The three power plugs are enough to set up a small mobile office and the two USB ports make charging mobile devices easy.

However, the USB ports failed to work after a year or so

I've seen some people complain that the USB ports aren't powerful enough to charge multiple devices (mostly involving tablets), but my girlfriend and I both charge our smartphones with this every night and it works fine

I love the USB ports

My only disappointment is the USB ports, I don't believe it is a 2.1 because my tablet which came with a 2.0A charger shows an x on the battery complaining that the output is insufficient, I've even tried it with nothing plugged in but the tablet by itself

That being said, I ended up returning this because the USB ports were unable to charge my BlackBerry Bold 9930 phone even if it was the only one using the USB port.

Very handy. love the usb ports.

However, the USB ports failed to work after a year or so

There are two USB ports, but only one of them works at a time.

The two USB ports work great for not having to carry around additional power adapters

I read a few reviews saying the USB ports do not work well on this

Did not work in London or Ireland - kept blowing fuses or breakers at hotels and B&B's
