A lifesaver- should be a staple in everyone vehicle!!

Every car should have this!! I was gifted a 2012 Audi a4 and I’m so grateful for it, but as my mechanic says- “Audis are ouchies when it comes to parts and repairs.” My battery died in between work meetings and luckily my boyfriend came to jump me but I didn’t want to have this happen when he wasn’t around and feel powerless (especially since my triple a membership lapsed), so I bought this. It was so easy to use- especially when I was panicking and it was dark! Thank god it came charged because I almost cried when I read you have to charge it first (so check before bringing into your car!). All you need to do is put the cables into the device (size of a large cell phone), match them to the ports (Audis are such a pain but luckily I found them), and push the button to charge! I did have to do this four times based on the flashing light and testing my car to turn on, but it worked!! In all it took my less than 10 minutes in the cold and dark parking lot to start my car!! I’m so grateful for this little device and buying it for everyone for the holidays! Read more

Haven't needed to use it yet!

Picked this up because I needed a jump starter to keep in my second vehicle. Arrived nicely packed, it's slim and seems well built. Luckily I haven't needed it yet, so I can't say how well it works. It's nice it had a carry bag, but I kind of prefer a semi hard case. Otherwise I would buy again if needed. Read more

Easy way to jump your car

My car (Subaru Legacy) had been dead for over a month, so dead the electronic lock on the door would not open or any lights whatsoever. This slick lightweight Astro AI Mini Battery Jump Starter boosted my car easy peasy. Could not believe something not much bigger a than a paperback or heavier than an extra cell phone battery could start my car but it did. Super easy- I used the Boost since it was so dead but the car started immediately. I am super impressed. Read more

DO NOT BUY, battery is not listed for safety

This manufacturer's product posting is a lie, they specifically state they are US UL listed for safety compliance but there is nothing on the product itself indicating this is the case and they are not and they lied. The "CE" mark in the photo of the unitjust allows for manufacturer self-certification per European standards. The "FCC" mark just states, again per self stamping self regulation, that the unit doesn't give off radiation. Nothing on this equipment states it was certified by US standards for safety. They lied. I return. Read more
