LTC Miner Innosilicon A4+ 620M Litecoin Mining Machine 720Watt



Product Description:


The A4 + LTCMaster supports ASics, which means you can control mining operations while you are away. The A4 + LTCMaster is completely different from other miners. Thanks to its unique algorithm, it can mine up to 84 coins. Its most profitable coin is Litecoin. In November 2017, Innosilicon released and began shipping the 14nm A4 + LTCMaster to succeed the A4 Dominator.

The miner also has reliability features such as automatic temperature and frequency control, automatic on-board chip without DCDC, and pass/fail/self-test functions. These capabilities maximize device performance and reduce the risk of overheating. The A4 + continues the excellent A2 terminator to serve the mining community.

The A4 + LTC Master has two 12cm 12C3.4A fans, one at the front and one at the back. This fan arrangement, like that of the previous miner, was very effective in reducing overheating.

If you want to purchase an A6 LTCMaster to mine in your home, the device can be very noisy. During normal mining operations during the day, the measured noise is 82dB at a distance of about 20cm from the equipment.most miners have standard noise levels of 60-80 dB. So this miners better use it in mining field.


A. 180-day warranty on new machines. If within the warranty period, the original factory of the miner will be solely responsible.

B. For used miners, we will send the test video with SN code to the customer before shipment to ensure that each miner is in good condition.
