Only one listing here states 900 rated watts exactly. The other two are nearest fits at 800 and 950 rated watts, and all three are small two-stroke units that burn mixed fuel and suit lights, fans, phone chargers and a slow cooker, not an air conditioner.

Each generator was compared on stated rated and surge watts, weight, tank size, runtime claim, fuel-oil mix and outlets. Where a listing contradicts itself on watts, the guide says so.

RV Gear Lab field notes

The Campsite Fit Check

Start with the job: PowerSmart 1200W 2-Stroke Portable Generator leads this shortlist for Light camp loads and tailgating. Use that fit as a reference point, then compare the alternatives against your own space and workload.
Specs that separate the picks: The first details to compare are 1200 surge, 900 rated watts, 950 rated, 1200 surge watts, 900 peak, 800 rated watts. Confirm the exact model and included components before ordering.
Trade-off to plan for: Two-stroke needs mixed fuel

Before you buy

What Matters Before You Choose a 900 Watt Portable Generator

Key buying criteria so you get the right fit the first time.

01
What 900 watts runs
900 watts covers LED lights, phone chargers, a fan and a slow cooker or a small TV, but not a microwave or air conditioner. Add up your loads before choosing. Check the running watts, not the surge.
02
Two-stroke fuel
These engines need oil mixed into the gasoline at a set ratio, 40:1 or 50:1. The wrong ratio causes smoke or damage. Read the manual's ratio, since one line lists both.
03
Rated versus surge
Surge watts last for seconds, and rated watts are what the unit holds. A small fridge compressor may exceed the surge briefly. Look for the rated figure.
04
Carbon monoxide
These units have no CO sensor listed. Run them outdoors at least 20 feet from tents, windows and vents, exhaust pointing away. Never run one inside a tent or vehicle.
05
Noise and sensitive electronics
Non-inverter two-strokes are loud and produce less clean power. Avoid plugging laptops and CPAP machines without a surge protector. Check for inverter wording; none of these list it.

The one 900 rated watt unit, and the lightest.

Lightest at 34 pounds
12V DC battery charging
EPA compliant

Watch out for

Two-stroke needs mixed fuel
Only about 5 hours at half load

950 rated, 1200 surge watts
35.3 lbs, 1 gallon tank
Up to 8 hours, 12V 8.3A DC

Check price on Amazon

Best for: Overnight light loads

Our take

The strongest and longest-running of the small two-strokes.

Why it made the shortlist

The YolloBike lists 1200W and 950 rated watts from a 71cc two-stroke engine, weighing 35.3 pounds, with a 1 gallon tank that is said to give up to 8 hours. It has a 120V AC outlet, a 12V DC output rated 8.3A and a 50:1 mix.

It has the highest rated watts and the longest runtime claim of the three. Compared with the PowerSmart, it adds 50 rated watts and a longer claimed runtime for a higher price.

What works

Highest rated watts of the three
Longest runtime claim
12V DC at 8.3A
Light at 35.3 pounds

Watch out for

Listing gives two different watt figures
Priciest of the three

Portable Outdoor Generator

900 peak, 800 rated watts
38.5 lbs, 71cc two-stroke
1.1 gal, DC charging cable

The cheapest of the three, for a few lights and chargers.

The yellow 71cc two-stroke generator lists 900 peak and 800 rated watts, weighs 38.5 pounds and has a 1.1 gallon tank for about 5 hours at 50 percent load.

Its sticker is the smallest in the trio.

It suits campers with the lightest loads, such as a few LED lights and chargers, who want the lowest cost. It is the nearest 800 watt fit.

Circuit protection with remote reset
DC charging cable included
Handle and tools in the box

Watch out for

FAQ

Before You Bring One Home

Is a 900 watt generator enough for camping?

For lights, fans, chargers and a slow cooker, yes. It cannot run an air conditioner. The PowerSmart 900W Rated suits those loads.

What is the biggest mistake with two-stroke generators?

Mixing the wrong fuel ratio. The PowerSmart 900W Rated lists 40:1 and the YolloBike 950W lists 50:1. Follow the manual.

Is the YolloBike worth it over the PowerSmart?

If you need longer runtime and 50 more rated watts, yes. Otherwise the PowerSmart 900W Rated is lighter.

How do I start a small generator?

Mix fuel, fill the tank, set the choke and pull the cord. Let it warm, then plug in loads one at a time.

How should I store it?

Run the fuel out or use stabilizer, and keep it dry and cool. Mixed fuel goes stale, so use fresh mix each trip.
