  • ULTRA POWERFUL BOOST - The smart boost mode automatically detects the battery's voltage. When the voltage is less than 9 V, the indicator flashes green; this unlocks the "BOOST" button, which can be pressed to start fully-drained batteries.

  • Great Product
Color: Orange
Great product. It's small, convenient and doesn't take up much space in the car. The light is bright, and charge is fast and well maintained.

  • A Must-Have for Every Car Owner!
Color: Orange
This jump starter is an absolute lifesaver! Compact yet powerful, it quickly brought my car battery back to life without any hassle. The build quality feels solid, and the additional features like USB charging and a flashlight make it even more useful. It’s definitely worth the investment—having this in your car gives peace of mind in case of emergencies. Highly recommended for every driver! ... show more

  • Good product
Color: Orange
My friend convinced me to get one of these. He has this same model and brought it over one day when he needed me to load test the battery and alternator in his daughter's car. The car would not restart when he turned it off. The short of the story is we figured out it was the battery. When he needed to jump start the car to go get a battery, he pulled out this Astro AI S8 jump starter and it started the car with no problems. It was very easy to use. So I got myself one after he walked me through how to use his. Highly recommend. I think the biggest upside to this is never needing to stress your own car battery to start someone else's car. ... show more

  • too soon to tell
Color: Orange
It appears to be a good sturdy unit. But the proof will be if it jumps my bike. I do see that the cables are a bit short, ok if working on a car, but motorcycle batteries are a different breed. So, for now I give it a 4 based on these comments.

  • Buy one
Color: Orange
Small, compact but powerful enough. Very handy, easy to charge and easy to use. Much better than lugging an extension cord and charger to the vehicle.

  • Compact and tough
Color: Orange
This little charger packs a punch for the price. Works well. The jumper cables are a bit short but they work well for my application. Highly recommend this product. Similar name brand products are 4 or 5 times as expensive. Even if this tool last half as long as those do, it’s still a great value for the versatility. ... show more

  • Works GREAT!!
Color: Red
The day it arrived I charged it with my MacBook Pro USB-c charger for less than an hour until fully charged. An hour later my car would not start. I hooked ip up (VERY easy and SAFE), let it charge for 2-3 min, and the car started as soon as I pushed the start button. Charger showed it had dropped from 5 to 3 bars, which I assume means it is good for two starts before needing a recharge, but it is a tiny little device (as compared to long jumper cables and a 12 volt car battery), and since most cars today include USB outlets I suspect it can be charged while driving. It takes little room to keep in trunk and could be a lifesaver--for me or just helping another driver. HIGHLY RECOMMEND! ... show more

  • Great little jumper, not expensive but works like it is.
Color: Orange
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.
