We’ve killed enough healthy batteries to know that external ground power is essential. Whether for use during preflighting, toying with newly installed avionics or updating data and flight plans, aircraft batteries can’t sustain a charge for long. That’s why a portable GPU and a battery charger should be in every maintenance hangar. Enhanced Flight’s next-generation plug-in power supplies do both, while also conditioning a battery for increased life. We put the latest generation model 2870A to the test and it earned its keep in just one work day.
Bring On The Amps
Enhanced Flight is branded by Audio Authority, a company with roots in the mobile electronics industry. They originally designed high-end power supply technology and later brought it to the aircraft GPU market. The improved 2870A portable GPU flows an impressive 70 amps of continuous current—that’s enough to easily power the on-board systems in piston singles up to light jets. It also boasts 89 percent efficiency, with an extremely stable and noise-free DC power stream intended to replicate in-flight electrical environments.
