DONGNI 56W 14V Fast Charger for GB70 GB150 GB250+ — Replacement Cord with Reinforced Cable & Safety

Compact 56W 14V fast charger designed as a direct replacement cord for DONGNI-compatible GB70, GB150 and similar jump starter models.

This DONGNI replacement charger delivers a stable 14V, 56-watt output to refill compatible jump starters much faster than a standard 2A USB adapter. Built with reinforced wiring and multiple safety cutoffs, it’s intended as a drop-in power accessory for specified lithium jump starter models — check your device model carefully before buying because it is not compatible with 5V or USB-C variants.

How quickly will this charger restore my jump starter?

The 56W power rating significantly reduces recharge time compared with low-power USB chargers. Expect notably faster top-ups for the GB70 and GB150 family, helping you get back on the road sooner without long waits.

• 56-watt (14V) output for faster charging than typical 2A USB adapters
• Optimized for DONGNI-compatible GB70, GB150, GB250+ and similar models
• Reduces downtime by delivering higher current safely

Will this charger work with my device anywhere in the world?

Yes — the charger supports universal input voltage (100–240V), so it operates on standard international AC supplies when paired with the correct plug adapter. However, it only outputs 14V and is not intended for 5V or USB-C models, so verify your jump starter’s required input before use.

• Universal AC input: 100–240V for global use
• 14V output specifically for compatible jump starters
• Not compatible with 5V or USB-C chargers — check model sticker

What safety features and build quality does the charger offer?

The replacement cord is engineered for durability with reinforced wires and strain-resistant connectors to withstand repeated plugging and transport. It also includes multiple protections — over-charge, over-current, over-voltage, short-circuit and overheating safeguards — to protect both the charger and your jump starter during charging cycles.

• Reinforced cable and durable connector housings for longevity
• Built-in safety circuitry to guard against electrical faults
• Designed to match the charging profile of supported DONGNI models

What comes in the box and how do I confirm compatibility?

The package contains one 56W replacement charger and a user manual with connection and safety instructions. To confirm compatibility, compare your jump starter’s input voltage/specifications to the charger label and avoid purchasing if your device requires 5V or a USB-C input.

• Includes: 1 x 56W replacement charger and 1 x user manual
• Check your jump starter model: GB70, GB150, GB250+, GB251+, GB500, GB500+
• Not for USB-C or 5V-only units — read the manual first

Who this is for: This DONGNI 56W 14V replacement charger is aimed at owners of compatible lithium jump starters (GB70, GB150, GB250+/251+, GB500/500+) who need a faster, more durable charging cord than the low-power USB charger that may have come with their unit. It’s also useful as a spare or travel charger for drivers, fleet vehicles, and roadside toolkits where dependable, quicker recharging matters. If your device requires 5V or a USB-C input, choose a matching charger instead.
