EF ECOFLOW Rapid Pro X EF-HB-140-X Power Bank, 27,650mAh, 300W

For a workday split between meetings, travel, and time away from an outlet, the EF ECOFLOW Rapid Pro X EF-HB-140-X power bank keeps charging options close at hand. Its 27,650mAh capacity and 300W total output support charging multiple devices from one portable unit.

The built-in retractable USB-C cable measures 2 ft, so there’s a charging cable ready when you need one. A digital display shows real-time charging data, making it easier to keep track of the power bank as you use it.

With USB-C charging, app controls, and a flashlight, the Rapid Pro X brings useful features together for mobile work and everyday carry.

Tech summary

The 27,650mAh battery is designed to serve phones, laptops, and other devices while you’re away from a wall outlet. Total output reaches 300W, with one 140W USB-C port and two 65W USB-C ports. The product also supports charging four devices at once, including through its built-in cable, giving you more flexibility when several devices need power together.

Recharge options include 320W input for a full recharge in 20 minutes, 140W single-port input to reach 80% in 40 minutes, or 280W multi-port input to reach 80% in 26 minutes. These are useful when you want to replenish the power bank between trips or during a break. A 3.9-inch LCD displays real-time charging information, while app control lets you adjust themes, standby modes, and charging settings. Eco-mode and intelligent charging protection are also included.

Compatibility

The power bank is listed for laptops and smartphones, with MacBook, iPhone, and Steam Deck given as examples. Its USB-C ports and built-in USB-C cable provide charging connections for compatible devices. The 140W port and two 65W ports let you choose among multiple outputs, while the four-device charging capability suits a setup that includes both a phone and a laptop.

For travel, the battery is rated at 99.54Wh and described as TSA-approved for carry-on travel. If your usual setup relies on separate chargers and loose cables, the integrated retractable cable and multiple ports offer a more consolidated way to carry charging options.

Everyday use

At a desk, the LCD helps you see charging information while the power bank supplies connected devices. On a commute or trip, the retractable cable is ready for quick access, and the flashlight adds a practical feature when you need light in a dim space. When several devices need charging at once, the combination of built-in cable and USB-C ports lets you connect a phone, laptop, and other compatible gear together.

App controls provide another way to personalize the charging experience, including standby mode and charging settings. For frequent travel, the carry-on rating and high-capacity battery make it suited to keeping essential electronics powered between access to outlets.

Should you buy it?

You’ll appreciate it if you want one portable charger for a mix of laptop and phone charging, and value having a built-in cable, a clear LCD, and several output connections in the same device. The Rapid Pro X is especially useful for mobile work, travel, and days when more than one compatible device needs power. Its fast recharge options also give you distinct ways to replenish the battery, depending on the available input setup.
