How big of a generator do we need to power our house-is this a question many of us want to know?

Considering this problem, household generators are limited, and their use and purpose need to be carefully considered. 

There are many battery generators to choose from, even if you may not think you are the one who needs them.

However, if your house is out of power for a long time, you will need some equipment that can provide enough power to keep the house running for a long time.

If you are considering buying a household battery-powered generator for this reason, there are many factors to consider.

How to choose a battery generator 

Choosing a battery generator for your home is not as easy as it sounds. There are many factors to consider, such as power output, generator quality and safety.

It will be the best if you take the time to weigh your options and make the best decision based on your needs.

1. Indoor generator VS. Outdoor generator 

For household generators that can be used during power outages, there are many options to choose from.

For most people, the best generator is an indoor generator. These generators are generally quieter and more efficient than outdoor generators, are easier to use in smaller spaces, and can be used with small fuel tanks that are usually used with portable generators.

However, outdoor generators are usually more powerful and more efficient. They usually also require large fuel tanks to generate enough power.

Choosing an indoor generator or an outdoor generator depends on many factors, including your family's specific needs, budget, and preferred location.

There are many good reasons to use indoor generators, but the main reason is that they are generally cheaper. Various other benefits can make it worth the cost.

If you are looking for a household battery generator, make sure it has enough power to meet your needs, including cooking and heating. If you need an outdoor generator, make sure it is weatherproof and easy to transport.

2. Power supply and battery size

One of the most important decisions you make when buying a battery generator is power and battery size. Some people have more gadgets and appliances than others-some people want to power the entire family, some people want to power the refrigerator.

The size of the generator should depend on the type of purpose you plan to use it for.

For example, if you want to keep your home energized in an emergency, a small generator is enough. If you plan to camp, then you need a larger campground. When you know the size of your home and how many people will use the generator, you can determine which type of battery to use.

3. How much electricity is needed

When deciding whether a battery generator is suitable for your home, it is important to remember that you need electricity to charge the battery.

Some battery generators, even if they are large, can take several hours to charge. When you are not using the generator to power your equipment, how much electricity you need at home is also important.

It is important to choose the best battery generator for the family.

First, you need to know how much power you need. If you have a large family or host many people at home, you need a larger capacity unit.

4. Your budget 

When buying a battery generator, budget is critical. When you have other financial needs, you don't want to overspend. Although you can find generators that provide low-cost electricity to your home, they may not be the best choice for power outages and emergencies.

Before buying, please consider your budget and make sure that the device is compatible with your lifestyle. There are different price ranges for household battery-powered generators.

Some high-tech models cost more, but can easily power your home during a storm, while some low-end models usually only work for about four to six hours to charge.

Before replacing the battery, it is best to consider how long the battery can be used under normal use.

5. How often do you charge

If you are planning to buy a battery generator, it is important to know how many times you will charge the battery.

This can be done by measuring the charging time of the product and the type of device it will charge. It is important to consider the number of times the battery generator is charged.

For example, if you are looking for a battery generator that can charge 1,000 times at the average (US) electricity price, you will spend $2,000. On the other hand, if you want to charge 500 times at the average (US) electricity price, your total cost is $1,250, which is better than the first option. 


Refrigerator, kitchen devices such as kettle, toaster, blender, coffee maker, rice, cooker, laptops, phones, lighting, etc. 

  • Smartphone(10w): 175-200 times
  • LED Light bulb(20w): 75-85hrs
  • Television(75w): 20-22hrs
  • Electronic Tools(80w): 19-20hrs
  • Refrigerator (90w): 17-19hrs
  • Slow cooker (200w): 8-9hrs



There are two types of battery generators that you can choose from lithium-ion and lead-acid.

Lithium-ion batteries can be great because they have a longer life span, but they're typically much more expensive.

The lead-acid batteries have a lower price but typically work for less time than lithium-ion batteries.

If you want to save money, it's best to go with a lead-acid battery generator.

However, for a regular house, you need approximately 21kWh per day. Let's say you want to cover the basic household needs for that individual house; that means your battery generator would need around 4-500 watts of power.

If used for 100 hours per year, the average service life of a portable generator will be between 10 and 20 years. Moisture and dust will shorten the life of portable generators. Therefore, it must be properly preserved and maintained.
