  • Add USB Power and Charging to Your Aircraft
  • Dual USB configuration gives simultaneous fast 3A charging from each port
  • Charge two full-size iPad® tablets or similar smart devices while using them at full brightness
  • Halo lighting around each USB port makes connections easy in dark conditions
  • Offers easy installation in an existing instrument cutout with optional adapter plate
  • Two charger formats — for straight or 90-degree power wiring connection — help simplify installation in tight spaces such as armrests or sidewalls

Small and Simple to Install

The slimline GSB 15 charging hub measures just over 1.5” square and stands less than an inch deep — making it one of the smallest dual-port USB charging hubs ever designed for aviation use. It comes in two formats: one designed to be wired into aircraft power from the back of the unit — and one that connects to aircraft power through the bottom of the case. Choose the version that fits best with your application and its related space constraints.

Data Passthrough

If your aircraft is equipped with a GI 275 Flight Instrument you will also appreciate GSB 15 for its data transfer capabilities. Using a USB flash drive and the GSB 15, you can transfer databases to a GI 275 flight instrument. Databases will then also be synced among multiple GI 275 flight instruments in a single cockpit. In addition to database updating, GSB 15 can also be used to save flight logs — including engine data2 — from the GI 275 to a USB flash drive.

Fits Tight Spaces and Budgets

You can mount GSB 15 virtually anywhere. It’s small enough to fit a 1” cutout — and it’s available with an optional 1” decorative cover or mounting plates that allow for easy installation in existing, unused 2.25” or 3.125” instrument holes in the panel. And all GSB 15 models use the same power input connector, so the USB Type-C equipped versions can be an easy upgrade from an existing dual Type-A installation3. GSB 15 has FAA TSO and, consequently, European approval. The device will fit in a variety of constricted spaces — such as aircraft sidewalls, armrests or aft console positions — where most aviation USB chargers are simply too large or unwieldy to install.
