Harkwood USB-PD Type-C Dual Port Charger V3
Note: For installation instructions, CoA, and Permit information please click here.
Dual port USB-C charger supporting the USB-PD standard. Up to 45 W per port and is suitable for a 14V or 28V power system. The output power level can be adjusted to meet the available aircraft power or regulatory requirements.
Each charger is supplied with:
- A pre-made ETFE aircraft power cable tail (1m long)
- Loose power input connector and crimp pins (enough to make 2 cables) for self-installation.
WHY IT MATTERS IN AIRCRAFT
Generic chargers cause real problems
Generic plug-in USB chargers are not designed for use in aircraft. They typically generate significant electrical interference that degrades radio communications, affecting audio quality and squelch behaviour, and can reduce GPS and radio navigation sensitivity.
Poor voltage regulation in cheap chargers can also damage connected devices, and they often have little, or no, safety features.
Designed around aviation requirements
Our chargers are designed for use in light aircraft. They’re built for continuous operation, and a low RF signature is treated as a design constraint rather than an afterthought.
The same design principles were applied in our Charge2 and Charge4 units, which have been in cockpits since 2014.
TYPICAL USE
Navigation devices
iPads, tablets, and dedicated aviation GPS units are running continuously in flight.
Electronic conspicuity
Portable EC devices such as PilotAware.
Phones and comms
Modern phones and tablets need higher and reliable power to ensure they maintain charge when in use at high brightness levels.
USB POWER DELIVERY
USB-PD R3.2 v1.0
Compatible with modern fast-charging and high-power devices. Each port independently negotiates voltage and current with the connected device. While retaining backwards compatibility with older USB devices.
Independent port operation
Unlike some multi-port chargers, power remains uninterrupted on one port when a device is connected to or disconnected from another. Connecting a new device doesn’t affect what’s already running.
PROTECTION AND SAFETY
- Over-voltage and under-voltage protection – clean shutdown if supply falls outside safe limits
- Per-port overcurrent protection
- Over-temperature protection
- Reverse polarity protection
- Suitable for 14 V and 28 V aircraft power.
MOUNTING OPTIONS
Direct panel mount
Chargers can be directly mounted in an instrument panel. Dimensions are on the specifications page.
Circular instrument cutout adapter
Adapter plate for standard 57mm and 32mm circular instrument panel cutouts. Avoids the need for a cutout in an existing panel.
Version 2 replacement adapter
Specific adapter for replacing an existing version 2 charger unit. Reuses the existing cutout and mounting points.
