A graphene-enhanced mobile pack was reportedly developed by Chinese mobile network carrier China Telecom, and unveiled in a recent trade show in Guangzhou. The mobile power pack is said to allow for a 10 minute recharge time of mobile devices with a 6000mAh battery. The power pack's price and release date have not yet been announced.
China Telecom's graphene-based pack is said to have relatively lower energy density compared to existing regular power packs. It is also enclosed in aluminum panels to protect the graphene materials. It comes with a USB-A port and supports QC3.0 output (5V3A/9V2A/12V1.5A). The device also has a MircoUSB port offering power up to 5V2.4A. On the bottom of the device sits a DC power jack that supports high-power recharge with 9V-40V and 120W (12V10A).In July 2016, Dongxu Optoelectronic Technology unveiled a graphene battery in Beijing, China.
