Was nervous this wouldn’t get the job done but it did. Had my car in storage for 9 months and assumed the battery would be dead, which it was. Used this on the completely dead battery and it started instantly. I had to drive around a bit on short trips immediately after jumping it and obviously the battery hadn’t charged yet from the alternator but I whipped this thing out and it started my 2001 Toyota 4Runner 5 more times on one charge. For the price this thing is awesome.
Jump starts my vehicle sometimes works, sometimes drains from 100 to empty and does not even crank over engine. Wish I would have bought one of the bigger models with more cranking amps. If thinking of this get a bigger model if you have a v8 of any size.

Great little jumper, not expensive but works like it is.
Dealer cannot find what is wrong with my car battery draining but this little jumper has got me back up and on the road saving me time and money. Even though it sat in the car for 4 months it still had enough power to get me restarted today. Well worth the money.

Ehhhh,pass..
this little jump box is built, right it’s all right, but you get one jump out of it and then it completely dies. Well at least mine does too bad. The return window is over. If not, I would’ve returned it. Tried it once with the full battery battery dies charge it try it again battery dies, and won’t jump a car with that low battery.

PORTABLE AND EASY TO USE
I live in montana and this winter my battery was dying if I didn’t start it everyday and I live in a rural area therefore to have AAA come it could be the next day ! This fits in my glove box my car started immediately and I haven’t had to recharge the jump starter yet I do have a new battery now but these are so easy to use i recommend it for every driver. Teenagers and adults more than worth the money

Did Not Work – AstroAI S8 Jump Starter (Hyundai Tucson 2018 SE 2WD)
Disappointing Performance When It Was Needed Most – AstroAI S8 Car Battery Jump Starter I purchased the AstroAI S8 Car Battery Jump Starter, fully charged and ready for use. However, when I tried to use it to jumpstart my Hyundai Tucson 2018 SE 2WD, it didn’t work. Despite being fully charged, the device failed to provide enough power to start the car. I ended up calling roadside assistance, and with their kit, my car started on the first try. I was really disappointed as I had hoped this would be a reliable backup in an emergency. It didn’t live up to expectations when it mattered most. Pros: Compact and easy to store Fully charged when purchased 3 modes flashlight included Cons: Failed to start the car despite being fully charged Unreliable when needed in an emergency Lacked the necessary power for my 2018 Tucson Overall, I can’t recommend the AstroAI S8 Car Battery Jump Starter based on my experience. It didn’t perform as expected when it mattered the most.

It did what it was supposed to do so thumbs up
My car would not start and the key was stuck in it. There were no lights so naturally it had to be the battery. I quickly looked to see what was available and quickly. I found this battery pack, charged it and read all directions carefully. The first boost did turn on my radio, but my battery was just gone so it took 4 boosts to start it. My SUV is back to life and on the road again. This is portable, light weight and easy to store. It is easy to use and understand and has multiple uses with the light and battery bank.

This product is a handy lifesaver. This item especially works well for a rideshare driver that’s always on the road. The battery life and build quality are top notch. I would highly recommend this product
