Will start a completely dead battery time and time again

I kept forgetting to turn off my inverter and my battery was dead a few times the week before the purchase

I have used it well over a dozen times and on many vehicle types and never remember to charge it

Used one time and it blew up

If this worked as it did the first time, I'd rate it 5 stars

The first time, it worked perfectly

The next time, the unit apparently did nothing...until I remembered to use the boost feature for really dead batteries, and then it worked like a champ

It was simple to use and it worked the very first time

so far I’m happy with it time will tell.

Works every time and is the easiest thing in the world to use.

Every time I use it, it works as well as any other method for getting a dead battery machine started

Worked well every time

It takes a long time to charge, but its still worth every penny.

I've used the Boost XL several times to jump other people's cars

I've used it 6 times recently and it only knocked one bar of charge off

Worked perfectly 3 times in a day

I have used my NOCO many time and it works great.

Have only had to use the GB50 once so far, but that one time was a life saver.

Even though I have emergency service, I wanted to be safe than sorry, not to mention don't want to waste time waiting for service

Works every time without hesitation

How many times have you been to the lake and killed your battery by accident

this unit is great when it works, within one year of using it 4 times the power button was not working

Used it 3 times, and it works flawlessly

NOCO Boost to the rescue for us time and again, be cause we have learned to keep it on board; no climbing up and down the stairs to get a battery charger/cords and all that mess

It has worked perfectly every time

n’t work at all
