Choosing between hydraulic power units isn't just about picking a pump. You have to match the power source to your work environment and decide whether the cylinder needs to extend and retract under pressure or just lift in one direction. For these two options, the listed prices are only about four dollars apart, so the real differentiators are voltage, reservoir capacity, and pump action.
Quick Verdict
If you have 110V shop power and need a single-acting lift pump with a 10-quart reservoir, pick the Returned 110V Car Lift Hydraulic Power Unit. If you need 12V operation and double-acting push/pull capability in a compact hydraulic gear pump, go with the Hydraulic Power Unit 12V Double Acting Pump.

| Pump Action | Single Acting | Double Acting |
| Condition | Used | New - Open box |
| Pump Type | Hydraulic Pump | Hydraulic Gear Pump |
Where the 110V Unit Wins
- It plugs into a standard wall outlet, so it's a natural fit for a shop or garage with 110V power.
- The 10-quart reservoir is generous, and the 1.7 GPM flow rate paired with a max pressure rating of 3200 psi makes it a serious candidate for lifting heavy vehicles.
- Its single-acting design is straightforward for lift applications, and the price is the lower of the two listed options.
Where the 12V Unit Wins
- It runs on 12V, so it's much easier to use in portable, trailer, or vehicle-mounted setups where AC power isn't available.
- The double-acting pump action lets a cylinder both extend and retract under pressure, not just lift in one direction.
- The hydraulic gear pump design is described as compact and efficient for a variety of hydraulic systems, and the unit is listed as New - Open box.
Product Notes
Returned 110V Car Lift Hydraulic Power Unit 2.5 Gal /10 Qt Post Hydraulic Pump

The Returned 110V Car Lift Hydraulic Power Unit 2.5 Gal /10 Qt Post Hydraulic Pump brings a 110V motor, a 10-quart reservoir, and a 1.7 GPM flow rate to the table. Its single-acting design is straightforward for lifting applications, and the 3200 psi max pressure rating means it can handle heavy vehicles. The trade-off is the condition: the listing calls it 'Returned' and the condition is 'Used,' so you're buying a pre-owned unit rather than one in a new-open-box state. If your work is around a shop with 110V outlets and you need a direct-replacement-style lift pump, this is the one.
Hydraulic Power Unit 12V Double Acting Pump 6 Quart

The Hydraulic Power Unit 12V Double Acting Pump 6 Quart is the choice when your hydraulic system lives on a trailer, truck, or anywhere without an AC outlet. It runs on 12V electric power and uses a double-acting pump action, so it can both extend and retract a cylinder rather than just lift in one direction. The hydraulic gear pump design keeps things compact and efficient for general industrial use. The main limitation is capacity: the 6-quart reservoir is smaller than the 10-quart tank on the 110V unit, so it may not sustain long cycles at high volume. It's listed as New - Open box, which is a plus compared with the used unit.
Final Choice by Use Case
Choose the Returned 110V unit if you need a wall-powered single-acting lift pump with a 10-quart reservoir and a high-pressure rating. Choose the 12V unit if your hydraulics are mobile or battery-driven and you need double-acting push and pull. Either way, the price gap is minimal, so the infrastructure around your hydraulic system should be what makes the call.
