Scatach002 4000A Car Battery Jump Starter,12V Jump Starter Battery Pack (up to 10.0L Gasoline and 8.0L Diesel Engine), Portable Jump Box with LED Display, 3 Modes Flashlight and Jumper Cable

I was SHOCKED that this thing actually worked! A few days ago, a technician told me my battery was near the end of its life as I was getting my oil changed. But I figured I'd still have time to shop around for a decently priced replacement. Well, me being stupid, I forgot all about the battery not being good and while I was cleaning out my car's interior one night, I turned the key slightly so the music would play and I'd have some light. Long story short, within 15 minutes, the battery COMPLETELY died. It wouldn't even make that cranking sound when you turn the key! Just nothing... Thank God I was in my own parking lot because I don't have jumper cables with me foolishly. Even if I did, I don't know too many people in my area that I felt comfortable asking for help from some I'm fairly new to this city.After doing some research, I was a bit skeptical about this thing, but I figured, I wanted to wait till my next paycheck before dishing out $200 on a brand new battery if I can. And this was cheap enough, as well as I figured I could just return it if it didn't work. Plus, it can double as a phone charging power bank, which I need cuz my phone is constantly dying lol. So I figured I'd give this one a chance.After charging it up to 100% once it arrived the next day (which I can't remember what the charge was exactly, but it was already over 90% for sure), I went out to give it a go, not expecting much. And to be fair, it wasn't JUST because I had never seen these devices and it sounded too good to be true, but also I knew my battery was basically just fried and at the end of its life cycle anyway, so I didn't even know if it was POSSIBLE to save in the first place. Anyway, I hooked it up as per the instructions, turned the key, and BAM! The engine started up immediately!! I unhooked the battery thing and saw that it still had 99% battery left in it somehow too! I couldn't believe it!I'll definitely be keeping this with me in the car forever from now on until the day I die (or can't drive anymore for whatever reason lol). And I personally feel good recommending this device to literally everyone. It's cheap and it could save you tons of money or at least a headache. Worth it to me!

It's best that you always make sure these type of products are charged to the fullest in case you need more than one jump on any given day they work they're good reliable and will have you back on the road as soon as you clamp the battery cables and press start in your car

When I first got it I read the instructions and gave it a full charge that night and used it the next day to jump start my riding lawnmower and it started right up and I used it the same day to charge my cell phone.

Initial take: Looks good.. bought as replacement for a TACKLife T8 which mysteriously won't charge after 4 1/2 years. This item looked good based on reviews. Maybe I was hasty in ordering it but I was taken aback after I received the new item when I didn't see any USB power charger included in the package! (What?!) Their input is a USB B port and hence they are saving a couple of $s (plus packaging) by not including the charger. However, as the input is labeled as 3A (5V), that leaves me questioning who uses a 3A USB charging device? All I have is a 1A device and as expected, the charging was slow. I need it in my car as a backup, especially for any long road trips. You get what you pay for, huh?! (Only 4 stars since they didn't include a USB power charger.)

This is a handy tool to have and we have used it several times since we bought it for our lawnmowers that have been sitting up from winter. I may order 2 more to keep in the cars and one in the workshop. Easy to charge and small enough to store in small areas.

The instructions are easy to follow. The device arrives charged at 77% but I charged it some more up until 99% before using it. I placed it on the car battery making sure to connect the positive red first then the negative black. When I tried to turn the car on it started immediately. I went back out within 30 seconds and disconnected the device. I highly recommend this device, it is worth every single penny.

The 12v battery in my EV (Ionic5) suddenly died, nothing works without it. I ordered this because of the price and how it would arrive overnight. It worked perfectly, such a relief. It arrived already charged to 77%. I plugged it in and got it to 85% just to be sure (didn’t need to). Was very easy to hook up. The car started right away. One thing to remember, unhook right away and keep car on for 20-30 minutes for best result. I turned car off after only a minute and had to jump a second time.

El producto muy bueno , el transportista deja mucho que desear , deberían tratar de vender mejor en otras plataformas que le den más importancia a sus entregas ya que debido a la actitud de un tercero dejan de vender más .
