DeWalt 12V/20V/FLEXVOLT 2 Amp Charger

Why I added this charger to my bench

I keep a mix of DeWalt batteries in rotation—12V compact packs for inspection tools, 20V MAX packs for drills and impacts, and a couple of FLEXVOLT bricks for saws. I wanted a simple, dependable charger I could leave mounted near the door of my shop, something that would top off anything I throw at it without fuss. The DeWalt 2A charger fit that role: basic, cross‑platform compatibility, and no drama.

After a few weeks of everyday use, I see it as a steady, no‑nonsense option that favors reliability over speed. If you’re expecting a rapid charger, this isn’t it. If you need a quiet, compact unit that handles the entire DeWalt lineup from 12V to FLEXVOLT, it’s a solid choice.

Setup and first impressions

The charger is compact and light, with a familiar DeWalt design that matches the rest of the ecosystem. The housing feels durable enough for shop use, and the footprint is small enough to tuck onto a crowded bench or mount to a stud. There’s a simple two‑screw wall‑mount provision molded into the back; screws aren’t included, but installation took me just a few minutes. I mounted it near a 120V outlet and left enough clearance on both sides so batteries can slide on and off easily.

There’s a two‑stage LED indicator on the front. It’s not a multi‑segment fuel gauge; it’s a straightforward “charging vs. fully charged” status light. It’s bright enough to see across the room, and it’s easy to confirm a pack has seated correctly.

Charging performance: steady, not fast

This unit delivers up to 2 amps of charging current. In practice:

• A 12V compact pack topped off in roughly an hour from near empty.
• A 20V MAX 2Ah pack took a bit over an hour.
• A 20V MAX 5Ah pack took around three hours, which tracks with a 2A charger once you account for the taper near the end of the charge.
• A FLEXVOLT pack charged reliably, but you should budget several hours depending on capacity.

Times will vary with battery condition and temperature, but the pattern is clear: this is a dependable overnight or between‑tasks charger, not a pit‑stop fast charger. The upside to the modest current is that it runs cool and quiet. In my shop, I never heard a fan spin up (there isn’t one), and the housing stayed just warm to the touch, even with back‑to‑back 20V MAX packs.

If you routinely cycle multiple high‑capacity batteries during a single workday, I’d consider pairing this unit with a higher‑output DeWalt charger for fast turnarounds. But as a primary charger for light‑to‑moderate use—or as a secondary station mounted where you need it—it hits the mark.

Compatibility and everyday use

This is where the charger earns its keep. I’ve charged:

• 12V packs for inspection lights and compact drivers
• 20V MAX 2–5Ah packs for drills, impacts, and oscillating tools
• FLEXVOLT packs for saws

Each clicked in positively and started charging without any quirks. No adapters, no guessing which dock fits what—one station for the full lineup is one of the biggest practical benefits of DeWalt’s ecosystem, and this charger leans into that.

The indicator light is limited but effective. I can glance from across the shop: flashing while charging, solid when done. I don’t get precise percentage updates, but for workflow planning, “charging” versus “ready” covers most needs.

Design details that help

• Wall‑mounting: The two‑screw mount is simple and sturdy. A pair of wood screws into a stud held tight with no flex. If you wall‑mount, leave space above for taller FLEXVOLT packs.
• Cable routing: The cord exits cleanly and doesn’t fight the wall when mounted. I looped mine and set a small cable clip below the charger to keep things tidy.
• Battery seating: Packs slide on smoothly and lock with a reassuring click. Ejecting one‑handed is easy once you get the angle.

Nothing about the charger is flashy, and that’s fine. It’s a tool, not a conversation piece. The plastic shell is workmanlike and has shrugged off a few stray bumps from lumber and tool cases.

Heat, noise, and safety behavior

Running at 2A has two practical benefits: minimal heat and zero fan noise. Even with a big pack, the charger remains quiet and only slightly warm. That’s good for longevity in my experience.

I also noticed the charger being conservative with borderline packs—if a battery has just come off a tool and feels warm, the charger takes a beat before it ramps up. The two‑stage LED isn’t verbose about those states, but the behavior is predictable and points to sensible thermal management.

What could be better

• Speed: 2A is deliberate. If you rely on 5Ah+ packs all day, expect long charge times. This is the chief trade‑off.
• Status feedback: The two‑stage LED is simple, but you don’t get granular info like percentage or estimated time.
• No USB: There’s no auxiliary USB port for charging devices. Not a deal‑breaker, but worth noting if you like multi‑use chargers.

None of these are flaws so much as intentional omissions. The charger is designed to be simple and dependable, and it stays in that lane.

Who this charger suits best

• DIYers and homeowners with a couple of 12V/20V MAX packs who prioritize reliability over speed.
• Pros who want a quiet, secondary charger mounted at a fixed station—entryway, bench, or service vehicle—so a battery is always topping off.
• Anyone with a mixed DeWalt fleet (12V, 20V MAX, FLEXVOLT) who wants a single dock that accepts everything.

If you run a crew or cycle FLEXVOLT packs constantly, this works as a backup, but I’d invest in a higher‑output charger as your primary.

Alternatives inside the ecosystem

DeWalt’s lineup includes faster single‑port chargers and multi‑port options. A step up in amperage gets you significantly shorter charge times, particularly for 5Ah+ and FLEXVOLT packs, but expect more heat, fan noise, and a larger footprint. I’ve found the 2A unit to be the more pleasant daily companion when speed isn’t mission‑critical.

Warranty, support, and value

DeWalt backs the charger with a 3‑year limited warranty, 1 year of free service, and a 90‑day satisfaction guarantee. That’s more coverage than many generic chargers and aligns with what I expect from a flagship brand. Given the build, quiet operation, and broad compatibility, the value is strongest if you need a dependable, mount‑and‑forget station rather than a fast charger.

Practical tips from use

• Mount near the outlet you actually use most; convenience boosts the odds you’ll keep packs topped off.
• Leave vertical clearance if you’ll charge FLEXVOLT packs—they’re tall and need room to slide off.
• Rotate packs: top off a battery after each task instead of waiting until everything is empty. This charger’s pace rewards steady maintenance charging.

Recommendation

I recommend the DeWalt 2A charger as a reliable, all‑purpose station for 12V, 20V MAX, and FLEXVOLT users who don’t need rapid turnaround. It’s quiet, compact, wall‑mountable, and it charges every pack in the lineup without fuss. The main trade‑off is speed: high‑capacity packs take time. If your workflow depends on fast cycling, pair this with a higher‑output model. For everyone else—especially mixed‑fleet users and home shops—it’s a dependable, low‑maintenance charger that earns its spot on the wall.
