A3 Jump Starter with Air Compressor, 3000A Portable Car Battery Booster (9.0 Gas/6.5L Diesel) with 150PSI Auto-Shutoff Tire Inflator, 12V Lithium Jump Box Car Battery Jumper Starter

Have been using portable jump packs since the only option was Heavy Sealed Lead Acid packs. I’ve brought from all the major companies Snap-on Noco ect.This brand was featured on a YouTube car channel and mentioned they had used for several months and found it to be effective.I brought this one to leave in my mothers car. And it’s fortunate I did as over the cold snap her car required a jump.The unit performed flawlessly. The state of charge was 80% and she jumped the car 3 times that day in below freezing temperatures. So her day was not disrupted or inconvenient waiting for help / recovery.The unit shows 74% that evening when she popped it on charge back at the house.Reasons we like.Very high build quality.Works well.Very fast recharging via usb C 100w compatibility.Good screen easy to understand for a non car person. You can’t connect leads wrong like say jump leads so much safer.Unit has a bright led torch and can charge / any phone or 12v car accessory like a tyre inflator.The price is very fair. I have a Noco which was almost £200 and performs worse than this unit and also has no fast charging ability.

Excellent product and great price

I wanted to wait a good while before putting a review of this item up. As we all know, products similar to this have a habit of failing when just out of warranty.However. This product has been faultless in every way.It has started my 3.6 Litre Turbo Diesel Range Rover from flat many times now using the BOOST button. It uses about 20% of the battery to start this vehicle from flat. But afterwards it will go up a few % again, only 2 or 3, but I guess that's just the batteries recovering.I have also used it several times on a 1.3 Litre Petrol engine. And that only uses about 7% from flat. Again, recovering a couple of % after use.I have left it for months sat inside my glove box over winter and it didn't lose any charge at all. I would be confident leaving this even longer, should I need to. Because even after being left that long time it still started all vehicles fine.It even can quick charge at 100 watts, with the right charger.I would say that this is a must have to keep in your car for emergencies.Not only for the ability to start your car, but also for the USB functionality of it. And it also has a 12v output on it with a cigarette lighter attachment. Meaning you can use 12v items on it, such as tyre inflators and so on.So, you can start your car, charge your phone, use 12v equipment, quick charge it. And the battery seems to last for ages.I have not found a fault with it in any way whatsoever! I bought an extra one for the other car and also recommended one to a family member. And I suggest you get one too :)

First off, the construction is very good, very rugged. The jump leads plug in satisfyingly tight, and all ports for charging your devices are well labeled and self-explanatory. There's a bright LED light with different modes to help you at night or in low-light conditions, although it's on the other side to where the jump leads plug in, so it isn't in the best place. I've only just left a review now as I hadn't had a chance to try out the Gooloo's jump-starting capabilities until tonight. One of my work colleagues was stranded with a flat battery, and I leaped at the chance to offer assistance with the Gooloo. At the first turn of the key, my colleague's diesel Kia sprung into life! My colleagues were impressed, as was I!There was one disappointment, although it's of my own making: this model does not have the pre-heat function for below-freezing temperatures (I hadn't read all the descriptions properly). The model with the pre-heat function can be bought for about £20 more from the official Gooloo website.All in all, this is a great piece of kit that instills confidence. I would recommend it.

Excellent product

Despite its small size, this packs some punch. When you charge it, it retains for a long time, and when you use it to jump a flat battery, the %battery is displayed, so you can accurately tell how many jumps you'll get before charging. You just connect and press the boost button. Much safer than jumping from another car as i'm told that spikes in voltage that wasn't a problem for older cars can cause expensive damage to the ECU of newer vehicles. My friend got one and uses for his tractor. So useful to keep in the car, eg if away on holiday and your battery is flat in the airport longstay at midnight- you've got this in the boot. Or the awkward time a friend asks you to jump his car, but you'd rather not risk you own car's battery or electronics- lend him this. Really good value, and peace of mind. I better stop, as I sound like I am doing an advert rather than a review. As for how many years it lasts, no idea, but feels decent enough quality. Perhaps just a slightly longer lead might be beneficial, but will fit any battery I've seen.

Great piece of kit. Boosts even flat batteries when there's not enough power to unlock the car. Great value for money. It's slim, portable & in it's own carry case.

Used around 2/3times to put 2-3psi in one tyre battery dropped to 50%.... now when I turn it on... it drops to 25% and turns off
