## Features

- Quick inflation. The RTC500 inflates a 13” tyre from 0psi to 35psi in just 3 minutes – making it quick to top up tyres.
- Auto stop for accuracy. The Auto stop takes the guesswork out of inflation. Simply set the pressure you need, press start, and the RTC500 will automatically stop once the pressure is reached.
- Safer, easier night time use. The backlit digital screen shows results clearly in all light conditions, with a choice of psi, bar or KPA. The screen is positioned on top of the unit to make it easy to see results. The built-in LED light makes it easy to use in low light.
- Excellent performance. The flat design stays stable during use, and the 3.3M cable makes it easy to reach each tyre on the car. The large on/off button and screen are located on top of the unit, making them easy to use.
- Versatile and tidy. The cable stores away quickly and tidily, and the air hose folds into the Inflator. It comes with storage case, and there’s even a holder for your dust cap when you’re inflating.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent unit, one glaring design oversight
*by S***E on 3 December 2021*

Note the 5 stars, it was nearly a 3 !The unit is simple to use, and simple to handle. The bag makes it neat and tidy to keep in the car, and secured. I tested with both car tyre and my daughters bike tyre. The car tyre needed 45 PSI, and the bike needed 55. By default the air hose has a screw on based connector, the screw on makes a solid connection and is easy to put on. Note also that the power cable is plentiful to go from 12v output inside car (cigarette lighter), to next to any of the wheels. No cable length anxiety for me. When first switched on, you can easily set the desired pressure in the unit of measurement of your choice, I stick to PSI and is easy to configure. When the hose is connected you will see a digital reading of your current pressure. When activated, the unit will start and you'll see the digital display start to increase. As soon as target pressure is reached, the unit will hold that pressure.Now... this is where the THREE stars was earned. All absolutely perfect until this point. What could possibly go wrong. Well, unless you're superman or supergirl, and you can spin the hose adapter screw at 10,000 rpm and make an instant disconnect; unfortunately, you'll be like me. I'm a mere mortal. For the bike tyre, the best I could do was drop a whopping 12 PSI in the time it took me to spin the screw thread enough times to get through the fully attached to semi attached (air now coming out), to half attached, to partially attached (air still gushing out) to finally detached. It's a ludicrous design feature. For all the mathematicians out there, I drop nearly 22% of the tyre pressure just trying to get the hose unscrewed from the valve. In anyone's book that's inadequate. The car tyre faired a bit better, just simply through volume of air. Even then I still lost a good few PSI, which means I have to pump the tyre up a few notches to estimate pressure loss through unscrewing. Doable, but what's the point of a digital pressure gauge.So, why the 5 stars? Well, this product is saved by a £6.https://www.amazon.co.uk/gp/product/B089NB65GX/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1Once fitted, you get a quick release locking tyre chuck at the head end. Instant disconnect, zero pressure loss. It's almost too simple. Shame it had to cost £6. Why something like this isn't included is a mystery. But there you have it. If you're prepped to purchase the adapter, this air compressor is an easy 5 stars. If you are a dare-devil, and stick with the screw piece you're better than me!5 stars because despite my gripe it works brilliantly, and it's so simple to use. Just get the adapter.

### ⭐⭐⭐⭐ Decent inflator
*by B***J on 15 September 2023*

Inflates quickly and great to be able to set the target pressure. Sometimes not sure it is very accurate, but useful when needed. Would be better if it had a nicer way to wrap the power cable instead of just a hole in the bottom. Good quality product, but the only really annoying thing is the connector to the valve is very difficult and poorly designed, and would be no use for people who dont have good dexterity in their fingers

### ⭐⭐⭐⭐⭐ Really well made and fast tyre pump
*by F***R on 6 December 2021*

I neded a new electric tyre pump as my old one (not Ring) disintegrated. Did some research and found this. I liked the size and that the target pressure was shown in the backlit display - my car has different pressures front and rear.In use it does take a few seconds to report a stable tyre pressure when attaching. It is really very fast to inflate and I like the screw on in-line connector rather than the 90 degree clip-on ones. It also has a deflation button if you need to reduce the pressure which is handy. Good length of airhose. Only downside is that when picking it up I find it very easy to press the pump button, but that is the fault of my fingers!Very good pump and very good value
