Portable Car Jump Starter 4000A: 12V Battery Jumper Emergency for 10.0L Gas Diesel Engines, Power Booster Start Boost Charger, Intelligent Protection, USB-A Type-C Ports with mutifuctional Light

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

Really good bit of kit! Cheap for me in sales but I would pay full price it’s worth it! Fits under my seat, charges in couple hours, seems to last but I don’t need to use it only for emergencies, torch light is handy! All rounder works. Easy to use.

I Have Purchased 3 Other Jump Starters over The Last Month, And had to Return them for A Refund because they Hardly turned the engine over, and Didn't Work ! This Particular One is 100% Brilliant and Started My Car With A Flat Battery Instantly, and used Hardly Any Power ! Proven Quality, And Would Highly Recommend !!

Item arrived with about half a charge, after fully charging it used it on a 1.8L Ford Focus with dead battery. Connected clamps and tried to start engine. For a second it didn't sound it would work but then it fired up. After disconnecting still showed full power. The battery unit does feel plasticy but still seems sturdy. The clamps feel heavy duty with a strong spring action. The carry case is semi hard, not blow moulded but stiffened material. Zip doesn't look the best. Large bottom section for battery with elasticated strap to hold it in place. Zipped netted area in top which holds clamps and other accessories. After single restart, item worked as required. Haven't tried compressor function. Will update as and when it gets used in future

Perfect item, does what it is needed for but went from 100% charge to 64% on one jump start.

1st jump start successful - completely dead 2.2L diesel camper, not evenights on the dash, 1st turn. 22% battery capacity used. Good kit for the price (paid 40 pounds) . Will see how long this last. Will update

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!

Really nice product. Well packaged. Works very well. High power jump start, yet we'll sized and doesn't fill up space in the car. Buttons could be easier to understand but its a five minute learning curve.

Sprytne urządzenie, warto mieć zwłaszcza jak się zostawia auto na lotnisku na miesiąc. ;)

初めてこの手を使ったのですが バッテリー上がりも簡単に解消されるし 使いやすさもあって感動でした。

Livré dans une sacoche semi rigide avec rangements pour chaque accessoires, le top !

Have used it 3-4 times now to help people out. It works better than I expected! It might be one of the best items I bought recently. Since its battery powered I have been able to help two people in a situation where regular starter cables wouldn't reach. As of the battery, I have just charged it for the first time, and it was on 3/4 bars. And that was after starting those cars previously mentioned. Highly recommended. Only drawback is the plastic casing which feels a bit cheap.

Un appareil vraiment de qualité la voiture redémarre au quart de tour franchement je recommande vivement pour des personne qui on des soucis de batterie le rapport qualité prix est formidable
