Power Consumption Comparison	Medium Power Consumption Suitable for: High-speed transfers for short periods of time, not suitable for long term on.	Most power consuming Suitable for: emergency use, not recommended to turn on for a long time	Most power-efficient Suitable for: Staying connected for long periods of time (e.g. smartwatches, wireless headphones)
