Anyone know how much power you need to run the repeater? Just got mine. I have a few small power bricks, but not a large capacity one. What would be safe?

Any USB power bank should work. Here’s mine

Obviously the higher the capacity, the longer it will last between charges.

My only fear is it going out during the flight while I'm up high lol. Probably should invest in a higher capacity just in case.
I don’t think the repeater draws much power and should last for all your flights. If you are worried just top up the power bank before you fly or you could buy a power bank that has a built-in charge indicator.

Also, if the repeated dies during a flight, it might just switch to the Tello WiFi. When I get some time, I’ll test this in the confines of my house. I’ll just unplug my repeater and see what happens.

Tried unplugging the repeater while Tello was hovering. It just continued to hover in place for about a minute then descended to about 30cm above the floor. It just stayed there and didn’t land. It did not switch to the Tello’s WiFi, nor could I get it to choose it. I had to plug my repeater back in to get Tello to land.

Maybe carrying a phone charging cable to draw power from phone will work as a backup in case your power brick dies mid flight.

Interesting. Thanks for testing that out!

There are some instructions on the forum, for me the app showed an error (I guess because the Tello has no internet connection) but I was able to ignore that and it connected to the Tello and appeared to work fine, haven't had a chance to test out the range of it yet though from what I heard it's about double.
From memory it goes something like this - you need the Mi Home app, set your location to "Other" or the extender won't show up as a supported device. Power the extender and it should be detected by the app when you try to add it, follow the instructions to set it up, it should ask you what wifi network to use at some point, then it goes through a rather long automatic setup, for me during this part the phone would first connect to the extender, then disconnect from it and connect back to the Tello directly, and then eventually the app would show an error, but the LED on the extender showed that everything was OK (green LED if I remember correctly, means it's connected to the hotspot), so I connected to it manually after all that and it worked. Some people have said you can't use a password but that seems to be false. However, if you change the wifi password in the Tello app while it's connected to the extender it seems to screw things up and some people have had to reset their Tello back to factory settings to be able to connect to it again. I might be forgetting something important, but that's the gist of it.
Hi, I’ve tried to get my xiaomi wifi extender ii to work on both my iPad and iPhone, which I’ve used to fly my tello with by the way, but my extender won’t connect to them. I’ve tried using each of the locations and it still won’t work. I’m in Australia and I used both a power bank and a USB charger but I’ve had no luck. Is there some sort of patch or other suggestion as to how I can get it working.
It shows up on the menu to connect to the wifi, but just won’t connect to the mi app.
