GREEN KEEPERPortable Car Battery Jump Starter: 3000A Battery Jumper Pack for Car Engines Up to 8.0L Gas/Diesel, Ultrasafe Jumper Box with Jumper Clamps & Emergency LED Lights, Power Bank with PD65W Quick Charge

Just had a chance to use it for the first time this morning, on someone else's car. It was very simple to connect up and the car with the gutless battery started first time. Very impressed and pleased that I had it.I bought this neat little device to carry around in my EV just in case the 12v battery on that failed (which it never has) and also so that I could jump start other people's cars (I always carried jump leads in the past for this reason, but the EV's 12v battery can't be used with those).I've yet to try starting a car with a completely discharged battery but that seemed like a pretty important feature when I was considering which jump starter to buy.Pros: Simple to use, plenty of power capacity, seems to be solidly built, packs into a tidy little case, has potentially useful additional features (emergency light, powering coolbox, charging phone etc), holds its charge for a very long time when not in use and is very good value for money.Cons: None

I recently got my hands on the Portable Car Battery Jump Starter, and wow, what a lifesaver! This little powerhouse packs a serious punch with 3000A, making it suitable for car engines up to 8.0L, whether gas or diesel. If you’ve ever found yourself stranded with a dead battery, you know how stressful that can be. This jump starter is like having a trusty friend in your trunk, ready to help you out in a pinch.One of the standout features is its ultrasafe design. The jumper clamps are super easy to use, and I felt confident connecting them, knowing that the built-in safety features would prevent any mishaps. There’s nothing worse than trying to jump a car and worrying about sparks flying everywhere!And let’s talk about the LED lights. They’re a game changer, especially during those late-night emergencies. I can’t tell you how comforting it is to have a bright light when you’re working on your car in the dark. It really adds to the peace of mind that comes with this jump starter.But wait, there’s more! It also doubles as a power bank, and if you’re like me, you’re always on the lookout for a quick charge for your devices. The PD65W quick charge capability means I can power up my phone and other gadgets in no time, which is a huge bonus.Overall, I can confidently say that this Portable Car Battery Jump Starter is worth every penny. It’s compact, user-friendly, and truly a must-have for anyone who spends time on the road. Whether you’re commuting, road-tripping, or just running errands, you’ll be glad to have it by your side. Trust me, it’s a purchase you won’t regret!

Superb, it was a life saver when my car battery suddenly died. Reverse polarity and short circuit protection are great features, though obviously I have not tested these.

This product is quite good surprisingly. No issues with the battery jump pack

Not used it yet but looks like it’s going to be a nice bit of kit

An absolutely brilliant piece of kit. Has helped me and my old van out twice already, on these frosty Northern mornings. A great price and very easy to use. Takes a little while to charge via the USB, but once there seems to keep it's charge well. I would be very happy to recommend.

Bought to start a 5.7L petrol engine car with a failing battery. No issues with starting, BUT you'll only get 2, maybe 3 starts out of it.When charged (which does take some time), it seems to hold charge really well.Not much I can say beyond that other than the carry case is really nice, and keeps everything together

This is brilliant, never used one before and it was so easy to use to restart my car. I would definitely recommend buying this.
