Good question,
Over the years, we have learned that using a single USB 3.0 type A port will generally be OK. PCs seem to supply adequate power to our device over a single cable. Places where you can see issues is with ultraportable devices like the Surface Pro line. If you only have a single USB type A cable and it does not supply adequate power, then we recommend a USB 3.0 hub that has external power.
If you only have a USB type-C port, you will need to use an external hub that performs power negotiation/use external power. A hub such as the Anker hub linked below has been reported to work with our devices. Using a direct type-C to type-A adapter usually will not work, we believe due to power issues.
