I bought this 3 days ago. Primarily to charge my cell phone over night when I was at a training class at a Boy Scout Camp. I figured it would keep a charge for days before having to recharge the unit. NOPE. It was completely dead before morning with just a cell phone plugged into it. Highly disappointed. Which means I have to charge the unit during the day so I can charge my phone at night.

I have been having this for about 6 months now, I have used it to start lawn mowers, & trucks I used it to start a truck that was so dead that the instrument panel lights would not come on. The reason that I gave it 4 stars is that it is a 400 Amp booster, The GB20 is a 500 Amp booster, & the GB40 is a 1000 Amp booster. The GB40 is only $10 more than this one on the NOCO website.
