GPU devices are very popular in mining cryptocurrencies but the ASIC devices usually outperforms them in many cases. The ASIC device usually consumes less power and has better hashrate.
The Innosilicon A6+ LTCMaster was produced by Innosilicon and released in 2019. This miner consumes 2100W, producing 2.2 Gh/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.
