Innosilicon A4+ Asic Miner A4 A6 Litecoin 620MH/S Second Hand LTC Miner

The A4+ has a simple design with two fans at the front and rear. This design is in line with the standard design of earlier mining devices. The A4+ LTCMaster is ASIC supported, which means you can control the mining operations while away. The A4+ LTCMaster is quite different from other miners. Due to its unique algorithm, it can mine up to 84 coins. Its most profitable coin is Litecoin. In November 2017, Innosilicon released and started shipping the 14nm A4+ LTCMaster to succeed the A4 Dominator.

The A6 LTCMaster has quadrupled the previous generation's power efficiency, offering more than 8 Mh/s per chip with as low as 1.5W/Mh/s. This feature made the A4 LTCMaster the most profitable mining rig at the time. The A4+ LTCMaster is a customized device for optimized mining with an advanced 14nm process, which has a severe advantage over the previous 28nm nodes.

The device also comes with reliability features like automatic temperature and frequency control, DCDC-less auto onboard chip with a pass/fail/self-test. These features maximize device performance and reduce the risk of overheating. The A4+ continues the fantastic A2 Terminator in serving the mining community.

One feature miners love this device is because of its low power consumption. The LTCMaster has a power consumption of 750W, which is lower than A4+ LTCMaster's 1050W. High electricity costs won't affect miners' profitability. The pools associated with this miner include AntPool, F2Pool.
