WORX WG550 20V LeafJet blower kit with 5.0 Ah battery review

A current 20V blower sold as a battery kit

The WORX WG550 is a handheld, battery-powered leaf blower for a shopper who wants the tool and its first power pack to arrive together. The exact U.S. listing identifies a 20V LeafJet blower and names one 5.0 Ah PowerShare battery and a 2 A charger in the package. That is a more useful distinction than treating “WG550” and “WG550.9” as cosmetic suffixes: the .9 listing is presented as tool-only. If you already own compatible PowerShare batteries, compare the two packages before paying for a second charger; if you do not, the base WG550 is the clearer one-box starting point.

What the airflow numbers do—and do not—tell you

WORX lists up to 620 CFM and 125 mph, describes a high-volume mode for broad clearing and a high-speed mode for wet or heavy debris, and provides variable speed with cruise control. The page does not give a separate airflow figure for each mode, so do not read 620 CFM and 125 mph as a guaranteed simultaneous operating point or as proof of a particular clearing rate. They are manufacturer specifications, not independent yard tests. Its claim of 51% more air output than the preceding WG543 is also a manufacturer comparison rather than a controlled result for every surface or leaf condition.

The controls are a better fit for mixed cleanup than a simple fixed-output sweeper: you can reduce airflow around corners or loose mulch, then select the faster stream for more stubborn debris. The speed-hold control may be welcome on a long pass because the page says it maintains a selected speed, but that does not make the blower self-propelled or remove the need to guide the nozzle. The manufacturer describes a brushless motor 2.0 and a one-button choice between volume and speed modes.

Weight and runtime depend on the included pack

The WG550 page reports 2.6 lb without a battery and 4.2 lb with its included 5.0 Ah battery. Those are two different loadouts; the larger ready-to-use figure is the relevant one for someone comparing how long the tool will be held one-handed. WORX advertises up to 35 minutes in low mode and 12 minutes at full power with that 5.0 Ah battery. Treat those as maker estimates under conditions it does not fully specify here, not a promise for every leaf load, temperature or battery age. The product page also says charging takes about 2.5 hours with the supplied 2 A charger. No manual-derived operating-weight or noise-at-distance value has been established for this review, so neither should be inferred from the headline copy.

Where it fits—and where it is the wrong tool

A cordless handheld is convenient for driveways, patios, decks and short trips around a small or medium property: there is no extension cord to drag or gasoline engine to start. WORX positions this model for those yard sizes, but the published runtime does not tell you whether one charge will clear your own lot. If you already use PowerShare, the battery platform can reduce the number of separate packs you need; check compatibility for the exact battery and tool revision rather than assuming every older pack has the same capacity or condition.

This is a blower only. It does not vacuum, mulch or collect leaves in a bag, so a shopper who wants to vacuum dry leaves or feed a collection hose should choose a different configuration. The corded WG524 is a more relevant alternative when bagged collection and its included LeafPro hose are central, though that changes the power source and keeps you near an outdoor cord route. If your main job is lighter patio cleanup and you do not need the higher published airflow, the smaller WG547 family has a lower listed 360-CFM ceiling. If the job regularly demands more power or longer sessions than this kit's stated runtime, compare a higher-capacity system instead of assuming a second battery-free specification guarantees more work per charge.

Package and evidence limits to check

The official page describes two airflow modes and a variable-speed/cruise-control arrangement, but it does not identify a typed accessory nozzle in the box list. Do not select the WG550 because you require a specific flat, round or concentrator tip unless the seller or manufacturer confirms that exact accessory. A separate 65 dB marketing reference is not accompanied here by a test distance or a clear A-weighted method, so it cannot satisfy a strict sound limit at 50 feet. The model manual is named on the product page but its linked PDF could not be recovered in this review; consult the current manual for assembly and safe use before operating.

Choose the WG550 when you want the current 20V blower, a documented cruise-control feature and a named 5.0 Ah battery/charger kit in one purchase. Choose WG550.9 only if the tool-only package is intentional and you have a compatible battery and charger plan. The manufacturer search listing and package copy for the tool-only page contain a generic battery FAQ that conflicts with the page's tool-only title; confirm the exact box contents before checkout if included power equipment is essential. Neither model is the right answer to a vacuum, mulch or collection requirement.
