### **Pros and Cons of Buying a Mitsubishi AL2-24MR-D (AL224MRD) Generator**
The **Mitsubishi AL2-24MR-D** (also known as the **AL224MRD** in some markets) is a mid-range portable generator designed for home backup power, camping, and small-scale commercial use. Below is a detailed breakdown of its advantages and disadvantages.
---
### **Pros**
1. **Reliable Brand Reputation**
Mitsubishi is a well-established manufacturer with a strong track record in power generation. Their generators are known for durability, especially in the mid-to-high price range.
2. **Decent Power Output**
With a **2,400-watt (2.4 kW) rated capacity**, this generator can handle most home essentials during outages, including:- Refrigerators (most models)
- Lights and ceiling fans
- Small HVAC units (with proper sizing)
- Basic appliances (microwave, toaster, etc.)
It also has a **peak output of 2,600 watts**, allowing for short-term handling of higher-starting devices like well pumps or compressors.
3. **Cleaner Fuel Efficiency**
Unlike older generators that run on gasoline alone, the **AL224MRD features a dual-fuel system (gasoline and propane)**. This makes it more fuel-efficient and reduces emissions compared to pure gasoline models.
4. **Quiet Operation**
Mitsubishi generators are generally quieter than many competitors in the same class. The **AL224MRD has a rated noise level of around 68 dB at 23 feet**, which is relatively low for a 2.4 kW unit useful for residential use without disturbing neighbors.
5. **Easy Fuel Switching**
The dual-fuel capability allows users to switch between gasoline and propane without major adjustments, providing flexibility in fuel availability.
6. **Durable Construction**
The generator is built with a **heavy-duty steel frame**, which enhances stability and longevity. The engine is also designed for extended runtime.
7. **User-Friendly Controls**
It features a **digital control panel** with clear indicators for fuel type, runtime, and load status. The **electric start** makes it easier to use compared to pull-start models.
8. **Good for Home Backup**
For most homeowners, a **2.4 kW generator is sufficient** for critical loads (refrigerator, lights, sump pump). It s a better choice than smaller models (like 1,500W) but may require careful load management for larger homes.
9. **Warranty Coverage**
Mitsubishi typically offers a **3-year limited warranty** on parts and labor, which is standard for mid-range generators but better than some budget brands.
10. **Aftermarket Support**
Due to its popularity, spare parts and maintenance services are widely available, reducing downtime in case of repairs.
---
### **Cons**
1. **Higher Upfront Cost**
The **AL224MRD is not the cheapest generator** in its class. Prices typically range between **$800 $1,200**, depending on sales and retailer markup. This makes it more expensive than basic gasoline-only models from brands like Westinghouse or Champion.
2. **Fuel Consumption Can Be High**
While dual-fuel helps efficiency, **gasoline generators still consume fuel relatively quickly** under heavy loads. Propane is more efficient but may not be as readily available in all areas.
3. **Weight and Portability**
At around **120 130 lbs**, this generator is **heavier than smaller models** (like 1,500W 2,000W units). Moving it manually can be difficult, though it comes with **heavy-duty wheels** for easier transport.
4. **Limited Runtime on Gasoline**
On a **full 6.6-gallon gasoline tank**, it provides ** 8 10 hours at 50% load**, which is standard for this class. However, if running at full capacity, runtime drops significantly (around **4 5 hours**). Propane extends runtime but requires refilling more frequently.
5. **Noise at Full Load**
While quieter than many competitors, the **AL224MRD is not silent**. At full throttle, it can reach ** 72 75 dB**, which may still be noticeable indoors or in quiet neighborhoods.
6. **Requires Proper Load Management**
A **2.4 kW generator cannot power an entire home** only essential circuits. Users must **carefully calculate their load** to avoid overloading. Running too many high-wattage appliances simultaneously can cause the generator to shut off or damage itself.
7. **Maintenance Requirements**
Like all generators, it needs **regular oil changes, air filter cleaning, and spark plug checks**. Neglecting maintenance can lead to **engine failure or reduced lifespan**.
8. **Limited Inverter Technology**
Unlike **inverter generators** (e.g., Honda EU series), the **AL224MRD is a conventional generator**. This means:- It produces **less stable power** (not ideal for sensitive electronics like laptops or medical devices).
- It is **noisy and less fuel-efficient** compared to inverter models.
9. **Propane Connection Can Be Inconvenient**
While dual-fuel is a plus, **propane tanks must be manually connected**, and some users find the setup less convenient than a pure gasoline model.
10. **Resale Value Declines Over Time**
Generators, like cars, lose value quickly. If you plan to sell it later, the **AL224MRD may not retain much resale value** compared to newer or inverter models.

### **Conclusion**
The **Mitsubishi AL2-24MR-D (AL224MRD)** is a **solid mid-range generator** that excels in **reliability, fuel flexibility, and quiet operation** making it a strong choice for **home backup power, RVs, or small businesses**. It is **better than budget generators** in terms of build quality and longevity but **not as efficient or quiet as inverter models**.
**Best for:**- Homeowners needing **reliable backup power** for essentials (refrigerator, lights, sump pump).
- Users who want **dual-fuel flexibility** (gasoline/propane).
- Those who prioritize **brand reputation and durability** over fuel efficiency.
**Not ideal for:**- **High-tech users** who need clean, stable power (inverter generators are better).
- **Extreme portability needs** (heavier than smaller models).
- **Budget-conscious buyers** (cheaper gasoline-only models exist but with trade-offs).

### **Recommendation**
If you need a **dependable, mid-sized generator for home backup or light commercial use**, the **Mitsubishi AL224MRD is a strong choice**. However, if **fuel efficiency, quiet operation, and power stability** are top priorities, consider an **inverter generator** (e.g., Honda EU2200i) instead.
**Final Verdict:****Buy if** You want a **durable, dual-fuel generator** for essential home backup and don t mind the higher cost.
**Avoid if** You need **ultra-quiet, fuel-efficient power** for sensitive electronics or portable use.
For most homeowners, **pairing this with a proper transfer switch and load calculator** will ensure it meets your needs without overloading.
