### Elphapex DG2 18G Dogecoin Miner Overview

The Elphapex DG2 (often stylized as DG 2 or DG2) is a high-performance ASIC (Application-Specific Integrated Circuit) miner manufactured by Elphapex (also spelled ElphaPex), a Chinese mining hardware company specializing in Scrypt-based equipment. It’s designed primarily for mining **Dogecoin (DOGE)** and **Litecoin (LTC)**, which use the Scrypt algorithm. Released in early 2025, it’s marketed as a breakthrough in efficiency, being one of the first miners to dip below 0.2 J/MH (joules per megahash) energy use. This makes it ideal for large-scale operations where electricity costs are a major factor, though it’s not suited for home use due to its high power draw and noise levels.

If you’re considering purchasing or using one, note that crypto mining profitability depends on factors like current DOGE/LTC prices, network difficulty, and your electricity rate (aim for under $0.10/kWh for viability). As of late 2025, with DOGE around $0.15–$0.20, a single DG2 could generate roughly $10–$15/day in revenue before costs, but this fluctuates wildly.

#### Key Specifications
Based on official listings from retailers like Apexto Mining, Yesmining, CryptoMinerBros, and Zeus Mining:

| Specification | Details |
|————————|———————————-|
| **Hashrate** | 18 GH/s (gigahashes per second) |
| **Power Consumption** | 3520W–3960W (varies by model variant; e.g., 3520W in some Yesmining units) |
| **Efficiency** | 0.19–0.22 J/MH (industry-leading for Scrypt; lower is better) |
| **Algorithm** | Scrypt (optimized for DOGE, LTC, and other Scrypt coins like Bells) |
| **Cooling** | Air-cooled (multiple high-speed fans; noise ~75–80 dB) |
| **Dimensions** | ~432 x 196 x 287 mm (compact for industrial setups) |
| **Weight** | ~18–20 kg |
| **Input Voltage** | 200–240V AC (standard wall power, but requires dedicated circuit) |
| **Operating Temp** | 5–45°C (50–113°F); humidity 5–95% (non-condensing) |
| **Warranty** | 180–365 days (manufacturer defects; check retailer) |
| **Price (as of Sep 2025)** | $2,500–$3,500 USD (new; varies by seller and stock) |

#### Features and Performance
– **Efficiency Breakthrough**: At 0.19 J/MH, it’s ~20–30% more efficient than predecessors like the Goldshell LT6 or older Bitmain L7. This translates to lower heat output and bills—crucial as Scrypt mining difficulty has risen ~50% in 2025 due to DOGE’s meme-fueled surges.
– **Dual-Mining Support**: Seamlessly switches between DOGE and LTC via mining pools (e.g., F2Pool, ViaBTC). Some variants support “Bells” (another Scrypt coin) for diversification.
– **Build Quality**: Industrial-grade aluminum chassis with robust fans for 24/7 operation. It’s plug-and-play with standard Ethernet for pool connectivity, but you’ll need a PSU upgrade if not included.
– **Profitability Estimate** (rough, using current data):
– Daily revenue: ~$12–$18 (at 18 GH/s, assuming $0.18/kWh electricity).
– Daily cost: ~$8–$10 (power only).
– Net: $4–$8/day per unit (ROI in 8–12 months at scale).
– Use tools like WhatToMine.com for real-time calcs.

| Pros | Cons |
|——————————-|———————————–|
| Top-tier efficiency reduces costs | High upfront price and power draw (not home-friendly) |
| Reliable for DOGE/LTC farms | Loud operation (like a vacuum cleaner on steroids) |
| Compact for its power | Scrypt network volatility (DOGE pumps/dumps affect ROI) |
| Strong warranty from reputable sellers | Potential supply chain issues (Chinese export delays) |

#### Related Models
If 18 GH/s is overkill, check:
– **Elphapex DG1+**: 14.4 GH/s @ 3950W (older, cheaper at ~$2,000).
– **Elphapex DG2+**: 20.5 GH/s @ 3900W (upgraded version, $3,500+).
– **Home Variant (DG Home1)**: 2.1 GH/s @ 630W (quiet, beginner-friendly at $500–$700).

#### Tips for Setup
1. **Pool Choice**: Join a Scrypt pool like Litecoinpool.org for steady payouts.
2. **Safety**: Use in a ventilated space; monitor temps with software like Hive OS.
3. **Legality**: Ensure mining is legal in your area (e.g., no bans in China; energy regs in EU).
4. **Alternatives**: If DOGE dips, consider cloud mining or switching to GPU rigs for flexibility.
