    The USB cable for the 3810 is no longer available. The cable for the newer Stick will not work on yours. There is no third party cable, because the WiFi antenna is built into the cable, and without that piece your Stick will not connect to either a network or your remote. Unfortunately, there is no alternative except to replace your Stick with a new model. The 3810 is now five years old, and apparently Roku can no longer source the parts needed for the power cable.

    Now, if you still have the cable and only need the wall power plug, then you shouldn't have any problem using any 3rd party USB power plug that has sufficient power output. So any power cube (that's what I usually call them) with USB output (that's 5 volts) and has at least 1.0 amp output should be fine. If you have one that is at least 1.5 amps, that's probably a better choice, as it won't be pushed to its limit.

Thanks for the reply.  As mentioned I have all the cables, wifi, etc.  Just need the power brick.

If any one one willl work, guess I can stop worrying about getting the exact right one?  That list is very exact.

Thanks,

Sure, the Stick will usually work just from a USB port on the TV itself, although some TVs don't have enough power in a USB port. The USB 2.0 standard only requires 500mA (0.5 amp) and that's not enough for the newer Stick models.

    Thanks again! Found a 5 volt 1.5 amp generic one.

      Yes you're good to go.

      For anyone else reading this.   A USB power adapter you have lying around from some other device, or that you find to purchase, should work as a Roku replacement, as long as the fine print on it says it provides at least 1 amp (1000 milliamps) of current at 5 vdc.  Greater than 1 amp is OK, the Roku will only draw the power that it needs.

    Had my Stick plugged into the USB port on my older Samsung TV and it would take up to a minute to get the Stick to boot to the main ROKU screen. The Samsung TV USB port might have been 1.0 or 1.1., bottom line it wasn't putting out enough juice. Just got a 5 volt 1.0 amp power supply to plug into and now my Stick is super fast loading and bringing up the main ROKU screen.
