I got the original Storm2 battery on the first crowdfunded effort which was a bit rough, not gonna lie. But it's a GREAT portable battery (and right at the limit of what you can fly with). . I got the slim battery that route and it was just a standard Amazon experience. I love their batteries in both terms of how they look and the function. It can charge anything. Lately they've been keeping my Steam Deck alive while I'm out and about.
