AstroAI S8 Air Jump Starter with Air Compressor,3000A Peak Car Battery Jump Starter Portable (9.0 Gas/6.5L Diesel) with 150PSI Cordless Auto-Shutoff Tire Inflator, 12V Battery Charger Booster(Yellow)

My expectations for performance and durabilityhave lowered in the course of trying many new Chinese trinkets and devices this last year. So I was pleasantly surprised by this jumper which I bought as a replacement for a good one that was stolen (Is anyone noticing that theft in America is on the rise - very fashionable these days it seems) I should point out that this good jumper that had to be replaced I purchased months ago, before these Trump tariffs hit. So everything now seems like less value for the price, at least for a while...but, I digress, and going back to my review and to the point. Notwithstanding the price increase, this jumper has decent value, operating better than it looks and feels - It's kinda of plasticy and lightweight but very effective functionally speaking. Normally I would give it 4 stars for the couple of shortcomings like for example to few shock absorbing rubber bumpers to stabilize the unit while it jitter dances during air compression and an air tube that's too short for practical use - I'll look the other way in this time because the damn thing works pretty well and is better than it looks. So feeling as generous as I am I give it five stars today, whereas yesterday and tomorrow might give a different result.

After buying our first and it working so well, we've bought three more of these for our cars and one as a gift. We've used them for jumping a car and filling a tire. Both worked well. Periodically, when we think about it, we'll bring them in and recharge them and we recharge after every use. A friend's car had been towed and stored while in and out of the hospital. Before that, it had only been driven a few times over the previous year. When we went to pick it up the battery was so completely dead and this seemed not to work. There is a special thing to do in this case, which is why it was great we kept the book in the bag. We followed the directions and it worked great and got the van running enough to get it back to their apartment. It was also raining in torrents during the whole ordeal. We ordered one for our friend.

The jump-start feature I have not actually used, but I have no reason to think it won't work. Astro AI makes nice products, so I'm sure it will work. The air compressor I have used and it works as it should, very nice indeed. HOWEVER there is one drawback to this compressor. It has a few preset modes, e.g., car, motorcycle. bicycle, ball. You have to select a mode, then the PSI available are in a limited range for that type of tire. You can't just set this to any number PSI you want. For eample my snow blower tires need 19 PSI. It is not possible to set it for that number. I have to set it for a much higher number and watch the pressure on the screen till it gets close to 19,is then stop it. Then reattach it to see what the psi is or use a gauge and either add more or take some air out. It's not the end of the world, but it is a bit frustrating. Why not just allow us to put in the PSI we need. WHo needs those preset modes anyway??

Used it on the first day it arrived. I had a battery I felt was getting finicky and at night when I was ready to leave the house my car wouldn't turn. I didnt have time to charge it right away but charged it on a fast cable for 15 minutes and it was able to boost my battery enough to start my car. I like that the air compressor parts are all attached, we'll see about the length of the cord though. Other than that seems good!

Easy to use! I haven't needed to use the jumper cables yet, thankfully, but have filled my car's tires several times and it's super easy. However if the valve is at the top of the tire, you may need something to set the unit on while it fills because it does get kind of hot and the hose is not very long. Nice little addition to road trip gear!

Awful, don't waste time or money. This did not crank my car.

I used it to put air in my car tire and it was almost flat and it filled up faster than I expected. I haven’t used it to jump off a vehicle yet.

These are great. I have given three away as gifts ( two were specifically requested)
