Baseus Blade 2 Review: The Laptop Power Bank That Fits in a Notebook Sleeve

The Baseus Blade 2 does something most power banks can’t: it charges a MacBook Pro at full speed while being thin enough to slip into a laptop sleeve. At $100 with 140W USB-C output, it’s one of the best values in high-wattage portable charging.

Key Specs at a Glance

• Capacity: 20,000mAh / 72Wh
• Max Output: 140W USB-C
• Ports: 2x USB-C, 1x USB-A
• Weight: 0.97 lbs
• Thickness: ~0.6 inches

Who Is It For?

Travelers and remote workers who want a laptop-capable power bank that won’t add bulk to their bag. If your priority is portability over raw capacity, the Blade 2 is the best balance of power and slimness you can buy right now.

Absurdly Thin for a Laptop Charger

At roughly 0.6 inches thick, the Blade 2 is closer to a tablet than a traditional power bank. It sits flat in a bag, slides into a laptop compartment, and doesn’t create that awkward brick-shaped bulge that heavier power banks do. Baseus clearly designed this for people who obsess over bag weight and organization.

140W Output That Actually Delivers

The USB-C port pushes a full 140W via PD 3.1, which is enough to fast-charge a MacBook Pro 14-inch, a Dell XPS 15, or a ThinkPad X1 Carbon at near-wall-charger speeds. For a $100 power bank, that’s remarkable. The LED display shows real-time wattage, remaining capacity, and estimated time — no guessing how much juice you have left.

The Trade-offs

The 72Wh capacity is the main limitation. You’ll get roughly one full charge of a MacBook Air or about 70-80% of a MacBook Pro 14-inch. That’s fine for topping off, but if you need all-day laptop power away from outlets, you’ll want something larger. Also, when using multiple ports simultaneously, total output drops significantly from the 140W peak. And the USB-A port lacks Quick Charge support, so Android phones charge at basic speeds on that port.

The Bottom Line

The Baseus Blade 2 is the best ultra-slim laptop power bank at $100. You sacrifice capacity for portability, but if you want 140W charging in a package that doesn’t weigh down your bag, nothing else comes this thin at this price.
