I'm still searching for a good solid portable battery booster.
But truth is any pack with a lithium ion battery and has solid reviews take it.
Today already you shouldn't be paying more than fifty bucks for one.
You can find the solid one that has all the safety features if you plug it in the wrong order and can work up to V8 engines as well as multiple uses without needing to be recharged and 3/4 ports as well as flashlight.
The ability to work up to V8 engines means it has a nice cold cranking amp and battery power.
There's literally hundreds of them out there so if you see a good deal on one that's what you should grab more than just getting one because of Brand name.
