Superbank is a compact, 130W 20,000mAh power bank optimized for travel and sustainability. The team reengineered the circuit board and battery layout, arranging components from high to low to maximize space efficiency. The aluminum body enhances heat dissipation and charging. With only four screws, it's eco-friendly, easy to assemble, and repairable. The hook design protects the charging port, while the universal design reduces material waste and costs.
