Please see comments from Dec offering.
Overall the review and general opinions are this is a stay away item.
Your mileage my vary, but if I have to have a boost unit ready on that cold dreary day my battery dies, I don’t want something that “might” work.
I bought the GB20 in Dec 18…charged it and forgot about it. Last month a friend had his truck die in a location where it couldn’t be jumped…he took my NOCO Starter and even though it displayed 50% charge, he reported it started his 6-cyl truck easily. Then he didn’t return the jump starter.
I’m actually going to buy the 50 here today to replace.
I have 3 of the gb40s and they have been fantastic. Used on suburban, trailblazer, and LeSabre vehicles with no problems. We’ve started jetskis 4 wheelers and riding mowers too. I started with one to see and now have em for all the cars. I can’t speak to this particular model but this brand is pretty highly regarded for these.
- never loan anything you can’t afford to replace
- someone who owes you something can never borrow from you again.
also gospel but not applicable here:
3) Never loan money to someone who smokes or plays the lottery
4) Never loan out a snowblower (it will come back broken every time).
These things need to be set up like house plug-in emergency flashlights… connected to the car so they stay charged until you need it. Every time I’ve ever needed the jump box I have the stupid thing’s been dead, even after replacing a bad battery. Needs a trickle charger built in so you can plug it into a socket and leave it there until the car thorks, then unplug, take up front and jump it.
