Can you please back this up with any sort of facts.
Yes, the original PPS were designed for camping and had very limited charge cycles. This is no longer the case.
Ecoflow even advertise them as solutions for loadshedding:

There are 10's of thousands of satisfied users with the load shedding scenario.
Most that aren't happy didn't read the product spec and expect them to power their house or act as a UPS (Source: TAL Reviews). This also applies to the trolleys.
OP also lives in an apartment so I'd imagine a PPS will fit in a lot better than a trolley.
The only advantage I see of a trolley is repairability but with 2500 cycles on the battery I don't think its a big deal anymore.
