Amazon 24,000 mAh 140W USB-C Power Bank with Smart Digital Display - Black

Power-hungry laptops and multi-device road warriors finally have a single power bank that can keep up. The Amazon 24,000 mAh 140W USB-C Power Bank delivers flagship-level charging speed in a portable form factor, with enough capacity to refuel a 16-inch MacBook Pro, top up a tablet, and still have plenty left for your phone and earbuds. Unlike typical power banks that cap out at 65W or 100W, this unit pushes a full 140W through its USB-C port, making it one of the few truly laptop-ready batteries in its class. A smart digital display removes the guesswork, showing exact remaining percentage, voltage, and current in real time.

Highlights

• Massive 24,000 mAh / 86.4 Wh capacity – enough to charge a MacBook Pro 16" to 50% in about 52 minutes, or fully recharge a smartphone multiple times.
• Blazing 140W USB-C Power Delivery 3.1 output – supports 28V/5A, ideal for high-performance laptops like MacBook Pro, Dell XPS, and Lenovo ThinkPad.
• Dual USB-C ports plus one USB-A port – charge up to three devices simultaneously, with smart power allocation.
• Smart digital display – see exact battery percentage, output voltage, and current at a glance, so you're never caught off guard.
• Advanced safety suite – ActiveShield 2.0 and MultiProtect monitor temperature, voltage, and current to protect both the power bank and your devices.
• Rapid recharge – with a 140W USB-C charger (not included), the power bank reaches 50% in approximately 52 minutes.

In daily use

Throw it in a backpack and forget about outlet anxiety. The matte black plastic casing resists fingerprints and slips easily into a laptop sleeve. The digital display is bright enough to read in daylight but dims automatically to save power. When you plug in a laptop, the power bank automatically negotiates the highest safe charging profile – up to 140W – so you can keep working or gaming without throttling. Simultaneously, the second USB-C port can fast-charge a phone at up to 140W (when the laptop is not drawing full power), and the USB-A port delivers up to 18W for older devices, smartwatches, or wireless earbuds. Pass-through charging is supported, so you can recharge the power bank while it charges your devices overnight.
