HDfury releases what it claims is a means to safely turn any USB port into a fast-charging port-- the USB Doctor, a tiny (weighs all of 7g) device able to speed up device charging times by up to 2 times.
According to the company it not only provides a universal connector for just about any device (including iOS/Android tablets and smartphones, joypads and other gadgets), it also turns regular USB cables into dedicated "charge-only" cables.
It supports PC USB ports, power banks, car chargers and travel chargers, and also prevents the malware and accidental data exchange risks brought about with using charging kiosks.
