The unit is small enough to keep in your boot and comes with its own case to keep the dirt out of your car. The 12v connector can be neatly wound away on a spindle, saving the normal tangle you get yourself into. The 3.5m lead isn’t perhaps as long as some on the market but can do the job of reaching the tyre furthest away from the in-car power supply.

Cordless tyre inflator, ideal for camping and road trips. The RTC6000 digital tyre inflator can inflate a tyre in just two minutes. Comes with air compressor setting for tyres, and air pump setting for air beds. Can inflate a single airbed in just two minutes. While there are plenty out there, one of the best is Halfords' rechargeable inflator, which features a max pressure of 120psi as well as an auto cut-off function. This comes with a variety of adapters, as there is the ability to pump up mattresses too, but that isn't something I'll do, as our kids will use it when they go camping this summer. Read less The inflator is easy to use, thanks to the flat design, large on/off button and valve cap storage. The deflation valve allows you to make small reductions in pressure. Much improved is the tyre valve connector which, unlike many others, is now sturdier. This new, bigger brass unit makes it much easier to connect to a tyre valve that’s all covered in road gunk because it’s big enough for you to grip properly. It’s also much easier to attach to tyres with awkwardly placed valves. As always, there’s a deflator valve if you need to let some of the air out.Despite its smaller size, the Ring performed well, inflating the tyre faster than some of the larger models in this test. The Ring also retains a leisure inflator/deflator and is fitted with a Deflate button. We were also a fan of the foolproof knob and display set-up, and the smart carrying bag. The inflator sits on four rubber feet to prevent it scuttling around your driveway, while the air hose wraps snugly beneath the device. The same can’t be said for the 12V connector, though, which must be wrapped around your hand and cable tied before it can be reinserted into the inflator. What I did find though, was that having set this and the number being reached, it continued to pump. Not sure why, but maybe to allow for when you remove the tube from the valve, albeit the leakage was so minimal, to be nothing!

The RTC1000 Rapid Digital Tyre Inflator makes tyre maintenance fast and easy. The RTC1000 inflates a 13" tyre in just 2 minutes. It comes with three adaptors, LED light storage case, spare valve caps and latex gloves.Comes with LED light to make night time inflation easier and safer. Also comes with 10 piece adaptor set for use with tyres, bicycle tyres, motorcycle tyres, balls, airbeds and other small inflatables. Includes case and storage for adaptors. Its colour scheme also has practical benefits, with bright yellow buttons that are easy to see in the dark. The Ring RTC2000 Cordless Handheld Tyre Inflator is a small rechargeable tyre inflator that's designed for topping up car tyres and inflating bicycle tyres, footballs (and the like) and even inflatables. It's light in weight (at roughly 500g) and comes with a two piece adaptor kit for sports equipment and Presta bike valves. There's an LED light and it also acts as a powerbank function if need be. This is an excellent and lightweight automatic pump. It is powered by a lithium-ion battery, so the mains lead is only there to charge the battery and cannot be plugged in during use. I thought I was buying a mains powered pump so was disappointed, until I realised that it has sufficient power to inflate four tyres (as long as they are not completely flat) up to required pressure, without the hassle of trailing wires. Halfords claims that the inflator can pump an R13 tyre (13 inches in diameter) from flat to 30psi in three minutes, thanks to a flow rate of between 28 and 30 litres per minute. While that might sound good, there are very few modern cars that use R13s — even the tiny Smart ForTwo uses 15-inch tyres.

You feel as if, when you turn it on, it'll measure the amount of radiation in the atmosphere, not air pressure. Comes complete with three-piece adaptor kit for balls, bike tyres and other inflatables. Also includes handy storage case. Given most people are used to tyre inflators being the size of a kids lunchbox with wires and cables, this small handlheld design might come as a surprise. It's about the size of a standard 50cl bottle of water and not much different in weight either. To charge it up took about three hours when it first arrived and since then we've been charging it up between uses.The Halfords model was one of the most compact devices we tested, meaning that it doesn’t take up precious boot space. However, it doesn’t come with a case, like the admittedly pricier Ring RTC1000, meaning that it’s vulnerable to getting scuffed by other things that you put into your boot. Add air until you’ve reached the correct pressure, detach the inflator, and replace the valve caps. How do under inflated-tyres affect your vehicle? Extra long 70cm air hose with easy access storage compartment specifically designed to reduce kinks You’ll first need to remove the valve caps (remember — righty tighty, lefty loosey); then attach your tyre inflator or pressure gauge, and compare the number that appears to the recommended pressure for your tyres — more often than not displayed in psi, and usually somewhere between 30 and 35.

Like most of the other inflators, it comes with three attachments so that you can inflate footballs, bouncy castles and whatever else your heart desires. The on/off switch is large, but temperamental and does not always stay on meaning that you have to manually hold the switch down while the pump is working. This may be a fault with my pump. As mentioned before, driving on under-inflated tyres mean that there is more friction between the tyre and the road. To get the quality score, we’re looking at a number of factors, but typically we’re studying the brand of the product, the warranty included and basing it on what customers have to say about the quality. In the box you get the inflator as well as a carrying bag and a bottle cage attachment so you can carry it on your bike. The unit is charged via a standard USB cable that's supplied.Also the plug you plug in to charge the pump feels rather flimsy. Your frightened of misalignment when you plug it in or pressing/pushing it in too hard. Like the Ring RTC1000, its designers have also thought of where to store your valve caps when you’re inflating, and have included a little stand. Ideal for inflating car tyres or sports equipment, The Ryobi One has an easy-view pressure gauge and a powerful motor for rapid inflation. It allows up to 150psi of pressure and includes two high pressure nozzles and a sports and ball needle if required. However, it completed our 22psi - 32psi test in comfortably under two minutes (around 1 minute and 50 seconds), meaning that it doesn’t make inflating your tyres into too much more of a chore than it already is. Again, it’s not the most attractive machine in the world, but again, this is tyre inflation, not Paris Fashion Week. The analogue scale goes from 0psi-100psi, with around a centimetre between each increment of 10psi. That means that the difference between, say, 30psi and 32psi is just a couple of millimetres, making it a tad difficult to know exactly how much pressure you’re putting into your tyres — an issue exacerbated by the fact that the machine moves around a lot as it inflates.
