Hate to be that guy but dollar store vibes are actually a step up for these things. Dollar stores sell those little plastic jumper cables that melt if you look at them wrong. A real battery jump pack from an auto parts store is like 40 bucks and it'll last years if you treat it right. That's not exactly premium gear but it's way better than the gas station specials. You get what you pay for but there's a difference between cheap and disposable.
