Goldshell MINI DOGE III PLUS Litecoin & Dogecoin Miner 810Mh/s

·

Mining cryptocurrencies like Litecoin (LTC) and Dogecoin (DOGE) has become more accessible than ever, thanks to compact, efficient hardware such as the Goldshell MINI DOGE III PLUS. Designed for both beginners and experienced miners, this Scrypt-based ASIC miner delivers a robust hashrate of 810 Mh/s while consuming just 500W of power—making it a strong contender in the mid-tier mining market.

Whether you're exploring merged mining or simply want a quiet, reliable rig for home use, the MINI DOGE III PLUS offers an ideal balance of performance, energy efficiency, and ease of setup.

Key Specifications

Released in July 2024, the Goldshell MINI DOGE III PLUS is built with modern mining demands in mind. Its compact design makes it suitable for home environments, while its low noise output ensures it won’t disrupt daily life—ideal for first-time miners or those with space constraints.

Performance & Efficiency

The MINI DOGE III PLUS shines in both raw performance and energy efficiency. At full power, it achieves 810 Mh/s, placing it competitively among other Scrypt miners in its class. However, what sets it apart is its energy-saving mode, which reduces power consumption to just 300W while maintaining a still-impressive hashrate of 620 Mh/s.

This flexibility allows users to adjust settings based on electricity costs and network difficulty, helping maximize profitability over time.

With an efficiency rating of approximately 0.617 joules per megahash (J/MH), this miner ranks among the more efficient options available for Scrypt-based coins. Lower energy usage translates directly into higher net profits—especially crucial in regions where electricity prices are high.

Merged Mining: Mine More Coins, Same Effort

One of the standout features of the Goldshell MINI DOGE III PLUS is its support for merged mining—also known as Auxiliary Proof-of-Work (AuxPoW). This innovative technique allows miners to simultaneously mine multiple cryptocurrencies that share the same hashing algorithm (in this case, Scrypt), without compromising performance.

For example, while mining Dogecoin, the device can also contribute hash power to Litecoin or other Scrypt-compatible chains. This dual (or multi-chain) validation enhances blockchain security and increases potential earnings—all from a single machine.

Originally introduced by Namecoin in 2011, merged mining has gained renewed relevance as smaller networks seek security through larger ones. By leveraging this feature, users can diversify their mining returns without additional hardware investment.

Ideal Use Cases

Home Mining Setup

Thanks to its 35 dB noise level, the MINI DOGE III PLUS operates nearly silently—comparable to a whisper. This makes it perfect for residential setups where noise pollution could be a concern.

Beginner-Friendly Entry Point

With plug-and-play functionality, built-in Wi-Fi, and remote monitoring via a web interface, new miners can get started quickly without technical expertise.

Energy-Conscious Miners

Those looking to minimize environmental impact or reduce utility bills will appreciate the adjustable power modes and high-efficiency design.

Profitability & Return on Investment (ROI)

Estimating ROI depends on several factors: current coin prices, network difficulty, pool fees, and local electricity costs. As of mid-2025, mining Dogecoin and Litecoin with the MINI DOGE III PLUS typically yields a payback period ranging from 8 to 14 months, assuming average electricity rates of $0.10–$0.12 per kWh.

Daily profitability fluctuates but generally falls between $1.50 and $3.00 USD, depending on market conditions. Using online calculators that factor in real-time data can help refine these estimates.

Frequently Asked Questions (FAQs)

What is the expected lifespan of the Goldshell MINI DOGE III PLUS?

With proper ventilation, stable power supply, and regular dust management, this miner can operate efficiently for 3 to 5 years. Environmental factors like heat and humidity play a significant role in longevity.

How does electricity cost affect mining profitability?

Electricity is the largest ongoing expense in mining. At $0.10/kWh, the MINI DOGE III PLUS remains profitable for Scrypt coins. However, rates above $0.15/kWh may significantly reduce margins unless offset by high coin prices or merged mining rewards.

Does the miner come with a power supply?

Yes, the unit includes a compatible power supply unit (PSU), so no additional purchases are required for initial setup.

Can I monitor the miner remotely?

Absolutely. The device supports both Ethernet and Wi-Fi connectivity, allowing you to access its dashboard from any browser-enabled device on the same network—or remotely with proper configuration.

Is merged mining safe and reliable?

Yes. Merged mining does not compromise the security of either blockchain. Since both chains use the Scrypt algorithm, work done on one is valid for the other when properly configured through supported pools.

What coins can I mine with this device?

Primarily designed for Dogecoin (DOGE) and Litecoin (LTC), the miner also supports other Scrypt-based cryptocurrencies such as Bellscoin, Syscoin, and Verge, especially when using merged mining pools.
