Quick take
Choosing a hydraulic power unit usually comes down to a trade-off between power source and reservoir capacity. Do you need a self-contained 12V DC unit that can be wired into a dump trailer or lift platform, or will a 220V vane-pump station serve a fixed small machine? The four units in this comparison-three VEVOR 12V double-acting pumps and one PreAsion 220V vane-pump station-show how price, reservoir size, and flow rate separate the options. Listed prices run from $174.29 to $606.30, but the right pick depends on your power source and duty cycle.

Product notes
VEVOR 4 Quart Hydraulic Power Unit DC 12V Double Acting Hydraulic Pump White

This 12V DC power unit is a dual-acting pump with a 1.6 kW motor and a 0.91 GPM flow rate. Continuous long-term operation is not recommended, and the working cycle is rated for 30 seconds on, so it is best for intermittent lifting cycles. That makes it a sensible match for a lift platform or mobile equipment where cycles are not nonstop. The limitation is flow: at 0.91 GPM, it moves less fluid than the 2.0 GPM dump-trailer unit in this comparison, so heavier or faster lifts may need the bigger pump.
VEVOR Double Acting Hydraulic Pump 4 Quart 12V Lifting Platform Power Unit Iron

This 4-quart, 12V double-acting gear-pump unit powers both lifting and lowering. It comes with an M18\*1.5 connector and an additional SAE6 (9/16") connector that can be swapped to match your system, which gives you flexibility at the hose connection. It also has a horizontal mount and a 1.6-3.0 kW motor-power range. One limitation: the 4-quart reservoir puts it on the smaller side of fluid capacity compared with the dump-trailer unit in this lineup, so for sustained heavy cycles you'd want the larger option.
PreAsion 220V 0.75KW Hydraulic Power Unit Hydraulic Pump 40L 7MPa Vane Pump Station

This 220V vane-pump station uses a 0.75 kW motor, a 40L reservoir, and a 7MPa rated pressure. It is designed for small machinery and spaces where a compact, movable station is easier to install. The unit includes a shock-proof pressure gauge, an oil-level indicator, and a pure copper wire motor. The main limitation is the power source: it requires 220V electric supply, so it won't run on a 12V trailer or vehicle system. For a fixed shop setup or bench machine, it answers a different need than the mobile 12V units.
Double Acting Hydraulic Pump Dump Trailer 8 Quart 12V DC Unit Pack Power Unit

This VEVOR unit is the largest 12V double-acting option in the group, with an 8-quart metal reservoir. It is listed at 2.0 GPM and a 3200 PSI max, which positions it for dump trailers and other lifting/lowering jobs where more flow and capacity matter. The motor is a 1.6 kW unit and the inlet port is SAE6 (9/16"). One limitation to keep in mind: the motor power is the same as the white VEVOR power unit, so the added capacity comes from the larger reservoir and flow rate rather than a bigger motor.
Final recommendation by use case
If you're moving a dump trailer or a mobile lift on 12V power, the dump-trailer unit is the one to choose. For a lifting platform where 12V is already wired in, the white VEVOR power unit fits the bill. When you need connector flexibility in a compact 12V system, the iron VEVOR gear-pump unit is the practical pick. And for fixed small machinery with 220V available, the PreAsion vane-pump station is the one to plan around.
