As an aside, charging tablets and phones doesn't necessarily require an inverter. One could go with something like this: http://ca.binnacle.com/p8953/BLUE-SEA-1016-DUAL-USB-CHARGER-2-SOCKET-5V-2.1AMP/product_info.html
Phones and tablets are DC, why convert and convert again? I'm looking into DC power supplies for the laptop as well. So far we haven't need AC but I do have a portable inverter on board just in case. I charge my tablet and phone off of the car stereo I installed at the nav station (it has a USB port). I'm considering that Blue Sea unit just as a nice to have but the project list is long with higher priorities.
