In this segment of the video, the speaker discusses the compatibility of a USB-C to DC Barrel connector to power an InvisiGig cell Gateway with a 12V output. They address concerns about the power distribution between USB-A and USB-C chargers, explaining the negotiation process that occurs between the charger and the device being charged. The video also touches on IQ technology and Anchor’s approach to power distribution. The speaker plans to conduct a load test to determine the support of the USB-C charger.

In this segment of the video, the speaker demonstrates using a BK Precision 8601 DC load to analyze an anchor charger that outputs either 5 volts at 3 amps or 9 volts at 2.22 amps, just under 20 watts. The speaker questions whether this charger can step up to 12 volts or if it is only expecting a 12-volt device. They verify the output and test it with different devices, concluding that the charger only outputs 9 volts. Lastly, they check the compatibility with a battery that can output various voltages, highlighting the importance of understanding the device specifications when charging.

In this segment of the video, the speaker discusses the power output and capabilities of a charger claiming to be suitable for 60 and 100-watt laptops. The speaker explains the limitations of a 12-volt rail compared to a 20-volt rail, emphasizing that achieving 60 or 100 watts through a 12-volt rail is not feasible due to power distribution protocols. The speaker then demonstrates testing the charger with a load, observing voltage drops and limitations in current output, concluding that the 12-volt rail is insufficient for reaching high wattage outputs like 60 or 100 watts.
00:09:00
In this segment of the video, the speaker discusses using plug adapters for charging laptops. They highlight that the Apple charger excludes the 12-volt rail, utilizing 5, 9, 15, and 20 volts instead. The adapter negotiates with the power supply and decides to use 9 volts instead of stepping down the 15-volt rail to 12 volts. The speaker mentions that the adapter may work for devices like the IG, drawing around 600-650 milliamps. They suggest using an anchor charger with a 9-volt rail at 2.2 amps for such devices.
00:12:00
In this part of the video, the speaker explains that using a USB that only provides five volts for certain devices like the IG can cause issues due to voltage drops. They mention the internal circuitry of the IG being rated for different voltages and highlight components like the fan and temperature control circuit that require extra power. The speaker warns that running the IG on five volts might lead to intermittent problems or crashes and suggests using higher voltage rails like the 9-volt option. They demonstrate testing different USBC car chargers to find suitable power sources with sufficient amperage for the IG, recommending options that can output 12 volts or more to ensure stable performance.
00:15:00
In this segment of the video, the speaker discusses the power output capabilities of different chargers and their compatibility with specific devices. They mention that a 60-watt or 100-watt charger will suffice, as they support the 12-volt rail needed for charging on the road. The speaker expresses frustration with websites that provide inaccurate information about their products. They also mention testing a 20-watt USB-C charger and believe it should work well with a particular device at 9 volts. The speaker advises against using a 5-volt standard USB-A charger due to potential power drain issues. Additionally, they caution against risking device crashes and recommend avoiding overtaxing the modem.
