Car Battery Jump Starter, TOPDON JS3000 12V 3000A Battery Booster Jump Starter Pack for Up to 9L Gas/ 7L Diesel Engines, Portable Car Charger with Handle Jumper Cable and EVA Protection Case

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!

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"

Highly recommended.It jump starts many times before it needs a charge.Great quality!

Good bit of kit, good size so not a lump to lug around.

Great value for money, Highly recommended.Thank you Amazon and Topdon.

Very solid and well made piece of equipment. I have charged it up fully now but have not yet used it in anger. I am quite sure it will do exactly as it says on the tin though.

Was contemplating buying this for so long, I didn't know if it was worth going for the bigger one but this has been superb for me in the short time I have owned it, it started my dead 4.6 v8 range rover in no time! And has never failed me yet, super handy to keep in a glove box as its very small and light weight. I really can't see a need for a bigger one unless your car maybe completely flat? But then you should probably trickle charge anyway!
