DCB104 4-Port Fast Charger for DeWalt 20V/60V Max - Rapid

Our review of the DCB104 4-Port Fast Charger finds it best suited for small workshops and tradespeople who need to keep multiple DeWalt 20V/60V batteries ready at once. The single biggest reason to consider this charger is its four simultaneous 3A outputs, which meaningfully reduce downtime compared with charging one battery at a time. In practice it behaves like a compact charging station with added USB power, and the built-in protections and LED indicators make it straightforward to monitor charging without guesswork.

Key Features

• Four-port rapid charging: Charge up to four 12V-20V MAX or 20V/60V FlexVolt packs at once to cut waiting times on busy job sites.
• 3A per port output: Each port provides a 3A output so batteries charge faster than standard single-port chargers, improving workflow efficiency.
• Wide compatibility: Works with a broad range of DeWalt style batteries including DCB120 series and FlexVolt packs so you can use existing batteries without adapters.
• USB charging: Built-in USB port supplies 5V at up to 2.1A for phones, tablets, or USB fans so the unit doubles as a small power hub.
• Humanized carry and mounting: A top handle, wall-mount slots and multifunction hooks let you place the charger where it fits your workspace and move it easily.
• Integrated safety features: LED status indicators and intelligent protection guard against overheating, overcurrent and overcharge to help extend battery life.

Who It's For

This charger is ideal for tradespeople, small construction crews, and serious DIYers who rotate multiple DeWalt 20V or FlexVolt batteries and want to minimize idle time. It suits users who value a compact, portable solution that can be mounted in a van, workshop wall or bench and that also charges a phone or tablet via USB.

It is less suited for someone who only owns a single battery or who expects ultra-fast rapid charge times comparable to manufacturer high-power single-bay chargers; if you only ever charge one pack, a single high-current charger may be more compact and quicker for that single battery.

Pros & Cons

Pros

• Simultaneous four-bay charging keeps multiple batteries ready and reduces downtime.
• Broad compatibility with 12V-20V MAX and 20V/60V FlexVolt battery series.
• USB port and mounting options add convenience on site or in the shop.
• Built-in LED indicators and safety protections provide peace of mind during charging.

Cons

• Some users report batteries that remained unresponsive after extended charging, so results can vary with aged or damaged packs.
• It is larger than single-bay chargers and takes more bench or van space if you only need one battery charged.

Our Verdict

The DCB104 4-Port Fast Charger is a practical multi-bay solution for users who juggle several DeWalt 20V or FlexVolt batteries and need them available throughout the day. Its simultaneous 3A outputs, USB charging, and mounting options make it good value for workshops and vans, though buyers with only one battery or heavily aged packs should temper expectations about revival of badly depleted cells.

Frequently Asked Questions

Will this charge FlexVolt 20V/60V batteries?
Yes. It is compatible with FlexVolt 20V/60V packs as well as standard 12V-20V MAX DeWalt style batteries.

Can it charge four batteries at full speed simultaneously?
Each bay provides a 3A output so all four can charge at the same per-port rate, which is faster than many single low-current chargers.

Does it protect batteries from damage?
The unit includes LED status indicators and an intelligent protection system for overheating, overcurrent, short-circuit and overcharge protection.
