I’m heading out on a camping trip and need a generator. What’s my best option?
That depends on what you’re powering. If you just need to charge phones and run a few small things, an inverter generator is a great choice—it’s quiet and provides clean power for electronics. If you’re running bigger appliances like an A/C unit or fridge, you’ll want something with more wattage, like a dual-fuel generator so you have the option of using gas or propane. And if you want something completely silent, a power station or solar generator might be the way to go!
What’s the difference between gas, propane, and battery-powered generators?
Gas generators are powerful and easy to refuel, but they can be noisy and need regular maintenance. Propane burns cleaner and has a longer shelf life, so you don’t have to worry about fuel going bad. Dual-fuel generators give you the flexibility to switch between gas and propane, which is super handy.
Do I need any accessories for my generator?
A few extras can make life easier. A power inverter lets you run different appliances, plug adapters help connect to whatever you’re powering, and a transfer switch makes it easy to switch between generator and main power. Oh, and don’t forget a weatherproof cover if your generator will be outside—it’ll help it last longer.
How do I figure out what size generator I need?
Think about everything you want to run at the same time—add up the wattage of each appliance and make sure your generator can handle at least that much. If you’re running something with a motor, like an A/C or fridge, remember that they need extra power to start up, so look for a generator with a higher starting wattage to handle the surge. If you’re unsure, etrailer has a generator guide to help you out!
How do I safely use a portable generator?
Portable generators are great for camping, RVing, and backup power, but using them safely is key. You’ll need to place it outdoors in a well-ventilated area, use the right fuel and oil, and never overload it. Want a full guide on how to set up, run, and maintain your generator safely?
