Goldshell AL Box 2 (720Gh/s)

720 GH/s Blake3 at 360W and 0.5 J/GH efficiency on Goldshell's silent home tier Alephium mining chassis. ±5 percent hashrate and ±10 percent power tolerance per Goldshell official documentation. Released June to August 2024 as the second generation AL Box that doubled the original AL Box (360 GH/s at 180W) at proportional power consumption. The middle tier of the AL Box family lineup, sitting between the entry tier original AL Box and the AL Box II Plus flagship at 1 TH/s.

Same chassis design, same Goldshell firmware ecosystem, same silent home tier deployment profile, but doubled output. The AL Box 2 delivers 720 GH/s versus the original AL Box's 360 GH/s, drawing 360W versus 180W with identical 0.5 J/GH efficiency. Per gigahash electricity cost is identical between the two units. The AL Box 2 represents Goldshell's second generation push to scale up the home tier Alephium mining category, doubling output without compromising the silent 35 dB operation or the 2.2 kg compact desktop format that defines the AL Box family. For buyers choosing between the two units, the AL Box 2 is strictly better on hashrate per dollar of acquisition assuming pricing is reasonable.

The AL Box II Plus at 1 TH/s and 480W (released October 2025) is the current top tier of Goldshell's home Alephium lineup. Same silent design philosophy and similar deployment profile to the AL Box 2, but 39 percent more hashrate at 33 percent more power consumption and slightly better efficiency (0.48 vs 0.5 J/GH). For buyers wanting maximum hashrate within the silent home tier AL Box family, the AL Box II Plus is the upgrade path. For buyers prioritizing minimum acquisition cost or smaller incremental power consumption, the AL Box 2 remains the practical choice within the family. Both units face the same Alephium network economics challenges at current network difficulty conditions.

Different positioning within the home tier Alephium ASIC market. The IceRiver AL0 at 400 GH/s delivers approximately 55 percent of the AL Box 2's hashrate at proportional power and similar efficiency. The AL0 sits as IceRiver's entry tier home Alephium hardware. Per gigahash acquisition cost typically favors the higher hashrate AL Box 2 if pricing is comparable. Brand and ecosystem preference often determines the choice between Goldshell and IceRiver hardware: buyers running mixed Goldshell fleets across multiple algorithms standardize on the AL Box family, while buyers in the IceRiver ecosystem standardize on the AL series. Both face the same Alephium network economics conditions.

Alephium is a Layer 1 sharded blockchain launched in late 2021 that uses Proof of Less Work (PoLW) consensus, an energy-efficient alternative to traditional Proof of Work. Alephium pairs PoLW with the Blake3 mining algorithm and combines a stateful UTXO model with smart contract programmability via a custom virtual machine. The architecture aims to blend Bitcoin's security model with Ethereum's programmability. Mining Alephium means computing Blake3 cryptographic hashes for the network across Alephium's sharded chain architecture, supporting transaction validation in exchange for ALPH token rewards. Operators mine Alephium for direct ALPH accumulation, exposure to the sharded blockchain and PoLW consensus thesis, and diversification beyond established proof of work chains like Bitcoin.

Honestly, no, at current Alephium network conditions and typical electricity rates. MillionMiner calculator at $0.08 per kWh: $0.11 daily revenue, $0.69 daily electricity cost, approximately -$0.58 daily loss. At $0.05 per kWh industrial rate: approximately -$0.32 daily loss. At $0.04 per kWh: approximately -$0.24 daily loss. At $0.02 per kWh: approximately -$0.06 daily, near break even. Break even electricity rate at current Alephium network conditions is approximately $0.013 per kWh, below any commercially available electricity rate globally. The AL Box 2 is currently unprofitable for direct mining revenue at any realistic electricity rate. This is the honest reality of current Alephium network conditions, not a reflection of AL Box 2 hardware quality. Buyers should approach the AL Box 2 as an ALPH accumulation device positioned for long term Alephium network growth, not as an immediate profit generator.

Three specific buyer profiles can rationally purchase the AL Box 2 today despite challenging current direct profit economics. First: ALPH accumulators positioning for long term Alephium network growth, treating the hardware as an ALPH acquisition vehicle at less than spot market price (the daily ALPH yield represents accumulation that pays off if ALPH appreciates 5 to 10 times from current conditions). Second: home miners learning Blake3 mining, ASIC operation, or general crypto mining infrastructure where the AL Box 2's modest 360W power draw and less than $1 daily electricity cost makes the educational cost manageable. Third: existing Alephium miners adding chassis density to current fleets at minimal incremental infrastructure cost. For any of these profiles, the AL Box 2 represents a defensible purchase. For buyers seeking immediate profitable mining, look elsewhere or wait for improved Alephium network conditions.

100 to 240V universal AC input via the included PSU. At 110V the unit draws approximately 3.3 amps continuous. At 220V approximately 1.6 amps. Compatible with any standard residential or commercial electrical outlet worldwide including US 110V, US 220V, European 230V, and Asian 220V. No dedicated 220V circuits, no industrial three phase service, no special wiring required. The universal voltage flexibility makes the AL Box 2 deployable in any residential setting without electrical infrastructure modifications. The 360W power draw fits comfortably within any standard 15A or 20A residential circuit.

35 dB whisper quiet from dual cooling fans at peak operation per Goldshell official specification. Comparable to a quiet library, soft rainfall, or rustling leaves. Substantially quieter than industrial Bitcoin mining hardware (typically 75 dB) and quieter than typical refrigerators (40 to 45 dB). Suitable for deployment in living rooms, bedrooms, home offices, small commercial offices, or any standard residential setting without sound isolation considerations. The AL Box 2 is among the quietest ASIC mining devices available across any algorithm, representing one of the strongest selling points of the entire AL Box family.

198 x 150 x 96 mm miner dimensions at 2.2 kg net weight per most distributor sources (Goldshell official documentation lists slightly different dimensions of 178 x 150 x 84 mm at 2.0 kg in some product material; the 198 x 150 x 96 mm specification is more commonly cited across distributor sources). Compact desktop format approximately the size of a small router or large hardback book. Fits on any shelf, desk, or small mining rack without dedicated infrastructure. Single hand placement and movement. Genuinely one of the smaller ASIC mining devices available, representing the home tier deployment philosophy that defines the AL Box family.

5 to 35 degrees Celsius operating range at 5 to 65 percent humidity tolerance per Goldshell official documentation and most distributor sources. Tighter temperature range than higher tier industrial mining hardware which typically rates to 45 degrees Celsius. The 360W power draw produces approximately 1,228 BTU per hour of heat output, easily absorbed by a typical residential room without dedicated HVAC support. For deployment in hot climates such as the UAE, Texas summer, Arizona, or tropical regions, ambient cooling infrastructure should hold intake air below 30 degrees Celsius at peak load to maintain consistent hashrate and component longevity. The 5 to 35 degrees Celsius range is sufficient for most residential indoor deployment scenarios with adequate ventilation.

Alephium (ALPH) is the primary target via the Blake3 algorithm. Other Blake3-based cryptocurrencies could theoretically be mined if pool support exists, though Alephium is by far the dominant Blake3 mining target. The AL Box 2 cannot mine Bitcoin (SHA-256), Litecoin (Scrypt), Kaspa (KHeavyHash), Ethereum Classic (Ethash), Aleo (zkSNARK), Monero (RandomX), or any other proof of work algorithm outside Blake3. The algorithm specificity is the trade off for the AL Box 2's efficiency advantage over GPU rigs. Operators considering the AL Box 2 should be committed to Alephium as the long term position before purchasing.

Yes. The AL Box 2 ships with an integrated PSU sized for the 360W rated load, along with power cables and quick start guide. Box contents per MillionMiner: AL Box 2 unit, power supply unit (PSU), power cables, and quick start guide. Contents may vary by batch with exact items listed in order confirmation. The integrated PSU eliminates external power brick sourcing decisions and connector compatibility concerns.

Standard ASIC setup. Step one: connect the included PSU to the miner and plug into any standard 100 to 240V wall outlet. Step two: connect Ethernet cable to the router or network switch (Ethernet-only connectivity, no WiFi support despite some marketing claims to the contrary). Step three: find the miner IP through the router DHCP assignment table or network IP scanner tool. Step four: open the Goldshell web interface in a browser, configure Alephium pool URL and ALPH wallet address, change default credentials immediately for security. Step five: verify hashrate stabilizes at approximately 720 GH/s within 10 to 15 minutes of startup. Goldshell's standard firmware and management interface handle pool configuration and monitoring through any modern web browser on the local network.

Major Alephium mining pools accept AL Box 2 hashrate including Lolminer Pool, Herominers, IceRiverMining, K1Pool, F2Pool, and dedicated Alephium pools. Pool fees typically range from 0.5 to 2 percent of revenue depending on pool business model. Standard Stratum protocol with no hardware restrictions on pool selection. Verify pool specifics before deployment including minimum payout thresholds, hashrate reporting accuracy, and Alephium network support. The AL Box 2's modest hashrate combined with current Alephium network difficulty means single unit deployments may take days to weeks to reach pool minimum payout thresholds at some pools.

180-day Goldshell factory warranty (referenced as 6 months in Goldshell official documentation) starting from shipping confirmation date. Covers manufacturing defects and hardware failures under normal operating conditions. Tampering with warranty seal, use of incompatible PSU, exceeding rated voltage input, or physical damage from shipping voids coverage. Warranty claims processed through MillionMiner support with direct Goldshell channel escalation as needed. Goldshell also provides post-warranty paid repair services.

Minimal residential-format ASIC maintenance. Quarterly dust cleaning of the dual fan intakes prevents thermal throttling and premature fan bearing wear. Annual fan bearing inspection with replacement if bearing noise develops. Monitor hashrate continuously through the Goldshell web interface. The AL Box 2 has approximately two years of field reliability data as of April 2026 with no known systemic reliability issues. The modest 360W thermal load means dust accumulation affects performance more slowly than higher power devices, so quarterly cleaning is sufficient under typical residential dust conditions. The AL Box 2 is among the lowest maintenance ASIC mining devices in regular operation.

Yes, though current Alephium network economics make hosting questionable for the AL Box 2. At MillionMiner's standard hosting rates: hosting fees plus electricity often exceed the AL Box 2's daily revenue under current network conditions. Self deployment at home electricity rates produces equivalent or better economics for buyers willing to manage the unit at home. Given the AL Box 2's residential-friendly form factor (35 dB silent, 360W power, universal voltage, 2.2 kg compact desktop), home deployment is the more practical path for most buyers. Hosting becomes more attractive if Alephium network conditions improve or if the buyer specifically wants to avoid all home deployment management overhead. Contact MillionMiner for current hosting rates and to discuss whether hosting makes economic sense for AL Box 2 deployment.

Buy the Goldshell AL Box 2 only if you fit one of these profiles: long term ALPH accumulator who believes Alephium network value will grow 5 to 10 times from current conditions over the next 2 to 3 years and wants to acquire ALPH at less than spot market price through mining; home miner learning Blake3 mining, ASIC operation, or general crypto mining infrastructure where the modest power cost makes education affordable; existing Alephium miner adding chassis density to current fleets. Avoid the AL Box 2 if you are seeking immediate profitable mining revenue, you have no specific Alephium investment thesis, you cannot afford the daily electricity loss as a long term position cost, or you are uncertain about Alephium's long term network viability since the hardware is locked to the Blake3 algorithm with no coin switching flexibility. Honestly assess your buyer profile before purchasing.
