Arrived on time, instructions a little vague but easy to set up, wanted it for going around the Motorhome, just easier without cables, topped up to 72 psi, took a little time but managed it, did rear tyres only as they were low hopefully it will cover all 4 but can use 12v as well . Watch the temperature of tube ends especially on unit as they can get hot, pleased with it though.
I drive a M3 E92 V8 with Pirelli P Zero front 245/35Y and back 265/35Y 19 inch so require precision tyre pressure.
This product covers it all. It is so compact, well built, does all 4 tyres without any problems. One charge job done.
Best inflator and it’s mobile no need to plug into cigarette lighter. Highly recommended. Only watch out when removing metal connector on hose on product. It’s hot hot.
It’s a superb inflator overall. Battery life is the weakest point as it does need to be charged after a couple of top ups though it’s easy enough and the case has a little cover to access the charge port.
Accuracy seems to be pretty close to my gauge (which is very accurate) but more importantly it’s consistent so I’ve got it set slightly higher than the pressure I’m aiming for which gets it exactly right according to my gauge.
There’s a memory function as well so you can store pressures for multiple cars.
The unit is quite noisy as expected for a compressor and is so convenient I don’t think I’ll be going back to foot pumps or 12v powered compressors unless I forget to charge it and have no battery life left.
Would very much recommend.
Came with a full charge. Was so pleased to see how good a quality it appeared to be and even happier when I used it on a problematic car tyre.
Easy to charge, easy to use, good quality unit, cables and carry case…..real excellent product.
Chuckled at how much puff the unit puts out for a USB rechargeable unit.
Hope the unit holds charge over time, tine will tell but can gladly give this 5 stars and highly recommended.
Great to have to save waiting at petrol stations and feels like it will last a long time.
Money really well spent I feel.
What a great little gadget and also love the fact it has a nice little torch on it, missed that in the advert spec, really useful.
Great item but unfortunately doesn’t work properly. Inflated only for a second or two and then turns off completely.
Used on a trip 3 months after buying it worked fine but thereafter developed the fault.
Ring automotive have been helpful via email but Amazon not so.
Future advice on electronics would be to buy local where you can get better support for a faulty item.
Compared to other cordless options, I like this as it has an internal battery which can be charged via a USB or 12v socket. No swapping a power pack for a corded power pack. If it runs out out of battery life mid-inflation, the same 12v charge lead will power it. Easily topped up 4 tyres on my Tesla on one charge with no dent in the battery indicator.
Not overly noisy, compact and with a clear backlit screen with a memory function to save having to remember the required pressure. Thought this a bit daft but works really easily. Cuts off when pressure reached.
It comes with a case and can remain in this when charging or being powered.
This is really a good device and being rechargeable makes it a lot easier to use. But there are some limitations:
The unit struggles to inflate tyres in cold (<5c) which is not really a surprise
It easily inflates 4 tyres from 28pi to 33psi (10 centigrade)
It can only manage two tyres from 20psi to 33psi
Within these limitations its great. Be prepared to charge the battery every time you use i
It’s much smaller than expected. Charged it for an hour or so first. Have inflated two car tyres – one from 20psi, the other 29psi, both inflated to 33.5psi in no more than 5mins. It is now showing red to recharge, so not sure whether I hadn’t charged it enough, or if it really can only do one longer charge (or from flat) before the battery runs out. It’s not quiet but definitely not problematically loud.
One star deducted for poor instructions (but it’s easy to figure out) and also the lack of a lever/clamp style connector. I bought one at the same time – just a few pounds and saves losing any air whilst disconnecting, which happens with the thread type connector included.
