2BGZ8-EB621Magnetic Wireless Power Bank

Design in California Manufactured in China User Manual Strong Magnetic Smart ChipSafety Protection Digital Display This wireless charger is not compatible with non-MagSafe phone cases, such as Otterbox Defender cases. Do not use an adapter with an output of 5V/1A (5W) or less. Both the protective phone case and the position of your device on the wireless charger will affect the charging speed. The farther it is placed from Wireless chargers make charging more convenient than wired chargers, but confined by current wireless technology, their charging speed is slower than that of wired chargers. High temperatures will reduce charging speed and restrict power, which is something that happens to all wireless chargers. It is recommended that you charge your device in environments with temperatures below 25°C / 77°F. the center of the wireless charger, the slower the charging speed will be.
