Why it's worth it
The Blade is a flat 20,000mAh slab that pushes 100W over USB-C and still keeps two USB-A ports for older cables. It's under an inch thick, so it lies against your laptop instead of bulging out the side of your bag.
Flat is the entire argument here. At 0.78 inches thick, it slides into the same sleeve pocket as a 13-inch laptop and disappears. Most 100W banks are bricks that force you to reorganize your bag around them. If you pack light and hate lumps, this shape is the one that keeps you honest about what you carry.
100W covers a real working laptop, not just a phone. Baseus says it takes a MacBook Pro to 50 percent in half an hour, and it should manage three or four full charges of a large phone. That's a coast-to-coast flight with the laptop open, which is exactly the scenario cheaper banks fail at.
