The battery life of the NEBULA Mars 3 projector is pretty solid. The manufacturer claims it can last up to 5 hours on a single charge, which is great for outdoor movie nights or long streaming sessions.
But just keep in mind that if you're using it on the brightest settings or running a lot of built-in apps, you might see the battery life dip a bit.
According to our research, you'll generally get around 4 to 5 hours, give or take, depending on how you're using it.
So, whether you're planning for an evening movie marathon outside or taking it on a camping trip, the Mars 3 should have you covered for several hours of entertainment.
