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. The Sealey MAC01 smoothly adds air to a flat tyre in an excellent time – but it's let down by its lever-type valve which feels primitive when compared to other inflators in this test. For the price score, it seems pretty obvious, but we’re basing the score on the price of the product against competitor products or even alternatives from the same brand. For example if we find another Ring product at a cheaper price than Ring RCT6000 Cordless Digital Tyre Inflator, but we feel they’re of similar quality, we’ll score the cheaper product higher. Ring RCT6000 Cordless Digital Tyre Inflator review score

After much research I decided on this, having had several other types that either didn't work well, or didn't last. This is very easy to use, powerful and is very well made. 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 extra convenience of being cordless adds to the cost, but for me a price well worth paying. After much research I decided on this, having had several other types that either didn't work well, or didn't last. This is very easy to use, powerful and is very well made. But while its portable nature and trigger style are perfect for squeezing in the odd PSI or two, this model's rather slow inflation speed and short (15cm) air hose make longer pumping jobs tedious. Finally we tried it on a few flat footballs and a basketball, using the attachment which cleverly slots in the base. Again it was simple to use and fast to inflate - a handy thing to have for when the kids decide they want to play football there and then. Over the time we've used it, we found it has kept its charge well, even when sat in the boot of the car for a few months.Some units are also equipped with an Auto-stop function, where you simply dial the target pressure into the inflator and it pumps out air until that pressure is reached. Simple. Most tyre inflators also feature screwed valve couplings which are faster and more effective than the old-fashioned lever coupling, making it even easier to add an accurate amount of air.

RTC600 Digital Tyre Inflator with auto stop. Comes with programmable digital gauge that automatically stops at the set pressure and remembers the information for future use.Here's a great concept: an inflator that’s cordless for maximum convenience but can also be connected to a 12-volt supply so it can continue pumping if the battery drains down. Wolf’s Glovebox Genie is definitely the best all-rounder for the money thanks to its solid inflation time and reasonable price. It may be slower than some tyre inflators ranked lower in this test, but it's only 25 secs slower than the brisk result set by the Sealey MAC01. Powered tyre inflators are an essential piece of maintenance equipment for any driver, helping car owners inflate or deflate the tyres on their car with ease. 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. This leftfield unit from Sealey gets the bulk of the basics right – but often in an odd way. For instance, the generous 5m power lead means the inflator can always be positioned right by the wheel, making its 2m coiled air hose a little excessive.
