001 4000A Car Jump Starter, 12V Battery Jumper Starter Portable Jump Box(10.0L Gas/8.0L Diesel), Jump Start Battery Pack with 3 Modes Flashlight, Power Bank with USB Quick Charge & Type C Port

Why did you pick this product vs others?:This thing really works. I was skeptical because of the small size of this device. But it was able to start my F150 as well as my Mercury Grand Marquis without any problems. I love this new technology.

Works very well. My car battery died over 1 month and it got my car to start with only 3 bars on the starter.....i didn't even charge it.....i just took it out the box and start my car.Note: if there is only 1 light blinking after connecting the cables to the starter, it means it's not connected properly. You have to ensure both lights are blinking on the starter after connecting the cables.I love it, it's very easy to use and worth the money. Geat buy

Within a couple of days of receiving this, someone at my bar had a dead battery. It was a large pickup truck. Started it within 2 seconds. Much more convenient than pulling a vehicle around to hook up jumper cables. Will buy more. Cannot beat the deal at less then $30.Update: Needed to use it 5 times so far. Starts everything within a couple seconds. Today I had to use it on a large diesel truck. The owner said it will never start it. Couple seconds and it fired right up. Few days ago, the battery on my large 6-cylinder diesel generator was dead. Again, fired up in second. 5 starts with it and still shows full charge on the indicator. I've already purchased another one for my dad. He has a farm, and something always has a dead battery lol

The media could not be loaded. So it works great but I don't like how it blinks red and green as soon as I hook the cables into the box. Like why does it do that?? One time it took 3 to 4 cranks on a 06 Titan with a 3 year old battery in it and the battery in the jumper was dead and needed to be charged again, but while being stowed away it holds it's charge...I definitely believe it has 4000 amps but don't expect a bunch of tries out of it. Usually that means your battery needs replacement anyways and when you hook the cables to it get ready for a Christmas light show lol...oh and the built in light on it sucks and should be on the other side of the box. It points away from the battery....why?? Overall it does the job, big or small and the case is very nice and durable

This charger is absolutely amazing. It packs a very powerful charge. Charged it just as it instructed, and was very impressed at how quickly it started my car. The size is perfect to place inside the console of your vehicle for convenience.

Why did you pick this product vs others?:Works great, does what it's supposed to do. No issues.

I don’t know if it’s the type of battery my vehicle has but it did not wanna start it.

I already used it about 10 times! I live near Milwaukee so January and February can be brutal on car batteries (especially Walmart batteries)! I have multiple vehicles so sometimes my cars sit for over 5 days.Ok I was skeptical on buying this because the price was less than half of the popular ones. But I read a few reviews and took a chance.When battery was dead I hooked it up and instant ⚡️POWER ⚡️! Even when my dad's Lexus wouldn't start with traditional jump box, this thing did the job. (His car has electrical issues.)It's easy to charge, just use basic USB-C cable. I recommend using ur own USB cable because the included one is not Great.Even after several jumps the charge is almost full. I used to charge it after each use. Now I'm waiting to see how long it takes to drain the charge.You don't need the expensive units. This will do everything u need it to do. The carry case is great.
