External battery packs get bigger, and they get smaller. The MyCharge Razor Plus is a great example – a pretty healthy 3,000 mAh battery stuffed into a thin, sleek case. But, it might be speed, not size, that really sets the Razor Plus apart.
The external battery pack has two proprietary technologies inside that make it a little faster than the competition. SmartSense can detect which device you’re charging using the Razor Plus, and will automatically step up its output to the maximum allowed safely by the device being charged. PeakPower does something similar for when you’re charging the Razor Plus itself, by identifying the power source (USB, USB DCP, or Apple 2.1A), and steps up the input power appropriately. Usually, there’s a common maximum for all devices when they’re being charged, as a safety precaution. But, all devices are different, and some can safely handle larger inputs of power than others – the Razor Plus makes charging efficient for each individual device.
The 3,000 mAh battery is a high-density lithium polymer battery, which explains why the Razor Plus is so small, despite having a sizable capacity. That battery will provide 13 extra hours of talk time, 14 hours of video playback, 59 hours of music playback, or 13.5 hours of web browsing. There’s a single USB port for charging your device, so unfortunately, you won’t be able to use it to charge multiple devices.
The MyCharge Razor Plus, which is housed in a sleek anodized aluminum case, will be available soon for about $60. You’ll be able to find it at Best Buy.
