Product Overview

The Bombax EZ100-C 3800M is a mid-range Ethash algorithm ASIC miner designed for Ethereum Classic (ETC) and other Ethash-compatible cryptocurrencies. Delivering 3,800 MH/s, the EZ100-C 3800M is a more accessible variant in the EZ100-C series — offering a lower entry point into dedicated Ethash ASIC mining compared to the top-tier 3800M model, with correspondingly lower power demands.

The “C” designation in the EZ100-C line indicates a compact or cost-optimised variant compared to the standard EZ100 series. With 3,800 MH/s output, the EZ100-C 3800M is positioned for operators who want meaningful ETC mining throughput in a unit that doesn’t require the same electrical infrastructure as larger 12,500 MH/s machines.

Since Ethereum’s transition to proof-of-stake in September 2022, Ethereum Classic has become the primary large-cap Ethash proof-of-work coin. The EZ100-C 3800M’s dedicated Ethash ASIC architecture makes it substantially more efficient than GPU-based ETC mining, positioning it as a practical choice for South African operators targeting the ETC blockchain.

Key Features

• 3,800 MH/s Ethash Hashrate (±5%): Solid mid-range Ethereum Classic mining output. The EZ100-C 3800M contributes meaningfully to major ETC pools without the infrastructure demands of high-hashrate 10,000+ MH/s machines.
• Dedicated Ethash ASIC Architecture: Purpose-built for the Ethash algorithm, delivering far greater efficiency than GPU-based ETC mining. As dedicated Ethash ASICs proliferate on the ETC network, GPU mining becomes increasingly uncompetitive.
• Moderate Power Consumption: The EZ100-C 3800M’s lower wattage relative to larger Ethash machines makes it more accessible for operators with standard residential or light commercial electrical infrastructure.
• Air-Cooled Design: High-speed fans maintain operating temperatures. Suitable for ventilated mining rooms or rack environments without requiring specialised liquid cooling infrastructure.
• Compact Form Factor: The EZ100-C chassis is designed for shelf or rack deployment in mining spaces where physical footprint matters.
• Standard Ethernet Interface: RJ45 connectivity with web-based management for pool configuration, performance monitoring, and firmware updates.
• Multi-Coin Ethash Compatibility: While primarily targeting ETC, the EZ100-C 3800M is compatible with other Ethash algorithm cryptocurrencies including Ethereum Fair and similar networks.

Power & Installation Notes

The Bombax EZ100-C 3800M’s exact power draw should be confirmed at time of purchase. As a general guideline for Ethash miners in this hashrate class, a dedicated 16A circuit is typically sufficient, with a 20A circuit providing comfortable headroom.

South Africa’s 230V / 50Hz grid supply is compatible with the EZ100-C’s 200–240V input specification — no transformer is required. Wiring must comply with SANS 10142. Engage a registered electrician if you are installing a new dedicated circuit.

Load shedding impact will depend on the confirmed wattage. At lower wattages typical of this hashrate class, a properly sized home inverter (2–3 kVA) with a 5 kWh battery bank may sustain the EZ100-C 3800M through a 2–4 hour load shedding period. Always verify your inverter’s continuous output rating before running mining equipment on backup power.

Ensure adequate ventilation. The EZ100-C 3800M exhausts heat from its fan outlets — deploy in a space with good airflow to keep ambient temperatures below 40°C for reliable, sustained operation.

Electricity Cost Context — South Africa

The exact monthly electricity cost for the EZ100-C 3800M depends on the confirmed wattage. Using Eskom’s approximate residential reference tariff of R2.80/kWh, the formula is:

(Watts ÷ 1,000) × 24 × 30 × 2.80 = Monthly cost (ZAR)

As a reference example, a unit drawing 700W would cost approximately (700 ÷ 1,000) × 24 × 30 × 2.80 = R1,411.20 per month. Confirm the actual wattage at time of purchase for an accurate operating cost estimate. This is a cost estimate only — not a profitability projection. Actual tariffs vary by municipality and supply category.

Ideal Use Cases

• ETC mining entry point: The EZ100-C 3800M offers an accessible entry into dedicated Ethash ASIC mining for operators who want ETC exposure without committing to the cost and infrastructure of high-hashrate 10,000+ MH/s machines.
• Home or small-scale ETC mining: Its moderate power draw and compact form factor make the EZ100-C 3800M suitable for home mining rooms or small commercial setups with standard electrical infrastructure.
• Supplementary ETC mining alongside SHA-256: Operations already running Bitcoin (BTC) SHA-256 miners can add ETC exposure through EZ100-C units without rebuilding their facility infrastructure.
• Fleet building at lower per-unit cost: Running multiple EZ100-C 3800M units in a multi-unit rack configuration can build meaningful aggregate ETC hashrate at a lower per-unit capital cost than single high-hashrate machines.

Frequently Asked Questions

Does the Bombax EZ100-C 3800M work on South African power?
Yes. South Africa’s 230V / 50Hz supply is within the unit’s 200–240V / 50–60Hz input range. No transformer is required. Confirm exact circuit requirements with us at time of purchase.

What coins does the EZ100-C 3800M mine?
The EZ100-C 3800M mines the Ethash algorithm, primarily targeting Ethereum Classic (ETC). It is also compatible with other Ethash coins such as Ethereum Fair. ETC is the primary large-cap Ethash coin since Ethereum’s transition to proof-of-stake.

How does the EZ100-C 3800M compare to the EZ100 12500M?
The EZ100 12500M delivers significantly more hashrate (12,500 MH/s vs 3,800 MH/s) at higher power consumption and cost. The EZ100-C 3800M is the accessible entry point — suitable for smaller operations or operators who want to test the ETC mining landscape before committing to larger hardware.

Which pool should I use for ETC mining?
Major ETC mining pools include 2Miners, Antpool, ViaBTC, and F2Pool. Configure the pool’s Ethash/ETC stratum URL in the miner’s web interface and set up your ETC wallet address as the worker. Most pools support PPLNS and FPPS reward methods.

Can the EZ100-C 3800M handle load shedding?
Potentially yes, depending on confirmed wattage. At its moderate power level, the EZ100-C 3800M may be supportable on a standard home inverter during load shedding outages. Confirm the exact wattage and verify your inverter’s continuous output capacity before relying on backup power for mining.
