Was nervous this wouldn’t get the job done but it did. Had my car in storage for 9 months and assumed the battery would be dead, which it was. Used this on the completely dead battery and it started instantly. I had to drive around a bit on short trips immediately after jumping it and obviously the battery hadn’t charged yet from the alternator but I whipped this thing out and it started my 2001 Toyota 4Runner 5 more times on one charge. For the price this thing is awesome.
Jump starts my vehicle sometimes works, sometimes drains from 100 to empty and does not even crank over engine. Wish I would have bought one of the bigger models with more cranking amps. If thinking of this get a bigger model if you have a v8 of any size.

everything was great on this order
Gregory Carter –
Seriously Everyone needs one!
This little thing is a Beast! Started a car in -0 degree temps, it will get the job done.
Travis Richeson –
Portable and works!
This little thing could fit in a decent sized pocket and works like a charm.
Jim Franklin –
Great for the price
These things are awesome and a life saver. Everyone should have one on their car.

Get the job done… Eventually
I was really hopeful about this after reading many reviews about how fast this would jump start their car. Ive used on two different vehicles and they have both started… Eventually. The first I had to keep it hooked up for about half an hour and after trying to start the car several times, it just drained the battery pack and didn’t start. I had to recharge the battery pack and then go try again. After keeping it hooked up for another 15ish minutes it finally started. For the second vehicle I left it hooked up for about 10 minutes before even trying to start. It didn’t work the first time either. Had to keep it hooked up for another at least 10 minutes and finally got started. Both times I tried the boost button several times. So even tho it did get me jump started, I can’t say it’s a quick 30 second jp like many have stated.

Everyone should own one
Legitimately one of the best purchases I’ve ever made. Works great, holds a charge, durable

Great product
Light weight easy to use. Stays charged a long time.
Amazon Customer –
Highly Use
Get it. Works as advertised. Have one for the car and touring motorcycle. Now this won’t help a totally dead , been jumped too much battery. But for a quick cold star or a battery that’s been sitting for a few days maybe a few months. This is your ticket. Not to mention its usefulness charging your small electronics
nadia –
Very good
I love it, same day delivery, good quality and easy to use
Curmudgeonly Doc –
Handy and compact emergency device.
Haven’t had a chance to use it…hopefully won’t. Very compact and likely much safer and easier than standard jumper cables, and doesn’t require another vehicle! Also doubles as compact power bank. Will be living in my car (except when being charged itself).

Must have at all times!
This product recently saved me from a parking ticket; on street sweeping day my battery was dead. I hooked this jump starter up and was able to move the car across the street and called roadside assistance for a new battery. This compact jump starter is so much more efficient than the ole’ jumper cables and having to find someone to give a jump! Just make sure it’s always charged and ready to use!

Drained my cars battery more
No matter what I tried after following instructions, it never worked. It actually drained the cars battery more.

Can only jump dead battery at 100% charge
I have used this AI box to jump a car twice now. The first time it took three tries to get it to jump. The second time it worked the first time that I jumped it. Today, the third time, it would not jump it. I come to find out that if it is not charged to 100%, it will not jump a dead car battery. I also didn’t realize that you can only charge this jumper from a USB cable. You cannot charge it from another vehicles’ battery. This is not very good. So I am giving this three stars. I have used another jumper that does not have a battery in it. It cost a little more, but it will charge off another battery and off the 12 V port in a vehicle within two minutes. That one DID jump the car today.
Christel –
Perfect size and quality
The build quality is great, perfect size not to big to pack around, versatility is good, heat level is good. The power and usb have been doing great also.

Battery charger
To jump my grandson’s suv. Was easy to use and started right away. Pricing was decent.
Amazon Customer –
Garbage
Absolute garbage. The first time I needed it it wouldn’t work and it was the day after the window closed to return it. Very disappointed
Jen D. –
Bought two and neither worked
Bought two of these as gifts. One worked for one jump start and after wouldn’t charge again. The other never would charge. Disappointing. I have had great experience with other brands of jump starters for my car and boat. I’ll avoid this brand in the future.
redrock435 –
Got to have one of these!
It’s a must to have one of these in your car. Can’t go wrong

Does Not work
This item does not jack start vehicle. I just purchased this on December 31,2024 and it did not need to use it until yesterday 2/16/25. My explorers battery was dead and I was trying to use this jump pack to start. Does not work my jump pack was completely charged. Now I can’t return it because I missed the date of 1/31/25. Waste of money.

Good product
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.
MB –
Compact and tough
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.

Tested – Started my car without the main battery attached.
I tested this unit by completely detaching the normal battery in my 2.0L Mazda 3. I attached the fully charged Astro AI 8 and, following the instructions, I pressed the Boost button and started my car. The Astro AI used 25% of its power so it should be good for two or three starts without recharging. I’m very pleased with the ease of use and compact size of the unit.
Kemar –
Good battery life
Jump stared my car a few times & two other cars. There’s still four bars in it
Happy Lady –
great product
My SUV was completely dead and it jump-started it without a problem.
Rseneff –
too soon to tell
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.

Got me home !
This “Jump Starter” got me out of a pinch in a way it was NOT designed to do.. A couple days ago, I was about 100mi from home with my old (2004) Chevy pickup when the “BATT” light came on, and my driver’s display told me “BATTERY NOT CHARGING”. I shut down all non-essential electrical components, and headed straight for home. About 1/2 way there, the turn signals stopped working, and I knew the battery was getting low.. So – without turning off the engine – I hooked up this “Jump Starter” to my low battery, and made it HOME OK ! I now have a new alternator (also from Amazon)..

Car charger
My husband got this for me, for Christmas. I changed it and put it in my trunk. Yesterday my car battery was dead. I got this charger out and it started my car immediately. My husband was so impressed we ordered another for his car. I couldn’t be happier with this charger and highly recommend.
Ivan –
Better than jumper cables
Directions were clear with great illustrations noting the place for each function. The Jumper Box came with between 50 and 75% charge. It took about a hour to completely charge. My Saturn battery would not even turn over. I hooked up the Jumper Box up to my Saturn battery and it turned over immediately. Also, this Box tells you if you have correctly hooked up to the correct battery terminals or if your battery can’t be charged. Please note. While the item comes with a cable to initially charge their Jumper Box to 100 %, it does not come with a USB-A charger block. You must have one from another source. However since the input to the Jumper Box is USB-C, I assume you could use your own a cable with USB-C on both ends and a USB-C Charger block.

Economical, compact, and handy
It works! I have a truck that has a hard time holding a charge occasionally in freezing weather and was able to use this today. I appreciate how compact it is, that they included two mini jumpers cables, and apparently they offer a 2 year warranty.
T. Jewell –
My car started immediately on the first try!
The jump starter was delivered quickly and in good condition, and it worked great to jump my battery after my car had been sitting in cold weather for several days. The starter was already at a 75% charge when it arrived. The only minor issue is that the nylon bag it comes in was not sewn very well around the drawstring, so a lot of frayed threads got caught on the device when pulling it in and out of the bag.
Mine didn’t even last 1 year –
Vehicle charger
Not happy with. It at all. Would like to return it
TheLodger –
Great power storage and charge
Have used for over 6 months now. Long lasting charge, charges quickly, especially through the output USB option. It does seem to take awhile to charge itself though, but probably because it lasts so long.

Battery jump start
Was exactly as advertised. Have not had the opportunity to use this item yet but hopefully it will work as advertised
Christian –
Great deal on a lithium jump starter!
This jump starter is a fantastic deal! I was actually standing in Harbor Freight with one in my hand and thought I should just check Amazon and found this it was actually twice the power and half the price! I have a random issue with my automatic back door in my car and it will occasionally not completely latch and it will cause the marker lights to come on after I walk away killing the battery, this thing takes about 30 seconds to hook up and I’m on my way! Great product would 100% buy again!
Diana sorenson –
Great
Product is small and compact great to have in the vehicle. The price was pretty reasonable too, so I think it was a win.
JB –
Great value, Super easy to use
This came next day when we needed it most. We had let the car sit too long and it drained the battery. We park our car in a parking garage so a tow truck jump would have been a real hassle. Came partly charged, so within a couple hours, we jumped the car and were on our way. We keep it in the car charged and ready in case we need it again. Highly recommend. And at the price, good to always have something like this on hand.
Gabriel –
Did the job
My 2013 Nissan altima died in the garage. Didn’t want to push it out to jump it, so ordered this. Started on the third try. Very easy to use if you read the instructions.
