I measured it at 34 seconds to inflate a 25mm tyre to 105psi; an SKS Rennkompressor is quicker at just 20 seconds, but is less convenient. He got the gig by phoning up the editor and telling him the magazine was rubbish and he could do better. The Makita 18v LXT Inflator offers higher maximum pressure than its previous models and stops inflating when the required air pressure level is reached. Only Downside is you have to keep your finger on the trigger until it turns itself off at the required pressure, but a small Downside to an otherwise brilliant pump. They say it doesn't drain the battery much, it does what you'd expect, and the batteries from Makita are always great.

As with cars though a bigger engine does not always translate to better performance so it is important to compare the specifications of tools at different voltages between different manufacturers. The Makita DMP180 18v LXT cordless inflator has a built-in motor that delivers up to 120psi, easily inflating car tyres, sporting equipment and used for many more applications. If it had a longer hose, a better Presta adapter and a switch that didn't need constant pressing, it'd be perfect. They mention that it's great for pumping the tyres up on the vehicles, it quickly inflates car t yre, and is quite capable of inflating te yrs over 100psi.They all have a little place to live in the body of the inflator, but you just know you're going to lose them sooner or later. Once that pressure is reached, the compressor stops, so you can't absent-mindedly over-inflate a tyre. The Makita DMP181 is a handy cordless inflator powered by any 18v LXT battery suitable for inflating tyres, boats and camping equipment, to name a few. Makita’s leading technology gives tool users unmatched performance and breadth of line, with innovation in motor and battery technology that is obliterating industry standards – and leaving old thinking behind.

Other features include a digital pressure gauge (with backlight), LED work light for easy operation in the dark, soft-grip ergonomic handle and adaptor holder. The Makita DMP180 18v LXT inflator has a built-in motor that delivers up to 120psi, easily inflating car tyres, sporting equipment and used for many more applications. The inbuilt pressure gauge readings are the same as their dedicated, and there are no problems with high pressures.The main switch is equipped with the Auto-off function to prevent accidental start-up during transportation, this not only protects the tools and other tools around it but it also prevents the battery from discharging quickly.

The maximum pressure it can reach is 120psi, which is enough for almost all bike applications except track racing. It's possibly a bit unreasonable to criticise a general-purpose device like this for its shortfalls as a cycling tool, but the adapters to inflate Presta valves, balls and other inflatables feel like afterthoughts.
