Baseus Blade Laptop 100W vs Aukey Spark Mini: Same Capacity, Very Different Power
Two 20,000mAh power banks, priced within a dollar of each other ($33 vs $33.99), might look interchangeable at a glance — but a 100W-vs-20W gap in output power makes them suited to genuinely different jobs.
Baseus built the Blade specifically to be slim enough to slide into a laptop bag while still delivering 100W — enough to meaningfully charge a USB-C laptop, not just a phone.
Global reference price
Aukey's Spark Mini keeps things basic: 20,000mAh of capacity with a standard 20W PD output, aimed squarely at phone and tablet charging.

Key Differences
This is the rare case where identical capacity and near-identical price hide a fundamental difference in capability. 20W is enough for fast phone charging but does essentially nothing useful for a laptop; 100W crosses into genuinely practical laptop-charging territory. Anyone comparing these two purely on capacity-per-dollar would miss the single fact that matters most: only one of them can actually recharge a laptop at a usable speed.
