The big deal here is that Super mCharge leans on the charge-pump principle to juice up a smartphone, which makes for high efficiency (98 percent, compared to SuperVOOC's 97 percent) and more-restrained temperatures while charging. Meizu says the battery in question will top out at 102.2 Farenheit (39 Celsius), which, while warm, isn't much warmer than the human body.

It's also important to note that we're not working with any old 3,000mAh cell either. The battery has been engineered to stay healthy for longer (Meizu says the cell can keep an 80 percent charge after 800 discharge cycles) and take on more current than traditional batteries, allowing it to accept the full power load delivered by the big AC adapter and specialized USB cable.

As always, though, we're going to have to wait to see this kind of high-speed charging in the wild. Meizu representatives here at the show declined to comment on when, exactly, the first Super mCharge phones would hit store shelves, but CEO Jack Wong is apparently targeting a 2018 release.
