If you’re a DIY enthusiast or a professional tradesperson, you’re probably no stranger to the power tools offered by Dewalt. And what powers those tools? Batteries, of course!
But to keep those batteries juiced up and ready for action, you’ll need a reliable charger. Dewalt offers a range of battery chargers, and today, we’re going to compare two popular models: the Dewalt DCB101 and the DCB115.
Quick Verdict: The DCB101 is the dual-voltage fast charger with better portability and battery protection—ideal for users with both 12V and 20V MAX tools or those who need quick turnaround. The DCB115 is the compact, budget-focused 20V-only standard charger—fine for basic needs but limited in speed and versatility. Choose the DCB101 if you own 12V tools or charge frequently; choose the DCB115 only if cost is your sole priority and you only run 20V batteries.

DeWalt DCB101 vs DCB115: 10 Key Differences
1. Voltage Compatibility: 12V + 20V vs. 20V Only
DCB101: Charges both DeWalt 12V MAX and 20V MAX lithium-ion batteries. This dual compatibility eliminates the need for a separate 12V charger if you own tools from both platforms. I use 12V MAX screwdrivers and inspection lights alongside 20V MAX drills and saws—the DCB101 handles both without swapping chargers.
DCB115: 20V MAX only. If you own or acquire any 12V MAX tools, you’ll need a second charger. This is a genuine limitation that many users discover only after buying a 12V tool and finding their DCB115 useless for it.
Practical impact: The DCB101’s dual compatibility future-proofs your charging setup. The DCB115 locks you into 20V unless you buy additional hardware.
2. Charging Speed: Fast vs. Standard
DCB101: Fast charger design. A depleted 2.0Ah 20V MAX battery reaches full charge in approximately 30–35 minutes. A 5.0Ah battery charges in roughly 60–70 minutes. The faster charging is achieved through higher current delivery and more sophisticated charge management.
DCB115: Standard charger. Same 2.0Ah battery takes approximately 45–55 minutes. A 5.0Ah battery takes roughly 90–110 minutes. The slower speed reduces component stress and manufacturing cost but extends downtime.
Real-world math: If you run two batteries in rotation, the DCB101’s faster charge means less waiting and potentially fewer total batteries needed. On a production job site, 20–30 minutes saved per charge cycle adds up to hours per week.
3. LED Indicator: Dual-Color vs. Single-Color
DCB101: Dual-color LED (red to green). Red indicates charging; green indicates full charge. This is immediately clear from across a room—no ambiguity, no checking, no guessing.
DCB115: Single-color red LED. Stays solid red during charging and turns off when complete. There’s no “full” indication while the battery is seated—you must remove the battery or notice the light extinguished to know charging finished.
Operational impact: The DCB101’s green light prevents overcharging anxiety and lets you grab a fresh battery at a glance. The DCB115 requires more attention to avoid leaving batteries on the charger unnecessarily or pulling them early.
4. Physical Size and Portability
DCB101: Measures approximately 6.5″ × 4.5″ × 3.0″. Includes built-in cord wrap and carry handle. The cord wrap keeps the 3-foot power cord tidy during transport. The handle makes it easy to carry between job sites or from truck to work area.
DCB115: Measures approximately 5.5″ × 3.5″ × 2.5″. No cord wrap, no handle. The compact size fits easily in tool bags and drawers but requires manual cord management.
Portability verdict: The DCB101 is more functional for mobile work despite being larger. The DCB115 is better for stationary shop use or storage in tight spaces.
5. Weight
DCB101: Approximately 1.2 lbs. The extra weight comes from the dual-voltage circuitry, faster charging components, and cord wrap/handle hardware.
DCB115: Approximately 0.8 lbs. Lighter due to simpler electronics and lack of accessories.
Relevance: One pound is negligible for a charger that sits on a bench. For contractors who carry chargers daily in a tool bag, the DCB115’s lighter weight is marginally preferable—though the DCB101’s handle offsets this for hand-carrying.
6. Battery Protection and Charge Management
DCB101: Includes advanced thermal monitoring, cell balancing, and overcharge protection. The faster charging requires more robust safety systems to prevent battery damage from heat buildup. The charger communicates with the battery’s BMS (battery management system) to optimize charge curves.
DCB115: Includes standard overcharge and thermal protection. Functional but less sophisticated. The slower charge rate inherently generates less heat, reducing the need for aggressive thermal management.
Long-term battery health: The DCB101’s cell balancing and optimized charge curves may extend battery lifespan slightly, though both chargers are safe for daily use. The DCB101 is gentler on batteries despite charging faster—a counterintuitive result of better electronics.
7. Cord Management
DCB101: Integrated cord wrap on the housing. The power cord coils neatly around the charger body. This prevents cord tangling in tool bags and eliminates the “where’s my charger cord” problem.
DCB115: No cord management. The cord hangs loose or must be rubber-banded. In a cluttered tool bag, the cord tangles with other tools and gets damaged over time.
Durability impact: I’ve replaced DCB115 cords after the insulation frayed from bag abrasion. The DCB101’s cord wrap prevents this by keeping the cord protected and coiled.
8. Price and Value
DCB101: Typically $40–$60 standalone. Higher upfront cost but includes dual-voltage capability, faster charging, and better portability features.
DCB115: Typically $25–$40 standalone. Lower upfront cost but limited to 20V and slower charging.
Value per dollar: The DCB101 offers more functionality per dollar. The DCB115 is cheaper but does less. If you ever need 12V charging or faster turnaround, the DCB115’s savings evaporate against the cost of a second charger or additional batteries.
9. Heat Generation During Operation
DCB101: Runs warmer during fast charging. The charger body and battery surface become noticeably warm—hot enough that I avoid placing it on finished surfaces without a pad. The internal fan (if equipped) or passive cooling manages heat but doesn’t eliminate it.
DCB115: Runs cooler due to lower current delivery. The battery and charger stay lukewarm even during full charging. This is gentler on battery chemistry and safer in enclosed spaces.
Practical note: Both chargers are safe, but the DCB101 requires slightly more attention to placement—don’t bury it in a closed toolbox while fast-charging. The DCB115 is more forgiving of poor ventilation.
10. Ideal Use Case and User Profile
DCB101 best for:
- Users with both 12V and 20V MAX tools
- Professional contractors who need fast charge turnaround
- Mobile workers who carry chargers between sites
- Users who value cord management and clear charge status
- Anyone planning to expand into 12V MAX tools in the future
DCB115 best for:
- Budget-focused DIYers with only 20V tools
- Stationary shop setups where charging speed is irrelevant
- Backup or secondary chargers kept in vehicles or remote locations
- Users with ample battery inventory who never wait for charging
FAQs- Dewalt DCB101 vs. DCB115
Can the DCB115 charge 12V MAX batteries?
No. The DCB115 is 20V MAX only. The DCB101 is required for 12V MAX compatibility.
Is the DCB101 worth the extra cost?
Yes, if you need 12V charging or faster turnaround. The dual-voltage capability alone justifies the premium for mixed-platform users.
Will the DCB101 damage batteries by charging too fast?
No. The DCB101’s charge management system adjusts current based on battery temperature and condition. It is safe for all DeWalt 12V and 20V MAX batteries.
Can I leave batteries on either charger indefinitely?
Both chargers have auto-shutoff to prevent overcharging. However, removing batteries once charged extends long-term battery health.
Does the DCB101 work with FLEXVOLT batteries?
Yes, in 20V MAX mode. FLEXVOLT batteries charge on the DCB101 at 20V rates.
Which charger comes in DeWalt kits?
The DCB115 is more common in entry-level kits. The DCB101 appears in premium kits or as a standalone upgrade.
How long do these chargers last?
With normal use, 5–10 years. I’ve had DCB101s running daily for 6+ years without failure. The DCB115 has similar longevity but thinner cords wear faster without cord wrap protection.
Conclusion
The DCB101 vs DCB115 decision is straightforward: buy the DCB101 unless cost is your only consideration. The dual-voltage compatibility eliminates future charger purchases, the faster charging reduces downtime, and the cord wrap and handle improve daily usability. The DCB115 is functional but limited—adequate as a backup or for stationary 20V-only users, but a false economy for anyone with mixed voltage needs or production work requirements.
