Questions about this item

How long will the built-in 500mAh lithium battery last before it needs replacing?

The adapter uses a 3.7V 500mAh rechargeable lithium battery charged via DC 5V at 500mA; battery lifespan depends on charge cycles and usage patterns.

What limits continuous operation when the adapter runs all day?

Battery capacity of 500mAh sets the wireless run time; for uninterrupted all-day use the unit must stay connected to a 5V USB power source.

How much heat or fan noise does the adapter produce during extended use?

The adapter has no fan and draws only 500mA at 5V, so it generates minimal heat and operates silently.
