Jump Starter Power Pack with Air Compressor,UTRAI 4000A Car Battery Booster Jump Starter,Portable Car Power Bank with Jump Leads/18W Fast Charging/Emergency FlashLight,8.5L Gas/6.5L Diesel

I bought this when it was on a 38% discount deal. Had I paid full price I'd rate it 4/5 otherwise the rest of this review still stands. I've tried to provide a lot of detail as I think this is a very good product that's worth having in your car for almost all drivers.Prior to owning this I carried a separate car tyre inflator which connected to my car's cigarette lighter outout. Jump starting could only be done using the cables I carried, which naturally require another vehicle. My car has USB sockets to charge a phone, but of course that relies on the battery of the car working.Initially I was looking at getting a premium product from Nebo that does the same 4 functions as this one: tyre inflation, jump start, USB charging and a torch all in 1 unit. I'd never heard of UTRAI but given how many great reviews it had (and how few the aforementioned product had) I decided to investigate further.Upon arrival I was impressed. This comes in a sturdy black/red case which keeps it all together and clean. You get: the unit itself, jump leads, a tyre inflation hose, some tyre hose nozzles (for different applications such as bikes) and a USB-A to USB-C charging cable.The USB connectivity was my first disappointment. Although this has both a USB-A and USB-C port, the C port is only used as an input for charging it up. This means you don't have USB-C output so if you have a modern phone cable - with only that type of connector - you can't plug it in to this. You'd need the (older, wider) USB-A plug with a USB-C end, which you can buy for not very much. Bizarrely, this unit actually comes with one of those USB-A to USB-C cables for charging it, so you can just use it in the opposite direction. That said the cable is incredibly short. This particular point is the main one where it falls short of the Nebo offering - on theirs you can use both ports for output so could charge 2 devices simultaneously and with different cables, whereas this is a 1 device at a time deal.I charged it up which took over an hour and I believe it was on 3/4 battery when delivered. It says in the instructions to check every 2-3 months that it's recharged, which is acceptable.I used the torch which seems reasonable for an emergency situation - not the brightest but it would help in the dark.The tyre inflator is excellent. It shows units of PSI, BAR, and a third unit which I've forgotten. This is nice because some car manufacturers give tyre inflation recommendations in different units (for example my Honda used PSI whereas my Toyota has BAR figures written on the plate inside the drivers door).The only other downside I came across is that the manual is written in a poor standard of English. You can make sense of it but it really cheapens the product in my opinion because it feels like no care was given to this quite important aspect.The unit in it's bag fits very easily into the car boot in one of those side cubby holes. It would depend on your glove box size as to whether it would fit there. Basically, it's compact enough to not be tedious to carry, which is really all you need to know here. It isn't overly heavy for what it does.Overall this product gives me a lot of peace of mind whilst driving. I drive about 15k miles per year and sometimes I'm in remote places. Knowing that I can jump start my car, use a working torch, inflate my tyres and charge my phone is a massive stress reliever. It's also great for general car maintenance such as checking/topping up your tyre pressure because you don't need to walk around the car with a cable plugged in.The downsides for me don't override the greatness of this product. Is it worth having? Yes. Is it worth the full price? That's up to you - personally it was well worth it for me at a 38% discount but if I'd paid full price I'd think it's a tad expensive given the previously mentioned flaws. I don't regret buying it at all and have already recommended it to somebody else.I'd advise buying a longer (say 1 meter plus) USB-A to USB-C cable if you get this. These are only a few pounds and significantly help both the phone charging issue and even just charging the device itself.

This is my second jump starter from this brand, my daughter now has one. They started car first time after flat battery.I have now the slightly bigger one with the built in inflator, comes with all cables in a handy travel box fits under car seat. Very pleased

I have two classic cars and both are parked and then driven every couple of months. I used to get the long jump start cables out and connect to my regular car to start. However used this device after reading the instructions. Very simple boost to the battery by connecting and pressing the small button on the side for 3 seconds when you have a green light. Got back in the car and started up first time. Also used air pump and worked fantastic. Used it on a flat football first and it blew it up in a few seconds. This is not exactly a cheap bit of kit, but it’s made very well. Came in a nice case to keep things tidy and organised. It charged up using normal type c cable. The boost did deplete by from about 97% to 86% on that single boost to the battery. That could be as my battery in car was very low and needed that extra bit of juice.

Out of the box the product looks really good and was easy to use. Nice and simple. Just brought it to keep my car at the right pressures. It will also be useful for other stranded motorists I may come across

Really love this product when I needed it worked straight away (starting my car) made from strong materials and feels like it’s well made. Had many functions on it and doesn’t take long to charge.

Seems to work fine. Won’t really know unless I have a flat battery but the other functions work as they should.

To help me jump start my car

I have had reason to inflate a car tyre from flat and it used one of the 5 bars on the battery. Obviously not a fast as a garage pump but still only a few minutes and I am very impressed.The case holds the bits nicely without adding too much bulk or weight.It has replaced 2 items and so halved the space which is important to my as it is primarily part of a tool kit I take when mororcycling around Europe.I paid and have no connection with the brand or seller and I consider it to have been excellent value.
