ElphaPex DG Home 1 2.1G Dogecoin Miner Overview

The ElphaPex DG Home 1 (also known as Elphapex DG Home 1) is a compact, entry-level ASIC (Application-Specific Integrated Circuit) miner from ElphaPex, a Chinese company specializing in Scrypt-optimized hardware. Launched in early 2024, it’s tailored for home users mining **Dogecoin (DOGE)** and **Litecoin (LTC)** via the Scrypt algorithm, with support for other coins like Bells, LKY, PEP, DOGM, and EAC. Its lightweight design and lower power draw make it beginner-friendly and suitable for small spaces, unlike industrial beasts. Noise is moderate (~65–70 dB), and it’s plug-and-play for desktops.

As of late 2025, with DOGE hovering at $0.18–$0.22, expect ~$2–$3 daily revenue per unit before costs—solid for hobbyists but not farm-scale. Profitability hinges on cheap electricity (<$0.10/kWh) and network difficulty (up ~40% this year). Tools like ASIC Miner Value peg ROI at 12–24 months.

#### Key Specifications
Drawn from manufacturer specs and retailer data

| Specification | Details |
|————————|———————————-|
| **Hashrate** | 2.1 GH/s (gigahashes per second; also listed as 2100 MH/s) |
| **Power Consumption** | 620–630W (standard household outlet compatible) |
| **Efficiency** | 0.3 J/MH (decent for home Scrypt miners; balances power and output) |
| **Algorithm** | Scrypt (DOGE, LTC, Bells, and multi-coin support) |
| **Cooling** | Air-cooled (built-in fans; ~65–70 dB—quieter than pro models) |
| **Dimensions** | ~300 x 200 x 150 mm (compact and desk-friendly) |
| **Weight** | 6–10.3 kg (lightweight for easy portability) |
| **Input Voltage** | 100–240V AC (universal; no special wiring needed) |
| **Operating Temp** | 5–45°C (41–113°F); humidity 5–95% (non-condensing) |
| **Warranty** | 180–365 days (factory defects; some retailers offer extended) |
| **Price (as of Sep 2025)** | $500–$800 USD (budget-friendly; e.g., $600–$700 on major sites) |

#### Features and Performance
– **Home-Optimized**: Slim profile fits on a shelf; user-friendly app for monitoring via Ethernet/Wi-Fi. Auto-tunes for merged mining (DOGE + LTC).
– **Efficiency Focus**: At 0.3 J/MH, it’s ~15–20% better than older Goldshell minis, keeping bills low (~$1.50–$2/day at $0.10/kWh).
– **Build Quality**: Durable plastic/metal chassis with simple LED indicators. Supports overclocking for minor hashrate boosts (+5–10%), but watch temps.
– **Profitability Estimate** (via ASIC Miner Value; assumes $0.10/kWh):
– Daily revenue: ~$2.50–$3.50 (at 2.1 GH/s, current difficulty).
– Daily cost: ~$1.50 (power only).
– Net: $1–$2/day (ROI in 12–24 months; spikes with DOGE rallies).
– Note: Scrypt volatility—DOGE pumps can double output overnight.

Pros and Cons
| Pros | Cons |
|——————————-|———————————–|
| Affordable entry to mining | Modest hashrate (not for pros) |
| Compact & quiet for home use | Moderate noise in small rooms |
| Universal voltage, easy setup| Limited multi-coin flexibility |
| Solid efficiency for beginners| Warranty varies by retailer |

Avoid unverified eBay/Amazon—stick to ASIC specialists for authenticity and support.

#### Tips for Setup
1. **Pool Selection**: Use F2Pool or Litecoinpool.org for DOGE/LTC payouts.
2. **Safety**: Ventilate well; use a surge protector. Run on a stable outlet.
3. **Monitoring**: Apps like Hive OS track performance remotely.
4. **Legality/ROI**: Verify local regs (e.g., noise/energy limits). If DOGE falls below $0.15, consider pausing.
5. **Maintenance**: Dust fans monthly; expect 2–3 year lifespan.
