MediaTek has announced their latest entry in the quick-charging battery technology field, Pump Express 3.0, to compete with offerings like Qualcomm's Quick Charge 3.0. MediaTek claims their latest version of Pump Express can charge a smartphone battery from zero to 70 percent in a mere 20 minutes, although they do not indicate what size battery they are basing that measurement on. MediaTek also says a five minute charge will supply enough juice for four hours of talk time.
MediaTek's solution is unique in that it bypasses the charging circuitry inside smartphones to directly charge the battery. By using this method, it appears MediaTek was able to get around issues with power delivery using Type-C USB connections by not adjusting the Vbus. Although users may be concerned with a technology that bypasses safety features in a phone's circuitry, MediaTek says Pump Express 3.0 is bi-directional and has over 20 safety and device protection systems built-in. Notably, these safeguards are designed to prevent overheating and overcharging issues.
Jeffrey Ju, Executive Vice President and co-Chief Operating Officer for MediaTek says,
“The engineering challenge in the smartphone world today is satisfying consumer demand for powerful, rich multimedia features without needing to plug in their phones all day long. Our technology lets consumers power up quickly to stay connected, on the go and using their favorite applications whether for work or play instead of tethered to an outlet.”
The first devices to get Pump Express 3.0 will be those equipped with the Helio series P20 chips that are expected to ship by the end of 2016.
