Saw this one at Costco at $59. Anybody had experience with it?
These will NOT start a dead battery in a car...... It will add a "boost" to a battery that is not capable of turning over a car but has some power left in the battery.
Try it and if you don't like it return it! Costco is known for EZ returns.
Don't actually expect it to work as advertised. Especially if you have a V8.

How long do these things hold a charge?
I just bought one at Costco and hopefully it'll start my generator. I gave up on buying these small lead acid batteries. They seem to go bad about every year.
Does anyone know if you can use these without an existing battery in the circuit? I don't see why not but haven't tried yet.
Theres videos all over Youtube of guys unhooking the car battery cables and jumpstarting the car straight off the jumpstarter back, bypassing the battery.
It might not work with every jump starter but it is possible with some.
One thing you have to be careful with them. My snap on dealer was selling some and there was a major recall on them as they were catching fire when chargeing. The one I have is made by antigravity battery's who has been a leader in the tech (they also make lithium battery's for cars and motorcycles)
So just be aware of the cheaper ones and monitor them when charging.

Most blow when they're left connected to a running car.
Snapon isn't carrying antigravity and they stopped fixing them. Snapon came out with their own for the same price
Mine stopped charging idk why. I took the credit and brought a battery charger instead
Snap on was carrying a off brand and those are are the ones that has a major recall. And they would catch fire when charging not when connected to the car.
I call BS on this one, bro. I would love to see a video of this.Started my Dodge Ram 3500 with a cummin Diesel is -20C
the truck has 2 batteries i tried my charger in start mode 100amp and half full snap-on booster pac at the same time on each battery
the charger was on for 30min. i left work to get something i come back charger is put away im like wtf. so i say lets try that silly booster thing. put it on got in the truck started right up. I was in shock myself![]()

When it's completely dead to the point where your headlights won't come on, it's not going to work
Cars In general. I turned over a 4 cyl once or twice that had a bad battery, but I didn't count on it. It's a good tool to have you should be fine keeping one in the car
Mine, not sure how to make hot, done a few days ago. Battery completely disconnected on a 2007 Toyota Tundra 5.7 V8 in 34 degrees, truck had not been run all day. Took me a few attempts trying to keep a good connection on the positive leads as there are 2 I had to stack and keep a good connection on but once I got them tight together no problem. If i had a 100% dead battery where I did not have to disconnect the leads from the terminal it would have been a no brainer.
