Question #1:  Images of the back of the Roku Express 4K+ (available to pre-order now for $39.99) show it has an HDMI port, a micro-USB port, and a reset button.  Its description says it comes with an HDMI cable, but no mention of an AC power cord.  What provides electricity to run this new model?

Question #2:  What does the $49.99 Roku Streaming Stick + have that the $39.99 Roku Express 4K+ doesn't have?  Is the higher-priced model better in some way(s)?

Thank you in advance to all Roku Community members who take the time to answer and enlighten me!

The USB port is where the power comes from. The Streaming Stick power cord is micro USB also.

Differences other than form factor? The WiFi range on the Stick+ is better. That's it. Just those two.

The Express 4K+ is essentially replacing the Premiere in the lineup (unless they re-introduce it).
