Does anyone have any experience with this seller?
The brand?
This item?
Completely unknown to me. OP, you bought from here before??

this isn't a "generator" at all right? just a battery pack? looks like quite the sale if the original price is valid...but total unknown re quality/value.

Do you need a battery from the solar panel to charge this or can you go directly from the solar panels to this power storage generator?

*Solar Panel Not Included* So why mention it? You could charge it from a nuclear power plant, too. *not included*

Battery Cell: Samsung Li-ion 18650-2200mah ~50 of them to get 400mAh
if they were using 3350 LG it would need 32 to get 400WH

this item is sold under many names
Renogy Rugged Power Pack [amazon.com]
HY-PS5B ACOPOWER 400Wh Portable Solar Generator [amazon.com]
POWEROAK 400Wh Portable Power Solar Generator
and others

This looks really interesting but I've never heard of this seller before so I can't justify the purchase.
If this was through Amazon or BuyDig or Monoprice or some other company I knew had reasonable returns I'd definitely get this.
this seller is also selling it on Amazon [amazon.com]

Don't confuse amp hours with watt hours.
400 watt hours divided by 5volts is only 80amp hours, only 4x the capacity of a 20,000 mAh power bank. At 12v, it's only 33 amp hours or slightly less than double the capacity of a typical $60 jump starter.
It seems like being marketed as a solar generator, they're charging 4x as much amp hour for amp hour as a power bank.

if you are trying to help you are not
and you are throwing numbers that are meaningless

i will show 1 mistake
in order to figure out watt hours or WH which is more meaningful then mAh
you take the BATTERY VOLTAGE of 3.7v and you Multipy by its Amps 2200mah do not use the output voltage of 5v in any part of your core formula
so its ~3.7* ~2.2 = ~8.14Wh * 50 = ~407wh

i cannot follow you after that

This is correct, i normally just count 1 cell as 8 WH... 4 volts X 2 amps.... that typically work, this has a built in inverter and solar charger controller... so not bad.

I've had the yeti 1250 for about 10 years, and it's great to charge my phone and for an emergency purpose. However, most phones are power hungry when charging via the usb on my yeti, and it trips something in it and changes the status led from green to red and stops charging. Looks like they don't limit the power but have circuit breakers built in. I kind of wish they limited the power so I could at least charge my phone with it.
