5.0 out of 5 stars It's a very handy, economical, and useful tool!
Reviewed in the United States on October 1, 2024
This came with a 80% charge and before I had an opportunity to charge it, I needed it to start a vehicle. Not knowing whether or not it would work, I hooked it up to car battery, turned key, and car started right up. I'm really impressed! This is easy to use, compact, comes in nice sturdy storage container, and well worth the money. Would absolutely recommend purchase.

5.0 out of 5 stars Strong product and even better support team

Better or worse, I never write reviews unless I either love my experience or hate it. In this case, this product lives up to the description. Great size, power and charging time. The added USB port for phone/tablet, etc. is really a nice touch. The charging is super easy and fast. Really great product experience.

However the real reason I want to write this review is the service I received. We all have had our negative experiences with different service team. And in this case my only option was email only -- the worst! My jumper cables got pinched and the wire exposed -- these guys responded immediately and my new jumper cables arrived within 48 hours -- AMAZING. IMHO, this is how companies build lifetime customers. I will certainly go to them first in any [related] future buying journey.

Keep up the great work, I would highly recommend this company and product.

This thing rocks. Had a battery that was failing to keep charge and ordered this to cover me until I could get around to to replacing. Woke up to the battery very flat, like 9.8 volts, and was able get the car running in under a minute with this jump starter. With my car battery being so low, the jump starter dropped to 88%, but it charges quickly, back to 95% with the usb port as I drove to mechanic. My mechanic then quoted a ridiculous price for a new battery, so I jumped it once again to get to a AutoZone. The second jump only dropped the jump starter from 95 to 94%.

The jump starter works very well, there is a green flashing light that goes solid when it detects connection to battery. Then all it takes is a press of the ignition. The light and usb ports are a nice add. Also the battery has fast charging at 9 volt / 2amp if connected to a good power source. It seems durable and has good protections for overheating, over current, etc. Value is great for the features

5.0 out of 5 stars Excellent design. Excellent performance.

I deal with electronic equipment that needs to meet environmental performance standards. This thing is excellent. All electronic ports are properly sealed and covered. Solid construction, given this will get tossed around in a car. Beyond my expectations for a device of this cost. Case is protective, padded and well designed, and ready for my suv.

I drive deep into Utah southern desert every summer. My only anxiety is what would happen out there if my battery had gone dead in morning. Ten desert miles to nearest track where any other car would pass a few times a day. Desert sun. Charging cables were of little us out there. But I was careful. It never happened. Nonetheless every time I went out I worried. I could survive. Probably. This was what I needed as a security blanket.

It takes six to eight hours for first charge. Give it time. We see how long it holds a charge between storage periods. Or how long it lasts

Be aware this is a lithium battery. UN3480. Will charge a phone many times for sure. But never try to take this on a plane!!

An amazing small device with a big kick.

Arrived exactly as specified with 80% charge. Able to use immediately. Extremely simple to use. An included adapter to aid future recharging would have been nice - but otherwise very pleased with the product.

5.0 out of 5 stars Almost perfect
Reviewed in the United States on September 26, 2024
The good news is that this worked great on my 2005 mustang. It started it immediately and there was only 79% charge on it. I did try to charge it before I used it, but after an hour, it still said 79%. So, it's a slow charge. I gave 5 stars because the flaw isn't worth taking off a full star. The one disappointment is that you have to be careful with the plugs because they are made of cheap plastic. One end came loose when I applied it and I was able to snap it right back into place. Annoying, but it didn't break.
