Product Overview

The Goldshell MINIDOGE-III is a compact Scrypt algorithm ASIC miner designed for Litecoin (LTC) and Dogecoin (DOGE) merged mining. Delivering 800 MH/s at approximately 300W, the MINIDOGE-III continues Goldshell’s tradition of producing small-form-factor miners for home enthusiasts — combining dual-coin Scrypt mining in a desktop-sized unit that doesn’t require industrial electrical infrastructure.

The MINIDOGE-III is the third generation of Goldshell’s MINIDOGE home miner series. Each successive generation has improved hashrate and efficiency relative to its predecessor, with the III offering better performance-per-watt than earlier MINIDOGE models. Goldshell has built a strong reputation in the compact home mining segment, and the MINIDOGE-III reflects their expertise in producing accessible, quieter alternatives to full-size commercial ASIC hardware.

For South African LTC and DOGE mining enthusiasts, the MINIDOGE-III offers a genuinely home-friendly approach to Scrypt merged mining. Its 300W power draw is manageable on a standard dedicated circuit, its compact form factor fits on a desktop shelf, and its noise output is significantly lower than full-size commercial Scrypt miners — making it one of the most practical dual-coin Scrypt miners for residential environments in South Africa.

Key Features

• 800 MH/s Scrypt Hashrate (±5%): Meaningful LTC and DOGE dual mining contribution from a compact home miner. While lower hashrate than full-size commercial machines, the MINIDOGE-III delivers steady Scrypt earnings at far lower power and noise levels.
• Merged LTC + DOGE Mining: The Scrypt algorithm enables simultaneous merged mining of Litecoin and Dogecoin — both coins earned from every share submitted to a merge-mining compatible pool, with no additional power cost.
• 300W Power Consumption: Low power draw by ASIC standards. At 300W, the MINIDOGE-III runs on a standard dedicated circuit, is manageable on a home inverter during load shedding, and generates modest heat — well-suited to home environments.
• Compact Desktop Form Factor: Designed to sit on a shelf or desk rather than in a mining rack. Physical footprint is comparable to a small external hard drive enclosure, making it practical for home setups where space is limited.
• Low Noise Operation: Significantly quieter than full-size commercial Scrypt ASICs. Not silent, but at a noise level compatible with home offices or dedicated rooms without requiring extensive soundproofing.
• Included PSU: Ships with an integrated or included power supply — plug into a standard wall socket and connect via Ethernet to begin mining.
• Standard Ethernet Interface: Connects to your home network for pool configuration, monitoring, and firmware management.

Power & Installation Notes

The Goldshell MINIDOGE-III draws approximately 300W — low enough to run on a standard South African wall socket with a 16A circuit. A dedicated circuit is recommended for any mining equipment, but the low wattage means this unit does not impose the same electrical planning requirements as full-size commercial Scrypt miners.

South Africa’s 230V / 50Hz supply is within the MINIDOGE-III’s 100–240V input range. The included PSU handles South African mains voltage directly — no transformer required. Simply plug into a wall socket and connect to your home Ethernet network. No registered electrician engagement is typically required for this wattage level, though ensuring the circuit is not overloaded with other loads is good practice.

Load shedding resilience is excellent. At 300W, a standard 1–2 kVA UPS or home inverter can sustain the MINIDOGE-III through most load-shedding periods. A 5 kWh battery inverter can keep the MINIDOGE-III running for approximately 16 hours — covering even the longest Stage 6 outage periods. This makes it one of the best Scrypt miners for South African home miners who want uninterrupted LTC/DOGE mining through outages.

Cooling requirements are minimal. The MINIDOGE-III’s compact design and modest heat output are manageable in a well-ventilated room. Avoid placing it in enclosed, unventilated spaces — standard room airflow with some air circulation nearby is adequate.

Electricity Cost Context — South Africa

At Eskom’s approximate residential reference tariff of R2.80/kWh, the monthly electricity operating cost for the Goldshell MINIDOGE-III is estimated as follows:

(300 ÷ 1,000) × 24 × 30 × 2.80 = R604.80 per month

This is an operating cost estimate only — not a profitability projection. At approximately R605/month in electricity, the MINIDOGE-III has one of the lowest absolute electricity costs of any dual-coin LTC/DOGE miner. This low operating cost, combined with the dual-revenue stream of LTC and DOGE earnings, makes the MINIDOGE-III one of the more accessible Scrypt miners for South African home miners on residential electricity tariffs.

Ideal Use Cases

• Home LTC/DOGE mining enthusiasts: The MINIDOGE-III is purpose-built for home miners who want to participate in Scrypt mining without industrial-grade electrical infrastructure, noise levels, or space requirements. Ideal for South African homes, apartments, or offices with a spare Ethernet port and wall socket.
• Dual-coin revenue with minimal overhead: The merged mining of LTC and DOGE means two coin rewards from one machine. For South African enthusiasts who hold DOGE or LTC long-term, the MINIDOGE-III allows them to accumulate both coins with a single low-wattage device.
• Load-shedding-proof mining: At 300W, the MINIDOGE-III is one of the most resilient Scrypt miners for South African load shedding — sustainable on even modest home battery backup systems for extended periods.
• Portfolio building in Scrypt alongside Bitcoin: Operators who also run Bitcoin (BTC) SHA-256 miners can add LTC and DOGE exposure through the MINIDOGE-III as a low-overhead supplement to their Bitcoin mining activities.

Frequently Asked Questions

Does the Goldshell MINIDOGE-III work on South African power?
Yes. The MINIDOGE-III has a universal 100–240V / 50–60Hz input range, fully compatible with South Africa’s 230V / 50Hz grid. No transformer is needed — plug into any standard wall socket.

Is the MINIDOGE-III quiet enough for a home office?
Yes. The MINIDOGE-III is significantly quieter than full-size commercial Scrypt miners. It is suitable for home offices, spare rooms, and garages. It is not completely silent but operates at a noise level that most people find acceptable in a dedicated home mining space.

What pool should I use for LTC/DOGE merged mining?
Major Scrypt pools supporting LTC+DOGE merged mining include AntPool, ViaBTC, F2Pool, and Litecoinpool.org. Configure the pool’s Scrypt stratum URL in the MINIDOGE-III’s web interface and enable merged DOGE mining in your pool account settings.

Can the MINIDOGE-III run during load shedding?
Yes. At 300W, it can run for approximately 16 hours on a 5 kWh battery inverter system — covering all typical load-shedding stages in South Africa. It is one of the best Scrypt miners for load-shedding resilience.

Is the PSU included with the MINIDOGE-III?
Yes. The Goldshell MINIDOGE-III includes a power supply unit compatible with South African mains voltage (230V / 50Hz). No additional PSU purchase is required.
