8 best outdoor generator accessories

Outdoor generator accessories are items and products designed to enhance the functionality, safety, and protection of portable generators used in outdoor settings. These accessories can help you make the most of your generator while keeping it in good condition. Here are some common outdoor generator accessories:

  1. Generator Covers: Generator covers are essential for protecting your generator from outdoor elements like rain, snow, dust, and UV rays. They help prolong the life of your generator and keep it clean.

  2. Extension Cords: Outdoor-rated extension cords are necessary to connect your generator to appliances or devices that need power. Make sure to use cords suitable for the wattage and amperage requirements of your generator.

  3. Transfer Switches: A transfer switch is a critical safety accessory that ensures safe and proper generator operation. It allows you to connect your generator directly to your home's electrical panel, preventing back-feeding and protecting utility workers during power outages.

  4. Wheel Kits: Some generators come with built-in wheels, but if not, you can purchase wheel kits that make it easier to transport your generator across uneven outdoor terrain.

  5. Generator Fuel Stabilizers: If you plan to store your generator for an extended period, adding a fuel stabilizer to the gasoline or diesel fuel tank can help prevent fuel degradation and carburetor clogs.

  6. Cold Weather Accessories: In cold climates, generators may need accessories like cold weather kits, battery warmers, and block heaters to ensure they start and operate reliably in low temperatures.

  7. Parallel Kits: For those who need more power, parallel kits allow you to connect two compatible generators together to double your power output.

  8. Remote Start Kits: These kits enable you to start and stop your generator from a distance, which can be convenient in adverse weather conditions or if you need to power your generator in an emergency.

  9. Noise Reduction Accessories: Mufflers and noise-reduction kits can help reduce the noise produced by your generator, making it more suitable for campgrounds or areas with noise restrictions.

  10. Maintenance Kits: Regular maintenance is essential for the longevity of your generator.Maintenance kits often include items like oil, spark plugs, air filters, and fuel filters to keep your generator running smoothly.

  11. Security Locks and Cables: Protect your investment by securing your generator with locks and cables to deter theft.

  12. Fuel Cans: Extra fuel cans are handy for storing additional fuel for your generator during extended power outages or outdoor adventures.

When choosing outdoor generator accessories, ensure compatibility with your specific generator model, and follow the manufacturer's guidelines for installation and use. These accessories can help you get the most out of your generator while ensuring safe and reliable operation in outdoor environments.

User questions & answers

Question: So this has a ground (green) from the plug to the box. So do i not have to run a ground to my ground bar in my panel
Answer: Did you measure the opening when in the locked position? In the maximum locked position, it is assumed there will be a full thread length in the handle screw adjustment section - if you adjust past having a full thread purchase the tool may fail. I think it would be dumb to use such a small tool on any material that wide. The answer is 1 1/8" in the locked position at the tip of the jaws - note the jaws would not be parallel and the lower point of the jaw spread would be smaller at about 7/8".
Question: Can this be used if using the 50 amp 4 prong plug on the generator? Or would I need a 4 prong inlet box
Answer: Yes made in the USA and the best pair you'll find mine are great I use them every day
Question: Is the twist and lock generator cord compatible to this inlet
Answer: Yes, I am very satisfied with its conductive effect when I work with locking pliers, and the surface of the vise is frosted so that it will not stick to things during use, you can use it safely.Good luck!
Question: How to punching the hole in the Knockout
Answer: The locking pliers with wire cutter is made of CR-V material,with high hardness,not easy to wear and with a rubber handle,which is anti-skid and wear-resistant.The lever principle design is adopted,so the working process is very labor-saving.

Question: How much watt is the maximum working power of the Power Inlet Box
Answer: Throat depth is 78mm, max jaw opening is 93mm

Answer: Made in China
Question: hi, what is the size of the product
Answer: The wire cutting jaws are located behind the gripping jaws. They are only about 3/8" long and meant for cutting small (#10 gauge or less) wires. If you are cutting only electrical (copper) wires, buy yourself a quality pair of electrical pliers that will last your lifetime when used correctly (no cutting stainless or other hard wires). Irwin changed the excellent original Vice Grip to a clumsy, heavier, not quite piece of junk.
Question: Is the installation hard to accomplish
Answer: The country of origin for the Irwin 5WR-3 is China.

User questions & answers

Question: Can this cord be used in the rain
Answer: This seat fits only John Deere mowers. Please check the bolt pattern before ordering. Unfortunately we do not offer seat for exact your model.
Question: Does this cord provide fused/breaker 15 amp protection on each of the 3 outlets

Question: Is this cord UL listed
Answer: Hello AnthonyThank you for your email This seat should work for your L130 as its listed as fitting.You can compare the bolt mounting pattern on our Amazon Listing just to see if it matches yoursbest regardsRick
Question: The product information says (l5-30p to three 5-20r) but the second picture on the left says l5-30r? description is confusing.i need it to be l5-30r
Answer: Mine was shipped by Amazon's Smiley trucks (not FedEx or UPS or even the USPS) so it doesn't indicate a return address; therefore I don't know where it actually was shipped from. It was in a lightweight cardboard box inside a larger bubble wrapped lined envelope... That seemed good enough to protect it from shipping damage... I got mine in September of 2019 so I can only speak to the one occurrence from 16 months ago... If you order again I hope your experience matches mine.

User questions & answers

Question: My generator out put is 120/240v 30a locking outlet but i need to plug into 50amp transfer switch. can i just attach this to a 30 amp cord
Answer: These will lock onto your lid if there is a tab . Channellock pliers may be a better way to go as they will grab and you can turn .
Question: when my item will be shipped
Answer: I'm not an Irwin rep or anything, but from what I can tell, the 4WR means it's a 4" General Purpose Curved Jaw type. The general purpose pliers have a wire cutter in the jaw, as opposed to some of their other models which don't have one. The 4" model is quite small ... handy for keeping in your briefcase or pocket and useful for getting at small hardware in tight places, but if you're looking for a standard sized set of vice grip pliers, this isn't it.

User questions & answers

Question: Does this fit the Firman H03651 generator
Answer: These boxer briefs are packaged by Hanes as and sold in a five-pack. Different sellers use different terms when listing things in their own systems. This is all well and good, until inventories get uploaded and Amazon assumes they're different things.
Question: is this item waterproof or just water resistant
Answer: Yes. But these were nothing but holes within a month or so. I don’t know if we got a bad batch, or what, but these were garbage.
Question: Will this fit a 3650/4550 Firman
Answer: Yes they are. But that is not the fault of the Vietnamese. Hanes is responsible for quality control. The quality of these was OK but the fabric seems to be getting thinner and thinner each time I purchase them. I would rather pay more for thicker cotton. I may switch to another brand if the cotton gets any thinner.
Question: the specs say up to 25" and my firman, model p03601 for amazon, and p03608 for costco, is 27". it should fit, but does it? all other spec match
Answer: The mesh is woven tightly, not what you typically think of mesh.
