The Elphapex DG Home 1 is the better choice for home miners who prioritize manageable power demand and lower noise, while the DG2 is designed for professional operators who need substantially more Scrypt hashrate. The DG2 is also more energy-efficient, but its approximately 4 kW power draw, industrial cooling requirements and operating noise make it unsuitable for most living spaces.
Both miners can participate in pools supporting Litecoin and Dogecoin merged mining. However, they belong to different operating classes and should not be compared by hashrate alone.
This review compares their rated specifications and explains how to verify real-world performance. Actual hashrate, wall power, temperature and noise can vary by machine batch, firmware, environment and pool conditions.
Elphapex DG Home 1 and DG2 Overview
The DG Home 1 is a compact Scrypt ASIC designed for smaller installations. The DG2 is a full-size, air-cooled miner intended for farms, dedicated mining rooms and hosting facilities.
| Specification | Elphapex DG Home 1 | Elphapex DG2 |
|---|---|---|
| Algorithm | Scrypt | Scrypt |
| Rated hashrate | 2,100 MH/s | 18,000 MH/s |
| Rated wall power | 630 W | 3,960 W |
| Rated efficiency | Approximately 0.30 J/MH | Approximately 0.22 J/MH |
| Network connection | Ethernet | Ethernet |
| Main environment | Home or small mining room | Mining farm |
| Cooling class | Compact internal cooling system | Industrial air cooling |
| Approximate daily energy use | 15.12 kWh | 95.04 kWh |
Hardware Design and Included Accessories
The DG Home 1 uses a desktop-style enclosure with an integrated power supply and compact cooling system. Its smaller power requirement makes installation easier, although it still produces continuous heat and requires unobstructed airflow.
The DG2 uses a conventional industrial ASIC design with high-speed fans. It requires considerably more airflow and a dedicated exhaust path. Running it in an enclosed room without proper ventilation can increase inlet temperature, fan speed and hardware instability.
Before installation, confirm whether the package includes the correct power cable. Included accessories can vary by supplier and destination.
Rated Hashrate, Power and Efficiency
The DG Home 1 is rated at approximately 2.1 GH/s while drawing about 630 W in standard mode. Its manual also references a higher-performance mode, but increased hashrate comes with higher power consumption and heat.
The standard calculation for energy efficiency is:
Wall power ÷ hashrate
Using rated values, the DG Home 1 delivers approximately 0.30 J/MH. The 18 GH/s DG2 uses approximately 3,960 W, producing an efficiency of about 0.22 J/MH.
The DG2 is therefore more efficient per unit of hashrate, even though it consumes much more electricity in total.
Supported Coins and Scrypt Merged Mining
Both machines support the Scrypt algorithm. They are commonly connected to pools that offer Litecoin and Dogecoin merged mining, allowing compatible work to contribute to both networks.
Merged mining does not mean the ASIC switches repeatedly between LTC and DOGE. The supporting pool manages the process and distributes rewards according to its payout system.
Pool support, fees and auxiliary-coin policies differ. Compare combined rewards rather than estimating profitability from Litecoin output alone. The JSBIT guide Is LTC Mining Profitable? explains how merged mining affects total revenue.
Setup and Initial Mining Configuration
Inspect the miner and electrical environment before switching on the power. Record the serial number because it may be required for warranty verification and technical support.
Power, Network and Cooling Requirements
The DG Home 1’s 630 W rating is manageable for many installations, but the circuit must also support other connected equipment. Avoid overloaded extension cords, damaged adapters and undersized cables.
The DG2 requires dedicated electrical planning. At approximately 3,960 W, it should not be connected to an ordinary circuit without confirming voltage, breaker capacity, plug type, cable rating and continuous-load requirements with a qualified electrician.
Both miners need:
- Stable electricity
- Ethernet connectivity
- Correct pool information
- Clear air intake and exhaust
- Suitable ambient temperature
- Protection from dust and moisture
Do not place either miner against a wall or recirculate hot exhaust into its intake.
Finding the Miner IP and Accessing the Dashboard
Connect the miner to the router using Ethernet and power it on. Allow several minutes for startup.
The IP address can normally be found through the router’s connected-device list or the manufacturer’s IP discovery tool. Open the IP address in a browser on the same local network and sign in using the credentials supplied with the machine.
After the first login:
- Change the default password
- Confirm the model and serial number
- Check the installed firmware version
- Verify that all hashboards are detected
- Review fan and temperature readings
- Set the correct time zone when available
Do not expose the dashboard directly to the public internet. Use a secure VPN or properly configured remote-management system if external access is necessary.
Configuring the Mining Pool, Wallet and Worker
Enter the pool’s Stratum address, worker name and password in the mining configuration page. Configure backup pools so the machine can reconnect if the primary endpoint becomes unavailable.
Before saving, check:
- Correct Scrypt pool address
- Nearest regional server
- Correct port
- Worker-name format
- Payout wallet or pool account
- Backup pool information
After applying the settings, wait for the machine to begin hashing. Confirm performance in both the local dashboard and the pool account.
DG Home 1 vs DG2 Hands-On Mining Performance
A meaningful performance test should run for at least several hours, with 24 hours providing a more representative average. A short dashboard reading can be misleading during startup or pool reconnection.
Miner-Side vs Pool-Side Hashrate
Miner-side hashrate is calculated locally, while pool-side hashrate is estimated from accepted shares. The two values will not match perfectly over short periods.
The DG Home 1 should be evaluated against its approximately 2.1 GH/s rating, while the standard DG2 should be evaluated against its specified 18 GH/s configuration. The purchase contract should state the allowed tolerance.
If pool-side performance remains low, check:
- Pool server latency
- Incorrect configuration
- Rejected or stale shares
- Network interruptions
- Excessive temperature
- Missing hashboards
- Hardware errors
- Unstable power
Use a 24-hour pool average before concluding that the machine is underperforming.
Hashrate Stability During Continuous Testing
Stable hashrate is more valuable than a high number that lasts only a few minutes. Record the 15-minute, one-hour and 24-hour averages where available.
The DG Home 1 is easier to cool because it releases less total heat. However, placing it in an enclosed cabinet can still raise temperatures and reduce stability.
The DG2 moves much more air and releases nearly 4 kW of heat continuously. Its performance depends heavily on separating hot exhaust from cool intake air.
Rejected Shares, Hardware Errors and Uptime
A low reject rate indicates that most submitted work is reaching the pool successfully. Occasional rejected shares are normal, but a persistent increase may indicate network latency, incorrect pool selection or instability.
Also monitor:
- Hashboard status
- ASIC chip count
- Fan speed
- Temperature warnings
- Pool connection history
- Unexpected restarts
- Frequency of zero-hash periods
Record baseline performance before changing firmware or operating modes. Without baseline data, it is difficult to determine whether an update improved or reduced stability.
Power Efficiency, Temperature and Noise Comparison
The largest practical difference is not hashrate but deployment environment.
Rated Power vs Wall-Side Power Consumption
Measure power at the wall using properly rated equipment. Do not use a residential smart plug that cannot safely handle the miner’s continuous current.
Based on rated consumption:
| Electricity Rate | DG Home 1 Daily Power Cost | DG2 Daily Power Cost |
|---|---|---|
| $0.05/kWh | $0.76 | $4.75 |
| $0.08/kWh | $1.21 | $7.60 |
| $0.10/kWh | $1.51 | $9.50 |
| $0.15/kWh | $2.27 | $14.26 |
Energy Efficiency in Joules per Megahash
The DG2’s approximate 0.22 J/MH efficiency is about 27% lower than the DG Home 1’s approximate 0.30 J/MH rating. Lower J/MH is better because the miner uses less energy for the same amount of Scrypt hashrate.
However, buying the more efficient machine is not automatically the better decision. The DG2 requires much greater initial investment, electrical capacity and heat removal.
Operating Temperature, Fan Speed and Noise
The DG Home 1 is better suited to noise-sensitive environments, but it is not silent. Pump, radiator or fan noise remains audible, and room temperature affects cooling behavior.
The DG2 should be treated as industrial equipment. Its high-speed fans can make ordinary conversation difficult nearby. It belongs in a separated mining room, ventilated workshop or professional hosting facility.
If hosting is required, review the Managed Mining Guide before transferring physical control of the machine to a provider.
Elphapex DG Home 1 and DG2 Profitability Comparison
Profitability changes with LTC and DOGE prices, network difficulty, pool payouts and electricity rates. A live calculator should be updated immediately before purchasing.
Estimated LTC and DOGE Mining Revenue
At the same pool and over a sufficiently long period, an 18 GH/s DG2 should generate approximately 8.6 times the gross mining output of a 2.1 GH/s DG Home 1 before considering uptime and pool variation.
This comparison does not guarantee a fixed amount of LTC or DOGE. Network competition and pool results constantly change the actual output.
Electricity Cost at Different Power Rates
The DG2 uses about 95.04 kWh per day, while the DG Home 1 uses approximately 15.12 kWh. The DG2’s electricity cost is therefore about 6.3 times higher, despite delivering roughly 8.6 times the rated hashrate.
This difference explains the DG2’s efficiency advantage. However, facilities may also charge extra for cooling, power distribution and management.
Hardware Price, Net Profit and Payback Period
Calculate daily net profit by subtracting electricity, pool fees, cooling, maintenance and hosting from daily mining revenue.
The DG Home 1 may offer a lower entry cost and simpler home installation. The DG2 can produce more revenue and better efficiency, but its profitability depends on access to industrial power and competitive electricity.
Do not purchase either miner using only a bullish DOGE forecast. The Dogecoin Price Prediction for Miners explains how price, difficulty and operating costs interact.
How to Upgrade Elphapex DG Home 1 and DG2 Firmware
Firmware upgrades may improve stability, pool compatibility or device management, but the wrong image can make a miner unusable. DG Home 1 and DG2 firmware must never be treated as interchangeable.
Checking the Current Firmware Version
Sign in to the dashboard and locate the system, overview or firmware section. Record:
- Miner model
- Serial number
- Current firmware version
- Hardware or control-board revision
- Pool settings
- Network configuration
- Current hashrate and temperature
Take screenshots or export settings when supported. Only update when there is a clear reason, such as an official bug fix, compatibility improvement or manufacturer support instruction.
Downloading and Verifying the Correct Firmware
Use the official Elphapex firmware download center. Select the exact model and read its description before downloading.
Confirm that the file is specifically intended for DG Home 1 or DG2. Do not rely on the similar “DG” model name, and do not install firmware for DG1, DG1+, DG2+ or DG2 Mini.
If Elphapex publishes a checksum, compare it with the downloaded file. When the correct image is unavailable or the model is unclear, contact Elphapex support before proceeding.
Installing Firmware Through the Miner Dashboard
Use a computer connected to the same stable network as the miner. Then:
- Sign in to the miner dashboard.
- Open the firmware or system-upgrade page.
- Select the correct official firmware file.
- Choose whether to preserve settings, if that option is provided.
- Start the upgrade once.
- Keep the miner and router powered during installation.
- Do not refresh the page or close the browser prematurely.
- Wait for the miner to reboot completely.
- Sign in and verify the new firmware version.
Do not upgrade during unstable power, thunderstorms or planned facility maintenance. Never interrupt an update because the progress indicator appears slow.
Post-Upgrade Testing and Troubleshooting
After rebooting, confirm the model, firmware version, hashboards, fans, temperature and pool settings.
Allow the miner to warm up and compare its performance with the recorded baseline. Watch the pool-side hashrate for at least several hours.
If the miner does not return:
- Check the router for a changed IP address
- Confirm Ethernet connectivity
- Allow additional reboot time
- Power-cycle only after the upgrade should have finished
- Follow the official recovery procedure
- Contact Elphapex support before attempting a downgrade
A factory reset may erase pool, password and network settings. A downgrade should only be performed with firmware explicitly approved for that model and hardware revision.
Conclusion: Should You Choose the DG Home 1 or DG2?
Choose the Elphapex DG Home 1 if you want a compact Scrypt miner with manageable electricity demand and lower operating noise. It is the more practical option for home users, beginners and small deployments.
Choose the DG2 if you have dedicated electrical infrastructure, strong ventilation and a location that can tolerate industrial noise. It delivers far more hashrate and better rated efficiency, but it is not a plug-and-play home appliance.
In both cases, confirm the exact batch specifications, measure wall power, monitor pool-side hashrate and install only model-specific firmware from the official source.
Elphapex DG Home 1 and DG2 FAQs
Can the DG Home 1 and DG2 Mine LTC and DOGE Together?
Yes. Both miners can earn LTC and DOGE through a pool that supports Scrypt merged mining. Reward distribution depends on the pool’s payout rules.
Can Both Miners Run on a Home Electrical Circuit?
No, not in every case. The DG Home 1 is easier to support at home, while the approximately 3,960 W DG2 normally requires dedicated high-capacity electrical infrastructure verified by an electrician.
Does a Firmware Upgrade Erase Pool Settings?
It may. Some firmware interfaces offer an option to preserve settings, but users should record pool, network and password information before every upgrade.
Can You Install DG Home 1 Firmware on the DG2?
No. The DG Home 1 and DG2 require their own model-specific firmware. Installing an image for the wrong miner can cause boot failure or control-board problems.
Can You Downgrade to an Earlier Firmware Version?
Only downgrade when Elphapex confirms that the earlier firmware supports the exact model and hardware revision. An incompatible downgrade may leave the miner unusable.
Which Miner Is More Energy-Efficient?
The DG2 is more energy-efficient based on rated specifications. Its approximate 0.22 J/MH rating is better than the DG Home 1’s approximate 0.30 J/MH, although the DG2 consumes much more total power.
