Ryobi ONE+ HP 18V Brushless 15 in. String Trimmer Kit (4.0 Ah)

Model number
PBLST01K

The Ryobi PBLST01K is the complete kit version of the ONE+ HP 18V brushless 15 in. string trimmer, bundled with a 4.0 Ah HIGH PERFORMANCE battery and 18V charger — everything needed to trim right out of the box. The brushless motor provides efficient, high-torque performance comparable to gas trimmers while operating at significantly lower noise levels as part of the Whisper Series lineup. The REEL EASY+ 3-in-1 bump feed head offers three operation modes — bump feed, fixed-line, and bladed — for adaptability across different lawn and landscape conditions. EXPAND-IT attachment compatibility further extends the tool into an edger, blower, cultivator, or other implements using separately sold EXPAND-IT accessories.

§ FAQ

What is included in the PBLST01K kit?

The PBLST01K includes the ONE+ HP 18V Brushless 15 in. String Trimmer, one REEL EASY+ 3-in-1 Bump Feed Head, one 18V 4.0 Ah HIGH PERFORMANCE battery, and one 18V charger. It is a complete out-of-the-box trimming solution requiring no additional purchases to operate.

How much runtime does the 4.0 Ah battery provide?

Runtime varies depending on grass thickness, speed setting, and terrain. The 4.0 Ah HIGH PERFORMANCE battery is designed for extended sessions, with Ryobi typically rating it for 40+ minutes of trimming under normal conditions. For larger properties or heavier growth, upgrading to a 6.0 Ah or 9.0 Ah ONE+ battery (sold separately) will extend runtime further.

Is the included battery compatible with other Ryobi 18V ONE+ tools?

Yes. The 4.0 Ah 18V HIGH PERFORMANCE battery included in the PBLST01K is fully compatible with all Ryobi 18V ONE+ tools — the platform encompasses 300+ tools. You can use this battery interchangeably across drills, saws, blowers, and other ONE+ tools you may own.

What is the difference between the PBLST01K and the PBLST01B?

The PBLST01K is the complete kit that includes a 4.0 Ah HIGH PERFORMANCE battery and 18V charger in addition to the trimmer. The PBLST01B is the bare tool only — no battery or charger included. If you already own Ryobi 18V ONE+ batteries and a compatible charger, the PBLST01B is typically the more cost-effective choice.

Can the PBLST01K accept EXPAND-IT attachments?

Yes. The PBLST01K is EXPAND-IT attachment capable, allowing you to swap the trimmer head for compatible EXPAND-IT attachments such as an edger, cultivator, blower, or pole saw — all sold separately. This effectively turns the trimmer into a multi-tool outdoor power system.
