The DeWalt DCB107 charger is a compact 12V/20V MAX lithium-ion charger that often comes bundled with DeWalt tool kits. It is not the flashiest charger in the lineup, but it has earned a reputation for reliable, no-fuss charging. If you need to replace a lost charger or want a spare for your garage or truck, understanding what this model can and cannot do will help you spend wisely.
This article covers the DCB107's specifications, battery compatibility, charging times, LED diagnostics, and practical ownership advice. You'll also see how it compares with faster DeWalt chargers, so you can decide whether it is the right fit for your tools and workflow.
DeWalt DCB107 Charger Specs and Compatibility
At its core, the DCB107 is a 12V/20V MAX charger built for DeWalt lithium-ion battery packs. It accepts standard 20V MAX batteries and 12V MAX batteries, which makes it a versatile option for mixed collections. It runs on 120V AC power in North America and uses a slide-in design that most DeWalt users already know.
The charger is small and lightweight, so it fits easily on a shelf or in a tool bag. Unlike high-output models with cooling fans, the DCB107 uses passive cooling. That means it runs silently and has fewer moving parts, though it also charges more slowly than premium units.
Battery Compatibility and Fit
The DCB107 works with DeWalt 12V MAX and 20V MAX lithium-ion batteries. Common 20V MAX packs such as the DCB201, DCB203, DCB204, DCB205, and newer DCB206 series are compatible. It does not charge older 18V NiCad, 14.4V, or other non-lithium platforms, so verify your battery family before buying.
Because it belongs to the 20V MAX ecosystem, this charger pairs with drills, impact drivers, reciprocating saws, circular saws, grinders, and outdoor power equipment. If you keep tools in two places, a second DCB107 can be handy for charging at home while another stays in a jobsite trailer.
Charging Speed and Battery Sizes
The DCB107 is a standard charger, not a fast charger. Small 20V MAX packs charge reasonably quickly, while larger 4.0Ah, 5.0Ah, and 6.0Ah batteries take considerably longer. As a rough guide, a 2.0Ah battery may charge in about an hour, while a 5.0Ah pack can take more than two hours.
That pace works well for homeowners who charge overnight or between weekend projects. Professionals who cycle through many high-capacity batteries may prefer the DCB115 or DCB118 for faster turnaround. Even then, the DCB107 is useful as a secondary charger for smaller packs or as a backup in a travel bag.
LED Diagnostics, Performance, and Ownership Tips
The DCB107 uses a simple LED indicator to show charging status. Typically, a blinking light means the battery is charging, and a solid light means it is fully charged. If the light stays off, the issue may be the outlet, the battery, or the charger itself.
Real-world charging speed depends on battery age, capacity, and temperature. A battery that is hot after heavy use may take longer to charge because the charger manages heat. Cold batteries can also charge slowly. These are normal protective behaviors, not automatic signs of failure.
Understanding the LED Signals and Troubleshooting
When you insert a battery into the DCB107, the LED should begin blinking to confirm the charging process has started. Once the battery reaches full charge, the light should remain solid. If nothing happens, reseat the battery firmly and test a different outlet.
A deeply discharged battery may need a few minutes before the charger recognizes it. Check the metal contacts on both the charger and battery for dirt, corrosion, or damage. If multiple known-good batteries fail to charge, the DCB107 is likely faulty and should be replaced rather than opened for repair.
Best Use Cases, Maintenance, and Safety
The DCB107 is ideal for DIYers, homeowners, and professionals who need a reliable backup charger. It is also a good choice for charging smaller 20V MAX batteries used in drills, drivers, and compact saws. If you rely on large batteries for heavy equipment, a faster charger will reduce downtime.
Keep the charger in a dry, ventilated area and do not cover it while charging. Wipe contacts with a dry cloth if they look dirty, and avoid yanking the cord from the outlet. Store batteries in a cool, dry place at partial charge when they will sit unused for months.
If you want a dependable charger for DeWalt 12V and 20V MAX batteries without paying for speed you may not need, the DCB107 is a practical choice. Check your battery lineup, think about how quickly you actually need to recharge, and keep a spare where it saves the most time. A charged battery is often what keeps a project moving.
