A report on the Omega Trail Charger Compressor from the folks at Airguns of Arizona…
If you are a PCP shooter and don’t have a SCUBA shop or other HPA air supplier readily at hand, refilling can be a bit of a challenge. Sure, there are quality hand pumps available for very reasonable prices, and they work great to top off the air reservoirs on airguns. Wouldn’t you rather be shooting than spending time pumping or driving back and forth to the SCUBA shop?
There are multiple portable compressors now available on the market for the PCP enthusiast and and prices are coming down commensurate with the smaller sizes. Measuring 13.75 by 12.25 by 6.75 inches and weighing approximately 28 pounds, it is air and water cooled. This design provides a longer working life by efficiently dissipating the heat generated by the work the compressors is doing. A four-stage pump design, it runs on 12 volts DC. A voltage inverter is supplied so the unit can also be used with either 110/220 AC house voltage. A six-foot long cable is built in for connecting the unit to a car battery while in the field. A user-adjustable pin system inside the pressure gauge is used to automatically stop the unit once the desired pressure is reached.
