Bitmain Antminer L11 (20GH)

All Scrypt algorithm cryptocurrencies, primarily Litecoin (LTC), Dogecoin (DOGE), and Bellscoin (BELLS) through merged mining. Luckycoin, Junkcoin, and Pepecoin also merge mine at varying pool support.

Scrypt merged mining produces multiple coins simultaneously from the same hashrate. The L11 submits Scrypt proof of work once to a merged mining pool, and the pool distributes rewards across LTC, DOGE, and BELLS simultaneously to configured wallets. Combined revenue typically runs 20 to 40 percent above solo LTC at the same hashrate.

L9 at 17 GH/s, 3,570W, and 0.21 J/MH. L11 standard at 20 GH/s, 3,680W, and 0.184 J/MH. The L11 delivers 18 percent more hashrate at approximately 12 percent better efficiency per megahash. Power draw increases approximately 3 percent for the hashrate gain.

3,680W continuous at 0.184 J/MH efficiency. ±5 percent power tolerance produces real world draw between 3,496 and 3,864W. At 220V: approximately 16.7 amps continuous.

Depends on electricity cost and capital constraints. The L11 delivers 20 GH/s at 3,680W and lower per unit cost. The Pro delivers 21 GH/s at 3,612W at a unit premium. At electricity below $0.04 per kWh, the Pro's 7 percent better efficiency does not recover the unit cost premium quickly. Fleet buyers scaling on cheap industrial electricity deploy more L11 standard units for higher total hashrate on the same capital. At electricity above $0.08 per kWh, the Pro's better efficiency typically justifies the premium.

Scrypt merged mining delivers LTC, DOGE, and BELLS simultaneously from the same hashrate, so DOGE is one of three revenue streams rather than the sole income. Combined merged revenue typically runs 20 to 40 percent above solo LTC. Unit level profitability depends on electricity cost, market prices, and network difficulty. Model at your specific power rate using current network data before deployment.

Yes. Box contents: Antminer L11, PSU sized for the 3,680W rated load, power cables, and quick start guide. Contents may vary by batch, exact items in order confirmation.

Yes. MillionMiner hosting services accept L11 units at managed facilities with 220 to 277V infrastructure. Hosting combines facility costs with mining revenue to produce net monthly returns. Contact MillionMiner for hosting rate tiers and availability.

220 to 277V single phase with approximately 20A maximum current. At 3,680W the unit draws approximately 16.7 amps at 220V. Standard commercial 220 to 240V service required, or 220V outlets like those used for electric dryers and EV chargers. Cannot practically run at 110V residential since 3,680W at 120V would require approximately 31 amps. MM's page references 100 to 240V universal, which may reflect PSU input tolerance rather than full rated performance voltage.

Four fan air cooling with front intake and rear exhaust. No external water loops or immersion. Facility requirements: ventilation for approximately 12,557 BTU per hour heat output per unit, adequate intake and exhaust air, ambient temperature within the specified range. Internal temperature sensors manage fan RPM and hashrate throttling under thermal stress.

The L11 and L11 Pro are physically identical: same 400 x 195 x 290 mm chassis, same four fan cooling, same BM1485 chip architecture across 288 chips on four hash boards, same firmware, same voltage specification. No physical hardware difference exists. The only difference is chip binning: L11 Pro uses better performing silicon while standard L11 uses standard grade silicon from the same production process.

DL1 Air at 25 GH/s, 3,725W, and 149 J/GH delivers 25 percent more hashrate per unit and 19 percent better efficiency per gigahash than the L11 standard. The L11 delivers Bitmain's mature firmware ecosystem, broader operator familiarity, and deeper third party firmware compatibility. For operators committed to Bitmain's ecosystem at standard tier pricing, the L11 remains the entry choice. For operators willing to deploy second source hardware with better efficiency, the DL1 Air offers meaningful advantages.

400 x 195 x 290 mm chassis. Weight approximately 15.5 kg per most distributor documentation. MillionMiner's page lists 20 kg which may reflect complete shipping weight with PSU and packaging.

Závisí na napětí, šumu a tepelném výkonu. Napětí: vyžaduje 220 až 277V, nikoliv standardních 110V v domácnostech. Domovy s zásuvkami na 220V spotřebiče (sušičky, nabíječky EV) mohou být vybaveny vhodnými obvody. Šum: 75 dB přesahuje komfortní úroveň v domácnosti a vyžaduje vyhrazený prostor pro těžbu. Tepelný výkon: 3 680 W vyžaduje ventilaci nebo HVAC. Pro tichou domácí těžbu Scrypt jsou vhodnější Fluminer L3 nebo Fluminer L1 Pro.

75 dB industrial noise from four cooling fans. Comparable to a vacuum cleaner or busy restaurant. Disruptive through walls. Requires sound isolated deployment space: dedicated mining room, garage, outbuilding, warehouse. Not suitable for residential proximity without sound containment.

MM specifies 5 to 40 degrees Celsius at 5 to 95 percent humidity. Alternative distributor documentation specifies broader 0 to 75 degrees Celsius tolerance. The conservative range represents optimal operating conditions for sustained hashrate and chip longevity. For hot climate deployments, facility cooling must hold intake air below 35 degrees Celsius under peak load.

Four step setup. Verify 220 to 277V single phase circuit capable of 3,680W continuous (20 amp minimum). Connect PSU to miner and to outlet. Connect Ethernet. Find miner IP, open Bitmain web interface, configure Scrypt merged mining pool URL and LTC/DOGE/BELLS wallet addresses, change default credentials. Verify hashrate reaches 19+ GH/s within 10 minutes.

Major Scrypt merged mining pools accept L11 hashrate including F2Pool, Poolin, ViaBTC, Prohashing, Litecoinpool. Pool fees typically 0.5 to 2 percent. Verify Bellscoin support before deployment since not all Scrypt pools have added BELLS.

Pro factors: standard tier entry into current generation Scrypt hardware, lower per unit cost than the Pro favors fleet scaling on cheap electricity, mature Bitmain firmware ecosystem, merged mining revenue advantage. Con factors: 7 percent less efficient than the Pro from identical hardware, Bitdeer DL1 Air delivers better efficiency at cost of less ecosystem maturity, 75 dB requires dedicated space, 220 to 277V excludes standard residential. For fleet operators with cheap industrial electricity prioritizing total hashrate over per unit efficiency, the L11 delivers better capital economics than the Pro.

For algorithm diversification: Antminer S21 XP (270 TH/s), S23 (318 TH/s), or S23E Hyd 2U (865 TH/s) cover SHA-256 Bitcoin. Antminer KS7 (45 TH/s) covers Kaspa KHeavyHash. Within Bitmain's Scrypt family: L11 Pro (21 GH/s) for higher efficiency at premium unit cost, hydro L11 HU6 (33 GH/s) and L11 Hyd 2U (35 GH/s) for facilities with hydro infrastructure. For quiet Scrypt on separate infrastructure: Fluminer L3 (9.5 GH/s, 45 dB) or Fluminer L1 Pro (6 GH/s, 45 dB). Bitdeer SEALMINER DL1 Air (25 GH/s) provides vendor diversification with better efficiency per gigahash. MillionMiner's ASIC hosting service covers turnkey L11 deployment without facility CapEx.
