Flextail has made it a company mission to fill this gap with tiny battery-powered pumps compact enough for even the most ultralight of trips. All those efforts have led to the new Zero. It's about the size of a fun-size Halloween candy bar and is ready to clip to a keychain or drop in a pocket, bringing automated inflation anywhere you go. A Chinese company with a US office in California, Flextail has been hyper-focused on using modern electrical technology and design innovation to streamline campsites for over a decade. It's chased that goal by releasing everything from portable ice makers, to mosquito repellers, to lanterns but is perhaps best known for its lineup of small, portable battery-powered pumps.
