🛡️POWER SAVING COMPARISON
How Much Energy Can You Save?
Traditional Starlink Power Setup:
Battery → Inverter → Starlink AC Adapter → Router → Dish
Typical losses:
- Inverter loss: 10–15%
- AC adapter loss: 10–15%
- Router consumption: 10–20W
👉 Total system waste: 20–30%+ energy loss
Joyvoit DC Solution:
Battery → Joyvoit PoE Injector → Dish
✔ No inverter
✔ No AC conversion
✔ No router power consumption (optional bypass)
👉 Energy savings: up to 20–30%

💡ETHERNET ADVANTAGE
Why PoE + Ethernet Is Better for Starlink
The Joyvoit PoE system uses standard Ethernet cable:
✅ Lower Power Loss Over Distance
- Better than low-voltage DC transmission
- Reduces voltage drop
✅ Flexible Installation
- Place dish far from power source
- Ideal for roofs, towers, remote poles
✅ Stable Data + Power Integration
- Power + data in one cable
- Cleaner and more reliable system
👉 This is especially critical for:
- Telecom towers
- Rural installations
- Long-distance deployments
