The second time in rigid temps, no dice.

Tried the first time and it did not work

Great product to have on hand used it 3 times already and time saver!

Worked fine the few times I used it over the last 24 months.

Used it 3 times and then just die, and will not charge anymore

It has worked one time and left me stranded at least five times.

The GB70 is a good two times larger than the GB40.

Most times the junky usb plug fails to make contact or looses contact.

It worked great MULTIPLE times over the 2.5 years that I owned it

I had to use this one time but fortunate it wasn't the battery that was the

This thing works great, used it a few times already and still on the same charge without any problem, downside, the light is on the other side of the cable leads.

Don't waste your time and money on other brands like I did.

But the Noco Boost brings it back to life every time.

Works great, I’ve used it multiple times and works perfectly!!

After owning several jump boxes over the years i found that every time I needed them they had lost charge and wouldn't do the job I bought it

I’ve used it three times and it worked as advertised

However, the last time I attempted to use it, it was completed dead (only a few months since the last full charge) and, more importantly, it now will not hold any sort of charge.

First time I went to use it on my Land Cruiser (left door ajar for 5 days and dome light drained down the battery) and the GB70 would not turn the engine over fully, got maybe one turn on the engine then nothing.

It has a hard time doing 2.0's

maybe like 10 times before the battery runs out!

The NOCO GB70 worked flawlessly every time I needed it to

My car had a hard time with a cold Colorado start (2012 VW), hooked this up fully charged and it started right up!

This thing looks fancy and it gives you confidence but from my experience, it failed miserably at the most critical time

and it wouldn't start, thinking this would be the perfect time to use a jump

My ranger dies all the time, anytime it's cold really if not left on a battery tender, even with an odyssey battery
