We have one inquiry yesterday about our MP-PS600 600W Portable Power Station. The question is how much in Ah will it be if discharging from car charger DC output port? What's your thought on this? Welcome to share and discuss together.

That's a good question. Why? The same reason we all came to this forum. To learn, check and share.

Same regardless of output used, 577Wh minus conversion losses.

577WH (156,000mAh) = 3.7V battery, that spec does not make sense to rate one battery cell. What is the battery pack Voltage?
Where do you get the '156,000mAh' from?
156,000mAh = 156Ah. Is that battery cell rating? I hate it when they use mAh unit to make it looks like big number for people who does not understand rating unit.

They get 156,000mAh by adding all the cells as if they were in parallel. It's a complete lie and many manufacturers do it. In reality it's probably at least a 4s pack and likely something like 6s.

I don't understand. You said this was your product. Surely you know the specifications of your own product and can answer a basic consumer enquiry about it?

If it is 577Wh system and it is 12V system then that will 48Ah.

Yeah probably a 14.8V 4s pack, so 39Ah.

What's strange too is the solar input is so restricted at 18V~24V but they also claim it has MPPT, normally those would have a much larger input range.

577Wh Battery for running 600W inverter, LOL!
DC output: DC 13.2V/10A 132W, so estimate run time is about 4 Hours or so, it may be less if it has regulated output circuit so there will be some loss there.

Ok.
What is the battery chemistry? All the website says is Lithium Ion and there must be a lot of buyers wanting to know if any are lithium-ion-polymer sourced from LG's Nanging factory before sleeping beside them or driving around as depicted in the adds.
