I figure this might be of use to someone.

From left to right: 801, 901, 510.

Forgot to mention:

The 801 and 901 have male connection ends on the batteries and female on the atomizers. The 510 has a female connector on the battery, and male on the atomizer.

All have male push-in cartridges to female atomizers on that end.

(Just some useless info for anyone curious about the differences...)
