Have you been searching for a reliable portable generator that offers both power and quiet operation? The Pulsar Products GX400BN might just be the solution you need. With its 4000W peak power, dual-fuel capability, and ultra-quiet performance, this generator is built for versatility, whether you’re using it for home backup, RV trips, or outdoor events.
Why the Pulsar GX400BN Stands Out
The GX400BN isn’t just another portable generator—it’s packed with features that make it a strong contender in its class. From dual-fuel flexibility to its ultra-quiet operation, this unit is designed to deliver power without the usual noise and hassle.
Dual-Fuel Capability for Versatility
One of the biggest advantages of the GX400BN is its ability to run on both gasoline and propane. This means you’re never limited to one fuel type, giving you flexibility in emergencies or when fuel availability changes.
- Gasoline Performance: 4000 peak watts / 3200 running watts
- Propane Performance: 3600 peak watts / 2800 running watts
Switching between fuels is simple, allowing you to choose the most convenient option based on cost, availability, or storage needs.
Powerful Yet Ultra-Quiet
Noise is a major concern with generators, but the GX400BN operates at just 62dB at half-load—quieter than a typical conversation. That makes it perfect for camping, RV trips, or home use without disturbing the peace.
Key Features of the Pulsar GX400BN
This generator is built with convenience and performance in mind. Here’s what sets it apart:
RV-Ready & Parallel Capability
If you’re an RV enthusiast, you’ll appreciate the TT-30R RV outlet, making it easy to connect to your vehicle. Plus, the parallel capability allows you to link two compatible Pulsar generators, doubling your power when needed.
Portable Yet Sturdy Design
Moving the GX400BN is effortless thanks to its trolley-style frame with wheels and a handle. Weighing approximately 96 lbs, it’s heavy-duty but still manageable for transport.
High-Speed Engine for Reliable Power
The 5.5HP, 149cc OHV engine ensures stable performance, whether you’re using it for emergency power or outdoor activities. It starts up quickly and maintains consistent power output.
Performance Breakdown
To help you visualize its capabilities, here’s a quick comparison between gasoline and propane modes:
| Feature | Gasoline | Propane |
|---|---|---|
| Peak Watts | 4000W | 3600W |
| Running Watts | 3200W | 2800W |
| Runtime (Approx.) | 10-12 hrs (50% load) | 8-10 hrs (50% load) |
| Noise Level | ~62dB (half-load) | ~62dB (half-load) |
While gasoline delivers slightly more power, propane offers cleaner burning and longer storage life. Your choice depends on your priorities.
