Yes, some nail enhancement lights come with built-in batteries. This design makes the nail polish lamp more convenient to carry and move, without worrying about not finding a power outlet or dragging wires during use. Nail enhancement lights with built-in batteries generally require charging and can be used at home or on the go.

However, nail enhancement lights with built-in batteries also have some limitations. For example, the battery capacity is limited, and it may take a long time to fully charge, and the usage time may not be as long as an external power source nail lamp. In addition, the price may also be slightly higher than that of nail enhancement lights with external power sources.

When choosing nail enhancement lights with built-in batteries, the following factors can be considered:

Battery capacity: Choose a nail enhancement lamp with a larger battery capacity for longer use.

Charging time: Understand the charging time to ensure sufficient power before use.

Usage time: Understand usage time in order to arrange time reasonably during usage.

Brand Reputation: Choosing a reputable brand can ensure product quality and after-sales service.

In short, a built-in battery nail polish light is a convenient choice, suitable for use at home or on the go. When choosing, one can weigh personal needs and budget.
