I installed and used this USB socket last year . it is barely able to keep up charging the iPad when it is at full brightness as it might be during daylight sailing. I bought a cheap 3 Amp 12V converter / USB plug to hard-wire-in near the helm station for less than $10 from China. I do have a 2.5M iPad adapter cord which might come into play but I'll see how 3A works out .

One could go with something like this: http://ca.binnacle.com/p8953/BLUE-SEA-1016-DUAL-USB-CHARGER-2-SOCKET-5V-2.1A MP/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.

We did a lot of 1500 watt units and a few 2500 and 3000 watt versions. I would suggest most boats carry two of them. 1000 watt units are cheap enough now at Worst Marine for heavy loads like shop vacs and other tools. Then get a second small inverter, say about 100-150 watts, for device charging needs. Large inverters are not efficient when powering tiny loads.

That needs like size 0 battery cables from the battery to the inverter? I just looked at the things I customarily run with my inverter. PC charger = 1.5 amps. Cell phone charger = .5 amps. Tablet charger = .3 amps. Portable AC fans (one of them is in the back room waiting to go back to the boat) = .5 amps each. The total current draw can add up pretty quickly. And as I said in an earlier post, providing 8 amps of AC would exhaust my 4 battery 460 AH house bank in less than 2 1/2 hours. My point is: figure out what you want to power with it and then chose your inverter and battery bank size accordingly.

And no - you can't use a battery charger and an inverter to make a perpetual motion machine. Prime reason for inverter purchases back in the day used to be for hair dryers and blenders. Everyone wanted battery powered air conditioning, but few boats have the room for enough batteries to support it.
