Building an outdoor-tool lineup on one battery platform can save money, but the brand name alone won’t tell you which costs less. Kobalt and Ryobi both sell cordless mowers, trimmers, blowers and chainsaws at several price points. Your total depends on which tools you need, whether a kit includes useful batteries and how much performance your yard demands.
For a fair comparison, price the tools you’ll actually buy—not every tool in either catalog. A homeowner who needs a trimmer and blower may spend far less than someone adding a mower, hedge trimmer and chainsaw. Prices also move with promotions, so treat the figures below as typical retail ranges rather than fixed quotes.
Two battery platforms, different strengths
Ryobi’s 18V ONE+ system covers a broad range of lighter outdoor tools, while its 40V line is aimed at higher-demand equipment such as mowers and larger blowers. Batteries do not interchange between those voltage families. Kobalt’s outdoor lineup is centered on 24V and 40V tools; those batteries are not interchangeable with each other, either.
That matters when estimating the cost to build. A 40V mower won’t be powered by the 18V battery you already own, and buying a mower kit may put you into a second battery system. Before shopping, write down the voltage printed on your existing batteries and check the tool listing carefully.
Typical costs for a small yard lineup
The table gives broad street-price ranges for common homeowner equipment. A “bare tool” is sold without a battery or charger; kits typically include both. Retail prices vary by capacity, sales and included accessories, and mower prices vary substantially with deck size and whether the mower is self-propelled.
| Equipment | Kobalt, typical range | Ryobi, typical range | What to check |
|---|---|---|---|
| String trimmer | $100–$180 kit | $100–$200 kit | Cutting width, line feed and battery size |
| Leaf blower | $100–$220 kit | $100–$250 kit | Air volume, runtime and whether it is a high-output model |
| Push mower | $300–$600 kit | $300–$700 kit | Deck width, battery count and yard-size claims |
| Hedge trimmer | $100–$200 kit | $100–$220 kit | Blade length and included battery |
| Chainsaw | $150–$300 kit | $150–$350 kit | Bar length, chain size and intended cutting load |
Those ranges overlap. Neither brand is consistently cheaper across every category, and a discounted kit can beat a bare-tool price once you account for the battery and charger. Compare the exact contents: a kit with a small battery may cost less but run a mower or blower for noticeably less time than one with a larger pack.
Build the basket before choosing
For a small property, start with a trimmer and blower. Buying two kits can leave you with duplicate chargers and more batteries than you need. If the tools share a platform, a kit for one tool and a bare tool for the other may be the lower-cost combination—provided the battery has enough capacity for the second job.
For example, suppose the trimmer kit costs $150 and the bare blower costs $120. That $270 total is cheaper than buying two $150 kits, but only if the included battery can handle the blower’s workload. If it runs flat before you finish clearing the driveway, the apparent $30 saving may mean buying another pack. Check the battery’s amp-hour rating and look for runtime guidance, but remember that heavy grass, wet leaves and sustained high speed shorten runtime.
Use current listings to compare a Kobalt trimmer kit with a Ryobi 40V trimmer kit, making sure both listings include comparable batteries. Search results can mix bare tools, older versions and different battery capacities, so verify the product details before comparing prices.
Mowers are the budget swing
A mower is usually the biggest expense in an outdoor lineup. A basic push mower may suit a small, mostly level lawn; a wider self-propelled mower can make sense on a larger yard or slopes, but it raises the purchase price and draws more power. Battery runtime also depends on grass height and thickness. Letting grass grow long between cuts can turn a comfortable one-charge job into a battery swap.
Compare deck width, included battery capacity and the manufacturer’s stated cutting area—not just the mower’s headline price. If your lawn is near the claimed coverage limit, budget for a second battery or consider a corded or gas mower instead. A corded mower can cost less if an outlet and manageable cord path are available; a gas mower may be more practical for a large area, though it adds fuel and maintenance costs.
For a mower purchase, compare a Kobalt 40V push mower with a Ryobi 40V push mower. Match deck size and battery configuration as closely as possible; a cheaper mower package may include fewer or smaller batteries.
Where the savings can disappear
Battery replacement is the main long-term cost risk. A high-demand tool can drain a small pack quickly, and batteries lose capacity with age and heat. Avoid leaving packs in a hot shed or vehicle, and store them according to the manufacturer’s instructions. If a platform’s batteries are frequently on sale, that may improve its long-term value—but don’t count on a future discount to make today’s purchase work.
Also check local availability. A lower-priced tool is less useful if a damaged charger or replacement battery is hard to find nearby. Warranty terms, service access and the return window are worth checking before buying, especially for a mower. Keep the receipt and test the equipment during the return period on the kind of work you expect it to do.
Choose by your existing batteries and workload
If you already own compatible batteries, the cheaper build is usually the platform you have—not necessarily the brand with the lowest standalone tool price. For a new lineup, compare matched kits and add the cost of any extra batteries your yard requires. Ryobi’s 18V and 40V options provide distinct routes for light and heavier jobs; Kobalt’s 24V and 40V tools likewise require you to choose the right battery family up front.
For occasional trimming and light leaf cleanup, the least expensive kit that includes a suitable battery is often enough. For a mower, large yard or frequent heavy use, prioritize runtime and battery capacity over a small difference in shelf price. The cheaper platform is the one that finishes your jobs without forcing an unplanned battery purchase.
