One hundred amp hour lithium batteries were three forty nine from the off grid store in Milton. Not bad considering.

Has anybody seen this thing? Battery / inverter/ charger all in a box , one stop job . Charges in an hour and if the stats are to be believed runs everything I need to do without being an electrician
And it can go anywhere, .

@Scuba Steve has one (or at least one similar).
Those things are nice, and they're absolutely convenient, but they're also insanely overpriced for their capacity in many cases.
2048wh at 120v means that if you're running a ~1500w appliance (ie coffee maker) you could run it for about 1.3 hours hours before the battery is dead. Obviously you're not going to run a coffee maker for 1.3 hours straight, but you get the idea - say 15 minutes for a cycle, so you'd get 5 pots of coffee before it's dead, assuming no other loads at all.
If you're using only 100w, you're going to get 20ish hours. The math is pretty simple in the end.
But, In checking, those units are $2000.
Compare that to a 100ah Lifepo4 battery (which is probably somewhere around the equivalent capacity of what's in there) for $300ish now, and an Amazon pure sine inverter with some USB plugs built in to it (I paid something like $250 for mine), and you've got somewhere in the vicinity of the same capacity for 1/4 the money. Yeah, you'll need a charger, but I picked up a 100a Lifepo4 charger on Aliexpress for $80, and there are lower amp chargers for Lifepo4 available for <$50 if you're not in a rush. In the end is it all as pretty as that Ecoflow? Nope. But at 1/4 the cost, you could put it all into a carry tote from Princess Auto or something and make it respectable, and you're still at way less than half the cost.
Here's the 280ah (for comparison) Lifepo4 that I built and currently have in our camper. At the time this cost me around $1100 for the parts (4 cells, the BMS, wire etc) and I'm sure I could build it now for even less since Lifepo4 is coming down in price every day, but it goes to show you what you can get in capacity if you don't need pretty, and you're handy. I built it in a Princess Auto tote and just have connectors on both ends of the box, one smaller set for the connection to the trailer house loads, and bigger beefier connections on the other end for the bulk of the heavy inverter load and fast charging - 150-200a in some cases.
This is perhaps far more DIY than many would like or feel comfortable doing, but here's a prefab 100ah for $299, plus your inverter, a few wires to connect between the two (one wrench needed), and bobs your unclle, $1400 left over in your wallet.
