Hey guys, since 2 of you already showed some interest - i gonna do a small Tutorial to mod the Kiiro Keon to work with the power supply socket in your home.
before i start, please excuse me when something is written in bad grammar or overall bad english - its not my nativ language. sry xD
first of all, you should have some kind of expierence in soldering. ( dont be afraid its very easy)
you should have some spatchler or old bank card to get the keon open without breaking the plastic clips.
Some screwdriver and a cable cutter would come in handy aswell - but they are not needet.
I gonna link what i bought for the Mod - for better understanding.
Items you gonna need:
- a Power Adapter - we are looking for 15/16V **
- adapter cable between the Power Adapter and the pcb
- Shrink tubing
- soldering iron
- spatchler / old bank or credit card
- a small flat head screwdriver
- hot glue gun
[size=2]* The default Battery is working with 14.8v and runs about 1,6A max - first i thought of getting a battery with more Ah but the chargingport is trash, and since the pcb is between the battery and the charging port there is no way a battery with much more Ah would charge in less than a day.[/size]*
Step.1
find the gap where the outer shell is seated, and go around with the spatchler - a flathead-screwdriver will help to get the spatchler first in. Be careful to not break the pins - go near them and pot some outward presser next to them *pic2
Careful to not loose your buttons
Step.2.0
Find the site where the Battery is Seated. Follow the Battery Cable to the other site, and for savety disconnect the upper connector.
and then cut the cords one after another,Dont CUT both at the Same time - and never let the cutted cords touch each other and secure the Battery with electric tape or shrink tubing.
Step.2.1
Cut the male site of the Extension cord. (pos 2 in the Itemlist)
since you cutted already the Battery - you could remove the the “Batterycable with the Connector” completly for easier soldering. But thats not really needet because we only need to solder 2 wires.

Step.2.2
When you bought Shrink tubing, put some over the cable but push it away from the point where to solder - then remove the insulation from both cables, solder them, put the shrink tubing over it again and heat the shrinktubing with a lighter (or heatgun)
If you disconnected the white connector, put it back in. Connect your cable to your Power Adapter and try to Start the Keon. It should start normally! less than 15v will result in a short flashing red light.
Step.3
I used my Soldering Iron to melt a little bit of the plastic for my Cable to go through, right at the edge where the case is closing
Then i used some Hot glue to hold it in place
Ja, i know you guys already wondering about the foam - since there is now void where the Battery was sitting, i learned that this space will keon use to get louder. a little bit of Foam in this position will work wonders. I think my keon is now even quieter than before (living in a wg 
)
to put it back together lay the shell down, place the buttons in and lay your keon in the right position in it. You need to pull the shell apart the get the 3 pins seated right, make sure to not clip them in right away when they are seated - first make sure your buttons are still in the right position (it maybe takes some try´s to get it right)
There you go, never again need to charge 5-7hours for 1.5hours of cockhero
I really hope that my english wasnt too broken, for everybody to understand.
When u have any questions just reply or pm me. I will do my best to help.
/edit 19.01.2024:

have a look at the guide from quetzaltooth
he did a good job advancing on this and powering his keon through a USB C port on the device.
