I'm currently using a newer model BlackBerry charger with an output of 5V 750ma. I have a USB keyboard, wireless USB mouse, and network cable attached to my Pi, but upon powering on the keyboard still lags, meaning that there's a delay when I type, and letters get repeated. I know this is caused by the power adapter not being high enough to handle the output, but is there any reason why a 750ma charger wouldn't work? I was looking at this one and was wondering if it would work better?

Any advice appreciated. Thanks.
