Model comparison
Compare EGO 56V handheld blower kits
These EGO 56V handheld kits share a battery platform and one-at-a-time nozzle setup, but differ in airflow, included pack, charger description, controls and accessories. Begin with the box contents and the way you will carry the blower. A CFM headline is not a reliable substitute for a particular nozzle or an installed-weight figure.
Lower output: 480, 530 and 580 CFM
The LB4803 is the 480 CFM kit with a 2.5 Ah battery and standard charger. Its manual lists 5.16 lb with tube and without battery, the heaviest bare-body figure in this reviewed group. It does not list a shaped nozzle or maximum force in newtons. The LB5302 also has a 2.5 Ah kit battery and a standard charger, with 530 CFM maximum. Its manual describes 260, 400 and 530 CFM settings; the blower tube is listed but a separate shaped nozzle is not. Because its manual does not state force in newtons, a force floor cannot be confirmed.
The LB5804 steps up to 580 CFM and includes a 5.0 Ah battery, standard charger, tapered nozzle and flat nozzle. Its manual lists 18 N maximum force and 4.77 lb without the battery. This is a meaningful box-content step from the two smaller-output kits: both shaped nozzle choices are included and the pack is larger, but the spread nozzle and shoulder strap remain separate accessories. A 5.0 Ah battery does not guarantee a fixed runtime; compare the operating mode behind each manufacturer's estimate.
Middle ground: 615, 650 and 670 CFM
The LB6151 pairs a 2.5 Ah battery and standard charger with a tapered nozzle. Its manual lists 615 CFM, 18.5 N and a 4.74 lb body without battery. The LB6504 includes a 5.0 Ah pack, standard charger, flat and tapered nozzles, and a 650 CFM maximum; its manual lists 21 N and 4.77 lb body-only. The spread nozzle is not in that kit’s manual packing list.
The LB6703 gives a different compromise: 670 CFM with a 4.0 Ah battery, 320 W charger, tapered and spread nozzles. Its manual lists 21 N maximum force and 4.8 lb without the battery. It does not include a shoulder strap. A buyer choosing between the 6504 and 6703 may care more about the 6504’s larger pack and flat nozzle or the 6703’s spread nozzle and faster-listed charger than about the 20 CFM difference.
Higher peaks: 765 and 880 CFM
The LB7654 is the one-battery kit with a 5.0 Ah pack, 320 W charger, tapered and spread nozzles, and strap. Its manual lists 765 CFM, 26 N and 4.6 lb body-only. The related LB7654-2 is a distinct two-battery package with a rapid charger, while LB7650 is tool-only. The product page advertises 200 mph, but the linked LB7650 manual lists 195 mph with the tapered nozzle; the review preserves that difference.
The LB8803-2 includes two 4.0 Ah batteries, a 320 W charger, both nozzle shapes, a strap and a digital status display. Its manual lists 880 CFM, 30 N and a 4.9 lb body without battery. Only one pack is mounted on the blower at a time. It is the distinct option for a two-battery kit and on-tool display, not a promise that two packs are used simultaneously or that a high peak gives longer runtime.
Older listing: keep the suffix and status clear
The LB5754 page is retained as an identification reference because EGO marks the package discontinued. The LB5750 manual lists 575 CFM, 142 mph, 4.8 lb without battery, a spread nozzle and a shoulder strap, but does not publish force in newtons. Its product page has a conflicting technical-spec line about nozzles. It is not a current buying match. For a current spread-nozzle kit, compare the LB6703, LB7654 and LB8803-2 instead.
Across this group, manual-listed body weight excludes the battery and nozzle, and the operating-weight field is not established for these exact kits. Do not infer the carried weight by adding mismatched battery data. Use the comparison tool for stated specifications and the finder for a hard equipment or airflow requirement; leave optional weight limits blank unless the documentation matches your intended setup.
When a trimmer-and-blower package makes sense
The ST6151LB bundles a 15-inch trimmer with a 615 CFM blower, one 2.5 Ah battery, standard charger and tapered nozzle. It fits a buyer who needs both tools and can make one battery serve two jobs in sequence. The separate blower-only LB6151 is the simpler comparison if trimming is already covered.
The ST6703LB is the higher-output combo: 670 CFM, a 4.0 Ah battery, 210 W charger, and tapered plus spread nozzles. Its blower manual lists 21 N and 4.8 lb bare; battery-installed weight is not given. EGO’s page differs on the lower end of the variable-speed dial, and its advertised runtime does not map neatly to the manual’s low/high/boost estimates. Compare the actual kit contents and use the larger pack/nozzle set only if they fit your routine; the blower-only LB6703 avoids buying a second trimming tool.
In either combo, one battery is shared between the two tools, not a dedicated pack for each. The two model names are package identities, and neither is a backpack blower. A lower stated maximum is not automatically a worse choice for a small path or planting bed where controlled air matters more than peak output.
