TREKURE 4000A Jump Starter Power Pack, 12V Car Battery Booster Jump Starter (up to 9.0L Gas or 8.5L Diesel Engine), Car Starter Power Bank with LED Flashlight, Jump Pack with Jump Leads

I’m genuinely a bit in shock by this. Due to illness, I hadn’t driven my car for a few weeks and with the cold weather as well, the battery completely died to the point that the key fobs wouldn’t even unlock the car. I bought this one because I couldn’t justify spending nearly three times the price on a similar one I saw listed that had more reviews. I charged it up to 100% and took it down to the car to try it. I followed the instructions and once everything was connected, I turned my key and lo and behold, my engine started immediately. I honestly couldn’t believe it. My husband doesn’t drive and we live away from family, so I don’t really have anyone nearby to rely on if something like this happens. I was genuinely surprised at how easy this was to use. If you’re like me and want something compact, good quality, quick to charge, and works, I’d definitely consider this. After using it once the power pack battery dropped to 75%, so I reckon you’d probably get around four jump starts out of a full charge. I’m planning to keep it in my car for emergencies and just recharge it once it drops to around 25%.

Absolutely fantastic bit of kit - for it's size it really does what it says. I bought the previous model to this one and I have used it a few times including helping out my brother to jump start his 3 litre BMW sport - no problems whatsoever! I had to bail out my grandaughter earlier this week in the multi storey car par to get her home from work - again no problems whatsoever. I decided to let my daughter keep the older one just n case her or her 2 car driving daughters ever get stuck. It's a really powerful, compact and very lightweight unit - much better than carrying around those really big and cumbersome heavy units of old. It also has a really handy light built in and can also be used as a power bank for charging phones etc. Although (hopefully...) not a regularly used item, it is a handy unit that can be stored in your glovebox. All in all, i can really recommend this starter and I am pleased I purchased this specific model.

Jump Starter Power Pack, TREKURE 3500A Peak Car Battery Booster Jump Starter: Great design, compact and sleek. You can get your car running again quickly and independently without the need for anyone or another vehicle. The device only need to be charged once and then it stays charged for ages. I would tecommend to check them every 6 months or so to make sure it has got charge but that`s just for safety as I never had a problem with the battery draining. The torch is powerful compared to the older version. The added benefit of having the USB charger for electronic devices is great if you are going for camping or something like that. The charger level indicator is very handy to keep an eye on the charge. Overall I am well impressed with the practicality and design of this product. I would highly recommend to anyone who wants to buy a jump starter without relying on a breakdown service or another car to resque you if you are stranded.

I always like to have one of these things in the car as I have had to put up with a parasitic drain to the battery for many years. I had to leave the car parked and unused for just over two weeks and on my return the battery was completely flat........completely. I connected the power pack up and lo and behold a few moments later the car was running well, although the car turned over quite slowly on start up. The battery was still very flat after start and needed to be fully charged but this item performed as it should. Highly recommended. It is much smaller in dimensions than I thought it would be and it looks to be solidly made with good quality crocodile clips. It comes with a charging lead (cigarette lighter plug). I think it's a good buy. I hope this helps.

Saved My Day – A Must-Have for Every Car Owner! I can’t say enough good things about this jump start kit. It’s compact, powerful, and incredibly easy to use—even for someone with zero mechanical experience. I bought it thinking I might eventually need it, but it paid for itself the very first time my car battery died in a parking lot. What impressed me most was how fast it brought my car back to life. No waiting around for roadside assistance or asking strangers for help. Just hook it up, push a button, and you’re good to go. The built-in flashlight and USB ports were a nice bonus too—great for emergencies or even charging my phone on the go. This thing is now a permanent part of my car kit. Peace of mind in a box. Highly recommend it to anyone who drives

I am really pleased that I bought this item. It's a small handy size but is robust and works well to do the job intended. Its recently been used and I'm pleased to report that it performed well. It comes with its own storage bag so it can easily fit in the glove compartment or boot. It has a built in bright torch/ emergency light which is very useful in a breakdown. I'm very impressed that its also a power bank with a port for charging such as a phone. There is a clear indicator of the charging levels and the smart jump leads are very sturdy and well made. It's excellent value for the price. I would recommend this product to anyone looking to buy.

I purchased this in July 2025 and it seemed to be a good product. I have used it to charge small devices and the flashlight feature is useful. However, my main reason for purchase was to start my car in the event of a flat battery (which has happened several times for no apparent reason). It happened today. My Peugeot Rifter diesel automatic had gone into energy saving mode and had a flat battery. So I connected up the Jump Starter Power Pack and the car immediately responded by going out of emergency power saving mode. But then I tried to start the car and . . . . . nothing. The Jump Starter was at 100% power and showed the green light but it did not have the power to turn over the engine. When an engineer arrived he laughed at my power pack. The one he uses is about ten times the size and he said that such a power pack would only work if the battery still had a lot of charge and just needed a bit extra. So basically, it will not start a car with a completely flat battery and is a complete waste of my money.
