QBrand Laptop Power Bank 20000mAh 118W - Portable Laptop Charger

In this review the QBrand Laptop Power Bank 20000mAh stands out as a high-capacity, fast-charging option for travelers and professionals who need reliable power for laptops and mobile devices. The single biggest reason to buy is its combination of a true 100W USB-C Power Delivery output and a 20,000mAh cell capacity, which lets users top up a 15in MacBook Pro and still carry enough reserve for phones and tablets. It sits between compact phone power banks and bulky UPS-style units, offering a practical balance of speed, portability, and multi-device support.

Key Features

• 100W Power Delivery: The USB-C port delivers PD 100W (listed up to 118W combined) to charge a 15in laptop quickly, able to fill a 15in MacBook Pro from 0% to 100% in roughly 1.5 hours using the right cable and charger.
• Large 20,000mAh capacity: The high-capacity cell provides multiple full charges for phones and tablets, with roughly five charges for an iPhone 12 and over two full charges for an iPad mini 5.
• Two simultaneous outputs: One USB-C PD port and one USB-A QC 18W port let you charge a laptop and a phone at the same time with a maximum total output of 118W.
• Bi-directional USB-C: The USB-C port acts as both input and output, so the power bank can be recharged fast with a 65W wall charger and included 100W USB-C cable.
• Digital power screen: A smart digital display shows remaining battery percentage so users know when to recharge before a trip.
• Safety certifications: UL, CE, RoHS and FCC certifications indicate built-in protections against overcharge, overheating and short-circuiting.

Who It's For

This power bank is aimed at business travelers, remote workers, and students who carry a USB-C laptop and want a portable solution to extend work time away from outlets. It is particularly useful on flights, in meetings, or at remote locations where access to mains power is limited.

It is less well suited for strictly lightweight commuters who prioritize smallest possible size, or users who need many simultaneous USB-A ports. Buyers seeking fully silent, long-term continuous power for stationary desktop use should consider larger AC-capable battery systems instead.

Pros & Cons

Pros

• High-speed 100W PD output that can rapidly charge compatible 15in laptops.

• Two output ports let you charge a laptop and phone together, improving convenience on the road.
• Digital battery readout and safety certifications increase usability and confidence.

Cons

• Customer feedback includes mixed reports on charging consistency, so individual experience may vary.
• Only one USB-C output limits simultaneous high-wattage charging of two laptops.

Our Verdict
