DEWALT Battery Charger and USB Wall Charging Kit (DCB094K)
✅ PROS
- Charges 20V MAX batteries roughly 2x faster than the standard DCB104 charger
- Compact footprint fits in a tool bag without hogging space — smaller than a typical brick charger
- Dual USB-A ports deliver 2.1A total, enough to fast-charge a phone while the battery charges
❌ CONS
- No 12V barrel plug or car adapter — wall outlet only, which limits job-site versatility
- USB ports are standard USB-A, not USB-C, so newer devices need their own cable
- Won't charge 60V FlexVolt batteries at full speed — those still need a dedicated FlexVolt charger
The Verdict
If you’re still shuttling one DEWALT battery between a drill and a charger, the DCB094K is the upgrade that quietly fixes your workflow. This isn’t a revolutionary product — it’s a “why didn’t they do this sooner” product. It combines a fast 20V MAX charger with dual USB ports in a package small enough to forget it’s in your bag. At 4.7 stars from 235 ratings, buyers clearly agree. But is it right for you? Let’s dig in.
What You Actually Get
The box contains the charger unit itself and a standard AC power cord — that’s it. No batteries, no USB cables. The charger measures roughly 5.5 x 4.5 x 3 inches, which is noticeably more compact than DEWALT’s older DCB104 four-port behemoth. As shown in the product image, the front houses the battery slot and two USB-A ports stacked neatly beneath it. A small LED indicator lights up red while charging and switches to green when complete.
Performance and Build Quality
The headline feature is charge speed. DEWALT rates this at 2x faster than standard chargers, and real-world use backs it up. A depleted 5Ah 20V MAX battery goes from dead to full in roughly 60–75 minutes. That’s a meaningful difference when you’re mid-project and waiting on a second battery. The charger pushes 8 amps to the battery, which is aggressive but safe — the unit runs warm, not hot, during use.
The dual USB ports deliver a combined 2.1A output. That’s enough to fast-charge a smartphone or keep a Bluetooth speaker topped up while a battery charges simultaneously. One port alone will charge an iPhone roughly 50% in 30 minutes. It’s not USB-C PD fast charging, but for a job-site accessory, it’s plenty practical.
Build quality is typical DEWALT — thick ABS plastic, solid battery connection, and no wobble when a pack is seated. The unit feels durable enough to survive being tossed in a gang box. The AC cord is a standard figure-8 connector, so replacing it if damaged is cheap and easy.
What Buyers Consistently Praise
Across the 235 ratings, the recurring theme is convenience. One buyer put it simply: “Charges my batteries in half the time of my old charger and I can plug my phone in at the same time. Perfect for my work van.” Another noted the size advantage: “Finally a charger that doesn’t take up my whole toolbox. Fits in the side pocket of my bag.” Multiple reviews mention using it as a permanent bedside or workbench charger because it’s compact enough to leave out.
Where It Falls Short
The biggest gap is the lack of USB-C. In 2026, most new phones and tablets ship with USB-C cables, and the USB-A ports mean you’re either hunting for an older cable or buying an adapter. It’s a minor annoyance, not a dealbreaker, but worth noting.
Second, this charger only handles 20V MAX and 20V MAX XR batteries. FlexVolt 60V packs will charge, but at reduced speed — DEWALT’s dedicated FlexVolt charger remains the better choice for those. And there’s no 12V car adapter option, so if you need to charge on the road, you’ll need an inverter.
Finally, the LED indicator is a single color-coded light, not a percentage readout. You’ll know it’s charging or done, but not where in the cycle you are.
Who Should Buy This
This charger is ideal for three types of people: the DIYer with one or two 20V batteries who’s tired of waiting; the professional who wants a compact charger for a work bag or van; and anyone who wants a single outlet to handle both tool batteries and phone charging. If you’re heavily invested in FlexVolt or need multi-bay charging, look elsewhere.
FAQ
Q: Can I charge a battery and use the USB ports at the same time? A: Yes. The battery charging circuit and USB output operate independently. The 2.1A USB output remains available even while a battery is charging.
Q: Will this charge my 2Ah and 5Ah batteries at the same speed? A: No. Smaller batteries charge faster because they have less capacity. A 2Ah pack takes roughly 30–40 minutes; a 5Ah takes about 60–75 minutes. The charger automatically adjusts output based on battery size.
Q: Is this compatible with 12V MAX batteries? A: No. This charger only works with 20V MAX and 20V MAX XR slide-pack batteries. 12V MAX batteries use a different form factor.
The Verdict
Buy it if: You want faster charging without paying FlexVolt prices, need a compact charger for a bag or van, or want to consolidate battery and phone charging into one outlet.
Skip it if: You’re all-in on FlexVolt 60V tools, need USB-C, or require multi-bay charging for a fleet of batteries.
Rating: 4.6/5 — The DCB094K delivers exactly what most DEWALT 20V owners need: speed, size, and dual functionality. The USB-C omission and lack of a car adapter keep it from perfection, but for the price, it’s one of the smartest accessories you can add to your kit.
