A dead 20-volt battery halts your drill, saw, or leaf blower mid-task. This guide ranks dependable replacement chargers that revive your tools without a new battery system. You’ll find picks for single-battery homes, dual-bay stations for heavy users, and budget swaps for lost originals.
I’m Min — the founder and writer behind Gadgets Feed. 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.
When your drill battery dies mid-project, you need a fast, affordable charger. Here is the practical breakdown of the best 20 volt battery charger options on the market right now.
Our Picks at a Glance
How To Choose The Best 20 Volt Battery Charger
Choosing a charger hinges on matching your battery’s connector shape. Each tool brand uses a slightly different slide-pack or tower-style connector, so compatibility comes first — a charger from one brand physically won’t fit another’s battery.
Match the Connector, Not Just the Voltage
Even though they all say “20V MAX,” a BLACK+DECKER battery won’t slide into a DEWALT charger. Check the product description for your exact battery model numbers. Some replacement chargers list a whole family of compatible batteries (like the CMCB series from Craftsman), which makes them much safer bets than vague “universal” claims.
Look at the Amp Output for Speed
The amp rating tells you how fast the charger pushes power into the cell. A 2-amp charger refills a typical 1.5-Ah battery in about 40 minutes to an hour, while a slower 0.3-amp unit can take 3 to 5 hours for the same job. Daily users feel the speed gap as a coffee break versus a half-day wait.
Decide Between Single and Dual Bays
One battery means a single-bay charger suffices. Two batteries and a busy weekend call for a dual-bay charger to top both up simultaneously. Just remember that dual-bay models often charge two batteries at a slower combined rate than a single-bay unit charges one.

In‑Depth Reviews
1. BLACK+DECKER 20V MAX Lithium Battery Charger (LCS1620B)
Our pick — over 4.5★ from 15,000+ verified ratings; the strongest balance of quality and price.
The OEM-grade spare that refills a 1.5-Ah slide pack in 40 minutes flat.
This is the charger people reach for when the original goes missing — and it has earned a massive following for good reason. The 2-amp output pushes a 1.5-Ah battery to full in 40 minutes or less, which beats the slow stock chargers that many tools ship with. You get a green light that tells you when charging is happening and when the pack is done, so you are never guessing.
It is built for the 12V MAX and 20V MAX slide-pack batteries from BLACK+DECKER, and buyers report it slots straight into their existing setup without fuss. The most common story is a lost charger for a leaf blower or a drill being replaced for a fraction of the cost of a new tool. The crowd favorite status is well earned — the functionality and quality are the two things owners praise most, with hundreds of people calling it a solid, dependable workhorse.
The honest caveat is that charging speed and battery life get mixed feedback. Some owners find it quick, while others wish it pushed power faster for larger packs. It is also a single-bay unit, so if you run two batteries back-to-back all day, you will be swapping them in and out.
What Wins Owners Over
- Refills a 1.5-Ah battery in 40 minutes or less
- Clear green light shows charge status at a glance
- Fits both 12V MAX and 20V MAX slide-pack batteries
The Trade-Offs
- Single-bay only — no simultaneous charging
- Charging speed gets mixed reactions from owners
Grab it for: a dependable, widely-praised replacement that gets a single BLACK+DECKER battery back in action fast.
Look elsewhere if: you need to charge two batteries at once or want the absolute fastest charge for a big 20V pack.
2. for Hyper Tough 20V 2A Lithium-Ion Battery Fast Charger
A 2-amp speed upgrade that gets Hyper Tough batteries back to full in a fraction of the stock time.
If your Hyper Tough drill came with a painfully slow basic charger, this is the fix. The 2-amp output is a genuine step up, and owners describe it as a huge upgrade that gets 20V batteries to full power “in no time” compared to the original. The LED indicator system is refreshingly clear: green for standby, red for charging, and green again when the battery is full.
Safety is built in with short-circuit, over-charging, and overload protection, which means you can leave a battery on it without babysitting. Three sides of the housing are designed to dissipate heat, keeping things cool during long charge cycles. It is a small, compact black unit that takes up barely any bench space.
The main limitation is scope — it is made specifically for Hyper Tough power tools using 20V 2A lithium-ion batteries, so it won’t serve other brands. And with a 0.2 kg weight, it is light enough to toss in a toolbox, but it is a single-bay charger.
Why it wins: a genuine speed upgrade over the stock Hyper Tough charger, backed by clear LED feedback and real safety protections — the functionality is what owners praise most.
Know the limit: strictly a Hyper Tough 20V charger, so it is only useful if that is the battery platform you own.
3. DEWALT DCB1104 12V/20V 4 Amp Battery Charger
The fastest single-bay charger here, pushing a dead DEWALT pack to full in one hour or less.
This DEWALT charger refills a battery in an hour or less because it pushes 4 amps — twice the current of the common 2-amp units on this list. It works with both 12V and 20V DEWALT batteries, so you can charge any tool in a mixed workshop with one unit. The LED indicator (a small light that shows charging status) is more informative than most: it displays state of charge, when to replace the battery, battery temperature, and power line problems.
Owners mention it works just like the stock charger, taking batteries from dead to full without issues. Several note it is a great value compared to buying a replacement in-store, especially when you’ve lost the original. The 1.1-pound body has four plastic feet and slots to hang it on a pegboard, so it can live permanently on the workshop wall.
The caveat is packaging — it ships in a plain brown box without a user manual, which leaves some owners unsure about the advanced protection features. Functionally it performs exactly as expected, but don’t expect a retail-style unboxing.
Standout Strengths
- 4-amp output charges a battery in 1 hour or less
- Works with both 12V and 20V DEWALT batteries
- LED reports charge state, battery health, and temperature
Worth Knowing
- Ships without a manual in a plain box
- Single-bay — one battery at a time
Reach for it if: you want the quickest single-battery top-up available for a DEWALT 12V or 20V pack.
skip it if: you prefer a retail-packed product with documentation, or you need to charge two batteries simultaneously.
4. CMCB104 Replacement for Craftsman V20 Lithium-ion Battery Charger
A palm-sized Craftsman spare that lists a whole family of CMCB batteries in its compatibility range.
This charger is the definition of “small and portable” — a 3.94-inch cube that weighs just 1.1 pounds, easy to toss in a bag for jobs away from home. It lists compatibility with a broad range of Craftsman 12V and 20V lithium-ion batteries, including the CMCB201 through CMCB209 series, plus several others. That wide net makes it a safer bet if you own more than one Craftsman tool.
It refills a battery in about 1.2 hours, which is slightly slower than the DEWALT above but comfortably faster than the old-school chargers. Owners who couldn’t find the original charger were happy to land this as a suitable replacement at a reasonable cost, and they report it charges batteries quickly and works as intended. The build includes an intelligent protection system guarding against over-heat, over-current, and over-voltage.
The trade-off is the input — it accepts 100V-260V, so it is travel-friendly internationally, but the 2-amp output means it is not the fastest option for large-capacity packs. It is a single-port charger, so plan for one battery at a time.
Best for: Craftsman V20 owners who want a lightweight, portable spare with wide CMCB compatibility and a quick 1.2-hour charge.
Consider otherwise if: you need a heavy-duty dual-bay setup or faster-than-2-amp charging for big batteries.
5. AVID POWER 20V Max Lithium Ion Battery Charger
A direct replacement for lost Avid Power chargers, but only if you own the 1.5 or 2.0Ah battery.
Lost the charger for your Avid Power drill? This is the exact spare you need — provided your battery is the 1.5Ah or 2.0Ah version. The compatibility list is very specific and explicitly excludes the 3.0Ah batteries and a range of other tools, so check your model before ordering. Owners who matched it correctly report it works like a charm and is a perfect replacement after losing the original.
The LED diagnostics are straightforward: plug in the battery, and both green and red lights come on. When the red light goes out and green stays lit, the battery is full. It is a slow charger though — a full charge takes 3 to 5 hours — so it is best for overnight top-ups rather than quick turnarounds between jobs.
The honest catch is that compatibility and fit get mixed feedback. Some buyers found it didn’t charge their specific battery, so double-checking your model number against the list is essential. It is also a single-bay unit at just 3.84 ounces, making it one of the lightest chargers here.
What Works
- Direct replacement for the lost original Avid Power charger
- Simple two-light LED system for charge status
- Featherweight at 3.84 ounces
What to Watch
- Slow 3-5 hour charge time
- Strictly for 1.5/2.0Ah batteries — excludes 3.0Ah
- Compatibility issues reported for some models
Choose it if: you own an Avid Power 1.5 or 2.0Ah battery and want an affordable direct replacement that gets the job done overnight.
Think twice if: you have the 3.0Ah battery, a different Avid Power tool, or you need a fast daytime charge.
6. Powilling DCB102BP Replacement Charger for DeWalt
A dual-bay DEWALT charger that tops up two batteries in an hour and charges your phone on the side.
This is the charger for anyone who hates waiting on a single battery. It charges two DEWALT 12V-20V Li-Ion batteries at the same time and finishes each in one hour or less, thanks to advanced charging technology. The standout a neat extra is the pair of USB ports on the front, so it pulls double duty as a phone charger on the jobsite. Customers note it actually beats the original DEWALT brand charger on speed — one with two 8Ah batteries saw charge time drop from 4 hours to 2.5 hours while charging both at once.
Reliability is the most-praised aspect, with owners calling it dependable and saying it works just as well as the OEM version. It communicates with the battery pack to tune performance and extend life, and it comes with an 18-month warranty plus 45-day money-back coverage. The 110V-240V plug means it works across different regional power standards.
The one serious concern is battery life reports — a subset of owners found their batteries didn’t last more than 5 minutes after charging. This is worth flagging if you rely on this charger daily for critical work, though the majority report no such issue.
Why it stands out: the only charger here that charges two DEWALT batteries simultaneously and still has USB ports for your devices — reliability is what owners praise most.
The risk to know: a minority of reviewers point out shortened battery life, so it’s worth watching your packs closely after the first few charges.
7. COOMYXIN DCB102 20V MAX Battery Charger
A two-port DEWALT charger that saves money over the brand-name dual-bay option.
If you love DEWALT tools but not the price of DEWALT accessories, this dual-port charger is the cost-saving answer. It charges two DEWALT 12V-20V batteries at once, with a 90-minute charge time per battery. The compatibility list is wide, covering 12V, 14.4V, 18V, and 20V MAX models, making it a versatile backup for a mixed collection of tools. Owners specifically note it works great with third-party batteries too, which is a nice bonus for non-OEM packs.
Built-in safety mechanisms protect against overcharging, overheating, and short-circuiting, and the compact 5.9-inch design is easy to carry between job sites and the workshop. The value-for-money angle is the most-praised aspect, with buyers consistently calling it a great job for significantly less cost than the original.
The honest caveat is inconsistency. While many owners are satisfied, some report only one side works or that it charges slowly. The quality gets mixed feedback overall, so there is some unit-to-unit variation. Handle the battery gently when loading it, as one owner advises against forcing it in.
The Appeal
- Charges two DEWALT batteries simultaneously
- Works with 12V, 14.4V, 18V, and 20V MAX batteries
- Good with third-party batteries
The Risk
- Mixed reports on charging speed
- Some units reportedly only work on one side
Best for: DEWALT users on a budget who want a dual-bay charger and use third-party batteries.
Look elsewhere if: you need guaranteed consistent performance from every unit, since quality reports are mixed.
8. BLACK+DECKER 20V Lithium Battery Dual Charger (BDDC201B)
A compact dual-bay BLACK+DECKER station that charges two batteries in one outlet-saving unit.
This is the answer for BLACK+DECKER households that own two batteries and are tired of juggling outlets in the garage. It charges both 20V 1.5-Ah batteries in 3 hours, or a single 1.5-Ah battery in 1.5 hours — so you pick between speed and convenience. The two LED indicators sit on a single display surface with arrows showing the charge state of each battery, so you always know which one is ready.
Owners love that it frees up outlets in the shop and that they never have to wait for one battery to finish before starting the next. The dual charging capability is the most-praised feature, with people using it for weed eaters and other yard tools. It is part of the 20V MAX POWERCONNECT system, meaning one battery platform powers all your 20V BLACK+DECKER gear.
Two small notes from owners: when hot batteries are placed on charge, the unit may give a fault — just unplug and reseat the battery. And the charge light is very bright, which some find annoying in a dark garage. Neither is a dealbreaker, just a quirk to know about.
Why owners pick it: genuine dual-bay charging in a light, compact body that fits anywhere in the house — the dual capability is the top praise.
Worth noting: hot batteries can trigger a fault that needs a quick reseat, and the bright LED may irk you in a dim garage.
9. Hyper Tough HT Charge Lithium-Ion Fast Charger 20V MAX
The genuine Hyper Tough fast charger that takes a dead 20V pack to full in one hour.
If you want the actual Hyper Tough brand charger rather than a third-party replacement, this is it. It charges a 20V lithium-ion battery in 1 hour, which owners confirm — one notes their battery goes from fully expended to full charge in under an hour. The LED indicators keep you posted on progress, and the proprietary 20V battery connector ensures a proper fit with Hyper Tough tools.
Shoppers say buying this as a spare or to replace a lost original, making the replacement angle its most-praised feature. It suits anyone with multiple Hyper Tough tools because it works with all types of 20V lithium-ion tools in that platform. The 2-year warranty (a promise to repair or replace if it fails) adds genuine confidence that generic chargers often lack.
The trade-off is that this is a single-bay charger, so you can only top up one battery at a time. At 1.6 pounds, it is heftier than the compact third-party options, but that weight reflects the brand-name build. For a dedicated Hyper Tough owner, this is the safe, warranty-backed choice.
Why Buy the Brand
- Charges a 20V battery in 1 hour
- Genuine Hyper Tough fit and compatibility
- 2-year warranty included
The Limits
- Single-bay — one battery at a time
- Heavier than compact third-party chargers
Reach for it if: you want the confidence of a genuine Hyper Tough charger with a real warranty and a guaranteed 1-hour top-up.
pass on it if: you need dual-bay charging or want the lightest possible unit for a travel kit.
Understanding the Specs
Amp Output and Charge Speed
The amp rating is the single biggest factor in how fast a charger works. A 4-amp charger like the DEWALT DCB1104 refills a battery in about 1 hour, while a 2-amp unit takes roughly 40 minutes to 1.2 hours depending on the battery size. A slow 0.3-amp charger can take 3 to 5 hours for the same job. If you use tools daily, a higher amp rating means less waiting between tasks.
LED Indicator Meanings
Most modern chargers use colored lights to communicate status. A common scheme is green for standby, red for charging, and green again when full — though some brands add more detail. The DEWALT DCB1104 goes further, using its LED to signal battery temperature, when to replace the pack, and power line problems. Learning your charger’s light language saves you from guessing whether a battery is done.
