This device is simple and has one job, to hold enough charge to jump start a car

I've jumped two different cars 3 times each (we were having temporary battery issues) and the cars started instantly each time and the JNC box still hasn't lost any charge

I used it once about 2 months after receiving it as a gift and otherwise it has sat in my truck except for the once a month or so where i bring it in and plug it in to make sure the charge is topped off.

Used it 5 times and now it no longer charge this was recommended by a friend but for me is a bad a experience and I ca

Safe, easy charge, portable

This worked perfectly, and when I checked the charging meter on the unit, I'd estimate there was enough charge left to jump the car 4 or 5 more times

and if I forget to charge it all I have to do is hook it to a vehicle that has a working alt and let the car run for 2 minutes and boom its charged more than enough to start a car

It seems like it just won't hold charge anymore

Not to heavy, takes a good charge and boosts a lot cars!!

This is by second one, I lost my first one after a ver 2 years of use with out problems, the charge last long on this battery pack, highly recommended

The charge it holds is incredible I would definitely recommend this to everyone as a backup in case their car needs a start up.

Okay, so I bought a smaller cheaper portable battery charge and it was terrible

This thing went strong (fully charged) for 3 1/2 hours

I have purchased several jump start products for my wife as her SUV has a problem losing charge from time to time.

Great at keeping a charge for days after being charged fully.

I've charged this thing once, living in florida and keeping it in the trunk of my car, it works everytime (used a total of 20 times).

works great charges fast.

works great charges fast.

Maintains enough charge for 3-4 boosts of an H7 850 CCA car battery.

This junk box will not hold a charge and the company will not refund my money.

Can hold a charge for months on end and can easily boost almost any vehicle with a dead battery

Well folks this is not my first JNC, but this units battery failed after 2 years, will not hold a decent charge.

It did not come with a cord to connect to a 110vAC wall outlet (the preferred charging method), and2

THE CHARGE A LONG TIME JUMPS STARTSPOWER IS GREAT.

Recently had issues with my battery not holding a charge and had to use it twice in a day and run my cb too

I wish I knew that the clamp was too big for the Mercedes positive charge

holds enough charge to jump several cars (or the same car over and over and over) before you need to plug it in

This is by second one, I lost my first one after a ver 2 years of use with out problems, the charge last long on this battery pack, highly recommended

Now I will just have to try disputing my CC charge....

My only problem is the volt meter for checking the charge has quit working after 3 weeks.

Works every time with a good charge on it

Dependable jump/charge.

It does not hold a charge anymore so it doesn’t work anymore.

But definitely reliable if charges properly.

When I purchased the product I thought it would jump the car first try after a correct full charge.

Came already charged, works as it should!

Works well keeps a good charge a little heave for my wife but but was designed to crank not carry

b/c sometimes a battery can get so dirty you can't see the difference between Positive and Negative in the dark and could explode the battery).My car totally did not start like this.

My car dies on me a

Worked as it was supposed to.

I've used these blue Clore Automotive jump packs extensively in a commercial setting (jumpstarting a number of V8 vans and other vehicles that were totally dead in rapid succession) as well as for the occasional jump start of my personal car.
