Bitmain Antminer L11 20G – High-Performance Litecoin & Dogecoin Miner

The Bitmain Antminer L11 20G is a next-generation Scrypt ASIC miner built for serious Litecoin (LTC) and Dogecoin (DOGE) mining. Delivering up to 20 GH/s hashrate at around 3680W power consumption, it’s designed for miners who want strong Scrypt performance, excellent efficiency and rock-solid stability.

Engineered by Bitmain as part of the L11 series, this miner is a major step up from previous Scrypt models. It combines high hash power with an optimized air-cooling system and robust build quality, making it suitable for both small mining farms and advanced home or garage setups with good ventilation.

What the Bitmain Antminer L11 20G mines

• Algorithm: Scrypt

• Primary coins:

  • Litecoin (LTC)

  • Dogecoin (DOGE)

• Other Scrypt coins (pool dependent):

  • Bells (BEL) and other Scrypt-based altcoins

Using compatible pools, you can typically mine Litecoin and Dogecoin together via merged mining, so the same hashrate earns rewards on both chains.

Key features

• 20 GH/s Scrypt hashrate
  Provides up to 20 GH/s of Scrypt hashing power, giving you serious performance for LTC and DOGE in a single unit.

• High power, strong efficiency
  Draws around 3680W at the wall, with energy efficiency of roughly 0.184 J/MH. This combination of hashrate and efficiency makes it highly competitive in the current Scrypt miner market.

• Air-cooled with high-speed fans
  The L11 uses a high-performance air-cooling design with dual high-speed fans to keep the miner stable under continuous 24/7 load.

• Industrial-grade noise level
  Rated at around 75 dB, the Antminer L11 is best suited to garages, mining rooms, warehouses or dedicated mining spaces rather than living rooms or bedrooms.

• Built for 24/7 uptime
  Designed specifically for long-term, continuous mining operations with stable performance and reliable hardware.

• Simple network setup
  Uses a standard Ethernet interface. Just connect it to your router or switch, log into the web interface, configure your pool settings, and start mining.
