You want your trip to go well, so first add up the total wattage for all your devices. Check the starting and running power for each device. When you pick a mobile trailer generator or a towable generator, choose one that meets or is a little more than what you need. If you want to power an rv or deal with power outages, a mobile generator can help you. Picking an rv generator that fits your rv and power needs makes things easier. Kachai has rv generator choices and mobile generator sets for any trip.


Key Takeaways

  • First, add up the running and starting wattage for all your devices. This helps you know how much power you need before picking a generator.

  • Choose a generator that matches or is a little more than your total wattage. This helps stop power problems and keeps your devices safe.

  • Do not pick a generator that is too big. This saves fuel, makes less noise, and makes travel easier.

  • Add 20% more to your total wattage for safety. This helps with power surges and keeps your generator working well.

  • Pick a generator with the right fuel type, noise level, and portability. Make sure it fits your RV and how you like to travel.


Why Generator Size Matters

Choosing the right size generator for your trip is more important than you might think. If you get the sizing wrong, you could run into problems that spoil your adventure. Let’s look at what happens if you pick a generator that’s too small or too big.

Undersized Generator Risks

If you choose a generator that’s too small, you might not have enough power for all your devices. Imagine trying to run your air conditioner, fridge, and microwave at the same time, but your generator just can’t keep up. You could end up with:

  • Devices that won’t start or keep shutting off

  • Flickering lights or weak power

  • Overheating the generator, which can damage it

  • Tripping the circuit breaker again and again

You want your trip to be smooth, so make sure your size generator matches your needs. If you go too small, you risk damaging both your generator and your devices.

Oversized Generator Issues

You might think a bigger generator is always better, but that’s not true. If you pick a size generator that’s much larger than you need, you could face other problems:

  • Wasting fuel and spending more money

  • Carrying extra weight that makes travel harder

  • Dealing with more noise than necessary

Oversized generators can also be harder to move and store. When you focus on proper sizing, you get a generator that fits your trip perfectly. You save money, reduce hassle, and enjoy your time outdoors.


Sizing Guide for Mobile Trailer Generator

Choosing the right mobile trailer generator for your trip starts with a simple plan. You want to make sure your rv has enough power for everything you need. Let’s break down the steps so you can feel confident about your rv generator choice.

List Essential Devices

First, grab a notepad or your phone. Walk through your rv and write down every device or appliance you plan to use. This step is called "identify your loads." Think about things like your air conditioner, microwave, fridge, coffee maker, TV, and lights. Don’t forget smaller items like phone chargers or fans. If you use a mobile generator for outdoor gear, add those too.

Here’s a quick list to help you get started:

  • Air conditioner

  • Refrigerator

  • Microwave

  • Coffee maker

  • TV

  • Laptop

  • Lights

  • Phone chargers

  • Fans

You want to make sure you don’t miss anything. The more complete your list, the better your sizing will be.

Calculate Wattage

Now, let’s figure out your wattage needs. Look at each device on your list. Check the label or manual for the running wattage and starting wattage. Some appliances, like your air conditioner or fridge, need extra power to start up. That’s called the starting wattage. The running wattage is what they use to keep going.

You can make a table like this:

Device Running Wattage Starting Wattage
Air Conditioner 1,500 2,200
Refrigerator 180 600
Microwave 1,000 1,000
Coffee Maker 800 800
TV 120 120
Laptop 60 60
Lights 100 100
Phone Chargers 20 20
Fans 75 150

Add up all the running wattages. Then, find the highest starting wattage from your list and add it to your total running wattage. This gives you your total power requirements. Sizing a generator this way helps you avoid surprises.

Tip: If you can’t find the wattage, check the device’s amps and volts. Multiply amps by volts to get watts.

Add Safety Margin

You don’t want your rv generator working at full power all the time. It’s smart to add a safety margin. Most experts say you should add at least 20% extra capacity to your total wattage. This covers any extra power needs or surges when you start up big appliances.

Here’s how you do it:

  1. Add up your total wattage needs.

  2. Multiply that number by 1.2 (for 20% extra).

  3. Choose a size generator that meets or slightly exceeds this number.

For example, if your total wattage is 3,000 watts, you should look for a mobile trailer generator that can handle at least 3,600 watts. This way, your rv and all your devices run smoothly, and your generator lasts longer.

Note: Sizing your rv generator with a safety margin keeps your trip stress-free.

If you want a generator that fits your exact needs, check out the Kachai Generator Set. Kachai offers mobile generator options that you can customize for your rv or trailer. Their mobile trailer generator models come with features like integrated fuel tanks, refueling plates, and safety systems. You get a reliable rv generator that matches your power requirements, whether you’re camping, traveling, or using your rv for work.

When you follow these steps, you make sizing easy. You get the right mobile trailer generator for your rv, and you avoid problems on your trip.


RV Generator Buyer's Guide

Choosing the right rv generator can feel tricky, but this rv generator buyer's guide will make it simple. You want your rv to have steady power, whether you’re camping in the wild or parked at a site. Let’s look at what matters most when picking a portable generator or towable generator for your rv.

Fuel Type Options

You have three main fuel choices for your rv generator: diesel, gasoline, and propane. Each one has its own pros and cons.

  • Diesel generators work well for big rvs. They last a long time and use less fuel. Diesel can be easy to find if your rv runs on it.

  • Gasoline generators are common and easy to refuel. Gas is everywhere, but it can go bad if you store it too long.

  • Propane generators burn clean and run quietly. Propane tanks are simple to swap out, but you might need to carry extra tanks for long trips.

Tip: Think about what fuel your rv already uses. Matching your rv generator fuel type can make things easier.

Noise Level

No one wants a loud generator ruining the peace. When you pick a portable generator, check the decibel rating. Lower numbers mean quieter machines. This matters a lot if you camp in quiet places or stay near other people. Many rv generator models now come with sound shields or silent running features.

Portability

You want a portable generator that you can move without a struggle. Look for wheels, handles, and a compact design. Some rvs need a towable generator, which you can hitch and move with your vehicle. Mounting options also help if you want to keep your rv generator in one spot.

Feature Portable Generator Towable Generator
Easy to Move
Needs Hitch
Good for Big RV

Power Output

Check the wattage your rv needs. A good rv generator gives you enough power for all your devices. If you use sensitive electronics, look for an inverter portable generator. These keep the power steady and safe for laptops or TVs. Features like electric start and multiple outlets make life easier.

Note: Always match your rv generator’s power output to your real needs. Too much or too little can cause problems.


Select the Right Generator

Budget Considerations

When you plan your next rv trip, you want to get the most value for your money. Start by setting a budget for your rv generator. Think about what features matter most to you. Some people want a quiet portable generator. Others need more power for bigger rvs.

You should balance cost, features, and durability. A cheaper rv generator might save you money now, but it may not last as long. Higher-quality models often come with better safety features and longer warranties. Make a list of what you need. Do you want electric start? Do you need a portable generator that is easy to move? Write down your must-haves and nice-to-haves.

Tip: Don’t forget to include the cost of fuel and maintenance in your budget. These can add up over time.

A good way to save money is to select the appropriate generator for your rv size and power needs. If you pick a generator that is too big, you pay for extra power you never use. If you go too small, you risk damaging your rv appliances.

Brand and Support

Choosing an rv generator from a trusted brand makes your trip easier. Reputable brands like Kachai offer quality, customization, and global support. You want a company that stands behind its products. Kachai gives you options for different rv sizes and power needs. Their rv generator sets come with helpful features and safety systems.

Look for brands that offer strong after-sales service. Good support means you get help fast if you have questions or problems. A solid warranty gives you peace of mind. You know your rv generator will work when you need it most.

Here’s a quick table to help you compare:

When you select the right generator, you make your rv adventures smoother. You enjoy your trip without worrying about power. Take your time when choosing an rv generator. Pick a brand that supports you every mile.


Calculation Example

Sample Trip Scenario

Let’s walk through a real example. Imagine you plan a weekend getaway in your rv. You want to run a few common appliances. Here’s your list:

  • Air conditioner (for hot afternoons)

  • Refrigerator (to keep food fresh)

  • Microwave (for quick meals)

  • Coffee maker (for your morning boost)

  • TV (for evening movies)

  • Lights (inside and outside)

  • Phone chargers

You want to make sure your rv has enough power for all these. You also want to avoid overloading your generator. This is where knowing your power requirements really helps.

Wattage Calculation

Now, let’s figure out your total power requirements. You check the labels on your appliances and write down the running and starting wattages. Here’s a simple table:

Appliance Running Watts Starting Watts
Air Conditioner 1,500 2,200
Refrigerator 180 600
Microwave 1,000 1,000
Coffee Maker 800 800
TV 120 120
Lights 100 100
Phone Chargers 20 20

First, add up all the running watts:
1,500 + 180 + 1,000 + 800 + 120 + 100 + 20 = 3,720 watts

Next, find the highest starting wattage. The air conditioner needs 2,200 watts to start. Add this to your running total:
3,720 + (2,200 - 1,500) = 4,420 watts

Now, add a 20% safety margin to keep your rv generator running smoothly:
4,420 x 1.2 = 5,304 watts

So, you need a generator that can handle at least 5,304 watts. This covers your rv’s power requirements and keeps your trip stress-free.


You now know how to pick the right mobile trailer generator for your rv. Start by listing your devices and checking their wattage. Add a safety margin so you never run out of power, even during power outages. Look for features that fit your rv and your travel style. Use this guide to make your next trip easy. If you want a reliable choice, Kachai offers great support and custom options.
