Bitcube puts Bitcoin mining on a desk: what the new home miner actually offers

Power Mining announces a touchscreen miner using a Canaan chip. Preorders, whole-device electricity use and solo-mining rewards explained.
A small miner, still on preorder
Power Mining announced Bitcube on October 21: a palm-sized Bitcoin miner with a touchscreen, USB-C power and Wi-Fi. The Latvian company says it designed and manufactures the device using chips supplied directly by Canaan. For a newcomer, the appeal is a self-contained machine that can sit on a desk instead of an industrial mining installation.
The product page checked on October 22 accepts preorders and advertises Christmas delivery. That is the company’s target, rather than confirmation that customer shipments have started. Quiet operation and easy setup are also manufacturer claims; this announcement is not an independent noise or performance test.
What 777 GH/s means
The advertised maximum is 777 GH/s in Turbo mode and about 550 GH/s in Quiet mode. Hashrate means the number of attempts the chip makes each second at Bitcoin’s proof-of-work puzzle. One thousand gigahashes equal one terahash, so the larger figure is 0.777 TH/s, not 777 TH/s.
The Avalon A3197 is an ASIC: a chip built for a particular calculation, here Bitcoin’s SHA-256 algorithm. A chip supplier and the maker of a finished device need not be the same company. In this case, Power Mining is the device manufacturer and Canaan supplies the mining chip.
Measure power at the socket
The specification lists 20–25 W from the wall for the complete device. The page separately describes chip power and chip efficiency. Those chip-only values leave out the rest of the machine and power conversion, so they should not be compared directly with another miner’s whole-device electricity bill.
At a constant 25 W, one machine would use 0.6 kWh over 24 hours: 0.025 kW multiplied by 24. Multiply that amount by your actual electricity tariff to estimate the energy cost. This is a simple consumption example, not a forecast of earnings, and the lower-power operating mode needs its own measurement.
A pool payment and a solo win are different
Bitcube supports standard mining pools and solo mining, according to the launch release. In a shared-reward pool, participants combine work and receive rewards under that pool’s rules. Fees, minimum payouts and the time needed to reach them still matter when a device contributes a small amount of computing work.
Solo mining is different: a small machine can work for a long time without finding a block and receive no block reward. A rare success by somebody else does not make your own next attempt more likely. A small desktop miner is easier to accommodate at home; that does not turn it into a regular-income promise.
The screen and the separate virtual offer
The 74 × 74 × 80 mm enclosure includes a 2.73-inch touchscreen, a fan and a heatsink. The screen can show operating information or a clock. The official page also describes a web dashboard and updates over the network. These features explain the convenience, but a browser demonstration is not a verified downloadable firmware package for installation.
A preorder promotion separately offers 777 GH/s of virtual solo mining while the physical unit is awaited. That computing work comes from a hosted service, not a second chip inside Bitcube. Check the offer’s period and service terms separately; neither ordering hardware nor receiving virtual hashrate guarantees a Bitcoin payout.
What remains to be checked
For an eventual purchase, the useful next evidence is delivered hardware, sustained hashrate, socket power, noise in a stated mode and the final shipping terms. Keep preorder timing separate from those measured results. Original diagrams in this report explain the announcement and are not photographs of a tested sample.
The same product page teases a Bitcube Pro at 2.4 TH/s with delivery targeted for the first quarter of 2027. Its fuller specifications are still to follow. It is a separate future product, so its hashrate should not be mixed into the current Bitcube specifications or paired with an invented power figure.
