Each miner includes a 365 day warranty from Bitmain, starting from when the miner ships to you from our Virginia warehouse (no tariffs or import fees).
Two C13 power cables (sold separately) carrying 220v power will be required for operation.
Bitmain sells its miners well in advance of being manufactured. A "May batch" preorder would mean the miner will be produced and shipped sometime in the month of May, 2021. Due to shipping delays, preorder miners are often delivered as long as two weeks after manufacture date.
