Morphology
The phrase pairs 'energy' (power) with 'vampyre/vampire' (a being that drains or exploits others), so a B1 learner who knows both words can infer a metaphorical meaning of something that 'drains' energy. However, the specific technical sense referring to electrical appliances drawing standby power is a narrower, specialized extension that is not fully predictable from the constituents alone.
Etymology
Energy vampire uses the picture of a vampire quietly taking energy even when you are not looking. People call a device an 'energy vampire' when it keeps using power while switched off, so it means 'a device that uses electricity even when turned off'.
