It’d need additional radiation shielding to operate for long periods outside Earth’s magnetosphere. The Lunar Gateway modules are a reasonable blueprint for this.

Also, even with the ISS’s power budget, the VASIMR module wouldn’t operate continuously. The plan was to charge it and then run it for short 15 minute periods. It could operate for longer if it took more power from the ISS. It seems they are considering other options for a flight demonstration.
