Cordless Power Grease Gun for Makita 18V Battery - High Pressure

In this review the ZUYIYI Cordless Power Grease Gun for Makita 18V battery users is evaluated for workshop and field maintenance. The bottom line: it is a practical, high-pressure electric grease gun for technicians who already own Makita 18V batteries and need fast, reliable lubrication. The single biggest reason to buy is its combination of a 12,000 PSI maximum pressure and a 5.7 oz/min flow rate, which noticeably speeds up greasing tasks on tractors, trucks, and heavy equipment compared with manual guns.

Key Features

• Makita 18V compatibility: Works with common Makita 18V lithium-ion batteries such as BL1830 and BL1860, allowing users to power the tool from an existing battery collection.
• High pressure output: The 12,000 PSI maximum pressure delivers strong, consistent force for reaching grease fittings on heavy machinery without repeated pumping.
• Fast flow rate: At about 5.7 oz/min the greasing process finishes faster than hand or low-pressure electric guns, saving time on fleet and shop work.
• Dual loading and large barrel: The 56 mm bore and 500 cc (17 oz) barrel accept standard 17 oz cartridges or bulk grease for flexible use and lower running cost.
• Extended hose and accessories: A 35.4 in flexible hose plus an 11.8 in hose, metal extension pipe, couplers, and a shoulder strap improve access and handling around tight fittings.
• Built-in LED: The separate-switch 1000-lumen LED provides targeted illumination for accurate greasing in dim work areas.

Who It's For

The ZUYIYI cordless grease gun is best for automotive technicians, farmers, and maintenance crews who already use Makita 18V batteries and need a portable, higher-pressure solution for tractors, construction gear, and service trucks. It suits users who prefer battery versatility and want to avoid corded limitations or manual pumping during frequent greasing tasks.

Those who should look elsewhere include buyers without Makita 18V batteries who do not want to purchase batteries separately, and hobby users who rarely grease equipment and would prefer a lower-cost manual gun. Also, users requiring an included battery-ready kit should consider models that ship with power packs.

Pros & Cons

Pros

• High 12,000 PSI pressure with 5.7 oz/min flow speeds up heavy-duty lubrication jobs.
• Dual loading (17 oz cartridge or bulk grease) reduces operating cost and adds convenience.
• Long 35.4 in hose and included accessories improve reach and versatility for hard-to-access fittings.
• Built-in 1000-lumen LED helps with precision work in low light.

Cons

• Battery not included, so the tool is not ready-to-run unless the buyer already owns a compatible Makita 18V battery.
• Quality feedback from some users is mixed, so buyers should inspect fittings and accessories on receipt.
