Design and features

The Alloyman CS-BM11 cordless chainsaw arrived in a nicely displayed box.

Inside the cardboard cover is a fitted case. I am especially fond of gadgets that include cases that make organization and storage effortless.

The case is secured with a pair of gutsy latches.

Surprise, surprise! Alloyman includes a pair of work gloves and safety goggles. Please, dear Gadgeteers, use them with diligence. They’re in the box so there’s no excuse not to use them!  Your hands deserve to be shielded from sawdust and the inevitable snapping of branches, and, for me, when working outside are indispensable when there is a chance I might accidentally touch a spider.  As for the goggles – eyesight is precious and should always be protected, especially when using a tool capable of blasting toothpicks towards your face.  Okay, in fairness, the CS-BM11 emits copious amounts of sawdust, but you get the point.

Another pleasant surprise is the inclusion of not one, but two removable batteries. Wooo!  As a big fan of rechargeable tools, I can attest that running out of juice halfway through a work project is the pits. The extra battery means one can be working while the other receives a respite with enthusiastic electrons. Well done, Alloyman.

The coaxial charging port is located on the battery.

Power is supplied through a wall-wart transformer.

An LED indicates changes from red to green when charging is complete. I measured a bit less than 90 minutes to full capacity yielding a commendable 37 minutes of continuous run time. Of course, cutting wayward branches won’t require uninterrupted use so actual work time should be much longer.

There’s a handy button with a four-segment LED to let you know how much power is left in the battery.

 The battery slides into the saw and securely latches. To detach, press the yellow button.

Recessed terminals in the battery engage with the power connections on the saw.

There is a safety latch on the side of the saw that must be pressed to operate and will automatically engage when the trigger is released. It extends through the saw handle and works for both righties and lefties.

The Alloyman CS-BM11 Cordless Chain Saw’s motor is single-speed and sends the saw chain whirring at speeds over 4000rpm.  It’s very fast… and dangerous… and useful!  The first time I fired it up it was obvious this was NOT a toy!  Let’s be careful out there, folks!

The body of the saw feels strong and feels comfortable to use. There is a protective guard around the handle.

The chain bar is six inches long. I was super happy to find that bar oil isn’t needed. This keeps the tool much cleaner than other chain saws I own and reduces operating time and maintenance. Excellent!

Atop the blade is a spring-loaded safety cover. It pivots out of the way when cutting deeper stuff.

The CS-BM11 easily cut through a 1.75-inch branch in a touch over three seconds.

A larger log with a diameter of about four inches took about 15 seconds.

When the time comes to adjust or replace the chain, the saw can be disassembled without tools. Alloyman even includes a spare chain! Bravo!

What I like

  • Two batteries! Yay!
  • No bar oil!
  • Uncomplicated operation
  • Cuts remarkably well
  • Extra chain included
  • No tools are needed for maintenance

What I’d change

  • Nothing

Final thoughts

With two batteries, a carrying case, gloves, safety goggles, and under $80, the Alloyman CS-BM11 mini chainsaw is an outstanding value!  As I’ve been doing fall yard cleanup, I used it to trim and shorten branches that were too long to fit into my backyard fire pit and remove some tree roots that were dinging up my lawn mower blades.  I found deploying and maintaining the saw is straightforward and it’s an ideal tool for small yardwork.  I imagine having an Alloyman Cordless Chain saw handy on my next camp trip will make stoking the fires painless. Bring on the s’mores!  Great job and thank you Alloyman!
