Classes of laser devices are not awarded solely on the power of the laser.
They are based on how much power CAN the user be exposed to. The key factor is the design of the device. For example, this blue-ray drive is a class I product http://www.amazon.com/Panasonic-UJ262-Ultrathin-Blu-ray-Recorder/dp/B00HG77LSO (you can see on the sticker if you open the image), but with a writing speed of 8x it needs to have a lot of power, as much as hundreds of milliwatts. Here's the laser taken from a slightly more powerful 12x burner https://www.youtube.com/watch?v=fJ77l23xwak&ab_channel=WorldScott
It's the DESIGN of the product that matters. Since the laser is inside of an enclosure, and the product is designed to power the laser off immediately after the tray is opened, the user is never exposed to that radiation. Skarp can possibly do the same thing, by implementing a sensor to monitor if the fabric is broken. Note that by design, the radiation remains within the fiber until contact with hair breaks the total internal reflection.
And i'm sorry, but your calculations about the battery are far off.
1.1 watt hours means that it can provide the power of 1.1 watts for one hour. Very convenient unit. How long can it provide the power of 4 watts?
1.1 / 4 = 0.275 hours = 16.5 minutes
It is in fact minutes. It is not seconds. It will in fact be shorter than than since this is in fact overdriving the battery. But more importantly, none of this is a law of physics! Sure, their choice of battery is wrong, but this can be solved by using a li-ion cell. There is no physical constant that makes this device completely impossible. They aren't claiming free energy, or claiming that they can pump more air out of water than there can physically BE air dissolved in water (aka "triton") so don't throw that card. Yes they are overoptimistic, yes they very likely won't deliver anything, and maybe they already know it and decided to keep the cash instead of refunding. But big claims require proper supporting facts and sources.
