Deal Details
Came across this and it actually looks like a pretty decent little power station if you stack the code. It drops from $169.99 down to around ~$105, which feels pretty low for a 256Wh unit with LiFePO4.

It's rated at 400W (800W surge), so more for smaller stuff like laptops, routers, maybe a mini fridge or CPAP. The battery is LFP with 4000+ cycles which is nice since most cheaper ones in this range still use regular Li-ion. Charging speed also looks fast for the size, they claim about 0–80% in ~1.5 hours if you use both inputs.

One thing that stood out is it also has a built-in jump starter (400A peak), which is kinda random but actually useful if you keep it in the car. Otherwise it's the usual ports setup with AC, USB-C, USB-A, car port, etc. Supports solar too if you're into that.

Weight is around 6.3 lbs so pretty easy to throw in a bag or keep in the trunk. Says it's quieter than most, not sure how true that is but these small units are usually fine anyway.

At around ~$100 after code, feels like a solid option if you just want something simple for backup or travel without spending $300+.

256/20=12.8-the power consumption on the unit itself.

$105 is a pretty good deal.
A lot of the power station in this size is 300w/~280wh.
This one is 400w so that extra 100w will come in handy at times.
I have a few power stations this size at 300w and at times, I needed just a little more power.
600w would be a great but we're talking about $100 here.
That jump starter is a huge bonus.
This is something you can leave the in the car permanently.

Let's add in the loss of inverter efficiency.
Most the the smaller power station efficiency is 80-85%.
256*80 = 218/20. Say around 10 hrs give or take.

I'd highly recommend spending $200 dollars more and get something that has 500% more capacity & 4 times the inverter output at 1488Wh & 1500 watts. Like the OUPES Exodus 1500 on sale for $305. It also comes with a 6-year warranty. On top of all that, it's also 33% cheaper per Wh at 20 cents vs 31 cents for this unit. In real-world usage, It would run your fan continuously for over 63 hours. This figure is calculated at 85% efficiency or 1190 usable Wh out of 1488Wh total. In layman's terms, 63 hours is a very realistic and uninflated calculation.

You probably don't want to leave this in your car 24/7 if you live somewhere that has long cold winters. LFP is best stored above freezing temps, so 32F or above, but its also recommended to store them even warmer than that if you plan on storing them long term. Anything more than 3 months would be considered long term.

Please avoid this brand. I have one and it lasted about 3 months. They will not respond to any emails regarding a warranty claim and nobody picks up the phone, voicemail is full. So the 5 year warranty is useless.
