EDITOR'S NOTE: March 2023

Omnicharge's new 38,400mAh Omni 40+ is coming soon, offering three USB-C and two USB-A ports for a combined output of 150w. A launch offer is also available if you sign up on their website.

To clarify the TSA rules, they state that battery packs must be stored in your carry-on baggage only. You can carry two extra power packs up to 160Wh each with airline approval.

Having the best laptop power bank or battery charger in your portable arsenal is a good idea, especially if you do a lot of traveling or like to squeeze in some more work while commuting to and from the office. These days, you shouldn’t go anywhere without one. 

While the battery lives of many of the best laptops are now longer than ever, longevity still depends on how demanding the tasks they handle are. And, it’s not like you can just find an outlet anywhere – even big-name coffee shops like Starbucks are making outlets inaccessible to patrons.

The good news is that many laptops today are designed with USB-C charging available. So, just like regular power banks for smartphone-dependent teenagers, laptop battery chargers have fast become an integral part of any professional’s setup, specifically those who work remotely or enjoy working at a cafe. And, just like regular power banks, they come with various port options – some even come with an AC outlet for those whose laptops do not offer USB-C charging. 

Getting a portable laptop battery charger or power bank isn’t as straightforward. You should check to see what laptops the chargers support, as some laptops still come with proprietary chargers, and ensure that it has the right connector to plug your laptop in. You'll need to consider how much power they supply, as particularly power-hungry laptops, such as gaming laptops, may not work with them. Finally, check how large their internal batteries are, as this will dictate how many times the charger can charge a laptop, and their overall size, as you don't want to lug around a large and heavy charger.

As complicated as that sounds, you will find that the ideal laptop charger or power bank for you is worth all the effort. Besides, we’ve gathered the best portable laptop chargers 2023 offers to save you time and hassle. Take a look at our top picks below.

Dell sells the Power Companion with various battery capacities. It is more compact than the RAVPower models, and the unit looks like a Dell power brick that charges your laptop. When you're at your desk, you can daisy-chain to recharge the Power Companion and your Dell laptop by connecting your Dell charging brick to the Power Companion and then connecting it to your notebook.

Dell's Power Companion is a far-sleeker battery pack if your office relies on Dell Inspiron, Latitude, XPS, or Venue laptops and tablets. It has extra USB ports should you need them.
