Unless you have very cheap / free power they are not worth much.
With free power, at today's prices and difficulty those make up to 120$ a month on Nicehash, however, the altcoin mining profitability is a roller coaster, so that might not hold for too long, the next day it could be 1$, so it's not even easy to know if they are worth fixing, mining any Altcoin except for LTC and Doge is a massive risk, it has always been since ETH moved to PoS, I really hope people stop wasting their money on these altcoin miners.
the Insilicon A11 Pro can mine Dogecoin efficiently. Since Dogecoin uses the Scrypt algorithm, which is exactly what the A11 Pro is designed for, it's well suited for mining DOGE.
The A11 Pro is particularly good for Dogecoin mining because, It's specifically built for Scrypt algorithm cryptocurrencies (Dogecoin, Litecoin, etc.)
Its high hash rate (around 1.35 GH/s) makes it powerful enough to mine Dogecoin profitably if your electricity costs aren't too high
You can also set it up for merged mining, which allows you to mine Dogecoin and Litecoin simultaneously
