Choosing a 12V double acting hydraulic power unit for a dump trailer or lift table starts with two seemingly similar options. Both units run on 12V DC and operate as double acting pumps, but the specification sheet quickly shows where they diverge: reservoir size, weight, and listed price. If you are replacing a worn-out power unit or building a new hydraulic setup, the choice is not about raw output, because both deliver the same motor and flow ratings. The real decision is about how much oil you want to keep in the tank, how much weight you are comfortable mounting, and what you want to spend.
Quick verdict
If you need a larger onboard oil supply and steel housing, the Uimoso is the stronger pick. If you prefer a more compact package, the VEVOR is the one to get.
Comparison table
| Spec | Uimoso 6 Quart | VEVOR 4 Quart |
|---|---|---|
| Listed price | $198.99 | $188.99 |
| Reservoir | 6 quart | 4 quart |
| Flow rate | 0.91 GPM | 0.91 GPM (3.4 L/min) |
| Motor power | 1.6 kW | 1.6 kW |
| Net weight | 28.5 lb / 12.95 kg | 24.7 lb / 11.2 kg |
A quick look at the table shows that the split is mainly about reservoir capacity and weight.
Where each product wins
The Uimoso wins on reservoir capacity and steel material. The VEVOR is the lower-priced unit at $188.99, while the Uimoso lists for $198.99.
Uimoso Hydraulic Power Unit
The Uimoso hydraulic power unit is the choice when you want more oil on hand. Its larger reservoir gives you a bigger buffer for double acting cylinders, which is useful on lift tables or dump trailer setups that cycle frequently. The listed steel material points to a solid, rigid housing, and the overall build is meant for demanding lifting tasks. In practice, extra oil volume means the pump does not have to work as hard to maintain pressure during repeated lifting, which is a real advantage for jobs that involve moving a heavy load multiple times in a session. The trade-off is obvious: you are handling a heavier component during installation, and if you are trying to keep the trailer weight down, that difference matters. Still, for applications that need extended oil reserve without frequent topping off, the Uimoso's larger tank is the reason to pick it.
VEVOR Hydraulic Power Unit
The VEVOR hydraulic power unit is the lighter option, which makes mounting easier, especially if you are working alone or in a tight area. Its smaller reservoir still handles intermittent S3 cycle operation, and the description notes it is not meant for continuous long-term use. That limitation is fine for a dump trailer that lifts, holds, and lowers, but less ideal if you are running a production line with non-stop duty. Because the VEVOR shares the same 1.6 kW motor and 0.91 GPM flow as the Uimoso, you are not giving up output when you go with the smaller tank. If your priority is a compact, lower-weight unit that you can bolt in without wrestling a heavy component, the VEVOR is the more convenient pick.
Final choice by use case
If you plan to run frequent lift-and-lower cycles on a dump trailer and want a unit that is easier to bolt in place, the VEVOR is a smart fit. If your setup has a bigger cylinder or you want more oil on tap, the Uimoso's larger reservoir and steel housing are worth the extra pounds. Both are double acting 12V units, so either will handle the same basic lifting duties; the final pick comes down to reservoir preference and physical handling.
