Around the office, we’re constantly needing to connect and charge new devices. It’s always a struggle to find a power outlet with enough open spots, and getting many larger plugs to fit. Plugable’s new surge protector helps avoid both these frustrations thanks to the 4 oversized “wall-wart” capable outlets, and the 2 USB charging ports built in eliminate the need for the charging blocks for devices that can charge from USB.
With up to 4320 joule protection, the PS12-USB2 offers better surge suppression than many other bargain surge protectors. Joules are a measure of how large a surge is, so a higher joule rating means a protector is able to suppress a larger surge — so the higher the joule rating, the better protection a suppressor offers.
USB ChargingBattery 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.
