I’ve got noco and Hulkman jump packs. They’ve helped a lot of people many a times. I wouldn’t push my Panasonic without it for sure. Small recommendation would be to “size up” whatever you’re trying to jump. Good to have extra jump capacity over what you need.
They’re likely “on sale” now too. Good time to buy if you’re in the market.
