Great news to announce: Innosilicon world class R & D team just updated our A4 model, launching the exciting new generation of globally leading miner in power and energy efficiency, the A4+ miner. As a prototype without much optimization, A4+ can already reach 550Mhs, at 750W. The prototype video is available at https://youtu.be/W9z-haTm7nY. A4+ and its subsequent series will be sure to lead the future market, as the powerful weapon of LTC miners.
We will upgrade your preordered A4 LTC miners to A4 + LTC miners or future upgraded products. The remaining payment will depend on the final spec of the miner.For example, you preordered A4 280Mhs miner totally 1500 dollars, if we upgraded to A4+ with 550Mhs, your total payment will be (1500/280)*550 dollars. You will be notified for the remaining payment before delivery.
Subsequent manufacturing updates will be released in time. Future pre-order please still follow the A4 pre-order schemehttp://www.innosilicon.com/html/a4-miner/index.html#Buy.The estimated delivery time starts from Nov 30th to Dec 10th based on payment sequence.
