Kuulaa Ultra-Thin 5000mAh Magnetic Power Bank, 20W Fast Charging Mirror Design Compatible for iPhone17/16/15/14/13，Samsung/Android

The Kuulaa 5000mAh portable magnetic charger is one of the smallest, lightest, and thinnest power banks on the market, with a thickness of only 0.272 inches and a weight of 0.243 pounds. It is extremely compact and equipped with high-speed charging technology. It is compatible with iPhones and Android devices with magnetic charging functionality. Wireless charging is simple and convenient; just attach this magnetic portable charger to the back of your phone. It supports wireless charging for devices at 7.5W/15W, and the maximum wired charging power can reach 20W (50% charge in 30 minutes). It can charge two devices simultaneously. It can easily fit into any pocket or bag, making it an ideal charger for use on the sofa, during outdoor activities, on planes, or anywhere you need to charge your phone. Note: During the charging or discharging process, the magnetic power bank will heat up due to energy loss. This is a normal phenomenon and no cause for concern. Important usage instructions: Normal heating during operation: The magnetic power bank may generate slight heat (35°C–42°C) when charging, which is a common heating phenomenon in small lithium-ion devices. It has a built-in overheating protection function. When the temperature exceeds 45°C, charging will automatically pause to ensure compliance with the IEC 62368-1 safety standard ². Optimize magnetic alignment: For stronger adhesion (recommended pull force is 12N⁴), use it with a magnetic phone case (for example, models compatible with Apple MagSafe). Directly attaching it to a non-magnetic surface may reduce grip stability by 50%¹ and may affect charging efficiency.
