No, the Nebula P1 speaker has a built-in battery, while the projector does not and requires a power connection to operate.

A built-in battery would increase the device's size and thermal load, potentially affecting performance stability while also limiting weight reduction.

The Anker Solix C300 can charge this product, supporting 3 hours of uninterrupted viewing at full power.
