Why have cheap generators with aluminum winding become “disposable”?
Many people remember the times when the brand Kraft & Dele was a sales leader due to its low price. But today these generators are increasingly disappearing from the shelves, and service centers are littered with "dead" iron. The main reason lies inside - this aluminum wiring.
⚡️ The «cheap metal» trap»
To make the design cheaper, manufacturers used aluminum instead of copper. On paper, the power is the same, but physics has its own rules:
- Overheating: Aluminum has a higher resistance. In conditions of long power outages (4–8 hours), the winding heats up much faster, and the insulation simply melts.
- The "hair dryer" effect: An aluminum generator becomes a source of excessive heat, which leads to rapid failure of the automatic voltage regulator (AVR).
📉 Why will they lose in 2026?
- Marathon mode: Modern shutdown schedules demand endurance. Aluminum is a sprinter who dies in the long run.
- Dishonest power: Customers are tired of overpaying for "drawn" numbers (instead of 3.8 kW on the housing, we often get only 2.5 kW).
- Impossibility of repair: Repairing an aluminum winding is often more expensive than the device itself.
💰 Prices for generators in Ukraine (2026 benchmark)
The market has changed. Today, high-quality copper winding has become the standard for reliable brands. Here is a price comparison for high-quality gasoline generators (rated 2.5–3 kW):

| Premium (Honda, Fogo) | Professional copper | 35,000+ UAH |
📊 Copper vs Aluminum: numbers
| Characteristic | Copper winding | Aluminum winding |
|---|---|---|
| Service life | 10–15 years | Seasons 1–3 |
| Max. t° | Up to 200°C | «"Floats" already at 100°C |
| Maintainability | High | Almost zero |
