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.

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.

not for large SUVs

It only charges a "Large SUV" once at full charge. Anything after that its only good for the lights and air pump. Learned the hard way, as Im use to my Noco giving a good number of jumps before dying. Not worth the time or money.

This unit is designed to be used when fully charged. Under charging the unit will result in decreased performance. It is recommended to charge this unit every 30-90 days to make sure the unit is fully charged in case of emergency.

Long lasting and very satisfied

I purchased a unit just like this new one I just purchased again. The original one lasted me 5+ years. I used it mantvtimes to jump start my 24hp lawn mower, my 15vyear old cars when needed, and inflated many PU truck, car, lawnmower, and bike tires. The auto shut-off works great and the large battery allows you to check n fill all 4 car tires in one charge.

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

Peace of mind

This jump start/ air compressor has saved my butt numerous times. So worth the cost. Knowing it is with me brings peace of mind.

I don't like the fact that the digital tire gage hasn't read numbers since the first year and the battery died in the first Year I owned it

Terrible product. Went through 2 of these.both times used once. Won't air up a single tire without burning the compresser up.

Efficient

[This review was collected as part of a promotion.] Works amazingly when you need your car jumped I'm definitely keeping this in my vehicle and recommending it to friends and family because it could be a lifesaver
