Bitfortun BS-4 - 18 TH/s Bitcoin Miner

Four BM1373 chips bring the BS-4 to roughly 18 TH/s on about 300 W. That is the point where a home machine starts to need a little thought about placement: it still runs on a standard outlet, but it produces real heat and real airflow noise.

The payoff is hashrate density. One BS-4 does the work of three or four single-chip miners on one power cord and one network port, which makes it considerably simpler to live with than a shelf of small units.

Safety and intended use

This is specialised computing hardware for hobbyist and enthusiast use. It generates continuous heat and requires unobstructed ventilation, a suitable electrical supply and a stable surface clear of flammable material. It is not a household appliance and is not intended for use by children. Confirm that your circuit can carry the load continuously before installing, and never obstruct the intake or exhaust.

Mining hardware is sold as equipment only. Network output depends on factors outside our control — network difficulty, pool selection, firmware configuration, ambient temperature and your electricity tariff — and we make no representation about financial returns of any kind. Please read our Risk Disclosure before purchasing.
