Despite its size, the K2 still recharges itself relatively quickly, usually in under 8 hours. And you can charge this power bank while you are using it, which makes it unique among many other competitors.


While the Maxoak Portable Laptop Charger K2 is not for everyone, it is a smart choice for those who need to keep their laptops charged no matter where they are.

Best Portable Power Bank

Buyer’s Guide to Finding the Best Portable Charger Capacity

Power bank capacity is measured in milliamp-hours (mAh). This is a measure of how much power the battery can hold. The more it holds, the more devices you can charge or the more often you can charge your devices without needing to recharge the power bank. In general, larger capacity will result in a larger, more cumbersome device. Some of your portable electronics, like laptops and tablets, will use a lot of power, so you may not be able to fully charge these with a smaller-capacity power bank.

Size and Weight

Power banks should be portable, and your definition of this term will depend on how much weight you are willing to tolerate. You may want a device that slips into a pocket or fits easily into your purse, but this could limit your capacity. Look carefully at the dimensions and weight of any charger you like to see if it will be something you can comfortably carry in a way that meets your needs.

Number of Ports

Most of us have more than one portable device these days, including phones, tablets, wireless headphones, speakers, and much more. If you want to be able to charge more than one thing at a time, be sure to look for a power bank with multiple ports. The smaller the power bank, the fewer ports it is likely to have.


Not all power banks can charge all portable devices. Some, like laptops and certain models of Android phones, require a higher voltage than many power banks can deliver. You should always check the manufacturer’s specifications before buying a power bank to ensure that you will be able to charge all your current devices with it.


When it comes to portable chargers, there are two speeds to consider. The first is how quickly will the power bank charge your device. Does it come with a quick-charge feature or option? And can you charge your device while also charging the power bank?

The other speed that will be important to many busy people is how long it takes to fully recharge the power bank itself. While most will charge overnight with no problems, if you need a faster turnaround, be sure to look for this detail.

Safety Features

Nearly all models available today offer some protection against short-circuiting, overloads, and too much current. In most cases, the portable power banks will turn off automatically. Some companies even offer money-back guarantees against damage to your electronics.

Best Portable Power Bank

Frequently Asked Questions 

Q: What do you mean by mAh?

A: mAh is an abbreviation for milliamp hours, which is a measure of how much charge your portable battery can hold. Manufacturers state the capacity of their power banks using this measurement, which is standard and allows you to compare one device to another. The higher the number, the more charge it can hold.

Q: How do I know if my power bank will last?
A: When it comes to these types of devices, you will get a longer life from those with higher-quality batteries with technology that optimizes their charging cycles. The higher the output of the ports, the fewer times (theoretically) you will need to charge a device, which improves your charger’s lifespan. Smaller capacity batteries need to be recharged often, which often reduces battery life, as well.

Power banks, like all types of batteries, will start to degrade over time. Usually after a few years, you may notice a drop in performance, but the charger will continue working for a long time before it finally can no longer hold a charge.

Q: Are power banks safe for my expensive devices?
A: Power banks today are the safest they have ever been. Reputable manufacturers include many safety features and fail-safes that prevent damage to your electronics, but you should always view their specifications to ensure this is the case.

Q: What kind of battery is inside my power bank?
A: Most power banks today use a lithium-ion or a lithium-polymer battery. Check with your manufacturer’s specifications to know for sure which is used.

Q: Can I travel on a plane with my portable charger?
A: Most power banks on our list are well under the allowable limit of 100-watt hours for air travel today. The largest capacity units may put you over the limit for checked baggage, but you may still be able to have it in your carry-on. Check with your airline if you have any query.

Q: How can I make my portable charger last as long as possible?
A: When charging your power bank, it is best to do so when it is fully discharged. If you do not use your portable charger often, be sure to charge it at least every few months. Storing your power bank in a cool, dry place will also extend the life of your battery. Keep your portable charger away from extreme temperatures or direct sunlight, as well.


For many, having a portable power bank is nice to have, but for those who travel a lot or work out of the office frequently, knowing you will not run out of charge on your critical devices is essential. Power banks are useful tools for ensuring you never run out of power on your phone, tablet, and other portable devices. And with the wide range of options available, there is a power bank that meets your needs and budget, for sure.

Selecting among our list of top 10 best portable power banks gives you options for capacity, versatility, portability, style, and speed. And while a larger budget will provide you with more options and features, you don’t have to spend a lot on a power bank to get reliable, safe charging capacity that will help you until you get home or back to the office.

Today’s charging technology just keeps getting better, and with batteries lasting longer than ever before, there has never been a better time to invest in a power bank for your personal or professional use. We feel confident you can find the perfect one for you among our top ten choices.
