1) Light on C300 isn’t warm anymore. Instead it’s now much colder (probably lower then 5000k), not something my eyes want look at during dark hours. Though it’s displayed as warm on the box and on every picture online. My Anker 555 and SOLIX C1000 both feature warm light. It's simply false information and marketing abuse on every Anker resource at this point. I could argue you guys can be sued for this.
2) AC inverter operation cost is too high for its size and power. I was able to measure it at around 12,5W (5% of capacity) per hour. This is just not acceptable considering that C1000 which is 3 times more powerful uses same amount wattage. This simply means any low power load (which this model is made for) isn’t going to last long. 10 hours (overnight) will use 50% of capacity just to keep inverter going which leaves only 50% (125wh) of usable capacity to power my devices. I considered connecting my Air Purifier And Humidifier overnight, but it’s impossible with this kind of efficiency. It should’ve been around at least 5W per hour for the size. Funny how both Anker 521 and 522 which feature same capacity and power provide much better running inverter efficiency.
3) I can’t buy C300X (Black Version) here on Anker. Both my Anker 555 (bought from Anker) and SOLIX C1000X (bought from local shop) come in black and I love the color. This lighter grey design isn’t something I enjoy looking at tbh. I also own several Anker chargers which are also darker color than this „new“ light grey.
4) It’s not silent compared to C1000X which is truly silent with low load overnight. This one projects low humming noise even when just AC plug is turned on which I pick up instantly.

Hi,
I'm extremely happy with this station.
It is above my expectation.

Thank you!

My relatives are pleased with this power station, it's a great leap foward over my 535, especially in terms of the recharging time, and portability.
The only point to complain is the first connection with Anker app., it was failed, and required the station to reset

I have connected my desktop computer to check how long it could power it in case of power loss. Computer did POST and started to load OS, then Anker Solix shut down AC port with warning message. Then I connected the computer to wall socket, but there is nothing when trying to switch it on - it is dead.
It is stated that: "Anker SOLIX C300 Portable Power Station supports the SurgePad™ feature for up to 600W AC output.", my system has much less power requirement then that.

Very good device
