Works as advertised
I've had one of these Campbell Hausfeld tanks for many years, to carry compressed air outside to work on lawn equipment.

Pros:

- For low air-volume applications, or when you need decent pressure for a short while, it works just fine. It's purpose is to have compressed air on a small job (or tire-filling), where there is no electricity.

Cons:

- After filling the tank (125 psi to 175 psi, depending on your air compressor), pressure will quickly drop below 80 psi once you start using it. So, this tank is only practical for air tool use of very short duration - e.g., an air ratchet wrench to remove a handful of bolts/nuts. Air tools just don't work [well] with insufficient pressure. In fact, with 11 gallons of pressurized air, this tank is only useful for small air-volume applications, regardless of pressure needed. Of course, the tank can be refilled as needed, but that gets tiresome.

With no electricity nearby, options include: this tank, a long extension cord, or a long air hose. Otherwise, any air compressor would be a better choice, since air volume at pressure, will be unlimited. (Of course, the cheapest tank air compressors cost around $100.)
