That means the project cannot be independently explained or reproduced from the accessible details. What can be said is that a USB-C port alone does not make a phone compatible with a conventional external GPU.
What is known about the reported phone build?
A V-Pulse aggregator listing attributes the headline to How-To Geek, but does not provide the originating article’s details. It identifies neither the phone nor the GPU, connection, operating system, implementation, or task used to demonstrate it. No component list, builder statement, or benchmark for the project is available in that listing: V-Pulse’s listing.

Without those details, there is no supported build recipe to follow and no verified performance result to compare. The headline alone cannot establish whether the phone itself used a conventional external GPU connection, or what “working” meant in the demonstration.

USB-C describes a connector, not a guarantee that a device can communicate with an external graphics processor. Charging or sending video over USB-C is different from providing the PCIe tunneling, host-side GPU enumeration, firmware support, and drivers associated with a conventional eGPU setup. A compatibility explainer from LaptopJudge discusses these requirements as general background, not as evidence about the headline build: Smartphone as eGPU: Feasibility & Limits (USB-C Tether).
#1 Best Overall
- 【Up Link & Down Link】Up link: Oculink 4i(PCIE4.0x4), Down Link: PCIEx16(PCIE4.0x4). Only Support Oculink.
- 【Power Supply】This DEG1 supports ATX and SFX standard power supplies, which provides flexible power supply solutions for mini chassis.
- 【Oculink Interfaces】Please kindly note the OCulink interface does not support hot plugging, and the machine needs to be turned off first.
- 【Follow-start Function】The follow-start function is only compatible with MINISFORUM Mini PCs, it requires the use of original wires.
- Note: The GPU is not included.
For a conventional setup, compatibility depends on the whole chain:
- Host interface: The phone must support the relevant data path; the connector’s shape or charging capability is not enough.
- Operating system and drivers: The host must be able to enumerate and use the GPU with compatible software.
- Hardware and power: The enclosure or module must support the host connection and provide the required power.
- Actual function: Charging a phone, outputting video, and accelerating graphics on the phone are distinct outcomes.
The available account does not establish which of these conditions the reported project met.
Rank #2

- Note: The OCulink interface does not support hot plugging, and the computer needs to be turned off to unplug the cable.
What the Khadas example does—and does not—show
Khadas documents Mind Graphics for Khadas Mind and compatible Windows computers with Thunderbolt 3 or Thunderbolt 4. Its documentation also mentions USB-C charging for mobile phones, which is a separate capability and does not demonstrate GPU acceleration on a phone. See Khadas Mind support and its Mind Graphics connection information.
This is an example of an eGPU product documented for computer hosts, not evidence that Khadas hardware was used in the reported phone project or that the product can accelerate a phone.

What to check before trying a phone-and-eGPU setup
Do not buy an enclosure, adapter, or cable based only on a matching USB-C plug or a claim that a device supports charging or video output. First look for explicit documentation for the exact phone, operating system, connection type, GPU, and intended workload. In the absence of that evidence, compatibility remains unverified.
