Direct answer: The ElphaPex DG Home 1 generally offers the better low-budget ROI when electricity costs about $0.05/kWh, mainly because its purchase price and installation requirements are much lower. At approximately $0.10/kWh, however, the Home 1 approaches break-even, while the ElphaPex DG2 remains meaningfully profitable due to its superior 0.22 J/MH efficiency. Therefore, the DG Home 1 is better for affordable home mining, while the DG2 is the stronger choice for high-output operations with suitable electrical infrastructure.
Based on an illustrative gross Scrypt revenue of $0.73 per GH/s per day, the DG Home 1 generates approximately $1.53 per day, compared with $13.14 per day for the DG2. These estimates are a snapshot—not a guaranteed return—because DOGE and LTC prices, network difficulty, pool fees and uptime continually change.
DG Home 1 vs DG2 Hashrate, Power Draw and Upfront Cost
The DG2 produces about 8.57 times the hashrate of the DG Home 1 while consuming approximately 6.29 times as much electricity. This makes the DG2 more efficient per unit of hashrate, but substantially more demanding to purchase, power and ventilate.

The central technical advantage of the DG2 is efficiency: it uses about 27% less electricity per unit of hashrate than the Home 1. The Home 1’s advantage is accessibility. A 630-watt load is much easier to accommodate in a residence than a continuous 3,960-watt industrial load.
Dogecoin’s official mining guide confirms that modern profitable DOGE mining normally uses specialized Scrypt ASICs and that Litecoin and Dogecoin can be earned through merged mining without duplicating the hashing work. It also emphasizes the need for reliable power, cooling and a mining pool (Dogecoin mining guide).
Miner Price, Shipping and Import Costs
At the time of research, JSBIT’sDogecoin and Scrypt miner collection listed the DG Home 1 at approximately $550 and the base DG2 at approximately $6,880. The dedicatedElphaPex DG Home 1 product page may show a different live price because ASIC prices move with inventory, batch and market conditions.
Before calculating ROI, request a landed-cost quotation that includes:
- Miner and built-in power supply
- International freight and insurance
- Import duties, VAT or sales tax
- Customs brokerage
- Payment or currency-conversion fees
- Electrical and ventilation work
JSBIT states that standard international delivery is generally handled through major express carriers, but duties may remain the buyer’s responsibility unless a DDP option is arranged. Buyers comparing higher-output equipment can also review the currentElphaPex DG2-family listing, while confirming whether the available unit is the 18 GH/s DG2 or the newer DG2+.
Electrical Setup, Ventilation and Installation Costs
The DG Home 1 draws about 5.25 amps at 120 volts, although actual current varies with voltage and power-supply efficiency. It can usually be accommodated more easily in a home, provided the circuit has sufficient continuous-load capacity.
The DG2 should not be treated as a normal plug-in appliance. At 240 volts, its nominal 3,960-watt load is approximately 16.5 amps before allowing for variance. It generally requires a suitable dedicated circuit, correctly rated wiring, protection equipment and professional installation.
Ventilation requirements are equally different. The Home 1 releases roughly the heat of a small electric heater. The DG2 releases more than six times as much heat and may require ducting, high-capacity exhaust fans or conditioned intake air. Have a qualified electrician verify local code compliance before installation.
Daily Mining Revenue: How Much More Can the DG2 Earn?
Direct answer: Under identical pool and market conditions, an 18 GH/s DG2 should earn approximately 8.57 times the gross revenue of a 2.1 GH/s DG Home 1.
Revenue Calculation Assumptions for a Fair Comparison
The following comparison uses:
- Gross Scrypt revenue: $0.73 per GH/s per day
- Miner uptime: 100% for the headline calculation
- Pool fees: already represented in the chosen net pool-side revenue benchmark
- Continuous rated hashrate and power
- 30-day month
- No cooling power, taxes or repairs
- Hardware prices of $550 and $6,880
The $0.73 figure is a dated planning assumption, not a forecast. Replace it with your pool’s current 24-hour or seven-day payout per GH/s before purchasing.
Daily and Monthly Gross Mining Revenue
| Miner | Gross revenue/day | Gross revenue/month | Difference |
| DG Home 1 | $1.53 | $45.99 | — |
| DG2 | $13.14 | $394.20 | $348.21 more/month |
The DG2 earns approximately $11.61 more gross revenue per day. That does not automatically mean it has better ROI, because it costs substantially more and requires more electricity and infrastructure.
Revenue per GH/s and the Effect of Pool-Side Uptime
When both machines use the same merged-mining pool, their theoretical revenue per GH/s should be similar. What matters is the accepted, rather than displayed, hashrate.
At 97% pool-side uptime:
| Miner | Effective hashrate | Adjusted daily gross revenue |
| DG Home 1 | 2.037 GH/s | $1.49 |
| DG2 | 17.46 GH/s | $12.75 |
Rejected shares, network interruptions, overheating and pool outages reduce revenue, but electricity may still be consumed. Dogecoin’s explanation ofmining pools notes that pools combine hashrate and distribute more predictable rewards according to their own rules.
Net Profit After Electricity: Which Miner Keeps More Revenue?
Direct answer: The DG2 keeps more revenue in absolute dollars and has the better operating margin, but the DG Home 1 exposes the buyer to much less capital risk.
Daily and Monthly Electricity Consumption
| Miner | Daily consumption | Monthly consumption |
| DG Home 1 | 15.12 kWh | 453.6 kWh |
| DG2 | 95.04 kWh | 2,851.2 kWh |
Monthly energy is calculated as:
Power in kW × 24 hours × 30 days
Net Profit at Different Electricity Rates
| Electricity rate | Home 1 daily net | Home 1 monthly net | DG2 daily net | DG2 monthly net |
| $0.05/kWh | $0.77 | $23.22 | $8.39 | $251.64 |
| $0.10/kWh | $0.02 | $0.54 | $3.64 | $109.08 |
| $0.15/kWh | -$0.74 | -$22.05 | -$1.12 | -$33.48 |
At $0.15/kWh, neither miner covers its direct electricity cost under these revenue assumptions. Running at a loss may still make sense temporarily if the heat replaces other electric heating, but that benefit must be measured rather than assumed.
How Cooling and Ventilation Increase Operating Costs
If fans or air conditioning add 10% to the mining load, total consumption rises to approximately:
- DG Home 1: 16.63 kWh per day
- DG2: 104.54 kWh per day
At $0.10/kWh, that extra cooling load costs roughly $4.54 per month for the Home 1 and $28.51 per month for the DG2. Hot climates, restrictive ducting and recirculated exhaust can increase the penalty further.
For alternative cooling layouts and components, browse JSBIT’smining cooling collection before budgeting the installation.
Net Profit Margin per Miner
At $0.05/kWh, the Home 1 retains approximately 51% of gross revenue, while the DG2 retains roughly 64%. At $0.10/kWh, the Home 1’s margin falls to about 1%, versus approximately 28% for the DG2.
That margin advantage explains why the DG2 remains viable at electricity rates where the Home 1 is barely breaking even.
Payback Period at $0.05, $0.10 and $0.15 per kWh
How the ROI and Payback Period Are Calculated
The basic formulas are:
Daily net profit = daily gross revenue − daily electricity cost
Payback period = total upfront cost ÷ daily net profit
Annual ROI = annual net profit ÷ total upfront cost × 100
A complete calculation should use landed and installed cost, not miner price alone. The figures below use hardware price only, so real payback will normally be longer.
DG Home 1 Payback Period at Each Electricity Rate
| Electricity rate | Daily net profit | Hardware-only payback |
| $0.05/kWh | $0.77 | About 710 days / 23.7 months |
| $0.10/kWh | $0.02 | More than 80 years |
| $0.15/kWh | Negative | No payback at current assumptions |
The Home 1’s attractive $0.05/kWh result disappears quickly as electricity becomes more expensive because its energy efficiency is lower.
DG2 Payback Period at Each Electricity Rate
| Electricity rate | Daily net profit | Hardware-only payback |
| $0.05/kWh | $8.39 | About 820 days / 26.9 months |
| $0.10/kWh | $3.64 | About 1,892 days / 62.2 months |
| $0.15/kWh | Negative | No payback at current assumptions |
At very cheap power, the Home 1 has the slightly shorter hardware-only payback. At $0.10/kWh, the DG2 is the clear winner because its higher efficiency preserves a meaningful profit.
How Coin Price, Network Difficulty and Downtime Change ROI
Revenue rises when mined-coin prices increase, but falls when network difficulty or total competing hashrate rises. Pool fees, rejected shares and downtime further reduce actual payouts.
A useful stress test is to calculate ROI at:
- 20% lower gross mining revenue
- 3% pool-side downtime
- 5%–10% additional cooling power
- One month of annual maintenance downtime
- Higher-than-expected shipping or import costs
Taxes must also be considered. In the United States, the IRS states that the fair market value of successfully mined cryptocurrency is generally included in gross income when received (IRS Notice 2014-21).
Conclusion: Which Miner Offers Better ROI for Your Setup?
Choose the ElphaPex DG Home 1 if you want a low-cost entry into Scrypt mining, have limited residential power capacity or value easier heat and noise management. At approximately $0.05/kWh, it offers the better hardware-only payback in this comparison.
Choose the ElphaPex DG2 if you have a suitable 240-volt installation, industrial ventilation and electricity near or below $0.10/kWh. It produces much more monthly cash flow, is more efficient and remains profitable across a wider range of operating conditions.
In one sentence: DG Home 1 is the better low-capital home ROI choice, while DG2 is the better efficiency and high-output choice.
