness and recyclability. The TPE jacket resists ozone and is halogen-free with flame-retardant V0 performance, which adds a layer of safety during heavy use. The adapter housing and internal components are designed to provide stable output and long-term reliability under normal charging cycles.

• Cable: flexible, elastic TPE wire for durability and easier handling
• Environmental: partially recyclable, halogen-free material choices
• Fire safety: V0-rated flame retardant properties
• Performance: stable 14V/4A output for consistent charging
