From Kegland:

Through feedback and the ingenuity of our RAPT Users Group of FaceBook. KegLand is proud to introduce the wireless charging kit for the KegLand RAPT Pill Hydrometers.

No need to take your RAPT Pill housing apart for charging! Or even to connect to the RAPT Captive Portal.

If the green light does not flash green (captive portal open), it means your battery is insufficiently charged. Leave your pill on the charging pad for 24 hours or until it is fully charged (red light turns off). Then lift the Pill on and off the charging pad and it will activate the captive portal (green light will start to flash)

Please note, if your unit is extremely low battery and you put it on the wireless charging dock. It will not immediately go into the captive portal (green light flashing) Until it is atleast 

Includes:
1 x USB-C Wireless Charging Coil
2 x Adhesive Weight Pads
1 x USB-A to USB-C cord (Power plug not supplied)
1 x Black RAPT Wireless Charging Dock (USB-C)
