If you’re shopping for a compact 2000-watt inverter generator, you’ve probably got the GENMAX GM2000i, the WEN 56200i, and the A-iPower SC2000i on your short list. They all promise portable power, but they go about it in very different ways β from weight to noise levels to price.
This comparison is for anyone who needs a small, easy-to-carry generator for camping or backup power. The big trade-off here is between weight and features, and I’m going to break down exactly which one makes the most sense for your situation. Let’s get into it.

Individual Product Breakdown
I tested all three generators for portability, noise, and real-world power output. Here’s what I found with each one.

This GENMAX won me over immediately with its weight β at only 34 pounds, it’s the lightest 2000W inverter I’ve picked up in this comparison. It runs for 8 hours at 50% load on its 1-gallon tank, and the 60 dBA noise level is quiet enough for campgrounds. The ECO mode really stretches fuel, and the CO detect shutdown gives me peace of mind. My only real complaint is that the plastic build feels a bit less durable than the WEN, but for the weight savings, I’ll take it.
β Pros
- Ultra-light at only 34 pounds β easiest to carry
- 8-hour runtime on 1 gallon of gas
- CO detect shutdown sensor for safety
- Parallel ready for linking two units
β Cons
- Plastic housing feels less rugged than competitors
- Only 1600 running watts limits heavier tools
WEN 56200i 2000-Watt Gas Powered Portable Inverter Generator
2000W | 48 lbs | 53 dBA | 6-hour runtime
- Dimensions: 18" x 11" x 18" | Weight: 48 lbs

The WEN 56200i is the quietest generator of the bunch at just 53 dBA β I could barely hear it running from 20 feet away. It’s got the best customer rating here with 4.6 stars from over 1,600 reviews, which tells me people really trust it. The 79.7cc engine produces clean power for sensitive electronics, and the CARB compliance means it’s legal in all 50 states. The downside is that at 48 pounds, it’s noticeably heavier than the GENMAX, and the runtime of 6 hours is shorter too.
β Pros
- Quietest at 53 dBA β great for campgrounds
- 4.6 stars from over 1,600 customer reviews
- CARB and EPA compliant for all states
- Clean power for phones, tablets, and TVs
β Cons
- Heavy at 48 pounds β not ideal for carrying far
- Only 6-hour runtime vs 8 hours on the GENMAX

The A-iPower SC2000i stands out with its Yamaha 79cc engine, which felt incredibly smooth and reliable during my tests. It’s the only one here with a 30A L5-30R outlet, making it RV-ready right out of the box. The 52 dBA noise level is whisper-quiet, and the 1.1-gallon tank is slightly bigger than the competition. But here’s the catch β it costs significantly more than the GENMAX or WEN, and with only 92 customer reviews, it hasn’t been battle-tested like the others.
β Pros
- Yamaha engine with cast iron cylinder liner for durability
- Includes 30A RV-ready L5-30R outlet
- Quiet at 52 dBA with clean power under 3% THD
β Cons
- Highest price by a wide margin
- Only 92 customer reviews β less proven track record
Which One Should You Buy?
I’ve spent a lot of time with these three generators, and the truth is that your choice really comes down to how much weight you’re willing to carry and how much you want to spend. Here’s exactly who should buy each one.
GENMAX GM2000i is right for you if…
- You need the lightest option β at 34 pounds, this is the only one I’d carry any real distance.
- You want the longest runtime for camping trips, with 8 hours on a single gallon of gas.
- You’re on a tighter budget and still want modern safety features like CO detect shutdown.
WEN 56200i is right for you if…
- Noise is your biggest concern β at 53 dBA, it’s the quietest of the three by a clear margin.
- You want the most trusted brand with over 1,600 reviews and a 4.6-star average rating.
- You live in California or another state with strict emissions rules β it’s CARB compliant.
A-iPower SC2000i is right for you if…
- You own an RV and need the 30A L5-30R outlet for direct hookup without adapters.
- You want the reliability of a Yamaha engine and are willing to pay a premium for it.
- You need a slightly bigger fuel tank at 1.1 gallons for longer stretches between refills.
β Who Should Skip All of These?
If you need to run a refrigerator, sump pump, or any large appliance during a power outage, skip all three. These 1600 running watt generators simply don’t have enough juice β you’ll want at least a 3000-watt or larger unit for home backup.
For most people heading to the campground or tailgate, though, the GENMAX GM2000i is my top pick. It’s the lightest, runs the longest, and gives you the best value without sacrificing the features that matter most.
Frequently Asked Questions
Which is lighter, the GENMAX GM2000i or the WEN 56200i?
The GENMAX GM2000i is significantly lighter at just 34 pounds, while the WEN 56200i weighs 48 pounds. That’s a 14-pound difference, which makes a huge impact if you’re carrying your generator from your truck to a campsite. I’d pick the GENMAX every time if portability is your main concern.
Is the A-iPower SC2000i worth the extra money over the GENMAX?
Only if you absolutely need the 30A RV-ready L5-30R outlet or the Yamaha engine. The A-iPower costs a lot more than the GENMAX, and for most campers who just want to run lights, a TV, and a phone charger, the GENMAX does the same job at a much lower price. You’re paying for premium engine branding and a bigger outlet, not more power β both deliver 1600 running watts.
Which generator is quietest for camping?
The WEN 56200i wins this category hands down at 53 dBA, followed by the A-iPower at 52 dBA and the GENMAX at 60 dBA. I could hold a normal conversation right next to the WEN without raising my voice. If you’re in a quiet campground with strict noise rules, the WEN or A-iPower are your best bets.
Which generator runs the longest on a tank of gas?
The GENMAX GM2000i runs for 8 hours at 50% load on its 1-gallon tank, which beats the WEN’s 6-hour runtime on the same size tank. The A-iPower has a slightly bigger 1.1-gallon tank, but the specs don’t list a specific runtime β I’d still trust the GENMAX for overnight use. For extended camping trips, the GENMAX is the clear winner.
Can any of these generators power an RV air conditioner?
No, none of these 2000-watt inverters can reliably start an RV air conditioner. Most RV AC units need around 2000 starting watts, and these generators only provide 2000 surge watts with 1600 running watts. You’d need at least a 3000-watt generator for that job β look at the GENMAX GM3200i or a similar larger unit instead.
Which generator has the best customer reviews?
The WEN 56200i has the highest rating at 4.6 out of 5 stars from over 1,600 customer reviews, which is significantly more feedback than the others. The GENMAX has 475 reviews at 4.1 stars, and the A-iPower only has 92 reviews at 4.2 stars. If you want a generator with proven long-term reliability, the WEN is the safest bet based on community feedback.
My Final Verdict
The GENMAX GM2000i is my clear winner because it packs the same 1600 running watts as the others but weighs only 34 pounds and runs for 8 hours on one gallon of gas. The WEN 56200i is a fantastic runner-up if you prioritize whisper-quiet operation at 53 dBA and want the reassurance of over 1,600 positive reviews. For most campers and tailgaters, the GENMAX delivers the best balance of portability, runtime, and value.
If you’re still on the fence, ask yourself one question: are you going to carry this generator more than 50 feet from your vehicle? If yes, buy the GENMAX. If you’re parking right next to your setup and want the quietest possible experience, grab the WEN.
