Why generators get stolen during outages

When the power is out, a running generator is easy to find. It's loud, it's often the only light on the street, and it sits outside where anyone can reach it. Portable units have wheels or handles because they are built to be moved.

You can't hide it, and you can't bring it inside while it runs. So the goal is to make it slow, noisy, and visible to take.

Chain it to something that doesn't move

Use a hardened steel chain and a lock rated for outdoor use. Thin cable can be cut with hand tools, so treat it as a backup layer, not the main one.

Run the chain through a solid part of the frame. On open-frame units, that's usually the tubular steel frame. On enclosed inverter units, look for a molded handle or frame point that is part of the main structure. If the handle is held on with a few bolts, a thief may be able to remove it and leave the chain behind.

Anchor the other end to something fixed. A ground anchor bolted into a concrete pad is the strongest option. A sturdy post set in concrete also works. A fence rail, a deck railing, or a tree branch is weaker than it looks.

• Keep the chain tight so it can't be used for leverage
• Lift the lock off the ground so it's harder to smash or pry
• Check that the chain doesn't touch the muffler or exhaust area
• Ask a contractor about anchor bolts if you're unsure about your concrete

Place it safely, then make it visible

Safety comes before security. Set the generator outdoors, well away from doors, windows, and vents, with the exhaust pointed away from the house. Follow the owner's manual for clearance distances. Never run it in a garage, carport, shed, or under a covered porch, even with the door open.

Within that safe zone, pick a spot you can see from inside. Battery-powered motion lights and a camera help a lot. If you use a cover or enclosure while it runs, use only one the generator maker allows for operation, since blocked airflow can cause overheating and fire.

• Install battery-operated carbon monoxide alarms inside the home
• Keep the area around the generator dry and clear
• A motion light on a separate battery keeps working if fuel runs out

Protect the fuel and the paperwork

Spare fuel can also be a target during long outages. Store spare gasoline or propane in a locked, ventilated spot away from the house, following local fire rules and the maker's guidance. A dual fuel unit lets you switch fuels, so secure both supplies.

Before an outage, photograph the generator from several sides and take a clear photo of its serial number label. Save the receipt with your homeowner's or renter's insurance records. Some owners engrave their name or a code on the frame, which may make a stolen unit harder to resell.

Choosing a generator that's easier to secure

When you compare models, look at the frame, not only the output. Find a point a chain can pass through that is part of the main structure. Check the owner's manual or the maker's spec page for weight and wheel design, since a light unit on wheels needs a stronger anchor.

The listing on this page, the Champion Dual Fuel RV Ready Portable Inverter Generator, is an enclosed inverter unit. Before you buy any model, check where its handles attach and plan your lock point. Also check its separate running and starting watt ratings against your own loads, because the wattage in a listing name is not the continuous output.

If you want to connect a generator to your home's wiring, a licensed electrician must install a transfer switch or interlock. Check the generator's outlet type with your electrician before buying, since the full connection has to suit your installation.
