Portable Power Station 600W $399
Anybody have any reviews or info on this power station.
Lithium Or Lead Acid battery?
Battery capacity: 409.6W doesn't make sense.

409.6Wh?
Exactly right I'd say. W is not a measure of capacity. So they likely mean WH. Especially considering they have already stated that the power is 600W (not 409.6W).
Battery capacity: 409.6W doesnt make sense.
Why not?
If you had a large tank of water and turned the tap on - the watts measurement would indicate how much water is coming out of the tank, but it doesn't tell you how big the tank is. Wh or "watt hours" is how many watts is delivered over a period of hours. 410Wh could be 410 watts for an hour, or 205 watts for 2 hours.
That still doesn't explain how it doesn't make sense to OP. The link above from noneofthismatters shows how it does make sense.
12.8V x 32Ah = 409.6Wh
It didn't make sense to OP because Watts are not a measure of battery capacity.
That's like saying, Battery weight: 35 cm. (ie, doesn't make sense).
409.6W ≠ 409.6Wh.
Watts (W) is an instantaneous measurement of power. 1 Watt = 1 Joule per second.
Battery capacities are not measured in Watts, but in Watt-hours (Wh). 1 Watt-hour = 1 Watt for 1 hour. This would mean that the battery could likely service a 1 Watt load for a duration of 1 hour before being depleted. This also means that it could likely service a load of 0.5 Watts for approximately 2 hours. But It doesn't generally work that way, however, as batteries get more or less efficient depending on the load. A 1 Watt-hour battery probably couldn't service a 1 Watt load, it'd be too much for it all at once and you would see a severely decreased efficiency and thus a duration much less than the expected 1 hour. Batteries will have a specified discharge rate that the Watt-hour rating is based on: if you load it according to this, then you'll get the advertised capacity.
@Chandler: Unnecessary reply after my latest comment ;)
@Clear: Hmmm… I must have left that comment open for too long haha!
Thank you for the refresher course in power terms. The comments were very helpful; apprecate it. Along with "Clear", we all got cleared of our doubts. :)
Just walked past this in-store and was curious if anyone has one. This might be a new product line not released before?
I really have no use case but would be cool while camping I guess..
ditto
Odds are they mean 409.6WH which is 32AH x 12.8V, that matches the usual LiFePo4 spec for AH to WH calcs.
