Safety: Power banks contain lithium-ion cells. Use the cables the manufacturer supplies or recommends, keep the unit away from heat, and follow the manual.
The Baseus Blade 100W 20,000mAh Power Bank is a flat 20,000mAh bank with four ports, two USB-C and two USB-A, and a 100W Power Delivery output. The listing gives a thickness of 0.78 inch, which is its main selling point for laptop bags.
This review is based on the manufacturer listing and specifications. It suits people who carry a 100W-class laptop and want a slim bank. See more options in our Laptop Power Banks category.
Our Verdict
The strongest point of the Baseus Blade 100W 20,000mAh Power Bank is its slim body: 5.27 x 5.27 x 0.78 inches at 0.99 pounds, with a 100W USB-C cable included and a 24-month warranty. A real-time power display helps you monitor devices.
The trade-off is that 100W is the ceiling, so laptops with larger chargers will charge more slowly. It suits a traveler with a laptop charger rated at or below 100W; owners of bigger laptops should look at higher-output banks.

Capacity and Output
The listing gives 20,000mAh and a 100W PD output over USB-C, with two USB-A ports for smaller devices. The manufacturer says it can charge a MacBook Pro and phones, tablets and headphones together.
The listing does not break down the output across all four ports, so check the product page if you plan to use several at once.
Charging and Setup
A 100W USB-C cable and a user manual are in the box. The listing does not state a recharge time or an input rating, so check the manual before choosing a charger.
The display shows real-time power information, which helps when several devices share the bank.
Build, Size and Portability
At 5.27 x 5.27 x 0.78 inches and 0.99 pounds, the Blade is flat and square, designed to slide next to a laptop. The thinness is the reason to choose it over a thicker bank.
Baseus describes it as TSA-approved and FAA-compliant. Airlines set limits by watt-hour rating, so check the figure on the unit and your airline policy.
Features and Compatibility
The listing describes overcharge, overheat and short-circuit protection certified by UL, IEC and other reports. These are manufacturer statements, so check the certification details on the product page.

Final Verdict
The Baseus Blade 100W 20,000mAh Power Bank pairs a 0.78 inch body with 100W output, a 100W cable and a 24-month warranty. Its compromise is the 100W ceiling and an unlisted port split. It suits laptop users who prioritize a slim bag. Check the product page for details the listing leaves out. See the Baseus Blade 100W 20,000mAh Power Bank on Amazon.
