The Toro 60V Max Flex-Force platform, and the only honest watt-hour on this site
Every other brand leaves you to multiply the marketing voltage. Toro does the sum for you, and the answer is 11% lower.
Affiliate disclosure: we earn a commission if you buy through our links, at no extra cost to you. It never changes which product we rank first — here is how we're funded.

We have not tested these units. Every spec on this page comes from the manufacturer's own documentation and is linked to it. Every computed figure is arithmetic you can redo. Prices are checked daily — last verified October 7, 2026. Here is exactly how we pick.
Every watt-hour figure on this site except Toro's is our own multiplication. We take a brand's advertised voltage, multiply by amp-hours, call it a nameplate figure and say so every time. Toro is the single exception: it publishes the watt-hours itself, and it publishes the voltage it used to get there. Put those two facts together and you have the correction factor that applies to every other number in our registry.
The short answer
The pack lineup, as Toro publishes it
| Pack | Amp-hours | Toro's published watt-hours | Implied voltage | Nameplate figure we would have computed |
|---|---|---|---|---|
| 88620 | 2.0Ah | 108Wh | 108 / 2.0 = 54V | 60 x 2.0 = 120Wh |
| 88925 (replaces 88625) | 2.5Ah | 135Wh | 135 / 2.5 = 54V | 60 x 2.5 = 150Wh |
| 88640 | 4.0Ah | 216Wh | 216 / 4.0 = 54V | 60 x 4.0 = 240Wh |
| 88660 / 88960 | 6.0Ah | 324Wh | 324 / 6.0 = 54V | 60 x 6.0 = 360Wh |
Amp-hours and watt-hours transcribed from Toro's own battery product pages, all four cited below. The 4.0Ah page states "60-Volts maximum" with "54-Volt typical usage" and the 2.0Ah page states "60-Volts maximum and 54-Volt typical usage, actual voltage varies with load". The implied-voltage and nameplate columns are our arithmetic.
Four packs, four independent confirmations of the same thing: Toro's watt-hour figures are computed at 54 volts. The last column is what this site would have published for those packs if Toro had stayed quiet like everyone else.
The 11% correction, and what it does to every other page
This is the most useful thing the Toro platform gives a reader, and it has nothing to do with buying a Toro.
The pack you can actually buy, and what it is for
Toro publishes 135 watt-hours for the 2.5Ah pack, a 3-year limited warranty, compatibility with the 75+ tool Flex-Force lineup covering commercial-grade handheld tools, walk mowers and snow blowers, and a list price of $226.59. It publishes no weight and no charge time, and the 2.5Ah page does not repeat the 60V-max / 54V-typical statement its 2.0Ah and 4.0Ah siblings carry — though its own 135Wh divided by 2.5Ah returns the same 54V regardless.
What it is for: handheld tools. 135 watt-hours is roughly 42% of what Toro's own walk mower ships with, and that mower claims 45 minutes from its 324Wh pack. Fitted to a trimmer or a blower it is a sensible pack; fitted to a mower it would not finish a small lawn. The sizing logic is the same one in bare tool or kit.
It is also the only Toro product on this site with a verified live price — our daily search finds no title match for the 21356 mower or the 51621 blower — so it is the one place the money side of this platform can be checked at all.

Who this platform is for, and who should skip it
It suits you if you want a platform whose energy claims can be audited rather than inferred; you need a mower that stores vertically, because the 21356 publishes SmartStow and a one-car garage is a real constraint; you want snow and lawn on one pack, as the Flex-Force lineup covers both seasons; or you buy through a Toro dealer and value that over a retailer counter.
Skip it if you want the broadest catalog — 75+ tools is a lot and EGO and Ryobi both go further, particularly into pressure washers, inflators and riding mowers. Skip it if charge speed matters: the 21356 publishes a 150 minute recharge, which is the slowest figure in our registry by a wide margin and is three times the EGO trimmer's 50 minutes. And skip it if you want the biggest single pack available, which is EGO's 7.5Ah at 420Wh nameplate.
The mower: 324 published watt-hours and 45 minutes
Toro publishes a 21 inch deck in 14-gauge steel, a 60V Max L324 pack at 6.0Ah and 324Wh, a 150 minute charge time, up to 45 minutes of runtime, Personal Pace variable-speed rear-wheel drive, 66 lb and SmartStow vertical storage.
Three things carry this machine: the honest energy figure, 45 minutes from it, and the 14-gauge deck — the only steel gauge any walk-behind in our registry publishes. The 66 lb weight is published too, which puts it on best lightweight mowers where the Kobalt cannot appear at all.
The honest gaps: 150 minutes to recharge is the slowest in the registry, and Toro publishes no acreage rating, so the 324Wh has to borrow the 640Wh-per-acre figure derived from Greenworks and Kobalt to mean anything in lawn-size terms. We hold no verified live Amazon price for the 21356 — our daily search returns no title match — so its link is a tagged search and carries no number.

The Toro tool in our registry that is not on the platform
Worth knowing if you are shopping the brand rather than the battery: Toro's best-spec blower in our registry is corded, not Flex-Force. The 51621 UltraPlus publishes 340 CFM blowing, 405 CFM in vacuum mode, up to 260 MPH, up to 97% leaf volume reduction, 13 lb and a 2-year warranty. The 97% figure converts to roughly a 33:1 mulch ratio, the best shredding figure we hold from any maker.
It belongs here as a caution rather than a recommendation: buying into Flex-Force does not get you Toro's whole catalog, and the brand's strongest leaf tool needs an outlet. The comparison is in best leaf vacuum mulchers and corded or cordless.

How it lands against the other four platforms
- EGO vs Toro — the largest single pack against the only published real watt-hours. The nominal-versus-max trap is explained there too.
- Ryobi vs Toro — Ryobi publishes no real watt-hour figure at all, which is the comparison in one line.
- Toro vs Greenworks — 324 published against 320 nameplate, which is the single clearest example of why the convention matters.
- Kobalt vs Toro — the most installed nameplate energy against the most checkable.
- Charging times — where Toro's 150 minute mower recharge sits against every other published figure.
What we cannot tell you
We have not used a Toro Flex-Force tool. Toro publishes no weight for any of the three packs, no charge time on the pack pages themselves, and no nominal-voltage statement on the 6.0Ah page — the 54V figure comes from the 2.0Ah and 4.0Ah pages, and we are applying it to the 6.0Ah because its own 324Wh divided by 6.0Ah returns the same 54V. The 75+ tool count is Toro's claim, not a list we have verified item by item. Toro publishes no acreage rating for the 21356, so every lawn-size statement about it on this site borrows a figure derived from two other brands. The battery warranty beyond 7.5Ah is published as additional coverage without a single clean number, and Toro directs warranty questions to a dealer. And the 11% correction factor on this page is arithmetic from published voltages, not a measurement of cell chemistry under load — actual delivered energy varies with temperature, age and draw, and no maker on this site publishes any of that.

135 watt-hours, published outright by the maker -- the fourth Toro pack to confirm that its energy figures are computed at 54 volts, not 60.

135Wh / 2.5Ah = 54V. The same division on Toro's other three packs returns 54V every time: 108 / 2.0, 216 / 4.0 and 324 / 6.0. Four packs, four confirmations. A nameplate figure computed at the advertised 60V would have called this pack 150Wh, which is 11.1% higher than what Toro itself publishes -- and that 11.1% is the correction factor that applies to every other brand's watt-hour figure on this site.
What the numbers favor
- Publishes a true watt-hour rating, which no other brand in our registry does for any pack
- A fourth independent confirmation that Toro's energy figures use nominal rather than max-charge voltage
- Runs any of the 75+ tools in the Flex-Force lineup, lawn and snow
- 3-year warranty, level with EGO and Kobalt
- Toro publishes a list price, so the live figure has something to be measured against
What they don't
- The 2.5Ah page does not repeat the 60V max / 54V typical statement its 2.0Ah and 4.0Ah siblings carry
- No weight and no charge time published
- 135Wh is a small pack -- a third of what the Flex-Force walk mower's 6.0Ah pack carries
- Warranty detail requires contacting Toro rather than reading the page
you are buying the pack to run a mower. 135 watt-hours is a handheld-tool pack; Toro's own walk mower ships a 324Wh 6.0Ah and claims 45 minutes from it, so this one would not finish a small lawn.

Toro labels the pack 60V Max 6.0Ah and publishes 324Wh. 324 / 6.0 = 54V -- the nominal voltage, not the 60V max-charge figure on the sticker. Every brand's 'max volts' is roughly 11% above nominal, so a nameplate watt-hour number is always about 11% optimistic. This is the single most useful spec on this page.
What the numbers favor
- Publishes a real watt-hour figure (324Wh) instead of leaving you to multiply the marketing voltage
- 45 minutes from 324Wh, against Greenworks' 33 minutes from a nameplate 320Wh
- 14-gauge steel deck, the only steel deck spec published on this page
- SmartStow vertical storage -- a genuine constraint solver in a one-car garage
What they don't
- 150-minute recharge is the slowest here by a wide margin
- Toro's 60V line is narrower than EGO's or Ryobi's, so the platform grows less far
you are buying into a platform rather than a mower. Toro builds excellent mowers; the 60V Flex-Force tool range is not the one to bet a decade of yard tools on.

Toro 51621 UltraPlus Leaf Blower / Vac
Toro · Corded (120V) · Our score 8.4/10
#ad No verified live price right now, so we show none rather than a stale one. How we're funded.
A published 97% volume reduction -- twice the mulch ratio of anything else here -- and 405 CFM in vacuum mode.
Published specs
| Power | Corded; amperage not published |
|---|---|
| Air volume, blow | 340 CFM |
| Air volume, vacuum | 405 CFM |
| Air speed | Up to 260 mph |
| Leaf reduction | Up to 97% |
| Weight | 13 lb |
| Bag capacity | Not published |
| Warranty | 2-year limited |
Source: 340 CFM UltraPlus Corded Electric Leaf Blower/Vac (51621), toro.com
A 97% volume reduction leaves 3% of what went in, and 1 / 0.03 = 33. So Toro's claim is a 33:1 ratio against the 16:1 WORX publishes -- about twice the shredding, stated a different way. Two makers, two units, same physical quantity: this is the conversion that makes them comparable.
What the numbers favor
- 97% reduction converts to roughly 33:1, the best shredding figure we hold
- Publishes CFM separately for blow and vacuum modes, which few do
- 260 mph nozzle speed for wet leaves stuck to a driveway
- Metal-free operation aside, the vacuum tube swaps without tools
What they don't
- 13 lb is 50% heavier than the WORX
- Amperage and bag capacity are not published
- 2-year warranty against 3 on the WORX
you need to carry the tool one-handed for long stretches. Thirteen pounds at arm's length is a different job from 8.6.
