Powarobor 2-Pack 5.5Ah 18V Lithium-Ion Battery & P117 Charger Combo for Ryobi ONE+
Product description
If your Ryobi 18V ONE+ tools are running on tired batteries, this Powarobor 2-Pack is aimed at the practical fix: two lithium‑ion 5.5Ah packs plus a P117 charger in one bundle. On paper, it’s built for everyday replacements, with protection features and a simple way to monitor charge via built-in LED indicators.
That said, it’s not quite a “universal” buy for every Ryobi setup. You’ll want to match the battery/charger family and check your current battery model so the combo fits your existing tools.
The essentials
This bundle includes: - A 2-pack of 18V lithium-ion batteries rated at 5.5Ah (5,500mAh) - A P117 charger for 18V battery packs
The intent is pretty clear: replace old or damaged packs, keep a spare on hand, and reduce downtime while you’re working. With two batteries included, you can rotate them through jobs rather than waiting for a single pack to charge.
What to know about compatibility
The listing states compatibility with Ryobi 18V cordless tools and provides a set of compatible battery references. It also says the charger is compatible with Ryobi 18V 14.4V / 12V / 9.6V Li-ion and Ni-Mh / Ni-Cd battery types.
In other words, it’s designed for Ryobi ONE+ style ecosystems. Still, you should double-check that your existing battery fits within the named compatibility group (for example, several P-series and specific RB-series references are mentioned) before committing.
What you’ll notice day to day
On use, the headline features are the protection system and the LED indicators. The battery is described as having built-in safeguards against overcharging, over-discharging, overheating and short circuits. That’s the kind of “quiet” safety you really appreciate when you’re using tools frequently—especially if batteries sit in storage between jobs.
The 4 smart LED indicator lights are also handy. The guidance is simple: if the LED display shows only one grid, you’re expected to charge it in time, rather than pushing the battery until it runs flat.
One more practical point: the batteries are described as having no memory effect, which means you can top them up or partially discharge them without the same kind of capacity loss some older battery types could suffer from.
Key specifications (quick technical read)

Where it shines (and where it may not)
If you want a straightforward way to extend the runtime of your Ryobi 18V cordless toolkit, this combo makes sense. Two batteries at 5.5Ah each can be particularly useful for weekend jobs—think string trimmer sessions, a mower task, or yard clean-up—where you don’t want to stop just because one pack is empty.
Worth considering if you’re currently using a Ryobi 18V system and simply need replacements plus a charger, rather than experimenting with an unknown third-party setup.
It might not be the best match if you’re chasing maximum “no compromises” performance from a higher-end battery line, or if your current batteries don’t fall within the compatibility references listed. Also, if you rarely use your tools, buying two packs could be more than you need.
How to get the most from it
A simple routine goes a long way. Keep the spare battery ready so you can swap mid-job, and pay attention to the LED indicator grids rather than running it down to the point it’s clearly struggling. The listing also hints that you shouldn’t exhaust the battery—so charging earlier can help you keep usable performance more consistently.
Mini example: if you’re mowing or edging and you notice the battery has only one LED grid showing, it’s a good moment to switch to the second pack and let the first one recover on the P117 charger.
Should you buy it?
Buy it if you already own Ryobi 18V cordless tools, need replacement batteries, and want a 2-pack plus a compatible charger to reduce downtime. It’s also a sensible pick if you like the idea of battery protection features and quick charge monitoring via built-in LEDs.
Skip it (or at least re-check compatibility) if your existing Ryobi battery model isn’t within the references mentioned, or if you only need one replacement battery and the idea of holding two packs doesn’t add much value for your usage.
