Car Jump Starter, FLYLINKTECH 4000A 12V Portable Car Battery Booster Jump Starter Power Pack (up to 9.0L Gas Or 8.5L Diesel Engine), Power Bank with LED Flashlight, IP67

This is a great little piece of kit that is now a staple item in my car. Ordered one day and received the next. I was looking forward to testing this but was waiting for an opportunity. Then I get a call from a friend whose car had been sat on their drive for a few months and they needed to move it. Unfortunately the battery was completely flat with no life in it at all. I was happy to use this as a test on this charger and have to say it can through with flying colours. It was simple to attach the cables to the charger pack (no chance of getting these wrong) and clamped them snuggly and securely in to the drained battery. Then turned the key and the car sprang into life! It was immediate and was like a new battery had been hooked up. I simply and safely removed the charger pack and popped it back in its box for next time. Not only is it a neat little charger pack but also has a handy flashlight on it (very useful as this was in the evening) and has USB ports for charging phones, etc. If you are looking for a compact, durable, and effective charger, you can’t go wrong with this. Great product, great price. What more could you ask for. Highly recommended.

We compared this to a shop brought £90 device with the same specification and have to say what a powerful device. Multi uses as a powerbank, light and a battery jump starter - micro charger. I have 2 cars that I primarily brought these for but also a converted LGV motorhome and yes this small, portable, lightweight device will get all devices up and running. Its so small and compact that you can keep it in your day bag (and forget its even there). The material is robust. Well made and feels solid. Came well packed and instructions very clear.

I had a track day booked at Brands Hatch, 3 days before the track day my battery is flat, left the interior light on all weekend accidentally! Ordered this in the morning and it arrived the same day. I have wanted something like this for ages, however the price has always been a bit much. Then this came up for a very decent price. I chucked it on the car, and bang, instantly started up. Very easy to use. This has been put in my track day tool bag/car as a just in case. The amount of these being used (not specifically this model, but this type of thing) at Brands Hatch in the pits was crazy. It asks for a review of the Carry case but it doesn’t actually have one. It’s just a drawstring bag that’s a little too small. But other than that that it’s great. Seems nice and powerful and seems to do the job! I even used this to charge my phone on the USB port on my drive home as it charges quicker than the car. Torch that’s in it is very bright also. For the money, even if you use this once, it’s a bargain! Our local recovery are charging £80 for a jump off a NOCO. This will do that job easily.

Great piece of kit to jump start the car without the hassle of connecting leads to another car. Has helped me several times already! The only thing that's a bit annoying is that the span of the clamps could be a bit better as its a bit fiddly to get a secure connection on the car battery. Great value for the money otherwise.

I used the FLYLINKTECH 4000A for the first time over the weekend, and wow, I’m glad I had it. Even though I have breakdown cover, I didn’t want to sit around waiting for the recovery service to show up, so I decided to give this jump starter a try—and it totally saved me a ton of time. Quick & Powerful Jump Start This thing is seriously powerful. It jumped my car’s dead battery without any issues, even though my car is on the larger side with a 3.0L engine. No more waiting for a tow truck to get me back on the road—just hooked it up, and I was good to go in minutes. Great Value for Money I was honestly surprised by how much this little device can do for the price. It’s not just a jump starter; it doubles as a power bank too! The USB-C charging is super handy, and the fact that it can charge my phone or tablet on the go is a nice bonus, especially when I’m out on long trips or camping. Handy LED Flashlight & Waterproof The built-in LED flashlight came in clutch when I needed a bit of light while figuring out the car situation, and the fact that it’s IP67 rated means I’m not worried about using it in the rain or throwing it in the trunk with my gear. Honestly, for the price and what it can do, it’s great value. If you’re like me and don’t want to wait for help when your car dies, this thing’s a must-have. So much quicker and easier than waiting around for recovery!

This is a great product , I am a 60 + single lady + having found I had a completely flat battery Xmas eve !! and not wanting to bother anyone I decided to give this a try I ordered and it was delivered early next day the unit needs 7hrs to fully charge before use I was a bit nervous but after watching a you tube video decide I could do this and I connected the leads to terminals as instructed then turned on charging unit on now I entered car and pressed start button ( it’s a keyless car ) the the door lock button flashed but engine didn’t start so I removed leads and tried again this time display screen displayed that I needed to enter car code , I removed leads again found code and repeated process wow success the engine started !! I disconnected leads and kept engine running after this I drove around to charge battery for over an hour without lights radio or heater and a few days later all is still good Great little gadget to keep in boot for peace of mind and a good price on offer would recommend 👍

This item is useless! It may be that I got a bad one. I bought this in 2024 as a "just in case" item. I have tried to use it on three occasions and it has not worked once. Twice it simply would not start the vehicles - 1.9 turbo diesel and a 2.0 turbo petrol - apparently not enough power! Once, the leads were simply not long enough to stretch between the jump starting terminals under the bonnet and the battery itself was tucked away under a lot of trim inside the car. Now, it will not accept full charge, so I must find a way of disposing of it. At first I thought it might have been my fault, but I have another similar product in the USA and that has worked perfectly.

What a great bit of kit, and for such a reasonable price! The battery on the wife's car died after the car had been stood for a while. I was recommended to buy a jump starter, so looked online and hey presto. Ordered it around lunchtime and got it that evening! Charged it up overnight, as per instructions, then attached it to the car and started it no problem. When I initially saw the physical size of it, I doubted how well it would perform, but it's a little beauty and is small enough to be tucked away in the car. There are also ports and leads for charging your phone and other devices plus a cigarette lighter socket type lead. In addition, it has a powerful led torch light for if you're stuck when it's dark. I have only used this product once, but on the basis of that, would thoroughly recommend it to others.
