Jumpy - the Fridgening

So I bought the HULKMAN jump starter with their Amazon promotion the other day. So far I like it well enough.
It's very durable feeling and seems to deliver on the promises so far, though I haven't tried to jump anything yet. Anyway, I wondered if the included cigarette lighter adapter could handle the startup loads of the fridge (rated at MAX 15V @ 10A) and how long it would run the fridge for.
The good news is that it does seem to handle the startup loads and will run the fridge, it doesn't even seem to heat up! The bad news is that while 20,000 Milliamp hours sounds like a lot, its only 20 ahr at 3.7V or roughly 74 watt/hr. Given that I know that the motor load is about 40 watts, I was not surprised when it didn't even make it an hour. In that time it took a reported interior temp of 45 degrees and chilled it down to 36 degrees with about 20 sodas at 45 degrees as the thermal load. (inside at around 70 degrees)
So yeah, its not going to be running the fridge for any real need, but once it was down to temp, the compressor rarely kicked on again. Had I left it plugged in (I disconnected it at 20% for battery life) I probably could have gotten it to rest for a while. Also interesting is that it recovered to 30% capacity after removing the load, but that was to be expected.
If my food was already chilled, I would bet that in reasonable summer conditions I could get an honest hour out of the battery in the event I wanted to take the fridge out of the car for some reason and not worry about it.
The AC 65 watt charger puts a LOT of juice back into the battery quickly, so that's good. The bad news is that it's not full-duplex, you can't charge and use at the same time. oh well.
For $70 I'm pretty happy with it, the jumpers and accessories feel head and shoulders above the quality of the Costco/harbor freight jump packs of the world. Let's hope they are put together better than NOCO. It's nice to have this peace of mind again. Again, assuming it will actually jump-start anything.
UPDATE: it wouldn't work anyway, because it powers off if there is no load after a minute or so. I didn't really think about that.

I gotta get one of these eventually. The Noco Boost is usually what seems to get mentioned a lot but I'm sure theyre all the same chinese unit with different stickers.

Someone else on oppo recently grabbed one of these. I'm curious to hear how they hold up, as my current unit is, uh... A bit worse for wear.
