AstroAI S8 Car Battery Jump Starter 1500A - Portable 12V Lithium Jump Box

I am so obsessed with this little thing! Car was in storage for 3 months and the battery was dead. I got this to try jumping it myself.INSTRUCTIONS: very simple. you attach red clamp, then black, wait for solid green light, press the “boost” button if the light is flashing, then try to start your car. *VERY IMPORTANT* I almost missed this in the instructions - after your car starts you must remove the device within 30 seconds or it can do damage. Also- although it arrived with full bars, I charged it before use as instructed and it continued to charge, stopping when it was actually full. So de

A couple days after I purchased this, my truck (07 Classic Chevy Silverado 1500) wouldn’t start because I had accidentally ran the battery down by leaving the doors open. It was SO easy to use and took literally like 20 seconds to start up my truck. Doesn’t take very long to charge either, and charges my phone great. Definitely buy this, it’s not that expensive relatively either.

Very strong. Will jump a complete dead dead dead battery. I love the boost feature. Well worth the money. Material is heavy duty and well made. Have had almost 2 years and still going strong. Charges well and holds charge well. Only down fall is can only boost jump about 3 to 4 times and takes battery jumper charge down fast. It's extremely easy to is and very portable.

When I took the AstroAI S8 out of the packaging, I looked at the unit and said to myself "you're kidding me this will never work but whatev's I'll give it a try". Boy was I wrong, this jump starter nails it every time.Early am, I took my dogs to the beach, returned, opened the lift gate, the pups jumped in and that was it, out of nowhere the battery died.....literally nothing was working. Got a jump and was back on the road. Back home, left it over night same thing. Luckily, I thought this would be a good time to buy a jump starter, cause you never know. I'd been toying with it for a while and

Brilliant, affordable jump starter. Easy to use, great travel size. Charges in a reasonable amount of time. This item was very useful during a troubling time with my car. I recommend this item, especially as a gift for a new driver.

Bought this reading the reviews with some hesitation. Ive been in need of an inexpensive jump pack for a while. So I got this one figuring that if it wasnt good I could return it. There are some negative reviews on this product for sure.I just used this to jump start my truck for the first time since I bought it. I have a 5.3 V8, when jumping off another vehicle, you have to let it charge up a bit first. Not the case for this jump pack. I hooked it up, hit the boost button, when and turned the ignition and the truck started up with no effort.Ive used this to charge phones and other portable us

I have an old F150 truck and a Honda Pilot with bad batteries. They always need to be jumped. Even when jumping with another truck, it can sometimes be difficult. This small Astro AI S8 1500A didn't just work once, but worked over 5x times and probably could have done more. Here is how I tested it.Started with the 1999 F150. Without the charger connected, the dashboard lights and bells would sound, but turning the key would not start the truck. In fact, the battery was so dead that I didn't even get a clicking noise. Connected S8 and it started like it had a brand-new, fully charged truck batt

Very happy with this jump starter. I bought it just in case and it already got me out of a jam when my car battery died. It started the car on the first try, no problem. It's compact and fits perfectly in the glove box. The charge holds up well, and it doubles as a power bank for my phone, which is a nice bonus. The built-in flashlight is handy for emergencies and the clamps feel sturdy and well made. For the price, it's absolutely worth having in the car for peace of mind. Highly recommend.
