Multivoltz located at yourmultivoltz.com, which claims to be a supercharger that can quick charge any USB device on the spot and heals the battery, is untrustworthy and appears to be a scam. The Quick Charge(QC) technology, invented by Qualcomm, which Multivoltz claims to use, is not compatible with all devices and it does not repair or heal the battery. But, Multivoltz claims it is possible.
