Power Stations

Review of the Best Portable Power Station Brands of 2021

Sometimes you don’t need a big generator to power your essential appliances. Whether on the go or in your home, you simply need electric power (during an outage) to run your most-used devices, such as your mobile phone, laptop, emergency lights, medical equipment (think CPAP machines), and other small electronics. 

For such scenarios, running a fuel-based portable generator can be costly and might seem unnecessary, especially if it’s only for personal use. In such situations, a more viable option is to invest in a portable power station – there are many to choose from on the market.  

Portable power stations, also known as “power banks,” are lightweight, compact, safe to use indoors, portable, and easy to manage. They provide instant power in a heartbeat with no complexities or challenges of running a generator  (think about moving a generator around or refueling it).

Finding the best portable power station isn’t always easy. In fact, if you’re unfamiliar with all the brands out there, it can be a downright challenging task. There are hundreds of models from tens of brands to sift through, and you may start thinking that they’re all one and the same. 

When searching for the right one for you, it’s not just a case of selecting an affordable power station; you have to check the brand’s reputation and ensure that the product specs meet your specific needs and requirements. If the brand doesn’t have a good reputation, how can it provide you with a quality portable power station?

To help you find the best power station for you, we have tested and reviewed several top models from six leading power bank brands. Apart from the reviews, this article will also walk you through a helpful buying guide complete with safety and operational instructions and a FAQ section.

Here are the best portable power stations from the top six brands available in 2021.

Portable Power Station Buying Guide

A buying guide helps make the best purchase decision when shopping around for power banks. As you have gone through the reviews, you may have a couple of options in your mind by this time. However, before finalizing your purchase decision, it is better to go through a buying guide. Our buying guide is focused on the main features of portable power stations and will help you avoid making the wrong decision.

How to Choose the Right Portable Power Station for You?

Let’s go through all the features mentioned below, and you will be able to choose the right power station.

Power Output

The most important thing while deciding the power output of a portable power station is how much power you need. You can’t run heavy machines on a portable power station, but calculating your power needs is still the right approach. Make a list of your phone and laptop chargers, mini cooler, drones, mini lights, fans, or any other appliances you can power on a portable power station. Once you have the right figure with you, you can select the appropriate power output.     


Check for the battery capacity and lifecycles before buying the portable power station. The lifecycles determine the total life of the battery, and the capacity controls the backup time. While lead-acid batteries also work great, it is best to choose lithium-ion batteries because they give better backup, are lightweight, and last longer.     

Recharging Time and Recharging Modes

Some units can be recharged in under an hour from AC outlets. They are a blessing for the user. Make sure you look for a versatile device when it comes to recharging modes. More recharging modes in a power station make it user-friendly. Some models come with MPPT controllers, which reduce the solar charging time.  


What’s the point of owning a portable power station when you have to attach additional connectors with it for connecting different appliances? Hence, it is best to go for a power station which offers maximum and latest outlets. It must come with a USB-C outlet, AC outlet, DC outlet, and simple USB port.    


Look for a power station that offers maximum safety features. Almost all the brands reviewed above provide excellent safety features in their power banks.   


A portable power station must be easy to carry along with you. It must come with a comfortable and ergonomic carry handle. Make sure that there is enough space between the handle and the unit’s body so that you can grip it comfortably.   

Warranty and Certifications

Warranty and certifications bring peace of mind. Power stations can develop issues from out of nowhere, which means that a warranty is compulsory for such products. Certifications ensure that there is no harm in using it indoors and in closed camps.   

Special Features

Look for special features like power boosts, ultra-fast charging, LED lights, and SOS features. They enhance the value of the money and make the power station versatile.

Portable Power Stations Safety Tips and Usage Guide

Because portable power stations don’t need fuel to produce electricity, they are very safe devices. However, because of careless usage, things can get out of hand. Hence, you must follow all the safety precautions outlined in the devices’ user manual/safety leaflets. We have listed some of the general safety and usage instructions regarding portable power stations that you must follow all the time.

  • Never operate/use your device in the open air while it is raining or snowing.
  • Avoid direct contact with sunlight as much as possible.
  • Don’t overload or drain the battery completely.
  • Never try to repair or replace the unit by yourself.
  • Don’t connect appliances not supported by the device.
  • Keep an eye on your power station and notice overheating, unusual sounds or anything out of order.  
  • Always store your device at room temperature in a dry and safe place.
  • Follow the manufacturer’s instructions at all times.

How do power stations generate electricity?

Portable power stations store the charge in the batteries. When you connect an appliance with them, the stored power/charge is used to run your appliances. Once the battery is drained, it will need to be recharged to work again.

How long will a portable power station run my devices?

The running time depends mainly on two factors; the power station’s capacity and the wattage requirement of your device. Typically, a device falling under the output of a power station can last from 2-12 hours.

Can I charge my power station while using it?

Yes, only if it has a pass-through charging feature.

Can I take my portable station on a flight?

No. Commercial airlines don’t allow carrying portable power stations in your checked luggage. However, if you have a power bank under a certain capacity (check the allowances with the airline), you can take your power bank onboard the flight with you (in the cabin).

How many devices can I charge at one time?

It depends on the type of devices, the power output of the battery, and the number of outputs on the power station.  

Which is the best portable power station?

All the power stations reviewed above are best in their respective categories. However, Jackery, EcoFlow, and Rockpals are at the top.

Which is the best power station brand?

Jackery is the most technologically advanced brand, DeWalt is the oldest and most trusted, Bluetti offers special features, and RockPals come with impressive outlets. Picking the best brand out of the 6 reviewed in this guide is a tough call, and we rest our decision with Jackery.

What is the price of a power station?

The price of a power station varies from $200 to $600. If there are extra features like a jump starter and with air compressor, you may have to pay more for it.

What is a good capacity for a portable power station?

The capacity of the power station must be picked while considering its power output. For example, if the output is around 200 watts, you can go with a capacity of 240Wh. For higher outputs, look for batteries with a capacity of 300Wh or above.

Are portable power stations safe to use?

Yes. Portable power stations are safe to use compared to portable generators.
