âââââ Lifesaver! Especially if youâre often on your own.
I bought this jump starter in October 2024 after a frustrating experience where my car battery died while I was grocery shopping. I had accidentally left the headlights on, and by the time I got back — around 9 p.m. my car wouldnât start, and I had no one to call for help. That night made me realize how important it is to be self-reliant in such moments.Since Iâve been through that more than once, and after paying way too much to roadside services for a simple jumpstart (literally takes 2 minutes with the right tool!), I decided to invest in one of my own. I came across this model after seeing a mechanic use something similar and I am so glad I did.This jump starter has already saved me twice. Itâs compact, easy to use, charges fast, and does the job flawlessly. The instructions are clear, and the fact that I can now handle a dead battery all by myself feels so empowering. As a woman who often drives alone, this tool gives me peace of mind and independence.Iâd strongly recommend this to anyone — especially women or folks who donât want to rely on someone else in emergencies. Keep it in your car, you never know when youâll need it. Truly a must-have for every vehicle!

Easy to use and put away charges up fast.
So far Iâve have not used it but seems very well made and sturdy and itâs been holding the charge 100 percent for over 8 months now. Sits in my car and stills works just like new. Iâve only turned it on and checked it out. Has not performed a jump start but Iâm 100 percent it will definitely jump so many cars n heavy trucks. Iâve had others in the past with less than half of this power so Iâm not worried about that part. Everyone should own this and a tire inflator seriously donât get stranded at night or anywhere for that matter. Itâs so affordable for 100 or less you can have both a jumper n a tire inflator.

I appreciate the clear LCD display that shows battery status and other info â very user-friendly. The built-in USB ports come in handy for charging phones or other devices during emergencies, and the LED light is bright enough to work by in low light situations. The included storage case keeps everything organized and protected. Overall, itâs reliable and easy to use, giving me peace of mind on the road. Would definitely recommend for anyone wanting a portable and versatile jump starter.

Must Have
I have not needed to use it yet.It seems well made and comes with a nice storage zippered container. The instructions are clear and easy to understand. It was partly charged on arrival, so I charged it fully. I keep in the vehicle, because…The price was right for a bit of emergency insurance.

Seems well built but no charging block
Ok, I am giving this 5 stars at the moment with the disclaimer that I have not used it yet. I will say that the flashlight is bright. And the build quality seems very good. It comes with a nice heavy semi-hard case. It does not come with a charging block though. Which leads to the remainder of my review that will hopefully help others if they have slow charging issues. I will update this review and stars once I get to use it to jump a vehicle.I am a question I asked about which charging blocks will work with this and charge at 9 volts and 2 amps. None of my charging blocks I already had would work at 9 volts. I got a few answers and only one sort of answering the question. But I was surprised to get a message later that evening from the seller giving me a suggestion of which block to use for 9 volt 2 amp charging (that the device manual suggests using over 5v). I hope this information helps others.The seller suggested this one:https://www.amazon.com/dp/B07QJBKRSV?th=1I did not try it because I ordered this one before their response and it is charging at 9 volts.https://www.amazon.com/dp/B09NY3RSJ2And it is charging much faster than the 5 volt charging block I was trying. I definitely suggest trying a 9 volt capable block if your charging is painfully slow. The charge on my jumpbox has went up 6% in less time than it went up 1% with a charging block that was outputting 5 volts.Also note that the display does tell you what voltage it is charging at. It will either say “5.0V 2.0A” or “9.0V 2.0A”.I hope this information helps others with slow charging issues. And kudos to the seller. Thanks for the quick answer.
