This powerbankwill recharge  the Nebula Capsule mini projector in our Campervan Package. The powerbank is 100w output and 20,000 mah. This is sufficient to recharge the Nebula capsule mini projector approx 1.75 times, extending the battery life to about 8 hours. Of course, you can then recharge the powerbank wherever convenient and repeat. Great if you are going off grid for a while.
