does exactly as intended. Its pricy for overseas shipping, but 100% still worth it.
Suave and Sleek and for some can last a Week! Yummyyy. Consider the nano too since its suppper tiny and if you might use this more plugged in than not it can be worth it and you can still connect a battery pack or probably even piggyback off your phone through usb.. hold on.. yep thought so!
I just took the part which holds the battery off and removed the battery from this one and plugged it into my phone c to c and it just works.
Including my setup which works using the hub beta firmware, keyboard, mouse and the hub plugged into each other aptly. It is drawing 0.26A for me like this and im pretty sure my hub is a part of the power draw there and out the norm of a good one because of the way its setup it has extra leds which blink constantly but i cant tell really. Im still happy with it since i just calculated using in line power reader that with this setup I would still run almost 20hrs of constant use hooked upto my phone without any other battery or charging and would get alot more if you take breaks from using it like watching or reading something or you play a game and with a controller (thats not going through the sterling ofc) then i would imagine you could get a lot more life out of it (remember the phone is just a battery in this scenario). Also if you just use the one device instead of two through a hub like that you will get more ofc. So consider and consider well for you cant really go wrong but might end up like me and grabbing both even though you didnt see the point of the other initially besides a custom setup for modders done more controlled and miniature, and thats still a cool idea to me I might explore but i just want it for those other reasons too right now that I’ve used it a bunch. But that might not be a bad thing.
Headline: Works well!
I purchased this for my ZSA Moonlander and so far I’m happy with it. It was able to connect to my Arch Linux setup fairly easily and even works with the layer switching and mouse functionality that the Moonlander offers.
Great product worked perfectly!
Alex helped me make it work on archlinux because I was missing some dependencies I had no idea about, he’s the goat highkey
Great shipping times, especially for US customer, product arrived and works without issue.
The product works as advertised, no issues when I used it with CharaChorder + MacOS / Linux.
Possibly the best and most useful tech gadget I’ve purchased in a long time. Update the firmware to 3.0.0 (via a Chromium browser) and it’s flawless. My stupidly expensive custom mechanical keyboards can now function wirelessly from the couch without any soldering or modding required. HIGHLY RECOMMEND. You won’t be disappointed.
This works well—simply plug in the AC power and turn off auto-sleep.
Good Device and fast and friendly customer support!
Works flawlessly and switches instantly between devices
Amazing product and works flawlessly.
Headline: Works great + awesome developer!
Before I even made the purchase, I reached out to Alex and asked if one of my specific keyboards would work. He was very helpful and even offered to write updated firmware if it wouldn’t work. It did end up working out of box, and I’m very pleased with it. Thank you so much for the amazing product, my setup feels so much cleaner now!
