Not without an adapter. Echo is KR808D-1 threading. You are 510 threading. Check Altsmoke, Goodprophets,
madvapes for 510 to 808 adapter.
Also - I believe Echo is a 3.7v battery (like slim KR808D-1 are) and Ego/Inferno is around 3.4v so an Echo cartomizer probably won't vape as hot on Inferno as on Echo
You might want to check out Boge LR 2.0 (and the medium 2.5 in your can find them) cartomizers, the most popular cartomizers for Ego-type 510-threaded
batteries. I use the standard resistance Boges because I use the same cartos on my slim manual 510's (and slim
batteries need standard resistance)
