If you warranty is up or you don't mind losing it you can try this mod which works well for me. I have a 0ne Spot power supply with 8 barrel connectors. I think the barrel connectors come in 3,5 or 8. I ordered a micro usb to dc converter from amazon. Cut the last barrel connector line and reverse the polarity black to red, red to black. solder wires and wrap with shrink wrap or electrical tape. Plug into the g10. attached is a picture. remember you will definitely void your warranty but it works.
Attached is a pic of the part.
