2AVIX-SBWireless charging backpack

Automatic Smart Phone Charging After connecting your smartphone to the inner portable battery, please put the smartphone to the wireless charging pocket on the shoulder side. It’ll be automatically wireless-recharged. Feel free from charging cables. Charge and store your phone freely. Notes The position of the wireless charging receiver may vary depending on the phone model. Please adjust the position to allow your phone to fit into it. If the case of your phone too thick or contains metal or magnets, wireless charging may not be successful. Wireless charging speed may vary depending on the portable battery you connect to. Precautions We are not responsible for any damages to Spaker products or mobile phones caused by inadequate personal use, carelessness, or failure to observe the usage instructions and precautions listed on the detail page. Please make sure you’re aware of the precautions to use the product. Please avoid dropping the bag from a high place, throwing it on the floor, or pulling the grab with a strong force, as this can cause malfunction. Unauthorized repair or disassembly of the device may be the reason you can’t use after-sales service. Stop using the product and disconnect the portable charger before cleaning and maintenance. Do not use alcohol or other detergents. Clean the bag with a soft, dry cloth. Too high or low ambient temperature may cause product failure or fire. If the bag is suddenly placed in room temperature from a cold place, it can damage the internal circuits of the product due to moisture inside the product. Do not use any third-party cable other than our company’s cable, non-standard power supply, or charger. This may cause product failure, fire or other hazards. Q. How do I wash it? ※ Do not wash with water. See the Precautions SB01 User manual Since the wireless charging device is built into the bag, do not wash with the water. Stop using the product and disconnect the portable charger before cleaning and maintenance. Do not use alcohol or other detergents. Clean the bag with a soft, dry cloth. When drying, remove the water as much as possible after washing, and spread with using hands, and then dry it in the well-ventilated shade. Please be careful not to discolor due to friction between the product and other colored fabrics. Do not rub the bag hard on rough surfaces. Please do not brush or iron the printed and embroidery parts. Do not use it in oily places. Store in a shade away from high temperature or high humidity. Please note that the shape or material of the product may be changed when exposed to a hot fire. Please note that there may be damage to clothing (peeling, fluff, etc.) when rubbing against certain clothes (cashmere, silk, knitwear, etc.) due to the nature of the material of bag products with mesh materials on the back part.
