Tiny but powerful battery-powered projector
I've had and used many projectors but this one is the most fun.
Crenova HDP300 Smart Mini Projector running Android 7.1, has 170 ANSI Lumen (DLP) with 7000mAh battery, WiFi, with preinstalled Netflix, Youtube but supports casting from Android, iPhone or PC
I forgot to say that is it also very well build and has metal housing so it also feels like robust and premium device.
