EGO ST1511LB POWERLOAD Trimmer and Blower Combo review

A POWERLOAD trimmer alongside EGO's 530 CFM blower

The ST1511LB pairs a 15-inch cordless string trimmer with POWERLOAD and a handheld 530 CFM blower. It is EGO's newer take on a two-tool 530 CFM combination, with the trimmer offering a telescoping aluminum shaft and button-activated line winding. EGO's 2026 US product catalog lists the combo with one 2.5 Ah battery and a 210 W charger. That makes it a strong fit for someone who needs both lawn edging and cleanup, but less attractive if a trimmer is already owned or if a longer-lasting included battery matters more than the newer trimmer features.

The blower's published maximum is the same nominal 530 CFM as the older ST1502LB/ST1503LB combo. The principal functional difference is not an airflow jump: it is the newer trimmer configuration and its package details. ST1502LB uses Rapid Reload, while ST1511LB uses POWERLOAD; the latter also has an adjustable telescoping aluminum shaft. Check the exact suffix because the separate ST1511T trimmer page and combo kit are related configurations rather than interchangeable retail packages.

Output control, attachment and weight

EGO states that the blower reaches 530 CFM and 110 mph. The combo page describes variable control from 260 to 400 CFM plus a turbo boost for maximum output. Its linked LB5300 manual lists low, high and boost values of 260, 400 and 530 CFM, with 50, 85 and 110 mph respectively. The manufacturer page and manual support a useful lower-output setting and a higher boost, but these specifications are not a test of clearing speed on wet leaves, twigs or gravel.

The LB5300 manual lists a 4.81-pound blower weight with its tube and without a battery. EGO does not document the complete assembled weight of this combo with the included 2.5 Ah battery installed. The battery adds weight, and the number shown in the manual should not be used as the user-carry weight. The manual does not list a force value in newtons for this blower, so shoppers with an essential force floor should choose a model with that value explicitly documented rather than infer one from 530 CFM.

There is also a useful package limitation around the outlet. The exact combo page lists airflow and speed control, but not a separate tapered, flat or spread nozzle. The linked blower manual's packing list names a blower tube, and EGO offers a shaped LB5300 nozzle as a separate accessory. The bundled tube is part of the blower; a second shaped attachment is not confirmed in the standard kit. If a nozzle is a must-have, verify it as an explicit retail package item or compare a kit that lists the relevant nozzle.

The included 2.5 Ah pack and two jobs

This kit supplies a single 2.5 Ah 56V ARC Lithium battery and a 210 W charger according to the 2026 EGO catalog. The pack can power either tool but not both at the same time. A compact pack can suit a short trimming session followed by ordinary cleanup, while a larger property or frequent boost use may call for a spare compatible battery. Capacity is only the battery's rating: grass height, debris, selected blower control and pack condition affect actual operating time.

The telescoping trimmer shaft can be adjusted to a user's preferred length, and the 15-inch cutting swath uses .095-inch dual line. POWERLOAD is intended to make line replacement quicker by winding the line after it is fed through and the button is pressed; ordinary line advancement during trimming remains distinct from that loading task. EGO's product page also describes a brushless motor and IPX4 weather resistance. The linked ST1510T-family manual describes the trimmer component and its assembly and operation, while the linked LB5300 manual covers the blower. They are separate tools and should be assembled, cleaned and maintained according to their respective instructions.

How it compares with the earlier 530 CFM bundles

Choose ST1511LB over ST1502LB when the POWERLOAD head and adjustable telescoping shaft fit your priorities; both packages are cataloged with a 2.5 Ah battery and 210 W charger, and both share a 530 CFM blower class. Choose ST1503LB if the larger 4.0 Ah battery is the important difference and Rapid Reload is acceptable. If neither trimmer is needed, compare the EGO LB5302 blower kit instead. If a higher published airflow ceiling or a different supplied nozzle matters more, look at another blower family rather than expecting the ST1511LB's control features to change its 530 CFM maximum.

The combo is a better value when the two jobs naturally follow one another: trim edges and obstacles, remove clippings, then clear leaves from a path or driveway. That is an operating plan, not a guarantee that one battery will cover every yard in one continuous session. Use lower airflow near light debris and boost when needed; an overpowered stream can scatter leaves into a bed or push them under parked items. Compare your expected work time to the manual's mode-specific runtime information rather than treating a top-line runtime claim as all-day capacity.

EGO gives a five-year limited tool and three-year limited battery warranty subject to its purchase and use terms. IPX4 is a resistance rating, not a reason to leave equipment outside in rain. Remove the battery before cleaning or inspection, clear grass and dust in line with the manuals, and use eye and hearing protection. Do not work around people, pets or open windows with a blower stream simply because the motor is quieter than a gas tool.

Bottom line

ST1511LB is for the buyer who wants the convenience of two cordless EGO tools and values POWERLOAD plus an adjustable trimmer shaft. It is not the best choice when a larger included battery, a documented blower-force rating, a confirmed shaped nozzle or a blower-only package is an essential need. Check that the carton is the ST1511LB combo and plan around one 2.5 Ah pack, the separate blower and trimmer operating modes, and the accessories actually listed for the kit.
