You don’t want to be scrambling to find an outlet when your laptop battery is low. Whether you’re on a plane, in a cab, or simply caught in a power outage, a portable power bank allows you to bring an extra charge with you wherever you go. It’s critical to find a laptop power bank with the right ports and power capacity for your needs when shopping. Because you’ll be carrying this device around with you, size and weight are important considerations. The best portable laptop battery chargers have been researched and reviewed to find the best ones for various needs.
The first thing you notice about the Omni 20+ (Check latest price on Amazon) is how unlike a typical portable charger it is. The visual features on this charger are truly eye-catching, from the unique trapezoidal corners to the super-bright OLED screen that displays (probably) way more information than you’ll ever need to know. The Omni’s versatility is another standout feature; this power bank is like a Swiss Army knife of adapters and chargers.
Two 60W USB-C ports (ideal for charging power hogs like a laptop or a Nintendo Switch), two 45W USB-C ports (for less power draw), two full-sized USB-A ports (QC 3.0 compatible), a full-on wall socket, and a DC in/out port are all located around the perimeter. This breadth of functionality is quite appealing, but Omnicharge has included two additional features. First, the ports can be used as a USB 2.0 file transfer hub, eliminating the need to carry around a bunch of USB-C dongles on top of your charger.
The ability to use the flat side of the brick as a 10W wireless charging pad is perhaps the coolest feature. The entire unit has a 70-hour capacity, and using the 45W USB-C input, it can be fully charged in as little as three hours. All of this functionality comes at a price: this charger will set you back around $200, which is more than double what you’d pay for a less powerful, similar-capacity charger. However, if you’re looking for the best, the Omni USB-C+ is a strong contender.
The ZMI PowerPack 20000 (Check latest price on Amazon) is a single-device solution for just about all of your portable charging needs, including charging a MacBook. When compared to some of the other models on this list, it doesn’t have the highest power capacity, but it makes up for it with a multi-port design and compatibility with a wide range of other devices. The ZMI PowerPack is compatible with Apple MacBook (2015 and newer), MacBook Pro (2016 and newer), and MacBook Air laptops (2018 and newer).
It can also be used to charge your iPhone, iPad, Samsung, Google, Motorola, or LG smartphone, as well as your Nintendo Switch. Two USB-A ports and one USB-C port are included in the convenient three-port design. These ports support Quick Charge 3.0 and Power Delivery 2.0, allowing you to charge your devices as quickly as possible up to 45W.
But it’s the USB Hub mode that sets this charger apart—and makes it a great choice for MacBook users. The ZMI PowerPack allows you to transfer data without extra dongles by connecting accessories (such as a mouse or external drive) to the charger and then connecting the charger to your laptop. This PowerPack is under a pound and the size of a thick smartphone, making it the ideal backup for commuters or students who need to charge their devices once or twice during the day without weighing down their backpack.
This Anker bundle is ideal for MacBook users. The PowerCore+ power bank (Check latest price on Amazon), a wall charger, and a USB-C charging cable are all included. Two standard 15W USB ports and a 45W USB-C port are included in the power bank. This faster connection, combined with the included USB-C wall charger, makes this bundle an excellent choice for USB-C laptops like the MacBook Pro or the Dell XPS 13.
TSA-approved, the Anker PowerCore+ power bank weighs about 1.5 pounds. It’s surprisingly compact, at 7.7 x 3.5 x 2.4 inches, unlike many other laptop batteries on this list, making it an easy addition to your carry-on or commuter bag. And, despite its diminutive size, it wields a significant amount of power. The PowerCore+ can fully charge a 13-inch MacBook Pro or charge a smartphone six times. That’s hours and hours of additional screen time without ever having to look for a wall outlet.

Best Versatility: MAXOAK 185Wh/50000mAh External Battery Power Bank
The MAXOAK External Battery (Check latest price on Amazon) is a powerhouse of a device. It has six charging ports, for starters. One is a 20-volt/3-amp laptop port, one is a 12-volt/2.5-amp digital camera port, two are 5-volt/2.1-amp USB ports, and two are 5 volt/1 amp USB ports. Second, it has a battery capacity of 50,000 mAh, which means you can charge your laptop and phone multiple times before needing to recharge the external battery power bank.
Our tester also liked how small it is, measuring only 8.1 x 5.3 x 1.3 inches and weighing only 2.77 pounds, making it easy to pack into your camping bag without adding too much weight. Finally, it includes 14 different types of laptop connectors, covering the majority of models but excluding Apple laptops. You’ll probably be able to plug it in if you don’t have an Apple laptop or a laptop that uses USB Type C, but check to see if your laptop is supported before buying.
