As any road warrior knows, a dead laptop battery can be a productivity killer. Fortunately, the market for portable power solutions has matured, offering enterprise-grade options for keeping your devices running, even far from the nearest outlet. But with safety concerns and fluctuating airline regulations, choosing the right power bank is more critical than ever.

Capacity and Compatibility: Finding the Right Fit

When selecting a laptop power bank, capacity is king. While smaller power banks may suffice for smartphones, laptops require a substantial milliamp-hour (mAh) rating, typically between 20,000 and 27,000 mAh. However, it's crucial to understand that the listed capacity doesn't translate directly to usable charge. Voltage conversions and other factors mean you'll likely only get around 60-75% efficiency.

"A power bank with a 25,000mAh (or 92Wh) capacity will typically fill a 5,000mAh (or 72Wh) laptop battery to about 75 percent," according to Engadget's recent testing. Enterprises need to factor this inefficiency into their TCO calculations when equipping employees with these devices. Also, enterprises must consider the array of ports (USB-C, USB-A, and even AC) to ensure compatibility with their existing hardware ecosystem.

Navigating Airline Restrictions and Safety Concerns

Recent incidents involving battery fires on commercial flights have led to increased scrutiny and stricter regulations. The TSA currently limits carry-on batteries to 100Wh (around 27,500mAh for 3.6V lithium-ion batteries), and some airlines, including Emirates and Southwest, have implemented further restrictions. These policies may include limiting the number of allowed portable chargers and requiring them to be kept in clear view during use. It's imperative for IT departments to stay abreast of these evolving regulations and advise employees accordingly.

The key takeaway? Always check with your airline before flying with a power bank to avoid potential delays or confiscation. Ignoring airline rules can result in significant disruptions and potentially impact productivity, especially during critical business trips.

Top Contenders in the 2026 Market

Engadget recently put over a dozen laptop power banks through rigorous testing, evaluating factors such as charging speed, capacity utilization, portability, and design. Some of the top performers include:

  • Anker Prime Power Bank (26K, 300W): A solid all-around performer with a high capacity and wattage output. The Anker Prime delivers enterprise-grade reliability.
  • HyperJuice 245W: This brick, from Hyper, boasts a hefty 27,000mAh capacity and can output 245W of power across four USB-C ports. The built-in screen shows you power distribution as well as amount of charge remaining. It also quickly charged a Samsung Galaxy S23 Ultra in just over an hour. One downside is a lack of port variety, according to Engadget.
  • UGreen Power Bank 25,000mAh 145W: A solid mid-range option that balances performance and price. UGreen delivers strong performance for the cost.

Other notable contenders include the Zendure Supertank Pro, Mophie Powerstation Pro XL, and Lion Energy Eclipse Mag. When selecting a power bank, consider factors such as the number and type of ports, the wattage output, and the overall design and portability. Wireless charging capabilities are also becoming increasingly common, although wired connections remain more efficient.
