– JS3000 Portable Car Jump Starter, 3000A for 9L Gas,7L Diesel Engine

If your looking for a powerful jump starter that's easy to use buy this! I work for a big car group in the Midlands and we have lots of brand new and used vehicles all different brands etc, One of the vehicles that are a pain are the brand new Ford Transit custom (The new VW transporter) They kill my Noco GB40 on one press of the ignition ( I am honestly blown away by this starter) The start time with this jump starter is amazing, power it up and if you need to boost the battery just press the button and away you go! Another vehicle that are a pain are the Ineos grenadier I put the Topdon jump starter on and it started up straight away! This is the best thing I have bought and I would also recommend the Topdon BT100W, It's a battery tester and you can also download an app from Google play or the app store and see how good batteries are absolutely fantastic! Great value for money, Highly recommended. Thank you Amazon and Topdon.

Small compact battery starter packs a punch. Started my 30 year old land cruiser 4.2L DIESEL no problem and that uses 2 x 12v batteries to start. Stick with the 3000 model for larger engines.

My car battery was on it's last legs as it wouldn't hold the charge for more than a week. Plus, the car alternator was not the most efficient after 20yrs of service! However, I did not have the time to search for the replacement battery as to where best to purchase so I purchased the TOPDON 3000A battery booster as a reserve for trips long or short. What a wonderful product the TOPDON is as I had to call upon it's use several times and got me out of trouble away from home. Whilst being weighty, the JS3000 is actually quite compact and comes with it's own carry case keeping all leads and accessories in one place. The jump lead is simple - there is only one-way to plug into the charger by way of the asymmetric plug shape (avoids any errors), and the sturdy jump crocodile clips that connect to the battery. Operation is straightforward - turn on, and press the booster button which prepares the charger to give the boost. My car is a 5.5litre V8 engine and therefore the electrical current required to turn the engine over is quite substantial. Using the JS3000, the engine turned over with no issues, just like having a full charged battery. Love it! I now carry this with me on all journeys and compact enhough to give me peace of mind. Highly recommended!

This thing is a unit holds battrey very well. And jump starts cars in an instant. Especially with the cold weather car battreys are always weaker but this starts a flat battrey too. Amazing. But its a very big kit. But with the case its amazing. I own 4 topdon prodcuts. Easy to use. Amazing safety features. Reverse polarity proof. Portable. Charge rate is quite good as long as you use a 30w charger at least it'll be fast. Functionality wise its amazing has boost mode too revive depleted vattreys but warning you do lose the protection features once boost is on

This topdon car battery starter is great for getting your car van truck started its peace of mind doing it yourself rather than calling other services that will cost you a lot of money. its very easy to use has great power and the battery life is great within two minutes you can start your car and be on the road again.

We own a Citroen Relay camper conversion & travel across the UK & occasionally into Europe occasionally, We carry heavy duty jump leads in case of battery problems, but some of the remote places we get too, means there's very little help available should we need it! this Topdon JS3000 has solved the problem! It's an exceptional bit of kit,we've helped out numerous other campers with battery problems since we've had it van three times, with almost zero battery, a panda, and my camper, every time I was amazed by the speed with which the starter goes, in a moment it starts anything. It comes in a sturdy and comfortable case, excellent cables, well-insulated and soft, low weight and a series of other opportunities such as light and USB sockets to power tablets, PCs, which I have not tested because for me its main purpose is starting up, a purpose that it does with great simplicity and efficiency. You really can't put a price on the peace of mind this unit gives us! I'd highly recommend this to absolutely anyone without worry! We've been that impressed with Topdon we've also purchased the Artidiag800BT Scan tool & the BT200 Battery tester, all really are "Top Quality"

After a prolonged 3 months in America, my car had a flat battery and needed charged before it would even operate the door locks. Whilst there my host was stranded with a flat battery. A friendly passer by offered the use of his jump starter pack after telling us how good it was and how it had already started his car a few times, but it had just been charged. It failed to start the car. So my worry was that any jump starter may not be up to the job. No worries on that score. Even after I had driven 500 miles at the weekend and I thought that my 2 litre diesel would have a full charge, it then went and failed outside my own house after a 50 mile trip as I was dropping my neighbour off. Out came the Topdon JS300 with some trepidation. I needn't have worried. It powered up first time and every time since until I managed to get hold of a new battery. I must have used it a dozen times, only recharging it when the led's indicated 75%. The Topdon JS300 is now stored in with my spare tyre and toolkit, just in case. It cost much less than a call to a breakdown service and didn't cost as much as a new battery and I've now got peace of mind.

Don't waste your money on a noco or other cheap packs. This thing is perfect for starting most things. Will start my transit and my Vito from flat with no issues. Usb c charging is a winner compared to a noco that seems to stick to the dark ages of micro usb ! With a good power supply it charges in a fair time. Obviously it's got a fair size bank to charge but once it's charged it's always ready to go should you get caught out

mein Oldtimer Kfz, was über ein Jahr in der Garage stand, ich keine Überbrückung wollte, ein vorhandener Booster hatte es nicht geschafft, die Batterie zum Starten zu bringen. Dieser starke Booster hat es im zweiten Anlauf sofort geschafft, dass der alte Mercedes sofort wieder angesprungen ist fantastisches Teil und auch leicht für eine Frau zu handhaben. Die Klammern für die Batterie sind extra groß, was ganz wichtig ist zu erwähnen, damit man diese gut an den Plus und minus Polen anbringen kann. Normalerweise sind diese bei anderen Modellen einfach zu klein und zu knapp gemessen.

Incredibile la potenza di questa avvitatore. Sono riuscito a fare partire vetture di grossa cilindrata con la batteria completamente scarica. Lo consiglio a tutto e non lo presto a nessuno 🤣 Compratevelo che per quello che fa non costa niente

Es el segundo que compro. El primero lo regalé a un familiar al que tuve que pedírselo prestado cuando me falló la batería. Arrancó a la primera aunque en modo directo y con 99% de carga el TOPDON. Ahora tengo uno que siempre llevo en el coche.

Bon un booster c'est un peu comme un extincteur. On ne s'en servira pas forcement, mais quand on a besoin c'est trop tard pour l'acheter ! J'ai choisi un produit de marque pour ses performances et j'espère sa durabilité l'avenir le dira... C'est en plus d'un booster une power Bank très performantes pour les smartphones, mais pas seulement. De même l'éclairage est puissant et durable (important en cas de panne ou accident sur la route de nuit). Au vu du produit et a sa tenue en main on a vraiment une impression de solidité. Un chargeur USB est fourni. La sacoche est robuste. la notice est claire mais il manque des (une) informations importante : Ne brancher le booster que le minimum pour démarrer, car en plus du courant de démarrage le booster va charger en même temps la batterie avec une intensité bien supérieure a ce qui est préconisé pour sa durabilité. Le role du bouton « boost » n'est pas suffisamment détaillé et explicité ( son rôle est mal compris par 99% des youtubeur qui testent le produit). De même pour la durée de vie de la batterie du booster il est il est fotement déconseillé de l'utiliser lorsque sa charge est 50% ou moins . Toutes ces choses sont dites dans la notice mais les conséquences du non-respect ne sont jamais dites clairement (diminution de la durée de vie des batteries (boster et batterie du véhicule) .

Genuine powerful jump starter. Also It can start heavy truck too not any issue. Awesome powerful product
