   The S500 Car Battery Jump Starter has been an absolute lifesaver for me, especially when dealing with my old, unreliable car battery. This portable powerhouse, with its 2500A peak current, is capable of jump-starting up to 8.0L gas and 7.0L diesel engines, making it a must-have for any vehicle owner. What truly sets the S500 apart is its quick-charge feature and the smart jumper cable system. The larger LCD display provides clear, easy-to-read information, which is incredibly helpful during those stressful moments when your car won’t start. The 3-in-1 light is a brilliant addition, offering a bright flashlight, SOS signal, and strobe light for emergencies—adding a layer of safety and convenience. Having this jump starter in my car has given me peace of mind, especially on those cold mornings when my old battery decides to give up. With the S500, I can quickly and confidently jump-start my car without waiting for roadside assistance or relying on the kindness of strangers. It’s compact, portable, and incredibly easy to use, making it perfect for anyone who drives. If you have an old battery like mine or just want to be prepared for any unexpected situations on the road, the S500 Car Battery Jump Starter is an essential tool. It’s more than just a jumper box; it’s a reliable companion that ensures you’re never stranded, providing the power and reassurance needed to keep you moving.

   I couldn’t be happier with the S400 Car Battery Jump Starter! It’s a powerful little device that packs a serious punch. I’ve used it to jump-start both my truck and my wife’s sedan, and it worked flawlessly every time. The 1500A peak current is more than enough to get the job done, even for larger engines.
   The 2-inch LCD display is a fantastic feature—it clearly shows the battery status, so I always know how much charge I have left. The built-in 3-in-1 light is incredibly handy, especially when I had to use it at night. Whether you need a flashlight, strobe, or SOS signal, this thing has you covered.
   The best part? It’s so compact that it fits easily in my glove box, yet powerful enough to give me peace of mind whenever I’m on the road. If you’re looking for a reliable jump starter that’s easy to use and packed with useful features, the S400 is definitely the way to go!

   Never really got it to work when I needed it. I’ve bought other “overseas” chargers before and most work when needed…not this one. Says 99% but nothing is there to even turn the interior lights on let along call for the big amps when needed. You can watch the % drop slowly for no reason and half the time I “tried” it to test it down the road it was dead. Of course since this is the type of thing you don’t know it doesn’t work until it fails when you need it…the window has closed for an exchange.

   I only had to used this once so far. I can’t help other people jumpstart cars due to my car is on the newer side and can mess up the electronics in the car. I was able to help a friend out with this when their battery was dead. It was easy and quick to attach to the dead battery. Within a few minutes, the car started up and they were able to drive off.

   Works to jump dead vehicle battery with no problem after charging. A dead battery will reduce remaining unit power by over 50% so definitely recommend recharge of unit before use later. Turned over a 6 ltr engine with only being on the battery less than 25 seconds. Would absolutely recommend to others. Unit could be a little improved by increasing alligator bite & cable length.

   We had some people over to the house and they left their headlights on. Needed a jump, and I had just received this jump pack the day before and charged it up. Connected it to the battery, turned it on, and their car started immediately. Only used 3% power too, and I didn’t have to move my car around or mess with jumper cables. Love that it has a large digital display on top so you know the charge level precisely, and it has 3 USB ports (USB-A 2A, USB-A 3A, USB-C). Bought 4 more so all family members can have one in their car instead of jumper cables (and this is smaller too!).

   It’s important not to use jumper cables to jump another car anymore because you can dry the computer in either vehicle, so get one of these jump packs. They’re easier to use anyway, because you don’t have to worry about lining the 2 cars up so jumper cables reach, or pushing a car out of a garage that has a dead battery, etc. Just hook it up and go!

   As I said in the video this product is well worth the price. It is convenient for most situations. The online sad part is it does not come with the heavy duty charge block to charge the battery. I like how it is portable, doesn’t take up much space , and is long lasting. I have had it for a couple months and it’s still ready to go. It’s easy to use and all around handy to have at a moments time.
