XZGm 56W 14V Fast Replacement Charger for NOCO Boost GB70 GB150 GB250+ — XGC4 Barrel, 4A Rapid Charge

Compact 56W 14V replacement charger engineered to restore NOCO Boost jump starters (with XGC4 barrel port) to full charge faster and with built-in protection.

If your NOCO Boost GB70, GB150, GB250+ or compatible model needs a direct-replacement wall charger, the XZGm 56W 14V unit is built to match the original power profile and connector type. It supplies DC 14V at 4A through an XGC4 barrel plug, delivering the same charging pace as factory adapters so your lithium jump starter is ready sooner. The adapter is intended exclusively for NOCO Boost models that use the XGC4 barrel port — it is not suitable for USB-C or 5V chargers.

How fast will this charger refill my NOCO Boost jump starter?

This XZGm charger outputs 56 watts (14V × 4A), which charges compatible NOCO Boost units significantly faster than low-current USB chargers. Expect substantially reduced recharge times compared with a typical 2A USB wall adapter.

• Output: DC 14V, 4A (56W) to match original spec
• Typical up to 5× faster than 2A USB-based charging
• Faster turnaround means the jump starter is ready for consecutive uses

Will it safely protect my jump starter and my outlet?

The charger includes layered safety features to guard against common electrical faults. It’s designed with a reinforced cable and internal protection circuitry to reduce the risk of damage during normal charging conditions.

• Over-voltage and over-current protection to prevent spikes
• Short-circuit and overheat safeguards built into the adapter
• Durable strain relief and thick pure-copper core cable for longevity

Which NOCO Boost models work with this adapter and what should I check before buying?

Use this XZGm charger only with NOCO Boost models that accept the XGC4 barrel connector. It matches GB70, GB150, GB250+, GB251+, GB500 and GB500+ when those units use the standard 14V barrel input.

• Compatible models: GB70, GB150, GB250+, GB251+, GB500, GB500+
• Not compatible with USB-C, 5V, or non-XGC4 port versions
• Confirm your device’s port type visually before purchase

What comes in the box and what limitations should I expect?

Inside the package you get a single 56W replacement charger with an attached cable and XGC4 barrel plug — no extra adapters or cables are included. The unit is a like-for-like charging replacement but not a universal power supply for unrelated devices.

• Includes: 1 × XZGm 56W 14V (4A) replacement charger with XGC4 connector
• Warning: not for 5V/USB-C NOCO models or devices with different barrel sizes
• Input: 100–240V AC, 50/60Hz for worldwide voltage compatibility

Who is this for? If you own a NOCO Boost jump starter that uses the XGC4 barrel port and you want a reliable, high-power replacement charger that restores battery capacity quickly while protecting the unit from common electrical hazards, this XZGm 56W 14V adapter is a practical, affordable choice. It suits drivers, fleet operators, roadside technicians, and anyone who keeps a NOCO Boost charged and ready. Double-check your jump starter’s input port before ordering to ensure compatibility.
