Car Battery Jump Starter and Battery Tester TOPDON 2-in-1 2200A Peak Jump Starter for Up to 8L Gas/6L Diesel Engines 12V Portable Booster and Tester

I ordered this jump starter /power pack on the advice of a high end auto shop owner. He uses this jump starter in his shop. Everyone who owns a newer computerized vehicle needs to replace there jumper cables with this unit. Using jumper cables on today's vehicles runs a high risk of creating a voltage spike that can damage the cars computer controls...a very costly repair! This unit has circuitry that prevents voltage spikes, this is the reason professional shops use these. This is a quality unit is well made, compact with a nice carry case. It has the power, when fully charged, to start most vehicles including most diesel pickups. It will also charge cell phone. This is a good buy and should be in every vehicle.

Awesome company to work with, would definitely recommend them to anyone I know. The js3000 seems well built and it’s able to start my diesel tractor without any hesitation, best part is that it’s a lot slimmer then the one I keep in my truck. Also if you’re in the market for a larger one topdon offers a V4500 jump starter that’s an absolute beast! That one outperforms my tool truck one that I own in so many ways and the best part is that the top don is a fraction of the weight compared to my tool truck one

I love having the peace of mind this jump starter gives me. I have used it numerous times to help others and they are also impressed. It’s easy to connect to vehicle and starts on first try. I bought 4 more, one for each of my adult kids to carry in their vehicles.

This bumper box is awesome for the most part. It’s compact enough to carry anywhere- fits under a seat or in a trunk no problem. Like stays on the top of my tool box. Cable length is long enough to reach even heavy duty top wing nut batteries. It works, and it works AMAZINGLY WELL. Attach the cables and the unit auto detects the battery. If it’s low, hold the boost button and start the vehicle. You have about 15 seconds of start time before the boost feature disables.The limited boost time is one of the things I don’t like about it. The jump pack stops throwing voltage after the boost cycle, meaning that if the battery doesn’t have enough charge, everything shuts off. It would be nice to have a fast charger to come with it.That being said, this thing is an awesome value for the money. It started a completely dead 6.7 powerstroke f450. I mean completely dead- oth batteries had 1.5 volts. It started a 7.3 powerstroke that has been sitting on the lot for 5 years. I had to use the pack twice, because the first time was just for fuel priming. Started the truck up both times without issue. If it’ll do that old 7.3, it’ll do any regular vehicle you want it to. It also has emergency lights, and can double as a power pack.

I like this jump starter because it is a good product small in size but powerful,it started my semi truck in few seconds.

Works perfectly for everything I use it for never had any issues

I bought one on these in 2020. Still charges to 100%. A friend wanted a jumper but tired other products. All had to be returned because of small flimsy jumper handles.Top Don is the only product which had heavy duty, well made handles.Top Don is a great product. Don't waste your time on other brands.

I’m a mobile mechanic and I’ve had time to use this with 2 different cars now and it’s worked great haven’t had any issues I just charge it overnight and throw it in my car. I think everyone should have a jump starter in their car even if you don’t work on them. JUMPING PEOPLE FROM YOUR CAR CAN CAUSE MORE HARM THAN GOOD THESE HAVE COME A LONG WAY.
