Key Takeaways
- The Ryobi R18I-0 is a dual-function cordless inflator that delivers up to 150 PSI, with a digital pressure readout and automatic shut-off that halts inflation once your preset pressure is reached.
- The R18I-0 is sold body-only at around £58.49 to £79.95, so the battery and charger are not included, and first-time buyers without a Ryobi ONE+ 18V battery face a much higher true cost of ownership once those extras are added.
- The best all-round alternative is the Ordiniq AutoPump, which delivers the same 150 PSI as the Ryobi without any ecosystem lock-in, because its 3900mAh battery is built in and ready to use out of the box. The Makita DMP181Z reaches 161 PSI but carries the same bare-tool limitation as the Ryobi.
- The Ordiniq AutoPump is priced at £49.99 with free UK delivery, a 90-day money-back guarantee, a built-in LED and SOS light, and a universal adapter kit, making it the most accessible choice for UK drivers who simply want to inflate a tyre without buying into a power-tool ecosystem.
Which Cordless Tyre Inflator Is Right For You
If you want a cordless tyre inflator that works straight out of the box, the Ordiniq AutoPump is the most practical pick, while the Ryobi R18I-0 is a strong option for anyone already invested in the Ryobi ONE+ 18V platform. Both reach 150 PSI and include auto shut-off, but the Ryobi is sold as a bare tool, so the battery and charger are an extra spend. For drivers who just want to inflate a tyre without buying into an ecosystem, that difference decides the purchase.
The Ryobi R18I-0 is better suited to home improvement enthusiasts who already own Ryobi tools because it fits into the ecosystem. For people exploring Ryobi inflators for the first time, the Ordiniq AutoPump and Makita DMP181Z may be better alternatives.

Core Features of the Ryobi R18I-0
The Ryobi R18I-0 Cordless Tyre Inflator has a maximum pressure of 150 PSI (image source: Amazon UK).
Dual Inflation & Deflation Modes
The R18I-0 inflates and deflates, too. This is useful for quickly packing away air mattresses, inflatable kayaks, or camping gear without having to manually squeeze the air out.
Digital Pressure Readout & Auto Shut-Off
One of the most useful features is the digital pressure gauge, combined with the auto-shutoff function. You set your target pressure, and the inflator stops automatically once it's reached. This completely removes the risk of over-inflating a tyre, which can be a safety hazard.
Maximum Pressure: 150 PSI (10.34 Bar)
At 150 PSI (10.34 bar), the R18I-0 delivers enough pressure to handle standard car tyres with ease. Most passenger car tyres sit between 30–35 PSI, so this inflator has more than enough headroom. It also covers road bikes, which typically require 80–130 PSI.
Weight, Noise Level, & Hose Length
At approximately 1.7 kg (including battery), the R18I-0 is lightweight and portable. The R18I-0 has a rated sound pressure level of 75 dB(A), which is moderately quiet for an inflator, though consideration should be given when using it early in a residential area. Additionally, the 711mm hose is a practical length that reaches all four corners of most vehicles without needing to reposition the unit.
Ryobi R18I-0 Price
The Ryobi R18I-0 is sold as a body-only unit, meaning no battery or charger is included. This is standard practice across the Ryobi ONE+ range and works in your favour if you already own 18V Ryobi batteries from other tools. The body-only price ranges from £58.49–£79.95, depending on the retailer, with regional pricing variations.
If you don't already own a compatible Ryobi 18V battery, factor in the additional cost of a battery and charger kit before assuming this is the most cost-effective option. For first-time buyers entering the Ryobi ecosystem purely for this inflator, the total investment climbs considerably, which is why comparing alternatives makes sense.
Alternatives Worth Considering
The cordless tyre inflator market has grown significantly, and the Ryobi R18I-0 isn't the only strong contender on the shelf. Here are two alternatives that consistently come up alongside the Ryobi R18I-0 in any honest comparison.
1. Ordiniq AutoPump (Best Alternative)
The Ordiniq AutoPump has a powerful built-in rechargeable battery.
If you are looking for the best alternative to the Ryobi R18I-0, the Ordiniq AutoPump is the clear upgrade, because it outperforms both the Ryobi and every other option in its price bracket.
Where the Ryobi requires you to already own or separately purchase an 18V ONE+ battery and charger, our AutoPump arrives completely self-contained, ready to use straight out of the box.
It is powered by a built-in 3900mAh rechargeable battery that can be charged via USB-C, a UK plug adapter, or a 12V car lead, offering charging flexibility that the Ryobi, locked into its proprietary battery ecosystem, cannot match.
On performance, the AutoPump is rated up to 150 PSI and features a smart auto-shutoff that stops inflation the moment it reaches your preset pressure, eliminating the risk of overinflation. This makes it just as capable as the Ryobi for car tyres, bicycles, and motorcycles. Plus, its built-in needle adapter means it handles sports balls and inflatables too, covering every use case in a single device.
Its compact design at just 7.87 x 5.08 x 15.75 cm means it fits easily in a glove compartment, kit bag, or car boot, making it a far more practical everyday carry than the bulkier, tool-style form factor of the Ryobi.
Our AutoPump is priced at £49.99 (reduced from £116.35), with free UK delivery on every order. Unlike the Ryobi, which is sold as a bare tool with no battery, every AutoPump purchase comes backed by a 90-day money-back guarantee.
2. Makita DMP181Z Cordless Inflator
The Makita DMP181Z is a professional-grade cordless inflator aimed at tradespeople and serious DIYers who are already invested in the Makita 18V LXT battery ecosystem. It delivers a maximum air pressure of 161 PSI and an airflow of 22 litres per minute at 200 kPa.
This cordless inflator features three inflation modes, a digital pressure gauge, an LED job light, and an auto-stop function that shuts the tool down once your preset target pressure is reached. The DMP181Z also includes overheating protection via a built-in thermostat, a memory function, and an air release button for correcting overinflation.
The main limitation of the DMP181Z is the same as that of the Ryobi. It is sold as a bare tool, meaning the battery and charger are not included in the purchase price. The body-only unit is priced at approximately £94.45, and once you factor in the cost of a compatible 18V LXT battery, the total investment climbs considerably higher.
For those without an existing Makita collection, this is a significant barrier, making the Ordiniq AutoPump, with its built-in battery, the far more accessible and cost-effective choice.

The Easier Way to Keep Your Tyres Inflated
The Ordiniq AutoPump comes with free tyre pressure monitoring caps.
The Ryobi R18I-0 is a capable tool for anyone already committed to the Ryobi ONE+ 18V platform, but the body-only pricing hides the real cost for first-time buyers who still need a battery and charger. The Ordiniq AutoPump removes that problem entirely with a built-in battery, the same 150 PSI output, and a smart preset function that stops inflation at your target pressure every time.
For UK drivers who want an inflator that is ready the moment it arrives, the Ordiniq AutoPump is priced at £49.99 with free delivery, a 90-day money-back guarantee, and a built-in LED and SOS light for roadside emergencies.

Frequently Asked Questions (FAQs)
What batteries are compatible with the Ryobi R18I-0?
The Ryobi R18I-0 is compatible with any Ryobi 18V ONE+ battery. This includes the full range of Ryobi ONE+ lithium-ion batteries, from compact 2.0Ah packs to high-capacity options of 8.0Ah and 12.0Ah for extended runtime. If you already own other Ryobi ONE+ tools, the batteries you use for those will work directly in the R18I-0 with no adaptor required.
Can the Ryobi R18I-0 inflate car tyres?
Yes. The Ryobi R18I-0 inflates standard passenger car tyres with no difficulty. Most car tyres require between 30 and 35 PSI, which sits well within the R18I-0's maximum output of 150 PSI (10.34 bar). It also works on van tyres, motorcycle tyres, and road bicycle tyres, which can require up to 130 PSI.
Does the Ryobi R18I-0 come with a battery?
No, the Ryobi R18I-0 is sold as a body-only unit, meaning no battery or charger is included. This adds to the overall cost, so it's worth calculating the full investment before comparing it to all-in-one alternatives like the Ordiniq AutoPump, which includes a battery and is ready to use straight out of the box.
Can the Ryobi R18I-0 deflate and inflate?
Yes. The R18I-0 includes a dedicated deflation function, which makes it far more useful than a basic inflator. This is particularly handy for quickly and completely collapsing air mattresses, inflatable camping gear, and paddling pools.
How does the Ordiniq AutoPump compare to the Ryobi R18I-0?
At Ordiniq, we designed the AutoPump to pull ahead on accessibility and total cost of ownership. Its built-in 3900mAh battery is already included, so there is no hidden cost to get it running. The AutoPump also features a bright white LED and a red SOS flashing light for emergencies, plus multiple nozzle attachments that extend its use beyond car tyres.
