Jump Starter Power Pack, TOPDON JS3000 Car Battery Booster for Up to 9L Gas/ 7L Diesel Engines, Portable Car Starter Power Bank with Handle/Jump Lead/EVA Case

Meets its claimed performance admirably and had no trouble with starting a large V12 with a flat battery in seconds. Having done so it seems to have plenty of power stored in reserve to go again many more times. It takes a while to charge but overnight is sufficient to regain full charge from its mains-powered usb charger. Utterly safe, easy to use with weatherproof connectors. Small enough to be carried in the car in its own carry case to keep it all tidy and cheap enough for it to be a no-brainer for a car maintenance toolkit. Not a substitute for poor charging, end-of-life battery or serious battery drain issue but it will dig you out of trouble and seems rugged and well-built enough to last for years.

This item is not the cheapest, however, at £120 represents good value for great effectiveness. The unit is capable of starting even dead batteries and large engine sizes upto around 7-8 litre. Additionally, the outputs enable you to power, with a 12V cigarette adapter, things like tyre inflation compressors. It can also charge/run your mobile phone which is handy if you have a flat battery with a dead phone. To finish off the ensemble there is a bright LED light to enable nighttime operation. The unit has easy to use leads to connect it to your car battery to ensure safe starting without the need for traditional jump leads.

Very well built power jumper, great quality with a few other features apart from a battery jump starter. I used it once to get me out of trouble and it worked well easy to use

Wow! Only a few months ago, very few people had heard the name "Topdon," yet now, most of the favourite YouTube vehicle related channel presenters are using the brand, not all because of sponsorship deals, and I am delighted to say that this unit lives up to every positive comment and good review that the Topdon products have been given in the very short time since nobody had even heard of them. Mine was put straight to work the day after it had arrived, my older, and massively bulky, boost starter thing had failed to start my old Land Rover Discovery 300tdi automatic which had been standing on my drive for 14 months, its battery completely dead, following a spot of "failure to proceed," involving a power steering pump whose party trick involved emptying its oil in ever more embarrassing ways. So I found a good home for the old truck and the Topdon saw to it that the vehicle started after just two glow plug cycles and at the first turn of the key. My shock at this outcome was tangible, but the buyer was able to drive the old barge onto his trailer - pulled by a Disco 4 with a V8 and a soundtrack to match, I need one of those now😁 - and off he and my lovely 4x4 went, the deal prevented from going awry by Topdon! Now, as many Disco 1 owners will know, the 200 & 300 tdi are not the worst of Diesels to start after a long period of "rest," but even so, the product performs incredibly well and yes, all of the good things the we have been hearing about this new brand are true. Oh, and it comes in a very good quality carrying case, so no excuses for scratching it up in use! Have you got an old vehicle that refuses to start for any less capable device? Don't waste time looking at lesser devices, buy a Topdon JS 3000 and do the job properly. The old saying "buy cheap, buy twice" has never been more relevant, I wouldn't be without my JS 3000. What are you waiting for? Buy one of these now and take much of the stress out of participating in the bizarre hobby that sees otherwise sensible middle aged folk such as I refurbishing vehicles that are far more interesting than a new (insert pretty much any brand name here) car. Summary: Great build quality, far exceeds any expectations that I might have had of the device, easy to charge from domestic mains via its supplied 240v AC to USB C charger or a car via a lighter socket and a suitable lead terminating in a USB C, Capable of providing more boost / start cycles than any similar device I'd considered, tested and rejected Don't hesitate to buy one of these, I did and I'm now unapologetically a complete Topdon fan girl. Perhaps if I'd grown up playing with dolls instead of being drawn into the classic car world as long ago as the early 1970s, I might not be so evangelical in my appreciation of tech stuff? Thanks all for reading the above. More reviews coming soon relating to everything from shoes to makeup and jewellery via parts, tools and various fluids associated with vehicles. Stay safe, Jaye xx PS: I know and have to encourage the many younger people I know who prefer not to use new cars, my apologies for the implication that ours is a middle aged hobby, but in my defence, I am middle aged!🥺😉

Essential in winter

Can't believe how effective this battery charger is, from a completely flat van battery for two months to an immediate start with this product, easy to use, compact, good value and recommendation from garages, easy for women to use as well. Well worth£80 for long term use, I don't use the van every day so this product is ideal for me. Thanks very much.

Brilliant piece of equipment and was a life saver when I was experiencing issues with the electrics on my Defender which caused the battery to keep draining. Cannot recommend highly enough and this now goes everywhere with me - especially when I'm traveling solo and off-grid.

Great when it works but after a year and a handful of jump starts it doesn't work now, shows as 100% charged but as soon as you remove it from charger it drops to 25% and won't start a car

bon booster, n'est pas eu l'occasion de le tester plusieurs fois juste un essai , qui promet, livraison rapide, mais retardee par la météo indépendamment du transporteur

El producto llegó en perfectas condiciones y funciona muy bien

Worked well on a dead battery. Boost function works. Was starting a 2.6 litre diesel engine

Sie passt gut in den Handschuhfach meines Autos und ist einfach zu transportieren. Sie kommt in einem robusten Gehäuse, das sie gegen Stöße und Kratzer schützt.

I have had this since October of 2022 and I tell you that it works like brand new still. I'm still able to jump cars with ease the battery holds up very well after 3 years this was definitely worth it.
