RYOBI ONE+ is the battery platform. ONE+ HP is a performance tier inside that platform. Both use the same 18-volt ONE+ battery system, which means an HP tool and a standard ONE+ tool are part of one ecosystem, not two competing ones. According to RYOBI's own pages, the HP line combines high-performance brushless motors, advanced electronics and high-performance lithium technology to deliver more power, runtime and durability. A standard ONE+ tool is the broader line that RYOBI has built over decades.
So the practical difference is the tool, not the battery plug. If you already own ONE+ batteries, you can generally shop HP tools without starting over. This guide explains what RYOBI says about each tier, and shows how the specifications differ across example tools. Everything here is researched from specifications; nobody here has used these tools.
What ONE+ Means
ONE+ is RYOBI's 18V cordless platform. RYOBI's ONE+ collection page describes it as a system that has stayed compatible across generations, starting with a Ni-Cd cordless drill in 1996, with lithium-ion arriving in 2007 while remaining fully compatible with the platform. It says the system now includes over 300 compatible products. RYOBI's ONE+ battery page says its batteries are compatible with any RYOBI 18V ONE+ product.
That long backward compatibility is the main reason people choose ONE+. A drill, a saw, an inflator and a string trimmer can all share the same batteries. The tools in this article all work with RYOBI 18V ONE+ batteries and not with other brands.
What HP Means
RYOBI's ONE+ collection page presents HP as the 2018 upgrade to the platform. It describes the technology as high-performance brushless motors, advanced electronics, and high-performance lithium technology. RYOBI uses "HP" as a badge on the product name, for example "18V ONE+ HP Brushless 7-1/4" Circular Saw", and some products pair the badge with the label "High-Performance".
The key point is that HP is a tool-side feature set. A brushless motor uses electronics rather than carbon brushes to switch the motor, which generally means less friction and wear and better efficiency. The advanced electronics in HP tools manage that motor and protect the battery. HP is not a separate voltage or a separate battery connector.
Where the Specifications Differ
The cleanest way to see the difference is to compare example tools with the figures RYOBI publishes.
| Product | Tier | Figures from RYOBI |
|---|---|---|
| RYOBI 18V ONE+ 1/2" Drill/Driver Kit | Standard ONE+ | Up to 515 in-lbs of torque; 2-speed gearbox, 0-450 and 0-1,750 RPM; 1/2" keyless ratcheting chuck |
| RYOBI 18V ONE+ HP Brushless 4-Mode 1/4" Impact Driver | HP | Up to 2,300 in-lbs of torque; 0-3,400 RPM; 0-4,200 IPM; three speeds plus an assist mode |
| RYOBI 18V ONE+ HP Brushless 7-1/4" Circular Saw | HP | 7-1/4" blade; up to 2-9/16" depth at 0 degrees; up to 370 cuts per charge as claimed by RYOBI |
| RYOBI 18V ONE+ HP Brushless 1/2" Drill/Driver | HP | Brushless, bare tool |
These tools are different classes, so the table is not a head-to-head. A drill/driver, an impact driver and a saw produce different numbers by design. What the table shows is the kind of specifications the HP line publishes. The impact driver, for example, lists a four-mode setup with three speeds plus an assist mode, and an impact rate in impacts per minute. The standard drill/driver kit publishes a torque figure and a two-speed gearbox.
The fair summary is that RYOBI positions HP as a step up in power and runtime from the standard ONE+ line, and that you should compare the specific model's figures on its own page.
Brushless vs Brushed
Many HP tools are brushless. A brushed motor uses carbon brushes that rub against a spinning part to deliver current; those brushes wear down and create friction and heat. A brushless motor replaces them with electronics, which usually means better efficiency, longer motor life and more run time from the same battery. The RYOBI 18V ONE+ HP Brushless 1/2" Drill/Driver, the RYOBI 18V ONE+ HP Brushless 4-Mode 1/4" Impact Driver and the RYOBI 18V ONE+ HP Brushless 7-1/4" Circular Saw are all brushless. Check the motor type on a standard-line tool such as the RYOBI 18V ONE+ 1/2" Drill/Driver Kit before you assume.
Batteries: Do You Need HP Batteries?
This is the question people ask most, and the honest answer is that RYOBI does not make a firm statement. The ONE+ collection page says the platform has stayed compatible across generations. The 4Ah battery page says its batteries are compatible with any RYOBI 18V ONE+ product and describes longer runtime and more power. The HP circular saw and impact driver pages do not name a required battery.
That means you can generally expect HP tools to accept the ONE+ batteries you already own. What the pages do not tell you is how a tool performs on a small battery versus a large one. RYOBI describes its HP technology as including high-performance lithium technology, and in 2024 it added Edge batteries, which it says use tabless lithium cells for more power and longer battery life. For a demanding tool such as a circular saw, a larger-capacity pack is the sensible choice, because the "up to 370 cuts per charge" figure RYOBI quotes depends on the battery and the material being cut. Check the tool page for the battery it recommends.
The RYOBI 18V ONE+ 4Ah Battery is a 4.0 Ah lithium pack for ONE+ tools. It is a mid-size option that works across the platform.
Which Tier Fits Which Buyer
Home and light projects. A standard ONE+ drill/driver kit is a reasonable fit for hanging shelves, assembling furniture and small repairs. The RYOBI 18V ONE+ 1/2" Drill/Driver Kit is sold with one 1.5Ah battery and a charger, which is a complete starting set for this kind of use.
Frequent or heavier work. If you drive long screws, cut lumber or work for hours, the HP line is designed for more demanding use. The RYOBI 18V ONE+ HP Brushless 4-Mode 1/4" Impact Driver lists up to 2,300 in-lbs of torque and four modes, which suits fastening work where you want control over the speed.
Cutting. A circular saw is among the most battery-hungry tools in a home shop. The RYOBI 18V ONE+ HP Brushless 7-1/4" Circular Saw is a bare 7-1/4-inch saw in the HP line. RYOBI's page lists depth of cut and bevel capacity, with a bevel range of 0 to 56 degrees and detents at the common angles, and says it makes up to 370 cuts per charge. That claim comes from the manufacturer, and results will vary with the battery and the material.
Adding to a platform you already own. If you have ONE+ batteries, the bare RYOBI 18V ONE+ HP Brushless 1/2" Drill/Driver is the add-on version of the HP drill/driver. It is sold without battery or charger.
Things to Check on the Product Page
- Model number. RYOBI sells several similar tools with similar names, and an older generation can sit beside the current one. Use the model number to match the tool you want.
- What is in the box. Many HP tools are sold as tool only, while kits add batteries and a charger. Our guide on tool only vs kit explains how to read that.
- Battery guidance. If a tool's page suggests a battery size, follow it.
- Warranty. Check RYOBI's warranty terms for the exact model before buying.
Frequently Asked Questions
Can I use my old ONE+ batteries on an HP tool?
RYOBI describes ONE+ as a platform that has stayed compatible across generations, and its 4Ah battery page says its batteries work with any RYOBI 18V ONE+ product. The HP product pages do not name a required battery. Confirm on the specific tool page.
Is HP a different voltage?
No. The HP tools covered here are 18V ONE+ tools.
Are all ONE+ tools brushless?
Not necessarily. The HP tools covered here are brushless, but standard-line tools vary. Check each product page.
Is an HP tool worth it for occasional use?
It depends on the task. RYOBI positions HP for more power and runtime. For occasional light jobs a standard tool may be enough. Compare the figures for the exact tool.
