GOOLOO X7 Jump Starter with Air Compressor, 4250A Portable Car Starter with 160PSI Digital Tire Inflator, 12V Battery Booster

Simple to use and worked perfectly from the first use. Considering the low price it feels well made and the storage case is very handy.

I had doubts when I opened the box that something so small would be able to start my car's two litre diesel engine. The car had not been used for weeks and although the battery wasn't completely dead, it would not turn the engine over. I charged the device and then, following the simple instructions, connected the clamps to the battery terminals, pressed the boost button and turned the key. Wow! The engine turned over faster than I had ever heard it crank before. In a few seconds the engine was running.I recommend this device as in my opinion it is so easy to use and comes with accessories making it a versatile piece of kit. With it's torch function, device charging ability, and the fact that it can be used to power many 12 volt accessories, you need never be left stranded again. I found the instructions very easy to follow and It even has a failsafe so that if someone were to connect the clamps the wrong way round it warns you.My opinion? Buy one of these, pop it in the boot, and hope you never need it. Then on a cold wet night when you get back to your car and find the battery is flat because you left the lights on, you'll be glad you have it.

Its compact and does what its meant to do , it starts then engin one time. I love it,I wil recommend it for all car users.

I had to return a similar item to this, because the screen was all but invisible in daylight. When this replacement to it arrived, it was reassuringly weighty proving a substantial battery was powering it and it was so obviously not only well-made but well thought-out in every way too, not to mention beautifully designed. So much so, one really didn't need the Instruction Manual provided.I was thrilled when on a bright sunny day I could still "see" the screen contents easily but got seriously blown away when I pumped up a slow-leaking tyre on my Mercedes C220 Estate, prior to driving it to my local tyre-bay. From just 8 PSI to 34 PSI in less than 2 mins - wow, much, much quicker than even the manufacturers' claims on this one and so much quieter than my two previous ones to boot. Noticeably so.My car battery is just fine so I've not been able to test this (because I can't be faffed to disconnect my car's battery to do so?).All this and a bag to hold the whole kit & caboodle in too, really makes this inflator/jump-starter from GooLoo (X7) a real winner in my book (and the only one of its type in its class that inflates tyres up to 160 PSI).Just to confirm that as well, the obligatory USB C charging cable is provided as well as 3 additional and differing nozzles for the compressor hose for air-beds, balls etc, making this kit about as complete as anyone would want it to be?Yes, it's just a little pricier, but that's a small price to pay for the peace of mind I'll certainly get from owning this and having it in my car for those unwanted always least expected events.Why then have I dropped a star in this review? Well, it's only a niggly point, but the ONLY improvement I would like to have seen, was the battery indicator for this device should ideally be a digital one and not a battery icon with only 4 bars. If it had that, it'd be as close to perfection as it could possibly get in my opinion.Go on, buy it, take it from me you'll not only be well impressed but you'll also be well pleased with it. Take it with you wherever you go sand have peace of mind with you.

I bought this after a recent flat battery and wasn't honestly expecting it to work...But recently started my mother in laws completely flat battery and then only a week later my 2.3L ford. It was also completely dead. I had to use the key to get in!! Both booster off the same charge.Took a few attempts as the cars ignition drained the starter battery, but after a few goes, it started confidently!

Worked the first time and jumped started a hatchback petrol car with a flat battery on a cold winter morning. It was simple enough to set up and worked incredibly quickly. After one jump start, the battery indicator remained at 4 bars. Do make sure you read the instructions thoroughly and keep them with the battery pack. The charger looks robust and well made. The light and the ability to charge phones are very handy features. I am very happy with this product and will not be without it.

Absolutely fantastic. Arrived 75% charged, instructions do say to charge it fully before use however we needed it straight away; connected it to the car, pressed Boost, and started the car first time. It's now on a well earned full charge, although it was still at 3 bars after the jump start. Car was a Hyundai SUV type thing, 2.5 Diesel.Device itself is reassuringly heavy and unlike most Chinese devices, this one has clear instructions in proper English, along with safety tags on the jump cables themselves.

Very happy with this great piece of kit.Well worth the money, first time I used it this morning. Worked straight away!Highly recommended. Keep it in your glove box. Every driver should invest in one of these, happy days!
