In my opinion, the ZenBeam E1 proves to be worthy of what is being advertised as a portable projector. It comes with a built-in 6,000 mAh battery which can last you a long period of continuous use, and with its built-in speaker that’s using their homegrown SonicMaster, you can expect a very enjoyable experience overall.

The small ZenBeam E1 projector is an Android- and iOS-compatible mobile device. Being as small as the palm of your hand, the projector is thin and light with its integrally molded, aluminum-alloy case. The simple, elegant, and round design features an ergonomically easy-to-hold structure. The lens cap has fine concentric patterns, enabling the user to project images simply by sliding the cap. The built-in battery, which can be used continuously for five hours, can also be used as a mobile battery rated at 6,000 mAH, providing a user experience backed up by portability and multiple functionality.

The ASUS ZenBeam E1 is a portable pocket projector which exceeds my expectation and there are many opportunity to bring this device out and use it in and maybe even camping at night in a tent.

The ASUS ZenBeam E1 beats most competition with its brightness and longer battery life.

Great price-specification ratio.
