Power supply 5V 3A 15W USB-C

POW provides yet another great functionality of measuring power consumption. Remote switch POW R2 works pretty much the same way as Basic just with added functionality of controlling and documenting power consumption. As with all the Sonoff products it works with eWeLink making it pretty much compatible with any larger smart home ecosystem.

HDMI - Micro HDMI cable can be used to connect HDTVs to tablets, smartphones or any device equipped with a Micro HDMI socket to experience audio and video quality (up to 1080p) from home. Thanks to the built-in Ethernet network, this cable allows you to share the Internet connection between several devices without having to use a separate Ethernet cable for each of them. Check your device's user manual to make sure you have the right connectors. This cable, made of good materials for HDMI, guarantees clean transmission between HDMI devices. No interference or data loss in digital transmission. Compatible with all HD formats available on the market and suitable for 480p/480i/720p/1080i and 1080p resolutions. Also compatible with HDMI 1.3b.
