The short answer on power station vs gas generator for air conditioner use: a gas generator runs an air conditioner through an outage, while a power station covers small loads and stays silent indoors. We compared a compact power station and inverter generators on what each listing states: watts, runtime, noise and weight. The generators carry the cooling load; the station covers phones, laptops and lights.

Running watts and the cooling load
The gap in watts is the whole comparison. The PowerSmart lists 3800 starting watts and 3300 running watts on gasoline, and 3500 starting watts with 3100 running watts on propane. The POXURIO lists 2450 starting watts and names RV air conditioners among the loads it runs, but it states no running-watts figure, so the continuous load it can carry stays unclear. The MARBERO lists 300W AC output with a 350W peak, and a line in the listing limits appliance wattage under 100W, so it suits phones, laptops, lights and small fans, not an air conditioner.
Runtime and fuel
Runtime separates the two generator designs from the station. The PowerSmart runs up to 8 hours on a 1.3-gallon gasoline tank and up to 24 hours with a standard 20-lb propane tank, so propane stretches the run without refueling. The POXURIO carries a 6L tank, stated as 1.6 gallons in the title, and the listing gives two runtime figures: up to 10 hours at 25% load in the bullets and 8.3 hours of use in the title. The MARBERO holds 296Wh and lists per-device runtimes: a mobile phone 25 times, a laptop 4 times, a CPAP machine about 9 hours, an LED light more than 90 hours and a mini refrigerator about 10 hours. It recharges in 7-8 hours from an AC wall socket, from a solar panel at DC 16.6 to 25V and 1.5A maximum, with the panel sold separately, or from a car lighter outlet.
Noise and weight
The station is the quiet choice and the easiest carry. The MARBERO states noise-free running at 5.7 pounds, with a compact handle. The PowerSmart states noise as low as 59 dBA at 23 feet and weighs 50.7 pounds. The POXURIO states 59 decibels with no distance given and weighs 43.0 pounds. The two noise figures for the generators share the same number, but the listings measure them differently, so treat them as maker figures rather than a head-to-head result.
What the listings leave unclear
Some lines in these listings deserve a closer look. The MARBERO limits appliance wattage under 100W in a bullet while the same listing states 300W AC output with a 350W peak, so the safe reading is the lower figure. The POXURIO title states 8.3 hours of use while the bullets state up to 10 hours at 25% load, and running watts are not stated at all. The PowerSmart spec table lists Size as 1ps Pack of 24, which describes no part of a generator with a 1.3-gallon tank. Neither the MARBERO nor the POXURIO names a UL listing; the PowerSmart names UL 2201.

Every total is translated into a figure between 9.2 and 9.8 with a linear formula; ranking by points and ranking by score always agree.
Power station vs gas generator for air conditioner: which should you choose?
Pick a gas generator if the air conditioner must run through an outage. The PowerSmart carries the highest stated watts here, with 3800 starting watts and 3300 running watts on gasoline, plus propane as another fuel. The POXURIO suits a smaller cooling load with 2450 starting watts, but its running watts are not stated. Pick the power station if the load is small and the space is indoors: the MARBERO runs phones, laptops, lights and a CPAP machine in silence at 5.7 pounds, and it cannot run an air conditioner.
