Frequently Asked Questions
Should I upgrade from an S9 to an S19j Pro?
If you want to mine profitably, yes. The S19j Pro is much more efficient and still competitive. However, if you are using the S9 purely as a heater, it may still serve that purpose effectively.
How do the S9 and S19j Pro compare as space heaters?
Both convert nearly all electricity to heat. The S9 at 1400W produces about 4,777 BTU/hr while the S19j Pro at 3068W produces about 10,468 BTU/hr. The S19j Pro heats a larger space but also mines more BTC.
