+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.

As an aside, charging tablets and phones doesn't necessarily
require an
inverter. One could go with something like this:

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.
