The Sharge Flow Powerbank ensures efficient heat dissipation by deconstructing and internalizing the classic transparent design and striped elements of the iMac G3. It uses LG batteries for a small size and high performance. Super portable design: The Sharge 10000mAh portable power bank is only a third the size of the iPhone 13 Pro and smaller than a credit card. The compact design is perfect for outdoor hikes, travel, business, and more. Unique low current mode: Unlike most portable power banks, Sharge's low current mode works not only with all phones and tablets but also with smaller devices like AirPods, Bluetooth headphones, fitness trackers, smartwatches, and more.
