Battery-powered projectors with Power Bank function

Power Bank function

— the ability to use the built-in battery as an external power bank for third-party devices. The projector not only operates independently, but also charges a smartphone, TV stick, router, or headphones while on the go or traveling. Unlike just a "built-in battery," which powers only the projector itself, the Power Bank expands the possibilities — for instance, you can watch a movie in the yard in the evening while simultaneously charging your phone.
