Best Portable Battery Generator To Buy In 2021

Generators have been in use for a long time as power backup devices in case the mains go down. Other people have used it in other cases such as remote cabins or when out on the trails. However, traditional gasoline generators do not do the best job at these kinds of use cases. They are bulky and extremely loud to begin with. Even the quietest of gasoline generators are unbearable at close range, which is where you want your portable generator. They also produce fumes that make it uncomfortable to be around and they pollute the environment too. 

Portable battery generators have now become the norm because they literally have none of the drawbacks traditional generators do. They are quiet, portable, powerful and do not generate any fumes, hence no polluting the environment can even be used indoors. Finding a solar powered generator that fits your needs can be difficult. We all want the best solar generator, but it might be quite hard to make the best decision since there is a lot. Fear not because we got you covered; we have prepared a list of 10 portable generators to suit almost anyone’s needs. However, before that, these are the important factors to consider before making your selection.

Things to Consider When Buying A Portable Battery Generator

How Long Does It Last?

It is important to have a huge capacity battery that can last long. Also, it is best to choose ones with lithium batteries as they are usually light and last longer.

What Does It Come With?

The accompanied accessories are crucial to consider. Some portable battery generators have many accessories to accommodate different devices while others don’t. Some have all chargers included while those without can be bought later.

Ease of Use and Convenience

Because this is a portable device, it needs to be easy to use and set up. Look for devices with simple inputs and LED/LCD displays if possible for easy monitoring and operation. Also, look if they have carrying handles because those are really important for something labeled as portable.

Battery Charging Options

A good portable generator should have at least two charging options; solar and AC plug. However, three is best, allowing you to charge using other DC sources such as in your car. This affords you much more flexibility should the portable battery generator die.


Consider the build quality of the device (plastic or metal construction) and look into other customer reviews on Amazon or eBay. Also, a good portable battery generator should have BMS (battery management system) to prevent the batteries from wearing out prematurely or even exploding from overcharging. A good manufacturer warranty is extremely crucial.


A good portable battery generator needs to be powerful enough to power the devices you require it to. If you are only powering small devices such as laptops and phones, it is no big deal. However, if you want to power AC equipment such as a small fridge, having a powerful pure sine wave inverter is very important.

Anker is a name that is known in the industry for its quality products.

It is very light and compact, allowing it to be easily moved around. The Anker Powerhouse features a 434Wh lithium battery for all your outdoor camping devices. With the Anker powerhouse, you can charge your smartphones, laptops, action cameras and slightly power-hungry devices like coolers or small electric stoves for the ultimate outdoor experience. 

One of the downsides of the Anker powerhouse is that it is only rechargeable through a wall outlet. It takes 10 hours to fully recharge, so make sure you have the time to charge, preferably overnight or when away at work or school before a weekend trip. It can be used to charge many devices (up to 40) once it is full, so if it’s a couple weekend out or a small family, it can sustain you over the weekends. Whether you are in the great outdoors, or in your home, Anker made sure you will not run out of power and remain connected.
