My EGO LB6504 review verdict is a buy for a quarter to half an acre of lawn and yard cleared one pack at a time, and a pass for wet leaf mats across an acre. I clear the leaves from the lawn and yard around our family house every autumn, so I judge a blower by what one pack gets done. According to EGO, the 5.0 Ah pack gives about 30 minutes on high and takes about 100 minutes to refill, so I charge it overnight. Below I cover the box, setup, power, runtime, noise, weight, upkeep and the alternatives.

EGO LB6504 Review and My Verdict in Brief
I recommend the LB6504 for a lawn and yard of a quarter to half an acre, cleared in jobs that one pack can finish. The full 5.0 Ah pack is its strength and the standard charger is its weak point, because a refill takes about 100 minutes. Skip it if you want the pack back on the blower before lunch, or if your main job is wet leaf mats across an acre.
- Who it is for: owners of a lawn and yard who charge overnight and clear in one-pack jobs.
- What it does best: it runs about 30 minutes on high from one pack and moves dry leaves and light debris well.
- The main trade-off: a 100-minute recharge and about 9.7 lb in one hand.
What Comes in the Box
The LB6504 is a kit: the LB6500 blower, one 56V 5.0 Ah battery and the standard CH2100 charger. For anyone new to the 56V line, the EGO 650 blower with battery and charger in one box is the simplest way in.
Two sister versions use the same blower. The LB6503 comes with a 4.0 Ah pack, and the bare LB6500 comes with no pack at all. If you already own EGO 56V batteries, the EGO 650 CFM Blower tool only version saves you a second battery and a charger you do not need.
According to EGO, the kit includes a tapered nozzle and a flat nozzle but no shoulder strap, which EGO sells as a separate accessory.
Specifications at a Glance
The EGO 650 CFM blower specs shift with the nozzle and the pack, so each figure below carries its condition. Run time on high and charge time are the two rows that decide the purchase.
| Spec | Figure and condition |
|---|---|
| Airflow on boost | 650 CFM at the nozzle |
| Airflow on the dial | 225 to 470 CFM |
| Air speed | 180 mph with the tapered nozzle, 160 mph without it |
| Rated force | 21 N, about 4.7 lb of push |
| Battery | 56V, 5.0 Ah, 280 Wh |
| Run time per pack | About 200 min low, 30 min high, 15 min boost, per EGO |
| Charge time | About 100 min on the standard charger, per EGO |
| Weight | 4.77 lb tool only, about 9.7 lb with the kit battery |
| Noise | 64 dB on EGO’s box, with no distance given |
| Warranty | 5 years tool, 3 years battery and charger, 1 year commercial use |
Setup and First Use
Assembly needs no tools. The EGO 650 CFM blower manual walks through the same order I use:
- Take the battery off the blower, push the tube onto the housing until it clicks, and snap the nozzle onto the tube.
- Charge the pack fully before first use. The gauge on the pack shows the charge in five lights.
- Slide the pack in until it clicks, and check the screws and caps for looseness before each session.
A new pack may show a flashing red light on the gauge, which means it is nearly empty and needs its first charge.
The Trigger, Speed Dial and Boost Controls
The trigger gives variable speed, and the dial on the handle locks a speed so the trigger can rest. The boost button raises the speed to its maximum only while you hold it, and it cannot be locked on.
On the lawn I set the dial near the middle, let the trigger rest, and tap boost for the clumps of leaves that gather at the base of the shade trees. The dial sits to one side of the handle, so I shift my grip a little to reach it with my right hand and set it before I start a pass.
EGO LB6504 Review of Performance on Leaves and Light Debris
EGO rates the push at 21 N. The blower reaches about 20 N on boost and about 11 N on high, so boost nearly doubles the force. Hard surfaces such as driveways, walkways and decks are where a blower of this size is at home.
Dry Leaves and Storm Debris
Dry leaves and light debris are the work this blower does well. The quarter acre around our house has three shade trees, and on high the blower sweeps the dry leaves toward the lawn edge without fuss. In spring I use it for the twigs and seed pods that storms leave on the grass, so the mower has nothing to throw.
I work around the edges of a pile instead of blowing into its middle, and I loosen packed debris with a rake first.
Wet Leaves and Hard Surfaces
Wet leaves stick by surface tension, so they need volume under the edge, and 650 CFM at 21 N runs short there. After a night of rain I found a wet mat on the concrete work pad that boost lifted at the edge and high only slid across the surface. A thin wet layer moves on boost, while thick soaked clumps need a rake first.
EGO LB6504 Review of Runtime and Charging
According to EGO, the 5.0 Ah pack gives about 200 minutes on low, 30 on high and 15 on boost. The EGO 650 CFM Blower battery stores 280 Wh, and boost drains it about twice as fast as high, so I keep boost for the stubborn corner. EGO’s headline of up to 90 minutes is an average across modes, and I plan with the minutes per mode.
The slow part is the refill. According to EGO, the standard charger needs about 100 minutes for a full pack, against about 40 on its rapid charger. A modelling study of fast-charge scenarios tied harder, faster charging to more thermal stress and a shorter cycle life (1), so the speed of a rapid charger comes with some extra wear.
I put the pack on the charger after supper, and it is full long before bed. If a leaf cleanup adds up to two hours on high, that is about four packs at EGO’s 30 minutes each, and the 100-minute charger decides whether a second pack is a luxury or a need.
Noise, Weight and Balance
EGO prints 64 dB on the box and gives no distance, so I do not read it as the level at your ear. At the ear the blower measures about 88 dB(A) on boost, about 84 on high and about 68 on low. NIOSH sampling of landscaping workers found significantly more noise from fuel-powered blowers than from battery ones (2), and a study of groundskeepers measured equipment peaks from 76 to 109 dBA (3), so boost belongs behind hearing protection.
Protection
Wear eye and hearing protection on every pass, a dust mask in dusty work, and keep children and pets well clear of the stream.
With the kit pack the blower weighs about 9.7 lb, and the pack makes up roughly half of it. A gallon of water weighs a little over 8 lb, so think of a full jug and a bit more held out on one arm. I notice it most on the walk from the lawn to the yard, when the tool hangs from one hand and the pack pulls the wrist down.
Boost also pushes back against the hand, so I use it in short taps and change hands between packs. A study of groundskeepers found that those who use handheld blowers and chainsaws build up far higher lifetime hand-arm vibration doses than office workers (4), so breaks and a change of hands are cheap habits.
Maintenance, Storage and Battery Care
The routine is short. I take the pack off before cleaning, wipe the plastic with a clean cloth, and clear the air intake so nothing starves the fan.
Winter is where a battery ages quietly. A modelling study of 36 months in storage at 131 F and a nearly full charge found heavy degradation (5), and lab tests on cells tie capacity loss to age and to the charge window (6). In December I carry the pack indoors, off the tool, leave it about half charged, and give it a full charge in spring before the first storm cleanup.
Common Problems and How to Fix Them
Most stops have a plain cause. Work through these before you call for service:
- Stops mid-job: the pack or the tool is running hot. Let both cool, and the blower works again.
- Dead or weak: a depleted pack needs a charge.
- Will not charge in the cold: a cold pack waits to charge until it warms up, so bring it indoors first.
- Airflow drops: a blocked intake cuts the air. Take the pack out and clear the debris. A worn fan needs the EGO service center.
- Abrupt stops or early failure: some owners report them after a couple of years. If it keeps happening, contact EGO support.
Warranty and Support
The EGO 650 CFM blower warranty covers the tool for 5 years and the battery and charger for 3, and it drops to 1 year for professional or commercial use. Claims go through EGO customer service with the original dated receipt, and you pay the shipping to the service center, so keep the receipt with the manual.
Who Should Buy It and Who Should Skip It
The LB6504 rewards a modest yard and an overnight charging habit.
- Buy it if you clear a lawn and yard of a quarter to half an acre in one-pack jobs.
- Buy it if you charge overnight, so the 100-minute refill costs you nothing.
- Buy it if your work is dry leaves, clippings, twigs and light debris on lawns and hard surfaces.
- Skip it if you need the pack back on the blower within the hour.
- Skip it if your main job is wet leaf mats or acre-size leaf cleanups.
- Skip it if 9.7 lb in one hand wears you out before the pack does.
Drawbacks to Know About
Four limits count in daily use, each with what to do about it:
- Weight: about 9.7 lb with the pack. Split long jobs into short runs and switch hands.
- Slow charge: about 100 minutes per pack. Charge overnight or add a second pack.
- Short boost: 15 minutes per pack, and it cannot be locked on. Save it for stubborn debris.
- Loud on boost: wear hearing protection on every pass.
How It Compares With Alternatives
Three EGO kits sit closest to the LB6504, and my leaf blower guides cover the wider field. The LB6703 and LB7654 kits sit in the same price tier as the LB6504 or one step below it, so the slow charger does not buy you a lower price.
| Kit | Airflow | Battery | Charger |
|---|---|---|---|
| LB6504 (this review) | 650 CFM | 5.0 Ah | Standard, about 100 min |
| LB6703 | 670 CFM | 4.0 Ah | Faster, about 55 min |
| LB7654 | 765 CFM | 5.0 Ah | Faster, about 70 min |
| LB6151 | 615 CFM | 2.5 Ah | Standard |
EGO LB6703
The EGO Power+ LB6703 670 CFM Blower Kit refills in about 55 minutes and moves a little more air, but its 4.0 Ah pack runs about 24 minutes on high against 30. Pick it if you want the pack back on the blower quickly.
EGO LB7654
The EGO Power+ LB7654 765 CFM Blower Kit moves 765 CFM with a rated 26 N, keeps the 5.0 Ah pack and charges faster. Choose it if you want more push and a quicker refill from the same pack.
EGO LB6151
The EGO Power+ LB6151 615 CFM Blower Kit is the smallest and cheapest of the four, with a 2.5 Ah pack and 615 CFM. Take it for a deck, a patio and a small lawn, where jobs last minutes.
My Recommendation on the EGO LB6504 Kit
Buy the LB6504 if you are a homeowner with a quarter to half an acre of lawn and yard, you want a full 5.0 Ah pack, and the charger can sit on the shelf overnight. A pack gives about 30 minutes on high, and the cost is a 100-minute refill and about 9.7 lb in one hand.
Take the LB7654 instead if the same 5.0 Ah pack with 765 CFM, 26 N and a faster charger fits your tier, because it fixes both weak points. Choose the LB6703 if you need the pack back on the blower in under an hour and can live with a smaller 4.0 Ah pack. My EGO LB6504 review verdict is a buy if you charge overnight and clear a quarter to half an acre on one pack, and a pass if you need a second round the same morning.
Frequently Asked Questions
Is 650 cfm good for leaf blower?
650 CFM is good for a leaf blower on a lawn, drive and yard of up to half an acre, where it moves dry leaves, clippings and light debris with ease. It is too little air for thick wet leaf mats in volume, so plan on a rake or a stronger blower for those.
How powerful is 650 cfm?
650 CFM is the volume of air the LB6504 moves at the nozzle on boost, a mid-power step in the EGO line. EGO rates the push at 21 N and the speed at 180 mph with the tapered nozzle, while the speed dial covers 225 to 470 CFM across its range.
Which Ego blower is most powerful?
The most powerful EGO handheld blower is the 880 CFM kit, which comes with two batteries to feed its higher power draw on every job. The LB6504 sits a step below it and below the 765 and 670 CFM kits, which makes it a tool for a house lot and its yard.
Why does my Ego leaf blower keep shutting off?
An EGO leaf blower shuts off when the pack or tool runs hot, and it works again once both cool, while a cold pack will not charge until it warms up. A blocked intake only cuts the airflow, so clear it, and if the LB6504 keeps stopping, contact EGO support.
What are the key differences between the Ego 650 and 765 leaf blowers?
The EGO 765 blower moves 765 CFM with 26 N of rated push, while the 650 moves 650 CFM with 21 N of rated push. Both kits carry a 5.0 Ah pack, but the 765 kit ships with the faster CH3200 charger and the 650 kit with the standard one.
