  • The 9 Best 5,000-Watt Portable Generators

    1. Champion Portable Generator – Best Overall

    Champion 100496

    Champion is a well-known brand and they come in as our top pick. When buying a generator, you are certainly thinking about power, but other than that, safety is something high on the list. If you start running low on oil, the generator will automatically shut off. It’s also a really powerful generator. With 6,250 starting watts and 5,000 running watts, this generator will last up to nine hours of runtime on a full tank of gasoline.

    This generator isn’t the quietest on the block, but from 25 feet away, this puts out a decent 70 db. Also, you won’t have to worry about this generator frying precious electrical equipment, as the volt guard prevents overloads and keeps your valuable equipment safe from voltage spikes. On-board computer systems keep track of voltage, frequency, and operating hours. This generator comes standard with a three-year warranty.

    There’s really nothing about this product to complain about, which is why it’s our top pick!

    • Designed for safety
    • 6,250 starting and 5,000 running watts
    • Nine hours of runtime
    • Pretty noisy

    2. JEGS Portable Generator – Best Value

    JEGS 86065

    While not as powerful as our top pick, we love the JEGS Portable Generator as a value buy. It’s hard to find value in the world of generators, but this one is fantastic. With 5,000 starting watts and 4,250 running watts, you will be able to enjoy up to nine hours of runtime on a full tank of gas with this generator. You will have to watch this product more closely than our top pick, as it does not come with any form of auto shut-off.

    As far as generators go, it’s hard to beat the price and quality of this JEGS offering, which is why we think that it is the best 5,000-watt portable generator for the money.

    There have been consumer reports of this generator showing up in rough shape or not working at all. Fortunately, it comes with a two-year warranty, and the customer service staff is wonderful. To have your warranty honored, you will need to route it through the manufacturer.

    • Rough delivery

    3. Honda Portable Generator – Premium Choice

    Honda 660530

    This is definitely a premium choice, but you won’t be disappointed in the slightest. This comes with everything you could want in a portable generator. At 230 pounds, it’s a bit heavy, but that’s understandable when you consider how much power it is packing.

    This generator, while not technically recommended to back up your whole house, could do so if need be. With that said, this product is wonderful for camping, tailgating, or the job site. For warranty information, you will want to contact Honda.

    • Can back up your whole home
    • Pretty heavy for a portable generator

    4. A-iPower Gas Portable Generator

    A-iPower AP5,000V

    This company is well-known, but they still put out a wonderful product. If you are looking for a generator that can run a few hours longer than industry standard, this just might be the one for you! With a four-gallon tank, this generator can run up to 12 hours. The alternator itself is what A-iPower calls a “high performance” alternator, which leads to greater peak wattage. This also means that motor-driven appliances and tools can be used at the same time. If you are the camping type, then this is a great generator for you, as it comes fully RV ready. The engine is a four-stroke manual start.

    While many people love their A-iPower generator, sometimes it gets delivered missing a wheel. Yikes!

    • Runs up to 12 hours
    • High-performance alternator
    • Appliances and tools can run at the same time
    • Can have missing wheels!

    5. WEN 56500 RV Portable Generator

    WEN 56500

    WEN is a well-known company in the world of generators, and this RV-ready generator is one of their more popular products. With little gap between the two, this generator is able to produce 5,000 starting watts and 4,500 running watts. You’ll be able to get about seven and a half to eight hours of runtime when on a half load.

    While other portable generators say that they are portable, that usually means they have wheels but are still quite heavy, but this generator from WEN is different. It has a compact design and a handle kit so it really is portable. This has a four-stroke engine and comes backed with a four-year warranty.

    There have been shipping issues with this item, and let’s just say that WEN’s customer service team is less than stellar.

    • Small gap between wattages
    • Actually portable!
    • Delivery issues
    • Subpar customer service team

    6. Green-Power America Gas Generator

    Green-Power America GPD

    Green-Power gives us a generator with 5,000 starting watts and 3,850 running watts. With a runtime of 11 hours at half load, this is one of the longer running generators not only on this list but also on the market. It also has a manual recoil start with a four-cycle engine. This generator isn’t exactly quiet but runs at 74 dB, which is right around industry standard. It’s aided in portability by solid eight-inch never-flat wheels.

    This generator isn’t the easiest to set up, and if you do it wrong, things could go bad in a hurry. There’s a reason it is number six on this list.

    • 11 hours at half load
    • 5,000 starting watts
    • Hard to set up

    7. Pulsar Dual Fuel Portable Generator

    Pulsar PG5250B

    This is the first dual fuel generator on this list! This generator comes with two gas tanks, one for natural gas and one for propane, and can switch seamlessly between the two. That will fuel the powerful 224cc four-stroke engine, which can power virtually whatever you want! Coming with a fold-down handle and wheels that never go flat, this generator can roll wherever you need to take it. It has a three-in-one digital meter, a low-oil indicator, and more importantly, a low-oil shutdown, so you don’t have to worry about burning your engine out. This also comes with a propane hose and a one-year warranty.

    It’s been rumored that this generator isn’t the easiest to set up with RVs, which isn’t great, considering that portable generators are often used for RVs. The customer service team doesn’t have the best of reputations either.

    • Dual fuel tanks
    • Never-flat wheels
    • Don’t work well with RVs
    • Poor customer service

    8. DuroMax Portable Fuel Generator

    DuroMax XP5500EH

    Another dual fuel engine, this generator from DuroMax advertises itself as “powerful.” We believe them! The engine itself is 7.5HP and 225cc. We are actually cheating a little bit with this product, as it goes just over the threshold of 5,000 watts — it has 5,500 starting watts and 4500 running watts. With that extra little bit of power, you can even use this generator as a backup for your house, but we wouldn’t recommend asking too much of it. However, it works quite well for jobsites and tailgating. This generator is EPA and CARB approved in all 50 states.

    While this product is good, it is hardly portable. The tires are made of Neoprene and usually don’t work.

    • Can back up home
    • 5,500 starting watts
    • Not too portable

    9. Power Smart Portable Power Generator

    Power Smart Portable

    Now this looks like a classic old-school portable generator. With a handle that goes up to your shoulders, you can lug this thing anywhere. It’s surprisingly powerful for its size, with 5,500 starting watts and 5,000 running watts. The gas tank is large, the 7.4-gallon tank will get you up to 11 hours of life.

    While the handle does legitimately make this easier to move, this item is absolutely heavy.

    • 11 hours of life
    • Very heavy

    Buyers Guide

    Buying a portable generator is expensive, so this isn’t a decision to make lightly. What are a few things you should consider when buying a portable generator? Let’s take a look.

    Home back-up

    If you are backing up your whole house, there are generators on this list that can do it, but they will need to be monitored. You could opt to buy something with more wattage, with transfer switches and auto shut-offs, but that will inevitably be more expensive.

    The ball game

    If you are bringing your generator to tailgate, then you’ll probably want one of the more portable options that gives you a long runtime, like a dual fuel model.


    Certain generators are made specifically for RVs. Make sure to check the specs to see if the one you want is designed for that. Sometimes, it’ll even be written in the name.


    These products come with all sorts of different warranties, with customer service staff of varying levels of helpfulness. It’s a good idea to look into these things more in-depth, as good customer service teams are important when making such a big purchase.


    There is certainly a great deal to consider, but we hope that our expertise has powered you to find the right generator for your needs. What do you think you’ll go with? Our top pick from Champion is wonderful, and you can’t go wrong with the value of the generator from JEGS. Whichever one you choose, we’re glad that we could help, as we always love generating goodwill.
