Used Condition one Innosilicon A11 pro 1.Innosilicon A11 Pro ETH (1500Mh), also known as the A11 Pro ETHMiner 8G 1500 Mh. It comes with a maximum hashrate of 1.5Gh/s, which is the predecessor of the 2Gh/s model. This machine is designed for high-performance and efficient mining 2.The A11 Pro has a low operating cost, high ROl, and persistence. Not just that, its environmental features make it easier for the users to work with. 3.The machine can use in any setting. It comes with a noise level of 75 decibels, which is environmentally friendly. 4.The machine comes with the highest Hash Rates among the systems. If you consider being the game-changer as you get an improved version of all Ethereum miners. 5.The GPU comes with a packing punch efficiency of 1.25j/Mh. The high level of efficiency leads to the maximum power consumption of 2500W that makes a difference Please note: this miner machine should running at 220V-240V voltage environment
