GOOLOO Portable Lithium Jump Starter GE3000 3000A Peak Car Starter for Up to 8.5L Gas or 6L Diesel Engine 12V Car Battery Booster Pack with LCD Screen, Power Bank + LED Flashlight, Type-C Port

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 tool to have in your car. Easy to use and works straight away in my BMW. Fast delivery, still fully charged without charging for a month. With the price and quality, I would definitely highly recommend it.

Good for the price

After sitting in the car with the radio playing it wouldn’t start, this got the car started straight away, but it is vital to read the instructions, it paid for itself as getting a mechanic to come would have cost more

It didn't work the first time I used it but I think my battery was very, very weak when I tried using it. A friend came and managed to get the car started using a bigger battery booster pack. I had to use it the following morning and afternoon, allowing me to go and get a replacement battery after work. It hasn't always started at the first attempt but it has on the second one. Good piece of kit to have in your car, and bought at a good price!

Car battery completely dead. Couldn't even get radio on. Bought this life saver (Gooloo GE3000) for under £30. Very simple to use. Stick the clamps on the battery terminals (red on + first then black on -) and start the engine. Worked first time. Unplugged the clamps then removed from battery. Turned engine off. And started again engine again twice without any problems. Great to have such a portable device. You could pay a bit more if you want a tyre pump as well.

This helped fix my car over winter with a weak battery and has been so useful to get my car up and running multiple times. Easy instructions and works well.

Been meaning to get 1 of these for a while This item is well made bigger than what I thought it would be !! Cables seem alittle short but not used it yet so probably be the right length!! Comes with a nice bag to keep it in !! Charge it once u get it as mine was only on 72% when I 1st turned it on Seems fairly easy to use good price for a peace of mind putting in the car so I am winter ready !!
