Hi, I was recently looking for the same thing. This is the set up I am ordering:
For the panels--http://www.amazon.com/gp/product/B00IK19VF6/ref=ox_sc_act_title_5?ie=UTF8&psc=1&smid=A05654602L3XUQ70M87BV

I'm pretty new to this too, this is just what I've come up with from doing research and assessing my (basic)needs. I would like to hear other opinions as well.
Looks like bullshit to me.
You can use a compressor powered, 12VDC portable refrigerator and freezer effectively on the go, but you're going to need some dedicated solar power production. Let's run through some numbers:
31 liter capacity portable fridge/freezer for $611
They have a 10.5 liter capacity version for $316 if you need to go really cheap. Reviews say this unit draws an average of about 3.75A, or 45W. For quick math: watts = volts x amps.
As a comparison, you can just how much different an actual refrigeration system is from the portable unit linked above. Looking at the pricing and weights further shows just how far off this system is from being able to actually safely refrigerate your food.
In total, This is $1100 in hardware and 127lbs of equipment to be able to properly maintain cold food storage. The thing you linked is a backpack sized beverage cooler only.
I picked: Model MB7420 motorola for an example.
power draw: 12v @ 1a. 12 watts.
12v supply is really REALLY nice for the next thing i'm going to suggest: solar and a battery.

26 bucks for a charge controller:
https://www.amazon.com/HQST-Regulator-Charge-Controller-Display/dp/B00FB3OPKM/
46$: a 20 amp hour battery will be more than enough to get your thru the night. if you're concerned about cloudly days then you can double it up.

130 bucks for a 100watt solar panel
https://www.amazon.com/Renogy-Watts-Volts-Monocrystalline-Solar/dp/B009Z6CW7O/
figure 20-30 bucks in wiring and mounts and random stuff.
total cost to power it: 200-250$.
I just set my panel on a lawn chair and point it at the sun moving it a couple times during the day.

I was planning on getting a 30 Amp like this one
The panel output more like 5.5 amps /hour per 100 watt panel that's what my HQSTs do. PWM Is fine for a small solar setup better gain would be to get a 3rd panel than the extra expense of mppt. Something with a lcd to display input and output in amps is nice like HQST 30 Amp PWM Smart Solar Charge Controller with LCD Display https://www.amazon.com/dp/B00FB3OPKM/ref=cm_sw_r_cp_apa_.XETybK31ADKN
