The short answer

For the widest selection of compatible bare tools, Ryobi’s 18V ONE+ platform is usually the best bet. Ryobi sells more than 300 ONE+ products, covering drills, saws, sanders, inflators, outdoor equipment, lighting, cleaning tools, and specialty tools. The range is unusually broad because the platform targets homeowners and light-duty users, not just construction trades.

That does not make ONE+ the best platform for every buyer. DeWalt 20V MAX, Milwaukee M18, and Makita 18V LXT offer stronger choices for demanding jobsite work. Their tools generally have tougher housings, better ergonomics, and more high-output models. The practical choice depends on whether “most tools” means the largest catalog or the best selection for your particular work.

Battery platform comparison

Tool counts vary by country, counting method, and whether manufacturers include kits, lights, bare accessories, and discontinued products. Treat the numbers as a guide, not a precise ranking. The important point is that Ryobi has the broadest spread of inexpensive household and outdoor tools, while the professional brands have deeper lineups in core trade categories.

Why Ryobi ONE+ has the most compatible bare tools

ONE+ has been around for decades, and Ryobi has kept the battery interface broadly consistent. A current 18V battery can run a large number of older and newer ONE+ tools, although newer high-demand tools may perform better with a larger-capacity pack.

The lineup includes normal power tools such as drills, impact drivers, circular saws, reciprocating saws, and angle grinders. It also includes tools that other platforms often skip: glue guns, fans, heated gear, compact vacuums, powered scrubbers, USB chargers, portable pumps, and several garden tools. If you want one battery family for occasional repairs, seasonal yard work, and household projects, Ryobi ONE+ bare tools are hard to match for breadth.

There are trade-offs. A compact 1.5Ah or 2.0Ah battery may run a drill or light for a long time, but it can sag under load in a circular saw or leaf blower. For high-draw tools, expect better results from a 4.0Ah, 5.0Ah, or larger pack. More capacity also means more weight: a 6.0Ah battery can make a small drill tiring during overhead work.

When a professional platform is the better choice

DeWalt 20V MAX is the strongest all-around alternative. It combines a very large catalog with broad availability at home centers and hardware stores. Its lineup is especially good for framing, remodeling, trim carpentry, concrete drilling, and outdoor equipment. A buyer who needs a cordless router, planer, track saw, oscillating tool, and jobsite vacuum will find plenty of compatible choices. DeWalt 20V MAX bare tools are often the easiest professional option to find locally.

Milwaukee M18 has fewer low-cost household products but a particularly deep trade and automotive range. Its impact wrenches, specialty plumbing tools, electrical tools, inspection equipment, and high-output saws are major reasons professionals stay with it. Milwaukee also has M12, a separate 12V platform. M12 tools cannot use M18 batteries, so buying into both systems increases cost even though they complement each other well.

Makita 18V LXT remains a strong choice for users who care about balance, low vibration, and a mature trade lineup. It has excellent saws, drills, sanders, grinders, and outdoor tools. However, Makita also promotes the 40V XGT line for higher-performance equipment. XGT batteries and tools are not interchangeable with LXT, so check the platform label before assuming a tool belongs to your existing system.

Compatibility, battery cost, and common mistakes

“Compatible” means the battery physically and electronically belongs to that platform. It does not mean batteries can safely cross between brands. Do not force a DeWalt pack onto a Ryobi tool or rely on an unverified adapter for high-current equipment. Adapters can remove protection features, create poor connections, and increase the risk of overheating or tool damage.

Also check voltage families within the same brand. Ryobi 18V ONE+ is not interchangeable with Ryobi’s newer 40V outdoor system. DeWalt 20V MAX and FlexVolt are related, but a 60V FlexVolt tool requires a FlexVolt battery; a standard 20V pack cannot power it. Milwaukee M18 and M12 are separate systems.

Battery cost can outweigh the price of the bare tool. A useful starter setup normally needs two batteries and a charger, not just one pack. Two 4.0Ah batteries are a practical minimum for rotating between a tool and the charger. For a mower, blower, grinder, or saw, budget for larger packs and possibly a second charger. Look for a battery and charger starter kit when entering a platform; kits are often much cheaper than buying those items separately.

Which platform should you buy?

Choose Ryobi ONE+ if you want the largest variety, buy tools occasionally, and prefer reasonable prices. It is the sensible choice for most homeowners, especially when the tool list includes unusual household or garden equipment.

Choose DeWalt if you want one broad system that can handle serious DIY and construction. Choose Milwaukee if your work centers on professional trades, automotive repair, plumbing, or electrical service. Choose Makita if ergonomics and refined day-to-day handling matter more than having the cheapest entry point.

Before buying, list the five tools you are most likely to need in the next three years. Search that exact list within each platform. A battery ecosystem with 300 tools is not useful if it lacks the one specialty tool you actually need—or if its batteries, charger, and replacements cost more than the work justifies.
