The Roav by Anker SmartCharge Spectrum is a powerful 2-port USB car charger, but it has more than a few tricks up its sleeve. In addition to being a Quick Charge 3.0 charger and having a programmable led light ring which can be set to 16,000 different colors, the charger monitors the voltage of your vehicle battery and keeps track of where you park.
I cannot comment on the Apple version of the app, but the Android version was simple to use and provided easy access to the parking monitor, the battery health monitor, and the color picker for the LED light ring.
As a charger, the SmartCharge Spectrum is among the best, offering high-speed Quick Charge 3.0 functionality on one port (for Quick Charge compatible devices) and fast charging for other devices from the other port using its proprietary PowerIQ and VoltageBoost technologies.
The real value of the SmartCharge Spectrum, at least in my opinion, is in its extra features, especially the parking monitor and the battery health monitor. When you combine those useful functions with a quality two-port car charger all for less than $20, it's truly a great value for a powerful multifunction device.
Anker has hit another home run with this clever car charger.
