The best Jump Pack I’ve used at this price.

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.

Powerful jump starter!

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.

Jump Pack.

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.

a must have

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.

Poor battery life

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
