I have done many maths and researches today.
I was this close to buying a Cuboid but my pesky brain stepped in.. "Do the maths"... "You know they are using a Texas Instruments chipset".
I thinks "Dang..." Brain is right.
So I do's the maths...
14W from a 7.4V nom Vin...
I needs a 3.9 ohm coil to keep it at high effiency...
Ummm, No
I thinks " I bet this thing is designed to work best with 0.5-1 ohm
coils."
More maths ensue.
Yup.. 50W at 1 ohm and 100W at 0.5 keeps the chipset in its happy place.
No Cuboid for me.
