DCB104 Replacement Dewalt 4-Port Fast Charger - Rapid Multi-Battery

Our review of the DCB104 Replacement for Dewalt Battery Charger Station finds it best suited for tradespeople and serious DIYers who juggle multiple DeWalt packs and need predictable, simultaneous charging. The bottom line: this 4-port station charges up to four 12V or 20V MAX batteries at once with a steady 3A per port and adds handy Dual USB-A and Type-C outputs, so it functions as both a multi-battery charger and a jobsite power hub. It is practical, compact, and built with clear LED diagnostics that make battery status easy to read.

Key Features

• Four simultaneous ports: Charge up to four Dewalt batteries at once to cut downtime on busy job sites and keep multiple tools ready.
• 3A per port output: Provides efficient and relatively fast charging for 12V and 20V MAX packs without stressing the cells.
• Universal Dewalt compatibility: Works with all 12V and 20V MAX batteries including FlexVolt and listed DCB models, so it fits across a full Dewalt tool ecosystem.
• Dual USB-A and Type-C ports: Lets you top up phones, tablets, or USB-powered tools while batteries charge, reducing the number of adapters needed on site.
• Six-layer safety protection: Built-in protections for short circuit, over-current, over-voltage, over-temperature, overcharge, and auto-shutoff help protect batteries and equipment.
• Wall-mount and portable design: Mounting holes and a foldable handle allow neat bench mounting or easy transport between jobs.

Who It's For

This charger is aimed at professional contractors, maintenance teams, and serious hobbyists who maintain several DeWalt batteries and need to minimize tool downtime. It is particularly helpful where multiple crews or machines share a small pool of batteries and a central charging station speeds turnaround.

It is less suitable for a casual homeowner who only owns one or two batteries and rarely needs simultaneous charging; a single-bay charger would be simpler and take up less space. Also, users seeking OEM branding should note this is a replacement station rather than an official factory unit.

Pros & Cons

Pros

• Charges four batteries at once, saving significant time on multi-tool job sites.
• Includes USB-A and Type-C outlets so you can charge devices alongside batteries.
• Solid build quality and reported to run cool, reflecting good thermal design.
• Broad compatibility with many Dewalt 12V and 20V MAX models, including FlexVolt variants.

Cons

• Not an official OEM Dewalt unit, which may concern buyers who prefer factory-branded chargers.
• While fast at 3A per port, charging time still depends on battery capacity and may not match higher-current single-bay rapid chargers.
