Another case of the inverter not being required to do the task at hand.
Anytime one can bypass the requirement of having to use the inverter it will likely save both money, and battery power.
I recommend skipping the Ciggy plug whenever possible too, It is a horrible, contemptible, highly resistive electrical connection, that gets worse with age and the more current it is asked to pass. I've had one of the supposedly 'better' ciggy plug and mating receptacle buzz audibly when using a PWM dimmer on some leds, and could stop the whine/buzz simply by changing the pressure on the plug, but as soon as I let off it came back.
There are USB receptacles designed to fit the same space as a ciggy plug 12v receptacle, This one shows Amps( @5vdc) as well as voltage reaching the plug.

Shop around, that was just the first hit that looked like the product I have in mind and have employed on a friend's rig.
I've installed a few of these in a friends vw bus and they do recharge his Kid's ipads at a high rate. The voltmeter and ammeter display is kind of a novelty, and is difficult to see when there are two usb cords installed in it. These do have a very small parasitic draw when they are not charging anything, somewhere under 0.01amps. Use a switch in line, or be able to pull the fuse easily, for storage mode.
The inverter is wasteful when powering 5vDC USB ports or a 19.5vDC laptop. One can get dc to dc 'car adapters' for their specific laptop for about 25$ or less, and save 5 to 15 watts of energy over using the inverter powering the provided AC/DC power brick.
150 watt DC boost converters can be had for about 2$, if one has some DIY skills.

Inverters are a necessary evil, but in my opinion, should always be the last resort, not the go to solution for everything household on battery power.
