Ryobi vs Einhell brush cutters: ONE+ vs Power X-Change

Ryobi and Einhell compete for the same buyer: someone who wants a capable cordless brush cutter without paying pro-brand prices, and who’ll likely add more battery tools to the shed afterwards. The split between them isn’t about which cuts grass better on any given day — it’s about how each brand structures its battery system, and what that means for your wallet and your toolbox over time.

At a glance

Attribute	Ryobi (ONE+ / 36V MAX Power)	Einhell (Power X-Change)
Battery structure	Two separate families: 18V ONE+ and 36V MAX Power	One family: 18V packs, with 36V tools running two in series
Brush cutter platform	36V MAX Power (e.g. RBC36X26B)	Agillo series, spanning 18V and 36V models
Blade included as standard	Often yes on 36V models — Ryobi’s edge	Line-focused by default; blade sometimes a separate purchase
Cross-tool compatibility	Only within each voltage family, not across them	Full — every Power X-Change tool shares the same 18V packs
Range breadth	Very large; one of the biggest cordless ranges overall	Large and growing, slightly narrower in places
Retail availability	Extremely widespread, easy to compare pricing	Widely stocked, marginally less ubiquitous
Entry price	Value, but a second battery family adds cost long-term	Usually the cheaper way in, especially for first-time buyers
Best suited to	Buyers who want a scrub-ready cutter and don’t mind two battery types	Buyers who want one battery type for absolutely everything

Clear wins: Ryobi wins on out-of-the-box cutting versatility (blade included on many 36V models) and sheer range size; Einhell wins on simplicity and value, since every battery you buy works in every tool regardless of voltage.

The core difference: one voltage family or two

This is the single most important thing to understand before comparing anything else. Ryobi’s 18V ONE+ system is genuinely huge, but it tops out at a voltage that doesn’t suit a brush cutter needing sustained cutting torque. So Ryobi’s serious brush cutters live on a distinct 36V MAX Power platform, with different batteries and a different charger. Own both and you’re maintaining two separate charging ecosystems.

Einhell took a different route with Power X-Change: every tool, whether it needs 18V or 36V, runs on the same 18V battery — the 36V machines simply take two packs at once, wired in series inside the tool. That means an Einhell owner never has to ask “which battery family does this need?” The answer is always the same one.

Neither approach is wrong, but Einhell’s is structurally simpler, and that simplicity compounds every time you buy another cordless tool.

Cutting power and what ships in the box

For the brush cutter itself, Ryobi’s 36V models such as the RBC36X26B have a strong habit of shipping with a hardened-steel blade attachment alongside the line head, so the machine is ready for both grass and modest scrub the day it arrives. Einhell’s Agillo brush cutters are typically set up as line trimmers first; if you want to cut through brambles or woody growth, check the specific model, since a blade option isn’t always bundled.

If your land is tidy lawn and edges, this difference barely registers — a line head handles it. If you know you’ll meet the occasional patch of tough weeds or light scrub, Ryobi’s tendency to include a blade removes one extra purchase and one extra decision.

Range breadth and long-term ecosystem value

Ryobi’s combined ONE+ and 36V MAX Power catalogue is enormous, spanning power tools, garden equipment and even outdoor living gadgets, and it’s stocked about as widely as any cordless brand on the market. The catch is that breadth is split across two voltage tiers, so building a full cordless shed on Ryobi often means owning chargers and batteries for both. Einhell’s Power X-Change range is smaller in absolute tool count, but every single tool in it draws from the same battery pool, which keeps your total spend on “spare” batteries and chargers lower as the collection grows.

For a buyer starting completely from scratch, that difference matters more than brush cutter specs alone. Buying one 18V Einhell battery effectively future-proofs you for every Power X-Change tool you might add later, including the 36V ones. Buying into Ryobi means deciding upfront whether you want the light 18V tools, the heavier 36V garden tools, or both — because “both” is two ecosystems, not one.

Full range detail lives on the Ryobi brand page and the Einhell brand page.

Choose Ryobi if…

• You want a brush cutter likely to arrive blade-equipped and ready for light scrub, not just grass
• You’re happy running two battery families (18V ONE+ for light tools, 36V MAX Power for heavier garden kit)
• You want the largest possible range of cordless tools to choose from, with easy retail comparison

Choose Einhell if…

• You want every battery you own to work in every tool, at 18V or 36V, with no exceptions
• Lowest realistic entry cost and long-term simplicity matter more than maximum range size
• You’re building a cordless tool set-up from zero and don’t want to commit to two separate systems

Which should you buy?

If you already know you want a brush cutter that handles light scrub straight out of the box, and you don’t mind Ryobi’s two-tier battery structure, its 36V MAX Power range is the more capable starting point for cutting alone. If you’d rather never think about which battery family a new tool needs — and you’re building your cordless collection from scratch — Einhell’s Power X-Change is the tidier, usually cheaper way in, with the trade-off that a blade for scrub work may be a separate purchase on some models. Existing tool ownership should settle it either way: match the brush cutter to the batteries already in your shed before you look at anything else.
