Description The 4000 mAh Light Up Logo Wireless Powerbank (14.8Wh) has a rechargeable lithium polymer battery that can work as both a charging pad or a regular powerbank. It supports 5W wireless charging for a number of devices. If you plan to use this device to charge a phone without wireless technology, an external Qi-standard wireless charging receiver or receiver case is required. This device will work with any smartphone or tablet that does not have wireless technology through the normal powerbank capabilities. Output: 5V/2A. The included USB to micro charging cable makes this powerbank compatible with any device with a micro port and works with most plastic phone cases or covers on. Any logo you have lasered onto the powerbank will light up when charging. (Note: This item must be lasered in order to reveal its light-up functionality.) Power banks are permitted in carry-on luggage only, and at the discretion of TSA agents. Please charge the power bank before initial use.
