Style: 3,300 Starting Watts


Pattern Name: 49 State


Features

  • PORTABLE POWER FOR HOME BACKUP, CAMPING, AND RV USE: Produces 2,500 running watts and 3,300 starting watts to run a refrigerator, lights, a TV, and phone charging simultaneously from a compact 59.5-pound inverter generator
  • CLEAN POWER SAFE FOR SENSITIVE ELECTRONICS: TruePower Technology produces a stable sine wave with less than 3% total harmonic distortion, making it safe to run laptops, tablets, CPAP machines, and other sensitive devices without risk of damage
  • POWERRUSH ADVANCED TECHNOLOGY DELIVERS 50% MORE STARTING CAPACITY: Reaches 3,300 starting watts to handle the surge demand of refrigerators, RV air conditioners, and motor-driven tools that would overload a standard inverter generator
  • ECONOMY MODE AND COSENSE TECHNOLOGY: Economy Mode adjusts engine speed automatically to cut fuel use and noise; COsense monitors CO levels and shuts the unit down if dangerous concentrations are detected near the unit
  • RUNTIME UP TO 7 HOURS ON A SINGLE TANK: The 1.06-gallon fuel tank delivers up to 7 hours at 25% load or 4.5 hours at 50% load, giving you extended power for overnight camping or a multi-hour home outage without refueling
  • PARALLEL READY WITH MULTIPLE OUTLET TYPES: Features two 120V 20A household outlets, one 120V 30A twist-lock outlet, and two USB-A ports; add a second GP3300i via a sold-separately parallel kit to double your output
  • LIGHTWEIGHT AND FIELD-READY DESIGN: At 59.5 pounds with a molded carry handle, one person can transport the GP3300i; includes a USDA-qualified spark arrestor for use in national forests, parks, and dry-condition outdoor areas
  • WHAT'S INCLUDED AND WARRANTY COVERAGE: Ships with engine oil, oil funnel, and tool kit; backed by a 3-year residential limited warranty and supported by Generac's authorized service dealer network across the U.S.

Description

The Generac GP3300i (model 7153) delivers 2,500 running watts and 3,300 starting watts from a compact, 59.5-pound inverter generator built for home backup power, camping, RV trips, and tailgating. How many watts do you need? A standard refrigerator draws roughly 700W running and up to 2,200W to start. The GP3300i handles that load while leaving headroom for lights, a TV, and phone charging simultaneously. For larger demands, two GP3300i units can be paired via the sold-separately parallel kit (model 7668-0) to deliver up to 5,000 running watts. Clean power for sensitive electronics: TruePower Technology produces a sine wave with less than 3% THD, making it safe to plug in laptops, tablets, CPAP machines, and other sensitive devices directly from the household outlets. RV connection: The generator includes a 120V 30A L5-30R twist-lock outlet. Connecting to a standard RV TT-30R inlet requires an L5-30P-to-TT-30R adapter, not included. The parallel kit includes a dedicated TT-30R outlet when two units are linked. Starting method: This model uses a recoil pull-start system controlled by the PowerDial, which integrates choke, run, and off into one dial. No electric start or remote start option is available on the GP3300i. Fuel: Runs on unleaded gasoline only. No dual-fuel or propane capability is available on this model. Economy Mode reduces engine speed to match your actual load, extending runtime and lowering sound output when full power is not needed. COsense monitors carbon monoxide continuously and shuts the unit down automatically before unsafe concentrations build. Maintenance requires periodic oil changes using 0.6 qt of 10W-30 or SAE 30 oil and spark plug inspection per the owner's manual schedule. Engine oil and oil funnel are included in the box. Backed by a 3-year residential limited warranty. No wheel kit is included.

    • Quiet, easy and efficient
Style: 3,300 Starting Watts Pattern Name: 49 State
This generator is very easy to crank and it is super quiet. I hooked up a small window unit to it and it didn't make a sound change at all from the pull. I love it!

    • Delivers just as advertised and very quiet, but don't expect more than 2000 watts at 5000 feet
Style: 3,300 Starting Watts Pattern Name: 49 State
This Generac 3200i (2500-continuous watts) should do the trick the next time power goes out at our home. I wanted to buy a Honda EU2200i because of its quietness and reputation, but at 5500 feet altitude I didn't think its 1800 continuous watts was up to running the gas furnace, the fridge, and a few lights and battery chargers. The Generac was $500 cheaper and nearly 40 percent more powerful. Out of the box, I had to run at half choke for nearly a minute before it started to run normally. Otherwise, subsequent starting is a breeze. It's wonderfully quiet as well; it definitely won't bother us or the neighbors. And I'm glad I got the bigger wattage. I tested it with several combinations of current draw. It will run two circular saws simultaneously, but the engine bogs way down and my in-line watt meter indicated supply reductions of several hundred watts. That's not a problem for making a single cut but it would definitely be bad for the motors long-term. It powers either circular saw or a 1500-watt milk house heater just fine, but add any two in combination and it bogs down and doesn't recover. The best it could do was to run a milkhouse heater on the low setting (1320 watts draw) and a 6-amp drill (630-watt draw) for a total draw of 1950 watts. That's about right, given a 4 percent reduction in engine output per 1000 feet above sea level. The Generac 3500XL I bought 35 years ago ran great until the plastic gas lines rotted out. I could have repaired the gas lines but I worried about how clean the power would be for electronics these days. This new 3300i isn't pure-sine-wave output, but at 3 percent THD, it's close enough. Thus far, it delivers exactly as advertised. My only wish is that it came with the switch to turn the eco mode off. That might help with starting in colder weather. Maybe that won't be a problem, but I won't know until our first winter comes along. ... show more

Style: 3,300 Starting Watts Pattern Name: 49 State
Bought this for my son and daughter-in-law who are always losing power. They had to toss all the contents of their refrigerator multiple times. This isn't a giant generator but it will keep them from having to do that again. easy to use, quite and seems like really nice quality.

    • Don’t waste your money
Style: 3,300 Starting Watts Pattern Name: 49 State
These generators work fine right out of the box. If you plan on running this generator for maybe an hour or two a month you should be ok. If you plan to use it power anything for a long time. STAY AWAY. It will fail on you. It is not designed to run for a 1000 plus hours. I am on my second one. The first failed at around 1100 hours and the second didn’t last 500 hours. They are literally made to be thrown away. You can’t find parts for them and if you can find parts you can’t get them. Fewer people are servicing these generators. Just stay away. Don’t waste your money. Buy a Honda. ... show more
