Awesome

Best thing works perfect It has so many functions and it’s so very useful. I was fortunate enough to get it when it was on sale for around $56 and I bought two of them. I wish I had bought more and make great gifts for loved ones you can charge your phone , you can jump your car off you can put air in your tires, etc. there’s just so many things that this machine can do.

Good but not compact

The unit works very well and is quite powerful, but I found it much heavier and more cumbersome than I expected. Based on the photos, I thought it would be more light and compact. It gets the job done, but I highly recommend checking the dimensions and weight before buying to ensure it fits your needs.

Disappointed

For whatevrr reason the jumpbox I have has never been able to jumpstart any car I've ever tried to jump. The compressor and USB ports are fine, but that about it.

Sad and disappointing

Thought this would be a great gift for my son but turns out it won’t hold a charge and took over 30 mins to barely inflate a 40psi tire, which in turn drained the battery. This was highly disappointing considering the price. Will stick with the better yellow and black name brand for better quality

Dumb change!

Latest model needs its own special power cord to recharge. Cannot simply plug in using a grounded cord like previous models. It’s ridiculous that I have to tie s baggie containing special cord to it so I have it when needed. Totally useless design change from older models.

Reliable

I have used mine for 5 years now and it is still working great ! It has been used to jump car batteries ( too many times to count ) inflate my tires and even charge my phone ! Paid for itself a couple times over, worth having and would recommend this item.
