Plugable Power 3-Port USB Smart Charger Cup for Cars

USB has become more than a way of connecting devices to a computer with plug and play ease and high performance. It has also become the method of choice to power and charge a range of battery-powered devices from headsets to controllers to phones and tablets. Unfortunately, USB charging is not well standardized and in the car on the go most people need to have an expensive dedicated car charger for each of their mobile devices. Often only one device can be charged at a time due to not enough 12V accessory sockets and keeping separate chargers for each device can clutter up the car interior. The USB-C3C can help solve these frustrations by offering three dedicated USB smart charging ports in one compact drinking cup sized package to tuck away cleanly and securely in the car cup holder.


  • Charge up to 3 devices simultaneously at up to 2.4A per port
  • Up to 36 watts, 7.2A to share across all 3 ports
  • Supports tablets, cell phones, MP3 players, and other USB peripherals
  • Three dedicated smart charging ports that automatically select the best charging mechanism for the device
  • 5FT power cable, fits standard 12V automotive accessory socket (cigarette lighter)
  • Storage compartment for tucking in loose charging cables and small items (small phones may also fit, such as the iPhone 4 for example)

USB Charging

Battery charging over USB has become a standard practice but the actual charging behavior of different devices is often unpredictable and sometimes disappointing. The devices themselves decide how much current to draw and manufacturers haven’t settled on a single standard. We constantly test our products with as many different devices as possible and publish the results so it’s easy to determine the charging behavior to expect from your device on each of our USB products. These are the results for the devices we’ve tested on this charger so far.

For hubs, "Hosted" means the hub is attached to a host computer that is powered on. "Unhosted" means just the opposite, that the hub isn't attached to a host computer, or that the host computer is turned off. This doesn't apply to stand-alone chargers that only plug in to a wall outlet.

The "Estimated Charging Time" column is the minimum amount of time that the device would take to charge if it was fully drained. This is just an estimate! We provided this to give a general idea of the expected charge time. If this column is blank for a device, that means that the device indicated that it wasn't charging. In this case, even if the device is drawing power, it will likely either "tread water" keeping the battery at a constant level, or slowly lose ground.


Can the USB-C3C charge iPods/iPads and other smartphones?
The USB-C3C charging station has an intelligent charging chipset that supports the Apple 1A, Apple 2A, Apple 2.4A, Samsung 2.4A, Android, and USB IF BC 1.2 charging signals. With such a wide array of charging signals supported, most Apple, Android, and Windows phones and tablets are supported. For some devices like the iPhone 6 and 6 Plus, they will charge faster connected to the C3C than with their bundled power adapters.

What does the blue light mean?
The blue light indicates that the charger is receiving power. When first connected to a 12V automotive accessory socket, the blue light should turn on in a few seconds, if it’s not or the light is blinking, there’s something wrong — contact us at for assistance.

Is there a way to turn off the blue LED on the charger?
No, the LED indicates the charger is receiving power and is on and ready to charge devices.
