XZGm 56W 14V Fast Charger for NOCO Boost Jump Starter GB70

XZGm's 56W 14V replacement charger delivers the same XGC4 barrel-output power as NOCO Boost originals to recharge GB70, GB150, GB250+ and compatible jump starters faster and safely.

Whether you lost the original power brick or want a sturdier spare, this XZGm charger is built specifically for NOCO Boost UltraSafe lithium jump starters that use the XGC4 barrel connector. It supplies 14V at 4A (56W), matching the factory charging profile so your jump starter refills quickly without requiring a different cable or risky adapters. The unit features reinforced wiring, thermal protection and safety circuitry to reduce the chance of faults during charging.

How quickly will this charger restore my NOCO Boost jump starter?

This charger outputs 14V/4A (56W), which charges compatible NOCO Boost models much faster than typical 2A USB adapters. Expect significantly reduced recharge times versus low-power chargers while maintaining the correct voltage and connector type for XGC4-equipped units.

• 56W output equals up to 5× faster than a 2A USB wall charger
• Designed to match NOCO Boost GB70/GB150/GB250+ charge profile
• Full 14V DC output prevents under-voltage slow charging

Will this charger fit my jump starter and is it safe to use?

Use this XZGm charger only with NOCO Boost models that accept the XGC4 barrel connector (GB70, GB150, GB250+, GB251+, GB500, GB500+). The adapter includes over-voltage, over-current, short-circuit and overheat protection to guard the battery and the charger during normal use.

• Check your device port — works with XGC4 barrel-type inlet only
• Built-in safety systems reduce risk of electrical faults
• Reinforced cable and strain relief for long-lasting durability

What are the technical specifications and limits I should know?

The charger accepts universal AC input (100–240V, 50/60Hz) and outputs a steady DC 14V at 4A via the XGC4 connector. It is not compatible with 5V USB chargers, USB-C models, or jump starters that use a different barrel size—double-check your model before ordering.

• Input: 100–240V AC, 50/60Hz for worldwide use
• Output: DC 14V, 4A, 56W via XGC4 barrel connector
• Not for use with 5V or USB-C charging ports

How durable is the cable and housing for everyday use?

XZGm designed this charger with extra mechanical strength to withstand regular handling. The cable uses a thick pure-copper core and reinforced strain-relief at both ends to reduce connector stress and increase service life.

• Thick copper conductor for stable current delivery
• Strain relief prevents fraying at the connector joints
• Rugged plastic housing resists drops and surface wear

Who this is for: Drivers, fleet operators, RV owners and anyone who relies on a NOCO Boost jump starter and needs a fast, reliable replacement or spare charger. If your NOCO Boost model uses the XGC4 barrel connector and you want quicker recharge times with built-in safety features, this XZGm 56W 14V charger is a direct-fit, practical option. Do not purchase if your device uses USB-C or a 5V charging input—verify the port type before ordering.
