20 October 2026

How we scored them

Each gun is scored on performance, build, value, safety and warranty, with the weights published on our How We Pick page. A spec the listing does not publish scores nothing.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

What the listings tell you

Pressure is the headline spec. The NEIKO states 4500 PSI, the highest here. The Powerbuilt, Thorstone and Better Boat each state 3000 PSI. The Meonum states no pressure figure. For stiff fittings, the NEIKO’s stated 4500 is the number; for routine greasing, the 3000 PSI trio are the stated picks.

Loading options differ. The NEIKO states cartridge, bulk fill and dispenser pump with an easy push air release valve. The Powerbuilt states standard 3-ounce cartridges, bulk suction fill or dispenser pumps with a push-button air bleeder. The Thorstone states bulk loading up to 3 ounces. The Better Boat states standard 3-ounce tubes. The Meonum states a preloaded gun with a removable back cover for refills.

Buying guide: choosing the best small grease gun under 50

Start with the pressure. The NEIKO states 4500 PSI with a stated 1.5-ounce output per 100 strokes and 85 grams of NLGI number 2 grease included. The Powerbuilt, Thorstone and Better Boat state 3000 PSI each. The Meonum states no pressure: it is the chainsaw-specific pick with a transparent body that shows the remaining grease.

Then check the design. The NEIKO, Powerbuilt and Better Boat are pistol grips: the NEIKO states a non-slip rubber grip with an ergonomic T-handle, the Powerbuilt states a non-slip rubber handle with an ergonomic T-grip, and the Better Boat states one-handed pistol grip operation. The Thorstone is the push-type: a spring-loaded push-button one-hand design with a needle nozzle for small fittings. The Meonum is the chainsaw gun: plastic body with a steel tip, stated for bar tips and clutch needle bearings.

Weights are stated on all five: 1.72 pounds for the NEIKO and Better Boat, 1.2 pounds for the Powerbuilt, 9.9 ounces for the Thorstone and 5.28 ounces for the Meonum. The Thorstone and Meonum are the lightest by far. No warranty term is stated on any of the five.

Pressure and output

The NEIKO states the highest pressure here: up to 4500 PSI with a stated 1.5-ounce output of grease per 100 strokes. The Powerbuilt, Thorstone and Better Boat each state 3000 PSI. The Meonum states no pressure figure; it is the chainsaw-specific pick rather than a pressure pick. If the job is stubborn fittings on heavy equipment, the NEIKO’s stated 4500 PSI is the number to compare against.

Loading options

How the gun takes grease matters every time you refill. The NEIKO states three ways: standard 3-ounce cartridges, bulk loading with a suction fill, or a dispenser pump, plus an easy push air release valve for eliminating air pockets. The Powerbuilt states the same three: standard 3-ounce cartridges, bulk suction fill or dispenser pumps, with a push-button air bleeder valve. The Better Boat states compatibility with all standard 3-ounce grease tubes and notes its marine grease is available in a 3-pack of mini cartridge refills. The Thorstone states easy refilling with bulk loading up to 3 ounces. The Meonum is preloaded with a removable back cover: when the grease runs out, open the cover and refill it with chainsaw bar tip lubricator.

Nozzles, extensions and hoses

Reach decides which gun fits tight fittings. The NEIKO states a 5-3/4-inch straight metal extension with a zerk fitting coupler. The Powerbuilt states a 6-inch straight metal extension with a zerk coupler that attaches at 0 or 90 degrees. The Better Boat states multiple tips for zerk fittings, extensions and a flexible grease gun hose with a cover for reaching difficult areas. The Thorstone states a needle nozzle, which the listing calls perfect for lubricating small fittings and devices. The Meonum states a steel tip on its chainsaw gun. On air pockets, the NEIKO states an easy push air release valve and the Powerbuilt states a push-button air bleeder valve to remove air pockets with ease.

Grease included

Two listings state grease in the box. The NEIKO states 85 grams of NLGI number 2 grease included. The Better Boat states a 3-ounce cartridge of marine-grade grease for immediate use. The Meonum states preloaded lubricant with a transparent body so the remaining grease is visible without opening the lid. The Powerbuilt and Thorstone state no grease included; the Thorstone’s package states an extra stick for easy assembly.

Materials and build

The NEIKO states a cold drawn steel tube with a leak free design, a non-slip rubber grip handle, an ergonomic T-handle for easy loading, and a strong spring with a sealed O-ring for smooth grease flow. The Powerbuilt states a cold-drawn steel barrel with a leak-resistant design, a non-slip rubber handle and an ergonomic T-grip. The Better Boat states heavy-duty aluminum alloy with a high pressure O-ring, stated to protect against corrosion in marine conditions. The Thorstone states a zinc-plated die-cast head unit for durability with a spring-loaded push-button design. The Meonum states a high strength plastic body with a steel tip that withstands temperature changes and is not easy to destroy by dropping on hard surfaces.

Applications each listing states

The NEIKO states light and heavy equipment: tractors, cars, trucks, motorcycles, bicycles, u joints, lawnmowers, bush hog, log splitter, chainsaws, bearing packers and axles. The Powerbuilt states tractors, trucks, cars, motorcycles, lawnmowers, chainsaws, u-joints and axles. The Better Boat states marine wheel bearing and automotive use. The Thorstone states air tools like impact wrenches, hinges, light-duty lift equipment, mechanical joints on bicycles, chainsaws, motorcycles and small bearings. The Meonum states chainsaw bar tips, chain saw clutch needle bearings, brush cutters, hand tools and lawn equipment. Match the stated applications to the machine you grease most.
