+1 to what Stevan said. Sailboat Owners had some testing results published recently and charging an iPad (of all things) came about 20-25% less over a DC charger (compared to the inverter/AC charger combo). These inverters are not as efficient as we would like them to be.
A note: check the DC (USB) charger before buying/installing; they come in a variety of specs (1.5 A/2.0 A/2.5 A). For fully charging higher end devices (e.g. tablets) you want to have 2.4 A – 2.5 A USB charger.

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. Steve Suhana, C&C 32 Toronto
