You might be wondering, “What does all of this mean?”. If so, here are a few things you should know about portable generators.

Portable battery chargers are essentially giant rechargeable batteries.

They typically feature a few different types of charging outlets and can be recharged by a standard AC in wall socket.

Portable generators can be easily moved, unlike standby generators.

The industry rates the best portable battery generators based on the amount of power they produce, referred to as watts.

The more watts a generator can produce, the more electronics can be supported by it.

The primary advantages portable battery chargers hold over gas generators include:

  • Less noise
  • No emissions/ Environmentally Friendly
  • More utility/ flexibility(i.e. personal devices, medium appliances)
  • Compactness
  • Portability
  • Convenience



What Stats to Look For:

When browsing the web for the best portable battery generator, you’ll likely encounter terms you don’t understand.

Here’s a comprehensive yet simple explanation of all the terms you may encounter:

  • Watts: The Watt is a standard unit of power used to measure how much electrical energy is being produced. The more watts a device uses, the more power needed to support the device.


  • Watt-hours: A unit of measurement for power over time in hours. For example, a 100-Watt light bulb powered by a 400 Watt-hour battery will last for 4 hours. More Watt-hours means larger devices can be charged for longer periods of time.


  • USB Port: A USB port is a cable connection that supplies small personal devices with power. These can be found on the sides of laptops, and are most commonly used to handle flash drives and charge smart phones, cameras, etc.


  • AC Port: A common power plug that’s used to power most large devices. Can be found in the walls of buildings and homes.


  • DC Port: A less common power plug typically used to power hand tools.

Best Portable Battery Generator (2021) — Buyers Guide

At this point, I’ve covered a vast amount of information to help you find the best portable battery generator for your specific needs and budget.

Now it’s time for you to evaluate exactly what you’re looking for. Ask yourself:


Why do I need a portable battery generator?

What will I use it for?

What specific traits are you looking for?


There are a lot of factors that go into an important tech purchase like this. Take some time and answer these questions on your own.

Now, we’ll take a look at some frequently asked questions (FAQ) and respective detailed answers to ensure you find the best portable battery charger.

How do I know if a generator is priced fairly?

The price of a portable battery generator is most commonly based on its output in Watts, a unit of power. Typically, the price will be very close to the device’s watt output.

Take the Jackery Explorer 240 for example. The price is about $249.99, which is an overall fair market price.

When shopping for a portable battery generator, always pay attention to this fact.

 If a battery generator’s price is way beyond its output in Watts, it’s probably too expensive.

If a generator’s price is below its watt output, it may be poorly designed, or have a lower watt output than the seller claims.

Another factor to consider is any special features the product may have. Some, for example, have flashlights or built-in wheels and handles.

If the product has some special features, expect the price to be significantly higher than the wattage.

What is a Pure Sine-Wave Inverter in Portable Generators?

You might see some portable battery generators advertise that they use a Pure Sine-Wave Inverter.

This simply means that the electricity output by the battery won’t damage the device that it’s charging.

Pure Sine-Wave refers to the frequency at which electricity is transferred from the battery to the device it’s charging.

With a Pure Sine-Wave, electricity will be smoothly delivered without overcharging or “frying” the battery of the smaller device.

How do I ensure that my generator is durable?

Durability and safety are important factors especially when using a portable battery generator outdoors.

For example, if it rains while you’re using your portable generator, you’ll have a dangerous electrocution problem on your hands.

Depending on your intended use for the generator, check for certain specifications that pertain to hazards you may encounter while you use the product.

If you’re bringing your generator to a campsite, see if the generator has a waterproof feature, or bring something to cover it in the event that it rains.

If you’re running your generator in a hot environment, make sure that it has a cooling mechanism to ensure that it doesn’t overheat.

Consider the circumstances in which you’re planning to use the generator and look for features that will ensure your safety and protect the generator from damage.

If the generator you want doesn’t have the right protective features, take some steps on your own to ensure safety.

What are battery lifecycles?

A lifecycle refers to how long batteries can function and maintain their intended capacity. Using a battery from 100% to 0% capacity indicates one whole cycle.

Depending on the chemistry of a battery’s composition, you can expect different lifespan lengths from battery to battery.

For example, Lead-based batteries typically have 200-300 cycles, while Lithium-ion batteries tend to work for 500-800 cycles.

Depending on how long you intend to use your battery, pay attention to the chemical composition of the battery.

Look for the Lithium-ion battery if you plan on using the battery generator for a significantly long time.

If you only need a battery generator for a short period, don’t worry too much about this factor.

Typically, Lithium-ion batteries will cost more because of their long lifecycles.

Balance how much you want to spend with how long you intend to use the battery, and it should be easy to decide the best portable battery generator for you.

What’s the cheapest best portable battery generator?

If you’re looking for a budget friendly battery generator that’s also quality, I recommend the NEXPOW Portable Power Station.

This generator is a steal at only about $99.99 on Amazon. It’s a surprisingly quality product despite its modest price.

Beware of buying products that are too cheap and always buy from trustworthy sellers.

Portable battery generators are complex devices and need to be manufactured with care. If not, they could be defective and possibly dangerous.

Price isn’t an issue. What’s the most powerful battery generator I can buy?

If you’re looking for raw power, and you’re not on a budget, I recommend the MAXOAK Power Station. It is not on my list just because of its price and bulky size, which makes it not that portable actually.

This portable power station costs about $1999.99 and delivers a whopping 2400 watt-hours for devices up to 1000W. This device is the definition of heavy-duty and in my opinion, it’s worth every penny.

It’s incredibly durable and has some of the most powerful output in its class. With 4 USB, 2 AC, and 1 DC outlet, this powerhouse of a battery generator can power you, your family, and your friends comfortably for a significant period of time.

The only downside about this product is how big and bulky it is. Weighing in at 48.5 lbs., this battery generator would be incredibly difficult to carry over long distances.

If, however, you manage to move this beast of a device to your destination, know that all of your charging needs will be met.

Why would I need a portable battery generator?

If you’re on the fence about buying a portable power station, here’s a few things you should think about.

Do you go camping frequently? If so, how long do you camp for?

Do you spend a lot of time outside, or host outdoor events such as barbecues/ parties?

Do you travel frequently? Or do you constantly find your devices out of battery with no wall outlet available?

If you answered YES to any of those questions, I strongly suggest you purchase a portable battery generator.

Portable battery generators are essentially charging power stations for all of your personal devices. They come in many shapes, sizes, and prices, so it won’t be any trouble to find the perfect one for your needs.

If you’ve been camping recently, you may be familiar with the inconvenience of returning to your car every time you need to charge your phone.

With a portable battery generator, this isn’t an issue. You can charge several devices many times during your camping trip, so you’ll never have to worry about your phone dying before getting that awesome picture.

If you have a lot of people over at home for a backyard barbecue or a party, it’s inevitable for phones and other devices to run out of battery. A portable power station is the perfect solution for keeping everyone’s devices charged.

If you embark on road trips often, keeping your phone charged for navigation and/or music is very important. If your car isn’t equipped with a car charger, this can quite a problem.

With a small, compact portable battery generator, this problem is a thing of the past. You can even charge all of your passengers’ devices simultaneously.

Essentially, there are endless ways that you could use a portable battery charger in your daily life.

Whether you’re on a tight budget or endless budget, looking for something to charge your phone or power your TV, there will be a portable battery generator for you.
