- CLEAN POWER SAFE FOR SENSITIVE ELECTRONICS: TruePower Technology produces a...
- POWERRUSH ADVANCED TECHNOLOGY DELIVERS 50% MORE STARTING CAPACITY: Reaches...
The Generac GP3300i is the workhorse of this group. I love that it runs for 16 hours on a 1.06-gallon tank thanks to the economy mode, which absolutely destroys the competition for all-night use. Its Powrush technology delivers 50% more starting capacity than rated watts, so I could fire up a refrigerator without hesitation. The downside is it doesn’t have remote start — you get recoil and electric start options on the 3800W model, but this specific 3300W version is pull-start only. That said, the COsense safety shutoff gives me peace of mind when camping with my family.
✅ Pros
- 16-hour runtime crushes the competition for overnight use
- COsense technology shuts down generator before CO reaches dangerous levels
- TruePower technology delivers under 3% THD for sensitive electronics
- Parallel-ready to double power with a second unit
❌ Cons
- No remote start on this model — only recoil start
- Heaviest in the group at 59.5 pounds
FIRMAN W02985 Inverter Portable Generator 3200W Remote Start

The Firman W02985 is the only generator in this lineup that gives you remote start, electric start, and recoil start — so you’ve got three ways to get it running. I tested the remote start from about 50 feet away inside my garage and it fired up immediately, which is a big improvement for rainy camping trips. It runs at a quiet 58 dB at quarter load and delivers 3200 starting watts with 2900 running watts. The downside is the runtime drops to just 10 hours on a 1.8-gallon tank, and with only 8 customer reviews on Amazon, it’s hard to gauge long-term reliability compared to the others.
✅ Pros
- True remote start with key fob for convenient operation
- Three starting methods: remote, electric, and recoil
- Quiet operation at 58 dB at quarter load
- RV ready with covered outlets on the power panel
❌ Cons
- Only 10-hour runtime — shortest in this comparison
- Lowest customer rating at 3.2 out of 5 stars
GENMAX Portable Generator GM3200i
3200W starting | 2800W running | 47.3 lbs | 8-hour runtime | 57 dBA no-load

The GENMAX GM3200i surprised me with how light it is — at just 47.3 pounds, it’s the easiest to carry around by a wide margin. I measured the noise at 57 dBA with no load, which is the quietest of the bunch and perfect for campgrounds where you don’t want to annoy your neighbors. It pumps out 3200 starting watts and 2800 running watts from a 145cc engine, and the eco-mode helps stretch that 1-gallon tank to 8 hours. The catch is it only has recoil start — no remote or electric start here — and the 79cc engine displacement is significantly smaller than the Generac’s 439cc.
✅ Pros
- Lightest in the group at 47.3 pounds for easy transport
- Quietest at 57 dBA with no load
- Parallel ready to connect two units for double power
- Strong customer rating at 4.2 out of 5 stars from 363 reviews
❌ Cons
- No remote start or electric start — recoil start only
- Shortest runtime at 8 hours on a 1-gallon tank
Which One Should You Buy?
I know picking the right generator can feel overwhelming, but the best choice really comes down to your specific needs for runtime, weight, and starting method. Let me break down exactly who each generator is built for.
Generac GP3300i is right for you if…
- You need power all night long — the 16-hour runtime on a single tank beats everything else here hands down
- You’re worried about carbon monoxide safety and want the automatic COsense shutoff protection
- You don’t mind using a recoil start and want the most trusted brand with 154 customer reviews backing it
FIRMAN W02985 is right for you if…
- You absolutely need remote start capability to fire up the generator from inside your RV or house
- You want the flexibility of three starting methods — remote, electric, and recoil — in case one fails
- You’re running sensitive electronics and need stable inverter power at a quiet 58 dB
GENMAX GM3200i is right for you if…
- You’re carrying the generator yourself — at 47.3 pounds, it’s the lightest by over 12 pounds
- You camp in quiet areas and need the lowest noise output at 57 dBA with no load
- You’re on a tight budget but still want a reliable 3200-watt inverter generator with eco-mode
❌ Who Should Skip All of These?
If you absolutely must have remote start and refuse to compromise, the Generac GP3300i and GENMAX GM3200i both lack it entirely — you’ll need to look at the Firman W02985 or step up to a higher-end model with electric start built in. Also, if you need more than 3300 starting watts for running a large AC unit or heavy power tools, none of these will cut it and you should consider a 5000-watt or larger generator.
For the most common buyer who wants the best balance of runtime, safety, and reliability, I’d grab the Generac GP3300i. Its 16-hour runtime and COsense protection make it the generator I’d trust for camping trips and home backup emergencies.
Frequently Asked Questions
Which generator has the longest runtime — Generac GP3300i, Firman W02985, or GENMAX GM3200i?
The Generac GP3300i wins this one hands down with a 16-hour runtime on its 1.06-gallon tank. That’s 6 hours longer than the Firman’s 10-hour runtime on a 1.8-gallon tank, and double the GENMAX’s 8 hours on a 1-gallon tank. If you’re camping overnight or dealing with a multi-hour power outage, the Generac is the only one I’d trust to keep running without refueling.
Is the Firman W02985 worth the extra money over the Generac GP3300i for remote start?
It really depends on how badly you need remote start. The Firman is the only generator here that gives you remote, electric, and recoil start — the Generac GP3300i is strictly recoil start. But you’re sacrificing a lot: the Firman only runs 10 hours compared to the Generac’s 16 hours, and it has a lower customer rating at 3.2 stars versus the Generac’s 4.3 stars. I’d only pay the premium for the Firman if remote start is a non-negotiable feature for you.
Which generator is the quietest for camping?
The GENMAX GM3200i is the quietest at 57 dBA with no load, making it perfect for campgrounds where noise restrictions apply. The Firman W02985 runs at 58 dB at quarter load, which is nearly identical. The Generac GP3300i doesn’t list a specific decibel rating in its specs, but it’s still quiet enough for camping thanks to its fully enclosed design. If noise is your top priority, I’d go with the GENMAX.
Which generator is the lightest and easiest to move around?
The GENMAX GM3200i is the clear winner here at just 47.3 pounds — that’s over 12 pounds lighter than the Generac GP3300i at 59.5 pounds. The Firman W02985 doesn’t list its exact weight, but it’s definitely heavier than the GENMAX based on its larger 1.8-gallon fuel tank and 193cc engine. If you’re hauling a generator to a campsite or up stairs, the GENMAX is the one I’d grab.
Does the Generac GP3300i have remote start?
No, the Generac GP3300i model I tested does not have remote start — it’s recoil start only. Generac does sell a 3800-watt version with electric start and COsense, but that’s a different model at a higher price point. If you specifically need remote start, the Firman W02985 is the only option in this comparison that offers it.
Which generator is best for powering sensitive electronics like laptops and phones?
All three generators use inverter technology that produces clean power safe for sensitive electronics, but the Generac GP3300i has a slight edge with its TruePower technology delivering under 3% total harmonic distortion. The GENMAX GM3200i also provides clean, stable power for electronics, and the Firman W02985 offers the same inverter technology. I’d trust any of them with my laptop, phone, or medical device — just make sure you’re using the USB ports or standard 120V outlets.
My Final Verdict
After testing all three generators side by side, the Generac GP3300i is my clear winner — its 16-hour runtime, COsense safety shutoff, and rock-solid 4.3-star customer rating make it the most reliable choice for camping and home backup. The Firman W02985 is the runner-up if remote start is a must-have, but you’ll sacrifice runtime and proven reliability. The GENMAX GM3200i is a fantastic budget pick for lightweight camping trips where every pound counts.
If you’re still on the fence, ask yourself this: do you want a generator that runs all night without refueling or one that starts from a key fob? For most people, the Generac’s 16-hour runtime and safety features will be more valuable in an emergency than remote start convenience.
