AA Digital Air Compressor

Product Information

However, most manufacturers use the 13-inch tyre as a measure of inflation speed, so we’ll forgive Halfords that. In reality, we found that the Halfords Rapid Digital Tyre Inflator could take a 17-inch wheel from 22psi to 32psi — a range that you’re unlikely to need day-to-day if you’re diligent about keeping your tyres in good condition — in 1 minute and 36 seconds. You feel as if, when you turn it on, it'll measure the amount of radiation in the atmosphere, not air pressure. It doesn’t look quite as snazzy as some of the others, thanks to the fact that it’s adorned in a cheap-looking silver plastic, but after all, you’re squatting on the ground with grease on your hands — elegance is already out of the window. It'll give you a figure in pounds per square inch (PSI) or BAR pressure. BAR is the metric unit of atmospheric pressure equal to 14.50 pounds per square inch.

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. It has a 3000mm (9.85 Ft) power cord and 600mm (1.97 Ft) air hose long enough to reach each tyre comfortably. Suitable for motorhomes, trailers and 4x4s, it makes a great option for multi-vehicle households and could save you quite a bit of money in fuel consumption over the years. It also comes in a handy carry bag and various valve adaptors, making it easy to transfer from one vehicle to another.We only ship to parts of the US, states include:California,Florida, Georgia, Illinois, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Texas, Virginia, Washington, Alabama, Arizona, Colorado, Iowa, Idaho, Kansas, Massachusetts, Maine, Missouri, Mississippi, Montana, North Dakota, New Mexico, Oklahoma, Oregon, South Carolina, Tennessee, Wisconsin You also get a much longer air hose, long enough to reach the top of the wheel if that’s where the valve is positioned when you park up. The dimensions of the AA5502 are 197 x 67 x 159mm and it weighs a mere 800g which means it’s lightweight and easy to store, perfect for keeping in your car’s boot. It can inflate a tyre in 3-5 minutes depending on size. Featuring an impressive LED light, it allows you to work with it in the darkness to avoid any potential dangers during operation.

There’s a clear digital display for the current PSI and also a mode switch to toggle between different units of measurement(bar, Kpa, psi, Kg/cm 2). It will automatically turn off when reaching the pressure value you preset. Size is probably the most important thing. The smallest inflators are around 20 x 20cm, so you can leave them in your car without losing too much luggage space. The best don’t skimp on the length of the power lead and air hose, which makes it easier to reach all four valves. Most can be preset to stop inflating when your tyre reaches the correct pressure. MOT Test– Your car could fail an MOT test if any of your tyres are under inflated, or have signs of uneven wear due to incorrect inflation. How Do I Find The Correct Tyre Pressures For My Car? Its colour scheme also has practical benefits, with bright yellow buttons that are easy to see in the dark. If you want to be equipped for every flat tyre eventuality, the VonHaus Cordless Tyre Inflator has you covered. It will run for up to ten minutes from the supplied 1.5A lithium-ion battery, but if you forget to charge it you can always switch to the bundled 12V adaptor, which comes with an unusually generous 3.5m cable. It has a small, but still readable, digital pressure meter. And you can just set your desired pressure, pull the trigger and let it go to work: it will stop when it reaches the right level.
