Buying Guide to the Perfect Generator for 15000 BTU Air Conditioner

Looking to buy a generator for your BTU A/C? Here are a few factors you need to pay attention to.

I) Portability

One thing that you should know about living in an RV is that you will be moving around a lot. Therefore, you do not want a generator that will drag you down and complicate shifting from one area to another.

There are several factors that aid in boosting the generator's portability. Some units feature ergonomic handles that ensure you can comfortably carry it around while others have wheels to make the movement easier.

Most of all, ensure the generator is exceptionally lightweight such that you can carry it all by yourself from the RV to the campsite.

II) Capacity

We all know that the BTU air conditioner consumes a lot of power, and it is, therefore, wise to get a generator that can meet this demand. Besides this appliance, there are other equipment in your RV, such as refrigerators and other electronics such as tablets and mobile phones, that will need the generator's power.

Therefore, it would be wise to get a unit with sufficient capacity to handle all these items without being overwhelmed. The ideal power output should be between 2000 and 4000 watts.

III) Run Time

Nobody likes the idea of waking up at ungodly hours to refuel the generator. Therefore, always settle for a unit with a run time of at least 8-hours, and you can rest assured you have enough sleep in the wild.

IV) Noise

The noise levels that your generator gives out is another factor to put into consideration. Even if you place it far away from where the family is resting, there is always the chance that a loud generator could end up annoying the neighbors.

In this instance, we advise that you get a quiet-operating unit and you can know this by checking out its decibels. In general, the lower the decibels, the quieter it is.

V) The Fuel

In most cases, RV generators run on either diesel, gasoline or diesel. Gasoline generators are often the preferred choice due to their ease of use, maintenance, and convenience.

On the other hand, diesel tends to be pricier and maintaining such generators is often too costly.

A: Surge watts refer to the amount of energy required to start large appliances while running watts are simply the need to run your devices continuously. It is advisable to get a generator that can handle both requirements comfortably.

Q: What noise level is the best for these generators?

A: First, it will all depend on where you intend to use the unit. If it is a large open area, you could place it far away, where it would not disturb you or your loved ones no matter how loud it is.
