I'd recommend a 12v fridge/freezer instead. There's tons of reliable, super power efficient, low cost options out there now(mostly the same just rebranded). A 20-36 quart size is perfect and can be run off the cars 12v outlet or a Goal Zero, Jackery, Ecoflow type power station. I've been using an Alpicool CF35 for 2 years now a few days a week and for a year prior to that used the smaller C20. In my Gen 3 Prius I had it run off the 12v battery but in my Gen 4 Prius Prime I have it running off a Jackery Explorer 500(you can use smaller) that I leave plugged into the cars 12v outlet so that it's constantly topping off the power station and allows pass-through charging of anything connected to it. You'll get tired of draining melted ice/water and crap getting soggy. You can get just about any decent 12v fridge(don't need a Dometic or ARB) for about $250 and a smaller power station for about $230.

Would this be enough?

Something like that? I always just suggest not spending anything to do with charging limes, thats just a cost youll need to recoup before making profit.
That model is likely overkill to charge ~50%...sounds like you really only need a small top up (20% or so) to get you back home under power:
This one would almost certainly get you what you need to get home under power:
I suspect this would get you 15-20% increase in charge over what you pulled in from your commute with.
if you wanted to go with one of the hefty jackery ones, this one would likely get you 60% from 0 or more charge into the battery of the rev (67k mah):
no need to spend 425 USD.
PS: this one is crazy cheap and would likely charge you to at least 60% from 0 (great reviews to boot) - at 64.8k mah slightly less mah than Jackery hefty one, but nearly identical spec wise, and much cheaper:
I may even give that a go for the price!
Source: I own this one and it charges my rev from 50% to about 95% (42k mah, while the two bigger guys above are around ~65k mah):
I can't recommend the one that I own...had some issues with it.
Does the mount come with the standard cigarette lighter plug in?
If so and youβre looking to go portable this has worked well for me.

Depends on the voltage of what you're using. Could probably charge your phone at least a dozen times. If you plug in a larger fan, it would probably last you from Friday - Saturday with phone charging as well.
Edit: my buddy uses this while camping and it lasts him a few days running a USB fan and charging electronics. https://www.amazon.com/dp/B07D29QNMJ/ref=cm_sw_r_apan_glt_i_ZDQ28XPRFNPG0F73BQYN
From a cost and efficiency standpoint, you're better off just getting these lights. Not only is it cheaper than buying a panel and an inverter. But trying to convert to AC is going to have some decent inverter loss. These lights are all DC, so no inverter loss and it's all self contained, just string them up and you're good to go.
The alternative is to get a small solar generator kit like this. It's not waterproof or anything so it would have to be something you bring out and plug in when you want the lights.
The even more expensive alternative is to get a 200-300 watt panel, an MPPT controller with an inverter, and a battery. But you're now looking at a several hundred dollar setup.
The amp uses 47 watts. I don't think it changes much no matter which output setting you use, 0.5, 25 or 50 watt.
A 20Ah (240 Wh) portable battery should run it for about 2.5 to 3.5 hours. Mathmatically it's over 5 hours but that would be depleting the battery to 0 which the battery pack won't do.
The Jackery 240 should do it.
Jackery 240 battery is 41% off - $176 USD + tax.

I suggest that you slightly change your approach and go with an AC plug-capable battery like Jackery.

Then use a dummy battery that plugs into the AC (wall power) like battery.
These portable powet packs are amazing for many other purposes (just last week, I was able to power a Zoom video conference with a laptop, full hdmi monitor, mic and gh5 outside).
I now have multiple Jackery batteries of different capacities and weights; and a solar panel for other emergencies.
