Generators and power
Which generator size do I need?
Add up the running watts of everything you want to power at the same time, then allow for the extra starting watts of anything with a motor, such as a refrigerator, sump pump or air conditioner. Every product page lists the starting and running watts. Email us your list and we will help you choose.
Inverter or conventional portable generator?
Inverter generators produce clean, stable power that is safe for laptops, phones and other sensitive electronics and they run quieter and more efficiently. Conventional portable generators give you more watts for the money, which suits home backup and job sites.
Can I connect a generator to my house?
Only through a transfer switch or interlock installed by a licensed electrician. Never back-feed a generator through a wall outlet. Home standby generators, such as the Generac models we carry, include a transfer switch and must be installed by licensed professionals.
Can I run a generator indoors?
Never run a gas generator indoors, in a garage or near windows, doors or vents: exhaust contains carbon monoxide. Battery power stations from EcoFlow and EGO have no fuel or fumes and are safe to use indoors.
Do generators arrive with fuel and oil?
Generators ship without fuel. Some models include engine oil; the product page and the manual list what is included and what to add before the first start.
Which generator brands do you carry?
Generac, Cummins, Kohler, Briggs & Stratton, Champion Power Equipment, Westinghouse, DuroMax, Firman, Honda, Yamaha, GENMAX, Pulsar, A-iPower, Simpson and Kubota, plus power stations from EcoFlow, EGO and Anker.
Lawn mowers
Do your robot mowers need a boundary wire?
Most don’t. The Mammotion, Navimow and Husqvarna EPOS models (Automower® iQ series and CEORA®) use RTK satellite, LiDAR or vision positioning instead of a perimeter wire: you map the lawn and set zones and schedules in the manufacturer’s app. The Husqvarna Automower® 435X AWD works with a boundary wire around the lawn edge. Each product page says which system it uses.
Which mower fits my lawn?
Each product page lists the lawn size, cutting width and runtime. Robot mowers are rated by lawn area, from 1/4 acre up to 6 acres, and cordless mowers by acreage per charge.
Are batteries included with cordless mowers?
Kits include batteries and a charger; tool-only listings do not. The Included line in each product’s specifications shows exactly what is in the box.
Which mower brands do you carry?
Husqvarna, Mammotion and Navimow robot mowers, and cordless and walk-behind mowers from RYOBI, Milwaukee, DEWALT, Makita and ECHO.
Products
Which Keter sheds do you sell?
We carry the Keter Stronghold, Cortina, Darwin, Manor and Signature Collection lines, all brand-new. We never sell off-brand or private-label substitutes.
Which shed size do I need?
Answer three quick questions on Find my shed, or compare real footprints in our shed size guide. Measure your space twice and allow room around the shed for the doors and for assembly.
Shipping and delivery
Is shipping really free?
Yes. Every price includes delivery to the 48 contiguous states and Washington, DC. Nothing extra is added at checkout.
How fast will my order arrive?
Orders are processed within 0–24 hours and usually arrive within 2–5 business days after shipping. You receive tracking by email as soon as your order ships.
How is my order delivered?
Sheds travel by guaranteed LTL freight, generators over 150 lb, yard equipment and garden fountains by expedited LTL freight, to your curb or driveway. Lawn mowers, power stations and portable generators come by UPS Ground or FedEx Ground to your door. Every option is free and arrives within 2–5 business days. See shipping and delivery.
Will the freight driver bring it inside?
No. Freight is delivered to your curb or driveway and drivers are not required to carry items onto your property, so please have someone available to help with the heavier boxes.
How do I track my order?
Use the tracking link in your shipping email, or enter your order number and email on our order tracking page.
Do you ship to Alaska, Hawaii or outside the US?
Not at the moment. We ship to the 48 contiguous states and Washington, DC.
Assembly
Do I need to assemble it myself?
Most sheds ship flat-packed and need assembly with common household tools. Times and tools vary by model and are listed in the included instructions.
Is there an assembly guide?
Yes. Our assembly and installation guide covers the tools you need, how long it takes, site preparation and links to the official instructions.
Can I return a shed after assembling it?
We may not be able to accept an assembled shed, so please contact us before assembly if you have any doubt about its size or fit.
Returns and refunds
What is your return policy?
You have 30 days from delivery to return an unused item in its original packaging for a full refund. See our returns policy.
Who pays for return shipping?
We do. Return shipping is free and there is no restocking fee. Large items like sheds are collected by a free freight pickup.
When will I get my refund?
Within 5–7 business days of the item arriving back at our warehouse, to your original payment method. Your bank may take a few extra days to show it.

Warranty
What warranty comes with my order?
Warranty terms are set by each manufacturer and every product page lists its exact terms. If a problem comes up, contact us first and we help you with the next steps.
How do I make a warranty claim?
Email [email protected] with your order number, the product and model, a description of the problem and photos. We confirm the next steps within 2 business days and guide you through the claim with the manufacturer. See our warranty page.
