Coowisty 10000mAh Slim Power Bank with Built-in Cables

Coowisty 10000mAh Portable Charger — a slim power bank with built-in dual cables (USB-C and Lightning), designed for quick phone top-ups and basic tablet charging. Features 5 output ports and 2 input ports with an LED display for capacity tracking. Rated for approximately 18-20W output across standard fast-charge protocols (QC/USB Power Delivery), making it suitable for iPhones and Android devices. Slim profile and integrated cables eliminate carry friction — no adapters to forget. Real-world capacity typically sits near 8000–9000mAh usable due to circuit losses, rather than the full rated 10000mAh. Slow self-recharge time (~3–4 hours via USB-C) and lack of high-wattage laptop charging limit it to phones and light tablets. Suited for everyday phone users prioritizing pocket convenience over maximum capacity or speed.
