The Velvetwire Powerslayer USB Charger is a smart device -- literally and figuratively.
The Powerslayer is literally smart, because it delivers power only when needed, so it does not overcharge your device and waste power. The LED indicator glows when charging, and then turns off when your device is fully powered -- No wasted energy here as it delivers 2 Amps of charge, for phones and tablets.
And the Powerslayer has a smart design, with an idiosyncratic rounded/angled look in a textured polycarbonate housing. It's reasonably small and light, and easy to use with a fold-out plug and the USB connector positioned slightly off-angle.
The Powerslayer USB wall charger is available for $39, in coral red, fathom black, hull off-white, and marine blue.
Velvetwire also offers a snazzy Premium USB Cable with tangle-free, braided cloth in a marine and coral color weave. It's available with an Apple Lightning or Micro-USB connector, at $19 for 1 meter and $29 for 2 meters.
There's also a Powerslayer Kit for $79, with charger, cord, and a natural leather travel case with wool felt interior.
So get smart, and you can charge away without needing to worry about leaving your device plugged in for extended periods.
PS: Next from Velvetwire is the Powerslayer Blu, due this winter, which adds Bluetooth low energy (BLE) connectivity and the option of high-power or eco-mode charging. It connects to an iOS app for monitoring, and can interact with Apple HomeKit devices.
