Charged the two I got last night. They come in a nice case.
Medium weight!

Will test the voltage in the morning! Not sure if I have ever done that with a meter! Has anyone tested a jump starter with a meter?

I suspect that they all are migrating to different types of lithium batteries.

My old one was sweasting sticky toxic stuff even though it is parked in the garage 90% of the time. 2 years old.

Store these in the house and grab them when you walk out the door.

Also if your car is parked in the sun all day get a cooler or take it inside.

You store these in your house and remember to grab before you go? Damn. No way I'm keeping these in the car.. I'll replace them every few years if I need to. Cheap insurance for not getting stranded
