Quick verdict
The 2727-21HD pairs Milwaukee's 16 inch M18 FUEL chainsaw with a 12.0Ah High Output battery and rapid charger. Milwaukee claims it out-cuts a 40cc gas saw and reaches full throttle in under a second, and owner feedback supports both. It is a premium kit whose value depends on whether that 12.0Ah battery will also power other M18 tools in your garage.

The Job-Site Chainsaw Comes Home
Milwaukee’s M18 FUEL chainsaw was designed for tradespeople who wanted a saw that ran on the batteries in their truck. The 2727-21HD is the kit version: the 16 inch saw with a 12.0Ah High Output battery and a rapid charger. Milwaukee’s claims are specific, faster cutting than a 40cc gas saw, full throttle in under a second and up to 150 cuts through a 6×6 on a charge, and the volume of professional owner feedback makes them easy to check.
This review draws on Milwaukee’s specifications and that owner feedback rather than on our own field work.
Cutting Performance
Owners consistently describe the saw as feeling like a strong 40cc gas unit: the POWERSTATE motor does not bog in hardwood, the chain pulls itself into the cut and there is no lag between trigger and full speed. Metal bucking spikes let you lever through larger rounds the way you would with a gas saw. The 16 inch bar is the limit. It handles the limbing and firewood work most homeowners do and the storm cleanup that pros face, but a 20 inch trunk needs two cuts.
Battery and Runtime
The 12.0Ah High Output battery is the key to the performance. Standard M18 packs run the saw but deliver less current, so power and runtime drop. With the kit battery, owners report a full session of firewood cutting on a charge, in line with Milwaukee’s 150-cut figure. The rapid charger refills the big pack faster than a standard charger, though it is still a matter of an hour or more rather than minutes.
Handling
With the 12.0Ah pack fitted the saw is heavier than small battery saws and about on par with a gas saw of similar bar length. Balance is good for bucking; overhead limbing for long stretches is tiring, as it is with any saw of this weight. The automatic oiler is reliable in owner reports and the chain tensioner is conventional.
Build Quality
This is a Milwaukee power tool, and owners describe it surviving truck beds, drops and rain. The housing is thick, the controls are positive, and the chain brake is a proper inertia unit with a front hand guard. Onboard storage holds the scrench.
Common Owner Complaints
Price is the main one. Some owners also note that the saw drinks bar oil and that the cap can seep during storage. A small number mention the 16 inch bar as limiting after they discovered how capable the saw was.
Alternatives to Consider
The EGO CS2005 offers a 20 inch bar with a battery included for less money. DeWalt’s 60V FLEXVOLT 20 inch saw suits DeWalt owners. For pure value, the Greenworks 80V 18 inch kit undercuts everything in this group.
Verdict
If M18 batteries already live in your garage, the 2727-21HD is an outstanding chainsaw and the 12.0Ah pack will serve your other tools too. If they do not, the kit price buys a longer bar and similar cutting power from EGO or Greenworks. Judge it by your battery drawer.

Milwaukee M18 FUEL 16 Inch Chainsaw Kit 2727-21HD FAQs
High Output packs deliver more current than standard M18 batteries, which is what lets the saw match gas performance. Smaller packs run it but with less power and much less runtime.
For limbing, storm cleanup and firewood from trunks under about 14 inches, yes. Large trunks need a two-sided cut or a bigger saw.
Milwaukee quotes full throttle in under one second. There is no pull cord, choke or warm-up.
Yes, an inertia-activated chain brake with a front hand guard, as on a gas saw.
