TLDR Review: Generac GP3300i Generator
Pros
- •Quiet operation that won’t disturb neighbors, making it great for camping or residential use
- •Reliable, clean, and stable power output with nearly pure sine wave (~3% harmonic distortion), safe for sensitive electronics
- •PowerRush™ technology offers over 50% more starting capacity for tough motoriven equipment like RV essentials or power tools
- •Includes useful outlets: duplex AC outlets, a 30A twistlock outlet, and USB ports for convenient charging of mobile devices
- •Easy to start after initial setup, though it requires a specific pulling technique (feel resistance before full pull) for reliable launches
- •Compact and lightweight design makes it highly portable for outdoor activities or emergency use
- •Comes with convenient starter maintenance items like oil, funnel, screwdriver, and wrenches
- •Runs well at higher altitudes (5000+ feet) providing reliable continuous wattage (~2500W), suitable for home essentials like furnace, fridge, and lights
- •Sized appropriately for use with manual transfer switches in homes
- •Consistent and reliable run time without frequent interruptions
Cons
- •Starts can be tricky at first; requires learning to pull to the compression stroke before a full pull, making it less intuitive than some prior models
- •No user switch to disable eco mode, which might impact starting performance in cold environments or for some heavy loads
- •Struggles to power two heavy loads simultaneously, leading to bogging and reduced wattage
- •Some users reported fuel leakage issues right out of the box, requiring vigilance in storage and handling
- •Generac customer service and local service centers may be unresponsive or slow, causing frustration for repairs or support
- •Starting on LP gas can be inconsistent initially, needing multiple attempts
- •Despite quiet operation, it’s not whispeuiet, so those expecting ultra-silent performance might want to look elsewhere
Bottom Line
The Generac 7153 GP3300i is a solid, portable inverter generator delivering reliable, clean power with helpful features like USB ports and COsense safety technology. Its PowerRush™ boost is perfect for motor-driven equipment, and its quiet, lightweight design suits outdoor and emergency use. However, startup requires some getting used to, and occasional fuel leaks and slow customer support may pose drawbacks. If you want a no-fuss, highly portable inverter with reliable output and safety features, this is a great choice. For easier starting or ultra-quiet operation, you might want to compare with other inverter generators, but overall Generac’s blend of power and portability makes it a winner here.
