ASIC devices are designated for cryptocurrency mining. They have a much better hashrate to the energy consumption rate and outperforms GPU devices in this regard.
The Innosilicon A4 Dominator was produced by Innosilicon and released in 2017. This miner consumes 1050W, producing 280.0 Mh/s of hashrate with the scrypt algorithm, which makes this device almost (if not at all) useless. We do not recommend buying this device for mining nowadays.
