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.

Does not work
I charged this device but when I went to use it, it did not work. I sent a message to the supplier but have not heard back about replacing it.
John Stepp –
Within a week we needed it: did not disappoint
I was initially suspicious that something the length and width of my phone (But 3x deeper) would be able to jump start a car. Sure enough it absolutely does. I don’t know how they do it, but they do it, but they do it
Fern m. –

Didn’t hold the charge
I have to return it, not sure if product was damaged or hade other issues. I put it on the charger for 24 hours to charge, but it didn’t show no lines, like never been on charger.

Didn’t work
My car died last night and got this delivered by the morning. I fully charged it. Left it connected up until AAA arrived. But it didn’t jump start my car. My car wasn’t even fully dead. AAA got it started in less than a minute with their portable device.
Janet –

John Diaz –
It works great to jump a car
Small compact charger works well
Raneir Pollard –
Stopped working right away
The media could not be loaded. I never got to even use it to jump my car. I used it as a portable charger once and then when I went to recharge the battery, it would just not recharge. Total waste of money for me and tbh, I probably deserve for my item to be replaced but I didn’t notice the defective product until long after my return window. Just sucks

Kevin R. –
Six months later: worthless!
Bought in March 2024. AFter the major flooding in September 2024 – I needed to jump off a small “lawnmower style” piece of equipment. The machine cranked for 5 seconds… and the charger went from 100% (fully charged) – to 25% and won’t do anything else. Charged it again: SAME thing. Worthless DON’T RELY ON THIS IN AN EMERGENCY!!!

Great value
Bought one of this type of jumper when they came out at only 400 amps and used it a few times, but when one is needed it sure was handy and paid more for it. Now this one claims 1500 amps and so… Great price for capability.
Amazon Customer –
Reliable product
We’ve already used it 10+ times in a week. It charges quickly and holds a charge.

Works but not every time
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.

Great Jumper! Worked 1st Try!
Easiest thing I’ve ever done!

Easy to use when desperate
I’m a 60-yr-old, non-mechanically-inclined, single lady who only recently learned about these little portable jumper packs. After nearly suffering from hypothermia and frostbite when my car died in the grocery store parking lot on Christmas Eve, and trying to find an acquaintance to help, I knew I had to figure out a better way. I needed to help myself. This is how I’m going to try to do just that. This pack charges quickly – I use my phone charger plug and my wall socket. Instructions are short and clear. It’s super easy to use and you can’t make a mistake because the indicator lights guide you. Each attempt to start my mid-size car used about 25% of a full charge, so that means out in the wild, I will have 2 chances to get my car going again. Better than waiting around for a good samaritan in short supply, calling an expensive & busy tow truck, or finding an available acquaintance on a brutally cold winter holiday night.
Eric Wightman –
Worth the Price
Flash light and a power supply that can jump your dead car battery. They all do the same job. Everyone should have one in their trunk or under the seat.
Aleksandra Kapral –
Burning smell
So my car is still dead I got this and wanted to fully charge it before use and it started smelling like electrical fire. I unplugged it and now it’s dead like my car.
alwin t eugene –
Definitely does the job.
I was surprised how quickly it charged up. Connected to a totally dead Subaru battery. Pressed BOOST due to blinking green light. Took about 10 seconds of cranking then started right up. Still 75% charge left. Love it!
Nemecio Ramos –
Got the job done.
We have an older car, 2009 Mercury Milan, that we use as a spare. Something seems to be draining the battery where if we do not turn it on in 3-4 days it will not start. We would have to jump start it with another vehicle and jumper cables to bring it back to life. I have been wanting a jump starter pack for a while now and decided to try this one due to the low price. It did not disappoint. Arrived in good packaging and is so small that it can fit anywhere. The instructions were clear and easy. I charged it in the house then went out to give it a try. It worked on the 1st try! So much easier and more convenient than having to maneuver another vehicle in front of it to connect jumper cables. Saves time and stress. I do not know how this would work on a large car or truck. The car I used it on is a 4 cylinder smaller car and it worked perfectly for what I needed it for. Would recommend if you are not trying to spend $100s on a bigger jumper start pack.

Good purchase

Doesn’t stay charged long
Will be sending back does not stay charged long. It does work though.
Tony Smith –
Quality
Great
WB –
Works surprisingly well
My car battery lost it’s charge from lack of use and I needed a way to jump start it while the wife is at work. After charging this thing over night, I plugged it in and jumped my car on the first try. I was surprised that such a small jump starter could do the job but it worked great and I really like the small size because the units I’ve had in the past were always a pain to lug inside to recharge.
burro maluco –
Excellent product
Very usefull
Terence Harrington –
It is what they say
This jump box is exactly what I wanted great product and price
Waste of money –
Complete waste of money
I wish I could really give no stares because 1 star is truly pushing it. All though it does work, it’s Very cheap. The red part broke just after the first use and the black one just broke today. I am returning for a full refund no way in the world will I ever purchase this again.
R. Derr –
Works like a dream.
Works so well I am just sorry I just learned of it as it has been a week of pure frustration not having a car that will start and difficult to find someone to help give me a jump. Thank God for this little machine.
Nicole –
5 jumps on one charge
Works great. Literally jumped my son’s car faster than a car to car boost off! Hit the button and the alarm went off instantly! I also use it to charge my devises when I’m away from power.

Battery Life Saver!!

Frederica Bush –
Worked right out of the box!
I love this charger. Wish the clips were a little larger but it charged my Lincoln MKC right up!
Gabriel M. –
Excellent excellent product!!
Life saver!! Left the car parked for a week forgot to start during the week. Got this baby and started right up took 25% of the battery to start. Awesome product easy to use so much better than trying to get someone with jumper cables to help me out. Amazing!!
Christopher Ruggiero –
Saved my butt getting to work 👍
My car was recently having battery problems so I bought this over the weekend anticipating my car wouldn’t start when I needed to go to work. First day of the work week comes and my car isn’t starting. This got it started in under a minute. Useful and easy to use.
mark m. –
Wasn’t a good purchase
Wouldn’t turn my car battery over at all wouldn’t even make my hood light come on definitely would not recommend
Steven V. –
Life Saver!!!
Love this thing. It’s been a huge help when I was having car battery issues. Make sure to keep this in a cool place and out of the sun. I think there is a safety built in if it gets to hot because it won’t work. But I cooled it down and it started working again. You can usually get about 4-5 jumps (Honda Civic) before having to charge again.
Charles –
Junk, save your money
Battery was dead from the car sitting so long and barely cranked. So I bought this and connected it with full charge and literally did absolutely nothing. It will be going back, and I’ll buy something proven. I cannot believe they say this thing will work on a large V8. My car is a 3.0!
