For car tires ideal, fast and powerful. Only suitable for my inflatables, since the measuring range is only suitable for high-pressure vessels. Since it must be remeasured with another device. Inflating a larger inflatable boat takes about 30 minutes, which can be annoying. Furthermore, the hose triggers very often from device- here was not working accurately.
Conclusion: Those who have no way to transport aufgepumt a boat, a real volume pump should increase, to refill them enough in any case.
