Great little unit, I bought one last year for about $125, without the charger. Great for charging phones, Bluetooth devices, tablets, etc..

By cycled it, do you mean turning it off?
Yes cycled it on and off when it got too hot. You can manage and monitor it via the app. It oddly connects better than my Solix C800.

Quote from mysterieagain :
I bought this exact power station for my trip from Texas to California. LiFePO4 is safer but it's still somewhat dangerous. I didn't place it properly during the first day of my trip and it fell over covering one side with the vents so got hot pretty quickly. I was monitoring the battery and when it got too hot I shut it off in cycles. It runs cooler if you are not using the bypass (used a cig lighter adapter). It can run well by itself for a few hours with a Bodega 53qt dual zone cooler.
is there a sodium ion comparable power station this size maybe?. seems safer and those should be increasingly available. I really like that sodium ion is not as throttled by the few places that raw materials have to be dug out for lithium ion batteries.

Good price, I have two.

Two weaknesses I want to point about this unit

1, when WiFi is out, you can't connect it with Bluetooth automatically

2, it does not have any programming capabilities

Its strange, my 5 year old 160wh jackery has one, i almost bought this to have another small one but saw no ac
Anker sells a different model with AC outlets on their website. Amazon has it on sale a bit but nothing close to Costco price for this kind of product.

I use this to charge up all my devices overnight. I charge this with solar panels during the day.

I don't think Sodium Ion batteries are big on the market yet. I could be wrong but I see only a few items right now (what I see is still kinda shady). I think Solid State batteries are the next new thing for right now but even they are better not quite 100%. I'm not knocking this unit, I like mine just keep in mind it's a lithium battery at the end of the day.

Around how long can this power an average home boiler heater (gas but electric pump)?

According to Google, the average electric pump for a gas boiler uses about 100-200W. At this rate, the battery would be drained after 1.5-3 hours.
This doesn't have any AC output ports so it most likely wouldn't work anyways

No AC? So it just a fancy power bank?

Wouldnt getting several 20,000 mAh power banks that go as low as $10 sometimes a better choice?

Good price. The Ecoflow Trail 300 looks like the equivalent and it's going for $140. Looks like it'll power my Starlink Mini for maybe 12 hours.

No ac outlet is weird, that comes in handy
No, it's designed for DC use only. That's why it's so small. Anker has a similar unit that has AC, but it's not as compact.

Oh yeah! I couldn't remember why I avoided this model when I was looking for a medium sized device previously. THAT was the reasoning.
They do have another unit that includes an AC outlet with 300 watt max capability, but it's nowhere near as compact.
