Short answer: Choose the RYOBI P137 if you need documented simultaneous charging of one 18V ONE+ and one 40V battery. Choose the PCG007 when its advertised charging examples fit your packs and reducing charger clutter matters, but confirm the exact manual before expecting two batteries to charge at once. Separate chargers remain sensible if you already own them, charge each platform independently, or do not need both battery types ready together.
The phrase “dual platform” means a charger accepts RYOBI’s 18V ONE+ and 40V batteries. It does not automatically mean that every dual-platform model charges two packs concurrently.

What the choice really comes down to
Owners of both RYOBI 18V ONE+ and 40V tools are deciding between one charger that supports both battery families and two separate chargers. The right answer depends less on the word “dual” and more on four practical questions:
Free tools Windows power users keep installed
One-click scans. No signup required.
- Do you need an 18V and a 40V pack charging at the same time?
- Which battery capacities and pack types do you own?
- Is a manufacturer-advertised fast-charge example more valuable to you than independent charging hardware?
- Would replacing chargers actually save space, outlets or setup time?
If simultaneous charging is the deciding requirement, the P137 has the clearest documented feature: RYOBI says its indicator lights show batteries being “Simultaneously Charged and Maintained,” and a retailer listing specifies one 18V and one 40V battery at once. The PCG007 supports both platforms and publishes fast-charge examples, but the available documentation does not establish simultaneous two-pack charging. Treat those as different products rather than assuming one inherits the other’s features.

What “18V/40V dual platform” means
Both the P137 and PCG007 are identified by RYOBI as compatible with its 18V ONE+ and 40V battery platforms. Compatibility is limited to those RYOBI systems; it does not make either charger a cross-brand charger, and an 18V battery is not interchangeable with a 40V tool simply because both can be placed on the same charger.
| Setup | 18V ONE+ support | 40V support | Two-pack behavior established by the supplied product information |
|---|---|---|---|
| RYOBI P137 | Yes | Yes | Yes: one 18V and one 40V battery simultaneously, with charge-and-maintain status indicators |
| RYOBI PCG007 | Yes | Yes | Not established; verify the exact model documentation rather than infer it from “dual platform” |
| Separate 18V and 40V chargers | Depends on the selected 18V charger | Depends on the selected 40V charger | Each unit operates independently; exact concurrency depends on having both units connected |
This distinction matters when a workday uses a 40V mower or blower while smaller 18V tools are also in rotation. A charger can accept both families without offering two active charging channels.
RYOBI P137: the clearest choice for concurrent charging
What is documented
RYOBI’s P137 product information specifically describes simultaneous charging and maintenance. The Home Depot Canada listing further describes charging one 18V and one 40V battery at the same time. That is the strongest evidence in this comparison for a reader who wants both platforms progressing together rather than waiting for one pack to finish before starting another.
The Tool Desk
Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →The P137 listing also describes a 6-foot cord. That can help when the charger must sit on a workbench, shelf or garage outlet that is not immediately beside the battery storage area. The cord length is a placement detail, not a guarantee that the charger can be used outdoors or in wet conditions; follow the safety and environmental instructions for the exact unit.
Who benefits most
- Households that routinely use 18V and 40V tools in the same session.
- Crews that want one 18V pack and one 40V pack replenishing without swapping chargers.
- Anyone who values an explicitly documented two-battery workflow over an unverified assumption.
What it does not prove
Simultaneous charging does not mean both packs finish in the same amount of time. Battery capacity, state of charge and pack type can make one indicator change before the other. The documentation also does not provide a like-for-like speed test against the PCG007 or against named separate chargers, so the P137 should not be presented as universally faster.

RYOBI PCG007: dual-platform support with advertised fast-charge examples
Published charging examples
RYOBI’s PCG007 page gives two model-specific examples: a 15-minute charge for a named 4Ah 18V EDGE battery and a one-hour charge for a named 6Ah 40V battery. The page labels these claims “FASTEST RYOBI 18V ONE+ CHARGER” and “4X FASTER 40V CHARGING.” They are manufacturer marketing claims tied to those examples, not guaranteed times for every battery pack or an independently tested comparison.
A different capacity, chemistry, temperature, starting charge level or battery family can change the time. Compare the exact battery and charger pair you own instead of applying 15 minutes or one hour as a universal result.

The PCG007 operator’s manual says charge time depends on the type of 18V or 40V battery pack. The available PCG007 documentation does not establish that two batteries charge simultaneously. “Dual platform” confirms that both voltage families are supported; it does not, by itself, describe two active charging bays.
If charging both packs at once is essential, look for an explicit statement in the exact PCG007 manual or product listing. If that statement is absent, plan your workflow as though charging is sequential and confirm with the manufacturer before buying.
Who should consider it
- Owners who prioritize the published fast-charge examples for compatible packs.
- People who want one charger to cover both RYOBI battery platforms and generally charge one pack at a time.
- Users willing to verify the current model documentation and their own pack compatibility before relying on a particular charging routine.
When separate chargers make more sense
You already own suitable chargers
If an 18V charger and a 40V charger are already in your garage, buying a dual-platform unit may add convenience but not solve a real problem. Two existing chargers let each battery family charge independently, and there is no evidence here of a universal speed or cost advantage for replacing them.

Your workload needs two independent charging channels
Separate units can be the straightforward answer when two packs must charge independently and you prefer not to depend on the behavior of a combined model. You can place the 18V charger near small-tool storage and the 40V charger near outdoor equipment, provided each location meets the manufacturer’s electrical and environmental requirements.
You have unusual or changing battery needs
A separate setup lets you replace or upgrade one charger without changing the other. That can be useful if your 18V collection grows faster than your 40V collection, or if a future battery requires a charger with features that a combined unit does not offer. Exact compatibility still has to be checked for each battery and charger pair.
You do not need a single-device footprint
Separate chargers use more physical hardware and usually require two storage spaces, but they can be easier to distribute around a workshop. The trade-off is not automatically “more expensive” or “faster”: the outcome depends on the specific chargers, battery packs and prices you select.
Side-by-side decision table
| Decision factor | P137 | PCG007 | Separate chargers |
|---|---|---|---|
| Supported platforms | RYOBI 18V ONE+ and 40V | RYOBI 18V ONE+ and 40V | One platform per charger, depending on the model |
| Simultaneous 18V + 40V charging | Documented: one of each at once | Not established in the available documentation | Yes when both chargers are connected and each accepts the intended pack |
| Published speed evidence | No like-for-like speed figure supplied | 15 minutes for a named 4Ah 18V EDGE example; one hour for a named 6Ah 40V example | No general speed result established; varies by models and packs |
| Best fit | Mixed-platform users who value documented concurrency | Users who value the published fast-charge examples and one-device convenience | Owners who already have chargers or need independent charging hardware |
| Space and cable considerations | One device; the listing describes a 6-foot cord | One device; confirm the current listing for physical details | Two devices and two power connections |
How to choose the right setup
- Inventory your batteries. Write down how many 18V ONE+ and 40V packs you own, their capacities and which tools consume them fastest. Do not use a charger’s headline time unless it names a battery like yours.
- Decide whether charging must overlap. If an 18V pack and a 40V pack regularly need to charge during the same work window, concurrency is a requirement, not a nice-to-have.
- Match the requirement to documentation. The P137 has an explicit simultaneous-charging description. For the PCG007, verify the exact manual or product listing before assuming two-pack operation.
- Check the speed claim against your pack. The PCG007’s 15-minute and one-hour figures apply to the named 4Ah 18V EDGE and 6Ah 40V examples. They are not blanket guarantees.
- Account for what you already own. Existing separate chargers may make a new dual-platform purchase unnecessary unless reducing clutter or adding a documented feature is worth the cost.
- Plan the physical location. Measure shelf depth, outlet access and cable reach. The P137 listing’s 6-foot cord may help in a particular layout, while a two-charger arrangement may distribute better across work areas.
- Recheck the exact model number before purchase. P137 and PCG007 are different products. Do not rely on a retailer title that drops or changes the model suffix.
Workload-based recommendations
Weekly yard work plus frequent 18V projects
Choose the P137 when the practical goal is to put a 40V pack and an 18V pack on charge together after a combined session. Its documented one-of-each behavior directly addresses that scheduling problem.
Occasional charging and an existing charger collection
Keep the separate chargers if they already cover your batteries and you rarely run both platforms down at once. The convenience of one enclosure may not justify replacing working equipment.

Fast turnaround for a compatible 18V EDGE pack
The PCG007 is worth considering if the manufacturer’s 15-minute example matches the 4Ah 18V EDGE battery you use and you have confirmed the current product documentation. Treat the figure as an advertised example, not a promise for larger or different packs.
Fast turnaround for a compatible 40V pack
The PCG007 page’s one-hour example is tied to a named 6Ah 40V battery. Check your exact 40V pack before using that number for planning, and remember that the published material does not establish simultaneous charging on this model.
Multiple operators or a shared workshop
Separate chargers can reduce contention when different people need to start charging different platforms independently. A dual-platform charger can simplify storage, but one device may become a single point of access during busy periods.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Charging workflow and safe verification
Regardless of which setup you choose, use the charger’s own instructions for battery placement, indicator meanings, temperature limits and fault handling. A practical verification routine is:
- Confirm that the pack is a RYOBI 18V ONE+ or 40V battery supported by the charger’s manual.
- Inspect the battery and charger contacts for dirt, moisture or visible damage before connecting power.
- Seat the battery fully and check that the indicator shows charging rather than a fault state.
- For the P137, place one 18V and one 40V pack on the unit only if both are listed as supported by your documentation, then check each status indicator independently.
- For the PCG007, use the manual’s charge-time guidance for the specific pack and do not assume that two inserted batteries are being charged simultaneously.
- Remove a pack when charging is complete if your storage and maintenance routine calls for it, and allow hot batteries to return to the permitted temperature range before charging.
Do not substitute a third-party battery, adapter or cord on the assumption that voltage labels alone establish compatibility. The platform designation is a RYOBI system specification, not a universal electrical standard.

Common mistakes and how to avoid them
Mistaking platform support for simultaneous charging
This is the central purchasing error. A dual-platform label answers “which battery families fit?” It does not answer “how many packs charge at once?” P137 documentation answers both questions; PCG007 documentation, as available here, answers only the platform-support question.
Applying a headline time to every battery
Charge times vary with pack type. The PCG007 manual explicitly makes that dependency part of its guidance, while the product page’s examples identify particular capacities. Use those figures only for the named examples.
Comparing chargers without matching packs
A fair speed comparison requires the same battery capacity, starting state, temperature and charging conditions. No like-for-like comparison of P137, PCG007 and named separate chargers is established here, so a universal winner cannot be declared.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Buying by a retailer title alone
Retail listings can shorten product names. Confirm whether the listing is for P137 or PCG007 and read the model-specific feature list. Do not assume that a feature described for P137 applies to PCG007.
Ignoring the outlet and workspace plan
One combined charger can reduce device clutter, while two chargers offer independent hardware and placement. Count outlets, measure the available shelf or bench area and account for cord reach before deciding that either arrangement is automatically tidier.
Bottom-line decision framework
- Pick P137: you own both platforms and explicitly need one 18V and one 40V battery charging at the same time.
- Pick PCG007: you want one charger for both platforms and the advertised 15-minute 4Ah 18V EDGE or one-hour 6Ah 40V example is relevant to your packs; verify the exact documentation first.
- Keep or buy separate chargers: you already have suitable units, need independent charging locations, or do not regularly charge both platforms together.
No setup wins every category. P137 has the clearest concurrency evidence, PCG007 offers specific manufacturer-advertised speed examples, and separate chargers maximize independent hardware. Match the purchase to your battery mix and charging schedule rather than treating “dual platform” as a complete feature description.
