The Speed Chuck from Xlab-USA is a compact and ultra-lightweight CO2 inflator made from anodized aluminum. Unlike standard CO2 inflators, the Speed Chuck allows the user to control the release of CO2 for slower, incremental inflation; it inflates the standard way too with just a quick push, completing inflation in just under 1 second. The Speed Chuck requires threaded cartridges and works with both Presta and Schrader valves.
