WUKUR 56W 14V Fast Charger for NOCO GB70 GB150 GB250 GB500+ — 4A Rapid Replacement with Longer Cord

WUKUR's 56W 14V fast charger is a direct replacement power adapter designed to rapidly and safely recharge NOCO UltraSafe jump starters such as the GB70, GB150, GB250 and GB500+.

This compact 14V/4A (56W) charger is built to match the original NOCO adapter’s output while adding a longer cord and modern safety certifications. It accepts a wide AC input range (100–240V, 50–60Hz) so you can use it at home, in a workshop, or while traveling. The unit’s higher 4A output charges compatible lithium jump starters faster than a conventional 2A wall charger and includes multiple protections to preserve device and user safety.

How quickly will this charger refill my NOCO jump starter?

The WUKUR charger provides 14 volts at up to 4 amps, delivering a 56-watt output that shortens charge time compared with lower-current adapters. Charging speed depends on the battery state and model, but the higher current capacity enables noticeably faster top-up cycles.

• Output: 14V DC at 4A (56W total)
• Faster than typical 2A wall chargers—designed for quicker replenishment
• Compatible with GB70, GB150, GB250/GB250+, GB500+ models
• Performance varies by battery level and ambient temperature

Is this charger safe to use with my NOCO unit?

Yes — the charger includes multiple built-in protections and meets recognized safety standards. WUKUR lists ETL certification and compliance with RoHS, CE, and FCC, and the adapter incorporates overvoltage, overcurrent, short-circuit, and over-temperature safeguards to reduce risk while charging.

• ETL-tested and RoHS, CE, FCC compliant
• Protections: overvoltage, overcurrent, short circuit, over temperature
• Designed to match original NOCO adapter specifications
• Durable construction and quality components for steady output

Will this physically fit my jump starter and where can I use it?

The charger is built as a replacement for the NOCO UltraSafe series and uses the same output characteristics and connector type as the original adapter. It accepts common household AC voltages (100–240V), so you can plug it in virtually anywhere you have mains power, including international locations within that voltage range.

• Input: 100–240V AC, 50–60Hz — suitable for international use
• Longer power cord than some originals for flexible placement
• Connector and voltage matched to GB70/GB150/GB250/GB500+ models
• Confirm model compatibility before purchase to ensure proper fit
