TESSAN is out here offering a 20,000 mAh power bank with 30 watt USB C charging and built in USB C and Lightning cables for less than that. You get a Lightning cable and a USB C cable permanently attached to the bank itself, plus a separate USB C port and USB A port on the side. The 30 watt output means you can actually fast charge modern phones or keep a thin laptop limping along during a long meeting. TESSAN says it will push an iPhone 15 Pro to 53 percent in half an hour, which tracks with standard USB C PD speeds. If the cables fray in a year, you discard it as e-waste and buy another one for less than the cost of replacing a single USB C cable from Apple.
