All units are certified to FAA TSO-C71 and qualified to multiple RTCA/DO-160G requirements, providing confidence for installation in the cockpit or cabin. The TWC15 Series of wireless chargers have built-in protections for short circuit, over-load, over temperature, power surge, reverse polarity installation, and foreign object detection (FOD), allowing the unit to handle unforeseen conditions safely.
However, compatibility with all current or future devices may not be guaranteed. True Blue Power continues to be proactive in evaluating new devices and strives to continually improve the product as needed to serve the vast majority of Qi and Qi2 compatible personal electronic devices (PEDs).
MODIFICATIONS This product has a nameplate that identifies the manufacturer, part number, description, certification(s) and technical specifications of the unit. It also includes the “MOD” or modification number representing notable changes in the hardware design of the unit. Modification (MOD) 0 is the initial release of the product and is identified on the nameplate by the lack of marking on the MOD numbers 1 through 9 (i.e.
SECTION 3 INSTALLATION GENERAL INFORMATION This section contains interconnect diagrams, mounting dimensions and other information pertaining to the installation of the TWC15 family of Qi/Qi2 Compatible Wireless Chargers. After installation of cabling and before installation of the equipment, ensure that power and ground are applied to the proper pins specified in Section 3.3.2, Pin Assignment Information.

3.4.2 Pin Assignment Information and Location See Table 3.2 for pinout definition and Figure 3.1 for pin locations. Pin Number Signal Aircraft Power (12-32 VDC) Ground Status Enable Table 3.2 Wireless Charger Pin Assignment Figure 3.1 Wireless Charger Pin Locations Note: Pins should be crimped using Molex Hand Crimp Tool 213309-1000 or equivalent.
3.4.4 Harness Verification Note: The TWC15 High Power Wireless Chargers have built-in reverse polarity protection for the power connector. If Pins 1 and 2 are swapped, the unit will not be damaged, but will also not function. Once the cable harness is prepared, prior to connecting the TWC15, activate the aircraft power bus and use a multimeter to verify that aircraft power and ground are supplied with appropriate voltage on the proper pins within the mating harness.

Figure 3.7 Magnetic Alignment Installation (-22 Configuration Shown) Mounting the TWC15 -22 unit to utilize the magnetic alignment requires that the charger be exposed and contact the device being charged directly. This can be accomplished in a number of ways. One option is shown above in Figure 3.6. Note that an appropriate recess is required to allow clearance for the connecting power harness.
SECTION 4 OPERATION UNIT ARCHITECTURE The TWC15 Series Wireless Chargers convert an aircraft (DC) input voltage (from 12 to 32 volts) to a wireless charger that can charge personal electronic devices compatible with the Qi wireless specification. The unit is designed as a DC-to-DC converter output to meet the Qi standard that regulates wireless charging up to 15 watts.
OPERATIONAL MODES AND ALARM CONDITIONS The TWC15 High Power Wireless Chargers provide external status via connector pin #3. Table 4.1 provides indications for all operational modes and alarm conditions. Operational Mode Status Indication Status Indication (-21) Units (-22) Units Blink three times, Power On then go to Standby Standby / Available...
No periodic scheduled maintenance or calibration is necessary for continued airworthiness of the TWC15 series Wireless Chargers. If the unit fails to perform to specifications, the unit must be removed and serviced by Mid-Continent Instruments and Avionics or their authorized designee.
