Overview
The Roku 4802CA is a streaming media player supporting 4K UHD output over a wireless connection. At 0.37 pounds, it is small enough to plug in behind a TV and run Roku's channel store for streaming apps.
As a dedicated streaming player, the 4802CA turns any HDMI-equipped TV into a smart TV without needing a built-in smart platform. Its wireless-only connectivity keeps setup to a Wi-Fi connection rather than an Ethernet cable, which suits most home networks but is worth checking against weak Wi-Fi coverage near the TV.
- 4K UHD streaming
- Wireless connectivity
- 0.37 lb compact body

Who it's for
Anyone with a non-smart or older TV who wants 4K streaming apps added on. Not needed for buyers whose TV already runs a capable smart platform such as webOS or Google TV.
Pros and cons

- Small, lightweight form factor

Performance notes
Output is capped at 4K UHD and the device connects wirelessly, so streaming quality depends on home Wi-Fi strength near the TV. Its 0.37 pound weight keeps it small enough to sit unobtrusively behind most TVs.
