Specs are compiled from manufacturer listings and verified buyer reviews and can change over time — please confirm the key details on the product page before buying.

A quick note on sizes: not every pick below is the exact size or number you searched — where the exact one is scarce, the nearest same-type option that serves the same purpose is included so you get real, in-stock choices. Each pick’s actual specs are listed.

If you own one cordless tool and one battery, almost any charger will do. The trouble starts when you own three tools, four battery packs, and a single slow charger that forces you to stand around waiting. That is the real job this list solves: getting your spare packs filled fast, in the right connector, without overpaying for a brand-name replacement you do not actually need.

I’m Mohammad Maruf — the founder and writer behind KitchPrep. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.

Before you scroll, one honest heads-up: these are 20 volt class chargers, meaning they accept 18V-to-20V-class packs, and a few are cross-brand replacements rather than the exact original you searched for. The nearest same-type unit often does the same job for less. That is exactly why this 20 volt battery charger comparison focuses on connector fit and charge speed first.

How To Choose The Best 20 Volt Battery Charger

Buying a charger is really a two-step decision. First you confirm the connector physically matches your battery, then you decide how fast you need that pack back in the tool. Get the connector wrong and nothing else matters — the battery will not seat at all.

The connector is your first and only hard rule

Every brand uses its own battery shoe, the shaped slot where the pack slides in. A WORX charger will not accept a DeWalt pack, and a Hyper Tough charger will not accept a Craftsman one. Read your battery’s model number off the label before you order, because several chargers on this list are built for one brand family only and will not cross over.

Amp rating tells you how fast the pack refills

Amp rating is the amount of current the charger pushes into the battery, and higher means faster. A 4 A charger moves roughly twice the current of a 2 A unit, so the same pack fills in less time. Just remember that a large pack still takes longer than a small one no matter how strong the charger is.

Single bay or dual bay

If you swap one pack into one drill, a single-port charger is all you need. But if you run a trimmer, a blower, and a mower on the same weekend, a dual-port charger keeps one pack filling while the other is in the tool — which removes the idle waiting almost entirely.

In‑Depth Reviews

★ Best Overall

1. WA3875 Replace WORX 20v Lithium Battery Charger

Our pick — over 4.5★ from 300+ verified ratings; the strongest balance of quality and price.

Dual Port2-Hour Charge

Two WORX packs filling at once is what removes the weekend bottleneck.

If you run WORX 20V tools, this is the replacement that fills two packs in the time a stock single charger takes to fill one. Both ports finish inside 2 hours, and the 2 A rating means your spare is ready while the first battery is still working. The connector is a dedicated WORX shoe, so it seats on WA3578, WA3520, WA3525, WA3512 and WA3522 packs without wobble.

What wins people over is the build quality rather than the spec sheet — it is the single most-praised trait here, with charging speed and value close behind. Owners upgrading from the slow charger bundled with a WORX string trimmer report a dead pack reaching full in about 1.5 hours. The dual bays are the second draw: one battery in the tool, one on the charger, no downtime. If you want the exact words from the review pages: as owners put it, “This works great. Much faster than the OEM single charger.”

You get built-in protection against over-heating, over-current, over-voltage and over-charging, and the charger meets FCC, RoHS and CE testing standards (those are safety and environmental compliance marks). The honest catch: a 2 A charger (2 amps is the current flow) won’t refill a big battery as fast as a 4 A unit — the DEWALT DCB1104 on this list delivers twice the current at 4 A versus this unit’s 2 A. For most WORX owners that gap rarely matters, because the common packs are modest in size.

Reasons This Earns Top Spot

  • Both ports complete a charge inside 2 hours
  • Wide WORX compatibility across seven pack models
  • Four separate protection circuits built in
  • FCC, RoHS and CE testing compliance

Where It Falls Short

  • WORX connector only — no cross-brand packs
  • 2 A rate trails a 4 A charger on big packs

Reach for this if: you own WORX 20V tools and want your spare packs filled two at a time.

Look elsewhere if: your batteries are a different brand, because the WORX shoe will not accept them.

Fastest Refills

2. DEWALT DCB1104 12V/20V 4 Amp Battery Charger

4 A Output1-Hour Charge

The one that turns a dead DeWalt pack around in under an hour.

Speed is the whole story here. This charger fills a pack in 1 hour or less, and it does it at a 4 A output — double the 2 A of the WORX WA3875 and the Hyper Tough unit further down this list. If your workday stops when a battery dies, that gap matters more than any other number on this page. It covers both DeWalt 12V and 20V batteries, so one charger keeps an older drill and a newer impact driver both running.

Buyers report it as reliable equipment that just works — batteries click in and out cleanly, and it charges aftermarket packs as readily as genuine ones. The frustrations that drove the purchase are telling: people who replaced the low-powered charger that shipped with the DeWalt 12 volt drill say the original would have taken hours, while this one finishes fast. Four plastic feet keep it planted on a bench, and slots on the back let you hang it on a wall or shelf edge.

The honest gap: some units arrive in a plain brown box with no user manual, so you lose the printed explanation of the temperature and battery-replacement lights. The charger itself has a 1-hour rating against the 2-hour WORX above, so if speed is your priority this is the clear winner between the two.

On the indicator: the LED reports state of charge, when a battery should be replaced, battery temperature, power line problems and full charge — more feedback than most replacement chargers give you.

The one snag: a manual is not always in the box, so plan on learning the light patterns yourself.

Best fit: DeWalt owners who cannot afford to wait hours for a refill.

Not your pick if: your batteries use another brand’s connector, or you need two bays filled simultaneously.

Best Value

3. Leisuda 20V Max Dual Port Battery Charger Replacement for DeWalt

Dual PortDeWalt 14.4V/20V

The budget route to two DeWalt bays and a shot at reviving old packs.

Two things make this one worth your attention. It charges two 20V batteries at the same time, which cuts the queue when you are rotating packs through a drill and a saw. And it has a habit of waking batteries other chargers have given up on — owners mention packs that a DCB105 would no longer charge coming back to full life on this unit. It takes 14.4V and 20V DeWalt lithium packs including DCB206, DCB204, DCB208, DCB200, DCB201, DCB203, DCB140 and DCB141.

The build is genuinely portable, which is why it lives happily on a bench or in a truck box. Two LED indicators flash red while charging and go solid red when the pack is full, so you can read status from across the room. Multiple built-in protections guard against overcharging, overvoltage, overheating, overcurrent, overdischarge and short circuits, and it meets CE, FCC and RoHS standards with a 1-year warranty behind it.

The trade-off you should know before buying: charging speed draws mixed word of mouth. Some owners find it brisk, but others report a large 6Ah pack taking well over 7 hours to fill. If your packs are compact, you will likely be in the happy group — the snug fit and across-the-lineup compatibility are what owners keep coming back to.

Strongest card: reviving DeWalt packs that a stock charger has stopped accepting.

Weight to carry: slower than claimed on big 6Ah packs, and there is no bench-mounting option on the body.

Pick this one for: DeWalt owners with compact packs who want two bays without paying brand-name money.

Choose the DEWALT DCB1104 instead if: you regularly run large packs and need guaranteed speed.

Cross-Brand Pick

4. PCC692L 20V Fast Charger for Black and Decker and Porter-Cable Batteries

2 A OutputDual-Brand Fit

One charger that covers two brand families sitting in your garage.

Here is the rare case where a single charger serves two different tool brands. It replaces the Black and Decker 20V Max charger lineup and the Porter-Cable PCC691L, PCC692L, PCC699L and PCCB122C2 units, so if your shelf holds both Black and Decker and Porter-Cable packs, one part covers the lot. The 2 A output pulls a 20V 1.5Ah Black and Decker pack from dead to full in about 90 minutes, against roughly 3 hours on the original bundled charger.

Owners running a cordless mower, weed eater and edger call it clearly better than the charger Black and Decker supplied with their tools. The universal 100V to 260V input means it travels, and the LED indicator makes the charging state obvious at a glance. It carries CE, FCC and RoHS certification, and the cooling channel design works the heat away from the body during long sessions.

Read the compatibility note carefully, because this is the one pick with a hard limitation: it charges only Porter-Cable and Black and Decker 20V batteries. A DeWalt or WORX pack will not fit. Owners staying inside that pair of brands report a nicely built unit that does exactly what it promises.

What Buyers Keep Mentioning

  • 90-minute refill on a 1.5Ah Black and Decker pack
  • Serves both Black and Decker and Porter-Cable 20V packs
  • 100V-260V input travels well
  • CE, FCC and RoHS certified

Know Before You Order

  • Will not accept other brands’ 20V batteries
  • Single port, so one pack at a time

Worth grabbing if: your garage mixes Black and Decker and Porter-Cable 20V tools.

Pass on it if: you need a DeWalt or WORX fit, because this connector will not seat them.

Gentlest Charge

5. WETOOLPLUS 20V 0.7A Slow Battery Charger for Hyper Tough

0.7 A OutputOvernight Friendly

A slow, low-heat charger built for plugging in at bedtime.

This is the opposite approach to the desktop speed race. At 0.7 A it deliberately charges slowly, and the maker states that a 2.0Ah pack takes about 3 hours while a 4.0Ah pack runs closer to 6 hours. That gentler current keeps heat down and is the reason it suits an overnight routine — fill a pack while you sleep and it is ready for the morning. It fits Hyper Tough 20V Max battery packs including HT21-401-003-10, HT21-401-003-11, HY5601050516015 and ABP1820HDW, and replaces charger model ACG318W1U.

What stands out in owner experience is the fit — a precise match is the second most-praised attribute here after basic functionality. Owners who misplaced the charger bundled with a weed eater found this an exact swap, and the LED runs solid red while charging and solid green when full. Trickle mode kicks in automatically once the pack tops out, which keeps it from sitting hot on the contacts.

The obvious counterweight: if you need a pack back in twenty minutes, this is not the tool. Members who assumed it would be a drop-in got burned — one unit came back because the battery would not seat, so check your battery label against the compatibility list before ordering. For everyone else, this is the calm overnight option.

What it solves: dead-tired evening charging with no heat buildup on the battery.

What it will not do: get a pack back in the tool quickly, and it is Hyper Tough only.

Suited to: Hyper Tough owners who want a set-and-sleep overnight routine.

skip it if: your day depends on fast turnaround, or your pack is another brand.

Craftsman Workhorse

6. CMCB104 Replace for 20V Craftsman V20 Lithium-ion Battery Charger

1.2-Hour ChargeCraftsman 12V/20V

A straight Craftsman swap that fills a pack in about 1.2 hours.

For Craftsman V20 owners the draw here is a 1.2-hour charge time at a 2 A rating, on a charger that covers the whole CMCB battery family. That list runs CMCB201, CMCB202, CMCB203, CMCB204, CMCB205, CMCB209, CMCB100, CMCB101, CMCB102 and CMCB124, so whether your pack came in a kit or was bought loose, it should seat. The LED display reports charging status as you go, and it works with the 12V Craftsman packs too.

Customers note it behaves just like the original charger. One consistent theme: it performs at the same rate as the brand-name unit while costing noticeably less, and the review pages show people who could not find the genuine charger anywhere being glad this existed. Built-in protection covers over-heating, over-current, over-voltage and over-charging, and it meets FCC, RoHS and CE testing standards. The 240-volt input means it works on overseas mains as well.

One caution worth naming: a handful of units have arrived dead on arrival, so test yours on the first battery you charge and lean on the 30-day money-back and 1-year warranty if it misbehaves. The wider pattern is a reliable, well-priced substitute — a few failures against a large body of satisfied owners.

Steady performer: matches the original Craftsman charger’s pace while costing less.

Worth a test run: charge one pack the day it arrives so any faulty unit surfaces inside the return window.

Made for: Craftsman V20 owners who need one reliable bay at a sensible cost.

Not the pick if: you want two packs charging at once — the CMCB124 review below covers that.

Twin Bays

7. DCB102 20V MAX Dual Port Battery Charger Replacement for DeWalt

2 Ports12V-20V Fit

Two DeWalt bays on a bench without the brand-name price tag.

This is the value route to two charging bays for DeWalt packs. It takes 12V, 14.4V, 18V and 20V Max batteries in the same unit, which is helpful if your kit spans a few generations of tools. The indicator flashes red while charging and goes solid red once the pack is full, so a casual glance is enough to read status. Safety circuitry guards against overcharging, overheating and short-circuiting, and a compact body slips onto a shelf or under a bench.

Owners moving over from a genuine DeWalt charger often report faster charging at a fraction of the brand price. The dual bays earn their keep on bigger jobs — you can leave it running overnight and still have two packs waiting in the morning, which is exactly what the casual home user needs.

Be aware of the honest split here. Sentiment on build quality, charging speed and value is genuinely mixed, and a few reviewers point out the unit giving out after a few months or one side failing to hold. That puts it behind the higher-rated options in this guide on long-term feel, though the price-to-performance case is real for lighter use. Note also the short 6-month warranty — shorter than the 1-year coverage on the Leisuda dual port above it.

The Case For It

  • Two DeWalt bays in one unit
  • Reads 12V through 20V Max packs
  • Indicator light reports full charge clearly

The Honest Caveats

  • Long-term quality and speed draw mixed word of mouth
  • 6-month warranty is the shortest on this list

Good for: light-duty DeWalt users who want two bays without paying premium.

Consider the DEWALT DCB1104 instead if: you want single-bay speed and stronger long-term confidence.

Fast Twin Charging

8. CMCB124 Dual Port V20 Battery Fast Charger Replacement for Craftsman

4 A OutputDual Port

The two-bay Craftsman charger that clears both packs in one sitting.

This is the pick for anyone running several Craftsman V20 tools on the same day. It delivers 4 A total output, split as 2 A per port, and the maker states it fills two Craftsman 20V compact packs simultaneously in 60 to 100 minutes or less. That simultaneous fill is the win — you can swap a pair of packs straight back onto a drill and a saw while the third stays on the bench. Universal 110V to 240V input means it works on household mains anywhere.

Reliability and compatibility lead how owners talk about it, which fits a charger built for the CMCB201, CMCB202, CMCB204, CMCB206 and CMCB209 packs. The connection works across the V20 lineup and the fit is snug, so no fiddling to seat a pack. Indicator lights report charge and maintenance status, overload protection guards the cells, and a cooling system keeps heat moving during dual sessions. It carries FCC, RoHS and CE testing compliance plus an 18-month warranty and a wide support window.

The one real limit: a small number of units show a dead side, so it is worth confirming both bays fill on the first run. And take note of the compatibility boundary — Craftsman V12 and V20 series only, not the older 19.2V Bolt-On or DieHard packs. For current V20 owners, the speed on two packs at once is the whole reason to buy.

Speed that shows: two packs back in service inside 60 to 100 minutes, versus the single-bay CMCB104 above that fills one in 1.2 hours.

Test both ports: run a pack on each bay when it first arrives so any weak side is caught early.

Ideal for: Craftsman V20 users juggling multiple tools and battery packs.

Not for you if: you own 19.2V Craftsman packs, because that connector will not fit.

Budget Pick

9. Hyper Tough 20V 2A Lithium-Ion Battery Fast Charger with LED Indicator

2 A OutputHyper Tough Fit

An entry-level spare for Hyper Tough packs, with a clear three-light read.

For Hyper Tough owners this is the simple, low-cost way to keep a second charge point in the shop. It runs at 2 A, and the three-sided heat dissipation design moves warmth away from the body during the fill. The LED setup is unambiguous: green for standby, red for charging, green again when full. A 30-day refund window and round-the-clock support back it up, which softens the risk on an entry-level part.

Functionality is what carries the day here — it is the trait owners single out above all others, and the second theme is straightforward value. Owners describe the 2 A rate as much faster than the standard charger that came with their tools, with clear status lights cutting the guesswork. The current rating matches the WORX WA3875 at 2 A, so both fill at the same rate — this one simply fits the Hyper Tough shoe instead.

The trade-off is expected at this tier: protection covers short-circuit, over-charging and overload, but there is no second port and no fast charge beyond the 2 A rate. If your needs are one battery for one drill, that is ample. If your tool set is growing, the dual-port CMCB124 or the WORX WA3875 give you more headroom for a similar spend.

Simple and reliable: three-state LED and a 2 A charge make it a fuss-free spare.

Entry-level limits: one port only, so a second battery waits its turn.

Buy it for: a cheap second charge point for a single Hyper Tough tool.

Move up if: you juggle multiple packs and want two bays at once.

Understanding the Specs

Amp rating

Amp rating is the current a charger feeds a battery, measured in amps. A 2 A charger pumps roughly half the current of a 4 A one, so the same pack takes longer to top up. The DEWALT DCB1104 runs at 4 A against the WORX WA3875’s 2 A — that is the reason one finishes a pack in an hour and the other in about two. More current means more speed, and that is the number to compare when charge time is your priority.

Ports

Ports are the number of battery bays a charger holds. One port means one battery at a time, so a spare pack waits while the other fills. Two ports let you charge both packs at once, and this is the difference between a stalled weekend and one that keeps moving. The WA3875, Leisuda unit, DCB102 and CMCB124 are all dual-port picks, and on a two-port unit a large pack still takes longer than a compact one.

FAQ

Will a 20V charger work on my 12V tool battery?
No. A 12V pack uses a different connector and a lower voltage, so a 20V charger will not seat it. Some units here, like the DEWALT DCB1104 and the CMCB104, are designed to handle both 12V and 20V batteries from their own brand. Always check your battery’s own voltage on the label before ordering.
How do I know which connector my battery uses?
The connector is the shaped slot where the pack slides in, and every brand makes its own. Read the model number printed on your battery pack — for example a WORX pack starts with WA, a Craftsman pack with CMCB, and a DeWalt pack with DCB. Match that prefix to the charger’s compatibility list and you will get the right fit.
Is a higher amp charger always better for my battery?
Not always. A higher amp rating fills the pack faster, which is handy when you are working. A slower charger runs cooler, and the WETOOLPLUS 0.7 A unit is built around that idea for overnight charging. Both approaches have a place — pick speed when you need it, and a gentle rate when you have time.
Can a replacement charger charge two DeWalt packs at once?
Yes, if it has two ports. The Leisuda dual port DeWalt replacement and the DCB102 both carry two bays for DeWalt 12V to 20V packs. Two ports mean one battery fills while the other stays in the tool, which cuts your downtime. Note that a large pack on a two-port unit still takes longer to fill than a compact one.
Will this charger work with my Craftsman V20 battery from an older tool?
It depends on the series. The CMCB124 covers the Craftsman V12 and V20 series only, and will not fit the older 19.2V Bolt-On or DieHard battery lines. The CMCB104 replacement covers a wide CMCB battery list including CMCB201 through CMCB209. Check the battery model on your pack against those lists first.
How long does a 20V battery take to charge?
Times vary with charger amperage and battery size. The DEWALT DCB1104 fills a pack in 1 hour or less, and the WORX WA3875 completes both ports inside 2 hours. The CMCB124 dual port finishes two Craftsman compact packs in 60 to 100 minutes. On the slower side, the WETOOLPLUS 0.7 A runs about 3 hours for a 2.0Ah pack and closer to 6 hours for a 4.0Ah pack.
Are these chargers safe to leave plugged in overnight?
Most of them have built-in protection and are designed for convenience charging. The WETOOLPLUS unit switches to trickle mode once a pack is full so it stays cool, and it is openly pitched for overnight use. The Leisuda and CMCB124 also list overcharge and overheat protection. Even so, if a battery feels unusually hot while charging, unplug it and let it cool first.
Can I charge a Porter-Cable battery on a Black and Decker charger?
Yes, on the PCC692L unit, which is built for that crossover. It serves both Porter-Cable and Black and Decker 20V batteries, replacing the PCC691L, PCC692L and PCC699L chargers and the Black and Decker 20V Max units. It will not accept any other brand, though, so a DeWalt or WORX pack will not fit.
Do these chargers come with protection against overheating?
Almost all of them do. The WORX WA3875 covers over-heat, over-current, over-voltage and over-charging, and the Hyper Tough unit lists short-circuit, over-charging and overload protection. The DEWALT DCB1104 even reads battery temperature on its LED indicator. A cooling design, like the three-sided heat dissipation on the Hyper Tough, also helps keep the case cool during a fill.
Is a cheaper replacement charger as good as the brand-name original?
Often it charges just as well and costs less. The CMCB104 shoppers say the same charge rate as the original Craftsman unit, and the Leisuda dual port sometimes revives packs an original charger would no longer accept. The Leisuda replacement does draw mixed word of mouth on speed with large packs, so read the specs if you run big 6Ah batteries.

Final Thoughts: The Verdict

If your garage runs on WORX 20V tools, the WA3875 Replace WORX 20v Lithium Battery Charger is the pick to start with, because it fills two packs inside 2 hours and seats across the whole WORX 20V battery line. When raw speed and a single DeWalt bay matter more than port count, the DEWALT DCB1104 finishes a pack in an hour at 4 A. And for Craftsman V20 owners who rotate several tools on the same day, the CMCB124 Dual Port Craftsman Fast Charger clears two packs together in about an hour. Whatever you pick, match the connector to your battery label first — that one step is what keeps your 20 volt packs and your weekend plans both running.
