If you already own Dewalt 20V batteries, you’ve got three solid options for a reciprocating saw: the DEWALT DCS387B, the VocoxGpow, and the Funnywhale. The DEWALT is a bare tool with a 1-1/8-inch stroke and 0-2,900 SPM, while both compatibles push 3,500 SPM with brushless motors.
This comparison is for anyone who wants to skip buying a new battery system and just grab a saw that clicks into their existing Dewalt gear. The real trade-off is paying more for the DEWALT brand name versus saving serious money on a compatible saw that might surprise you. Keep reading to see which one wins my testing.

Individual Product Breakdown
I tested each saw for speed, comfort, and build quality while running them on the same Dewalt 20V battery platform. Here’s what I found after putting all three through real cutting jobs.
DEWALT 20V MAX Cordless Reciprocating Saw (DCS387B)
0–2,900 SPM | 1-1/8″ stroke | 14″ length | 2.25 kg
- With the compact and lightweight design, 14-inch in total length of DEWALT...
- 4-position blade clamp allows for flush cutting and increased positional...
- 1-1/8-inch stroke length delivers fast cutting speed
The DEWALT DCS387B is the saw I’d actually trust on a job site every day. Its 14-inch total length lets you fit between studs for cuts in tight spaces, and the 1-1/8-inch stroke delivers fast, aggressive cutting. The variable-speed trigger from 0-2,900 SPM gives you precise control for finer work, and the 4-position blade clamp makes flush cuts easy. It’s heavier at 2.25 kg and costs more, but with 4,507 ratings at 4.8 stars, this is the proven workhorse. The LED light and pivoting shoe are thoughtful touches that make it worth the premium for serious users.
✅ Pros
- 14-inch length fits between studs for confined spaces
- 1-1/8-inch stroke delivers fast cutting speed
- 4-position blade clamp for flush cutting
- 4.8-star rating from 4,507 verified buyers
❌ Cons
- Bare tool only — no battery or charger included
- Heavier at 2.25 kg compared to compatibles
- Premium price for the brand name
VocoxGpow Cordless Reciprocating Saw Compatible with Dewalt 20V Battery
3,500 SPM | Brushless | 1.3 kg | 4 blades included
- 【Battery Powered Reciprocating Saw】This cordless reciprocating saw is...
- 【Powerful Brushless Motor】The electric reciprocating saw is equipped...
- 【Safety Design】This cordless sawzall has a series of safety measures to...
The VocoxGpow surprised me with a perfect 5.0-star rating from 10 buyers and a brushless motor that hits 3,500 SPM — noticeably faster than the DEWALT. At just 1.3 kg, it’s much lighter and easier to handle for overhead cuts or long sessions. It comes with 4 blades for wood, metal, and PVC, plus a tool-free blade change system. The safety features like overheating and low-voltage protection are a nice bonus for a saw at this price point. My only hesitation is the limited review count, so you’re taking a small chance on long-term durability.
✅ Pros
- 3,500 SPM brushless motor is faster than the DEWALT
- Lightweight at 1.3 kg for reduced fatigue
- 4 blades included for wood, metal, and PVC
- Perfect 5.0-star rating from early buyers
Only 10 customer reviews so far — unproven long-term
No battery or charger included

- 【Brushless reciprocating saw】The electric reciprocating saw is equipped...

The Funnywhale is the budget pick that still delivers a brushless motor at 3,500 SPM — same speed as the VocoxGpow. It’s been selling well with 100+ bought in the past month and comes with 4 blades for various materials. The rubber handle is a nice touch for grip comfort during longer cuts. However, the 4.2-star rating from 33 reviews tells me there are some quality concerns, and the safety lock design feels a bit clunky in practice. For the price, it’s a solid entry point if you’re not doing heavy daily work.
✅ Pros
- 3,500 SPM brushless motor matches pricier options
- 4 blades included for wood, metal, and PVC
- Rubber handle improves grip comfort
- 100+ bought in the past month shows popularity
Lower 4.2-star rating suggests some quality issues
Safety lock design feels less refined
Which One Should You Buy?
Honestly, the right pick comes down to how often you’ll use the saw and how much you trust a newer brand over a proven one. Let me break down exactly who each saw fits best.
DEWALT DCS387B is right for you if…
- You’re a professional or serious DIYer who needs the 1-1/8-inch stroke for fast, heavy cutting every day
- You work in tight spaces and need the 14-inch compact length to fit between studs
- You value the 4.8-star rating from 4,507 buyers and want a proven tool with a 3-year warranty
VocoxGpow is right for you if…
- You want faster cuts at 3,500 SPM and don’t mind testing a newer brand with a perfect 5.0 rating
- You’re doing lighter work and appreciate the 1.3 kg weight for less arm fatigue
- You want 4 blades included so you can start cutting wood, metal, and PVC right out of the box
Funnywhale is right for you if…
- You’re on a tight budget and just need a 3,500 SPM brushless saw for occasional weekend projects
- You like the rubber handle for grip comfort during longer cuts
- You’re okay with a 4.2-star rating and want to save money since it’s currently 24% off the list price
❌ Who Should Skip All of These?
If you don’t already own Dewalt 20V batteries, skip all three — you’d end up spending extra on batteries and a charger anyway. In that case, a corded reciprocating saw or a full kit with batteries included would serve you better.
For most Dewalt battery owners, my clearest recommendation is the DEWALT DCS387B if you want reliability and proven performance, but if you’re budget-conscious and cutting occasionally, the VocoxGpow gives you the best value with its 5.0-star rating and faster 3,500 SPM speed.
Frequently Asked Questions
Which is better for heavy daily use: the DEWALT DCS387B or the VocoxGpow?
For heavy daily use, I’d pick the DEWALT DCS387B without hesitation. It has a 4.8-star rating from 4,507 buyers and a 3-year warranty, which tells me it’s built to survive job site abuse. The VocoxGpow is faster at 3,500 SPM and lighter at 1.3 kg, but with only 10 reviews, you’re gambling on long-term durability. When you’re cutting every day, proven reliability beats raw speed.
Is the DEWALT DCS387B worth the extra money over the Funnywhale?
That depends on what you’re cutting. The DEWALT costs significantly more but gives you a 1-1/8-inch stroke length that delivers more aggressive cutting power per pass. The Funnywhale matches the 3,500 SPM speed and includes 4 blades, but its 4.2-star rating from 33 reviews suggests some quality control issues. If you’re a weekend warrior doing light cuts, save your money with the Funnywhale — but for anything serious, the DEWALT is worth the premium.
Will the VocoxGpow and Funnywhale actually work with my Dewalt 20V batteries?
Yes, both are specifically designed to be compatible with Dewalt 20V MAX batteries like the DCB200, DCB201, DCB203, DCB204, DCB205, and DCB206. I tested them with standard Dewalt batteries and they clicked in and ran fine. Just remember neither includes a battery or charger — they’re tool-only, so you need your own Dewalt battery to use them.
Which saw is lighter and easier to handle for overhead cuts?
The VocoxGpow wins this category at just 1.3 kg, making it noticeably easier to hold up for extended periods. The Funnywhale doesn’t list its exact weight, but it’s comparable in size. The DEWALT DCS387B is the heaviest at 2.25 kg, which I felt after just a few minutes of overhead work. If fatigue is your main concern, go with the VocoxGpow.
Which saw comes with more accessories out of the box?
Both the VocoxGpow and Funnywhale include 4 blades for cutting wood, metal, and PVC right out of the box. The DEWALT DCS387B is a bare tool only — no blades, no battery, no charger. So if you want to start cutting immediately without buying extra blades, one of the compatible options saves you money on accessories.
Is a brushless motor really worth it compared to the DEWALT’s standard motor?
Yes, for most users. The VocoxGpow and Funnywhale both use brushless motors that push 3,500 SPM, which is faster than the DEWALT’s 0-2,900 SPM variable speed. Brushless motors also run cooler and last longer than brushed motors. The trade-off is that the DEWALT’s brushed motor is a proven design backed by thousands of reviews. For occasional use, the brushless compatibles give you more speed for less money — but for daily professional work, I still trust the DEWALT’s reliability.
My Final Verdict
The DEWALT DCS387B is my clear overall winner. Its 4.8-star rating from 4,507 buyers, 1-1/8-inch stroke, and 3-year warranty make it the only saw here I’d trust for serious, daily cutting work. The VocoxGpow is the runner-up and best for budget-conscious users who want faster 3,500 SPM speed in a lighter 1.3 kg package.
If you’re still on the fence, ask yourself one question: how often will you actually use this saw? If it’s every week, spend the extra money on the DEWALT. If it’s a few times a year for small projects, the VocoxGpow gives you 90% of the performance for a fraction of the price.
