Opinions about this product were divided in such a proportion among the buyers.
Works beautifully charging the dead battery on my Acura RDX! The car sat with the dead battery for at least a week before I used this charger. I was a little amazed and very impressed! Hands down the best $100 I’ve spent in quite some time.

Everyone should have this tool in their auto/truck!!
Everyone should have this tool in their auto/truck!! An exceptional tool to have if you need a jump and there are no other automobiles or service stations to be found. This was recommended by a trusted auto service technician. He was 100% on the money. Not only have I been able to jump my auto, but have been able to help others in need. Glad I made this purchase.

Works great!
My car battery was absolutely dead. I had to use the “boost” feature. My car started up with no problems. This little device is worth every penny. I am so pleased with this purchase.

Must have
It’s better than risking a jumpstart from another battery. My vehicle is too fragile to jump others in need. And this unit works well. Small and compact

Wow! What a help!
My husband’s car had a flat 12v battery yesterday morning and I ordered this device from Amazon around 11am. By 7pm it had arrived and we used it this morning to bump start the car – super easy to use, good small instruction manual. When it first arrived I made sure to charge it up to 100% (it came 75% charged which would have been just fine but I wanted to be on the safe side.) It took literaly 30 seconds to check the battery, which was low, and to press the “boost” button. This started the car straightaway and enabled him to take our son to school. This is such a useful tool because you never know when you will need it and there may not be another car around to assist with a charge. We will see how the battery is this afternoon while I work out buying a replacement 12v battery!

Nicely designed but best for light duty boosting
Well designed and made. It worked for me with a mildly weak battery but for a battery very low and in the cold it didn’t have enough push. I think it’s great to have for any household in case of a power outage. Lots of juice for charging devices. Glad I picked this item up on sale. I wouldn’t want to pay top dollar for what it can do.

Nice Car Battery Jumper / Missing Parts
Purchased this AstroAI S8 Ultra Car Battery Jump Starter recently. I honestly have not needed to use this yet, thankfully. Packaging was nice but incomplete. Wall charging adapter was missing! This was a big disappointment for me personally. Contacted company regarding this issue. Will see how customer support will address this issue. Will update on usage and customer support response.
