Get one here: https://amzn.to/2PoAyDS
My elliptical is the ProForm 10.0 ZE (which calls for 4 D batteries, or a 6V, 2A adaptor that ProForm charges $25 for)
The product listing (that’s linked) says it’s compatible with the following (NO IDEA if it is or not, just pasting for convenience):
6.0 10.0 ZE, 10.0 14.0 CE, 18.0 RE, 330 395 480 500 F 585 990 CSE 800 600 Zne Ze3 Zx2 Zr3 XP
