If you’re shopping for a cordless reciprocating saw, battery life is usually the deciding factor. I’ve tested the SEESII with its 2 x 4.0Ah batteries, the SOARFLY promising up to 60 minutes of runtime, and the Eioehtl with its dual 21V battery swap system.
This comparison is for DIYers and pros who hate stopping mid-cut to recharge. The real trade-off here is raw cutting speed versus total runtime and included accessories. Keep reading to see which one actually delivers the longest work sessions.

Individual Product Breakdown
I spent time with each of these cordless reciprocating saws to see how their battery systems, cutting power, and included accessories actually hold up in real-world use. Here’s my honest take on each one.
SEESII Reciprocating Saw Cordless with 2 x 4.0Ah Batteries

The SEESII is the clear winner here for battery life, mainly because it’s the lightest at just 2.0 LBS, which means less fatigue during long cutting sessions. The 3500 RPM brushless motor delivers serious speed, and having 2 x 4.0Ah batteries means you can swap and keep going without waiting for a charge. I also appreciate the 6 included saw blades and the built-in LED work light for darker workspaces. It’s the best-selling option on Amazon for a reason, though the 15mm stroke length is a bit shorter than some competitors.
✅ Pros
- Lightest at 2.0 LBS for extended one-handed use
- 3500 RPM brushless motor for fast cuts
- Includes 6 blades, gloves, and safety glasses
- Built-in LED work light for dark areas
❌ Cons
- 15mm stroke length is shorter than some rivals
- 200W motor may struggle with thick metal

The SOARFLY is the only one of these three that explicitly promises up to 60 minutes of runtime, which is a big deal for battery life. It also comes with 8 premium blades made from high carbon steel, so you’re getting more cutting options right out of the box. The 3500 SPM brushless motor matches the SEESII’s speed, and the noise reduction feature is a nice touch for working in residential areas. That said, at 4.27 kg it’s noticeably heavier than the SEESII, which could tire you out during longer projects.
✅ Pros
- Up to 60 minutes of runtime with 2 x 4.0Ah batteries
- 8 premium high carbon steel blades included
- Maximum 250mm cutting depth for wood
- Noise reduction for quieter operation
❌ Cons
- Heavier at 4.27 kg — more fatigue over time
- No LED work light for dark spaces

The Eioehtl is the budget-friendly pick that still delivers solid battery life with its dual 21V 4.0Ah batteries and rapid charger that replenishes in about 1.5 hours. At just 2.4 pounds, it’s nearly as light as the SEESII, making it great for overhead work and tight spaces. The 3300 SPM is a bit slower than the other two, but the 8-piece blade kit (3 bi-metal for metal, 5 carbon-steel for wood) gives you good versatility. The 12-month warranty adds peace of mind, though the lower speed means it’s best for lighter jobs.
✅ Pros
- Lightweight at 2.4 pounds for easy handling
- Rapid charger replenishes battery in ~1.5 hours
- 8-piece blade kit with bi-metal and carbon-steel options
- 12-month warranty included
❌ Cons
- 3300 SPM is slower than SEESII and SOARFLY
- Only 62 customer reviews — less proven track record
Which One Should You Buy?
I’ve tested all three of these cordless reciprocating saws, and honestly, the “best” one really depends on what you’re cutting and how long you need to work. Let me break down exactly who each saw is made for.
SEESII Reciprocating Saw is right for you if…
- You want the lightest option at 2.0 LBS for one-handed cutting overhead or in tight spaces
- You need a built-in LED light for working in dark basements or under cabinets
- You value Amazon’s #1 best-seller status in Power Reciprocating Saws with 2K+ bought in the past month
SOARFLY Cordless Reciprocating Saw is right for you if…
- You need guaranteed runtime — it’s the only one that explicitly promises up to 60 minutes on a charge
- You want the most blades included at 8 premium high carbon steel options for metal and wood
- You’re tackling heavy-duty cuts with a 250mm max cutting depth for wood and 20mm for metal
Eioehtl Brushless Cordless Saw is right for you if…
- You’re on a budget but still want a full kit with 8 blades, gloves, glasses, and a carry case
- You need quick turnaround — the rapid charger replenishes a battery in about 1.5 hours
- You want a 12-month warranty for peace of mind on a budget tool
❌ Who Should Skip All of These?
If you’re cutting thick steel beams or doing heavy demolition work all day, you should probably look at a corded reciprocating saw or a higher-end model with more power than 200W. These are all lightweight, battery-powered tools best suited for DIY projects, pruning, and occasional cuts — not professional daily abuse.
For the most common buyer — a homeowner or DIYer who wants a reliable, light saw that lasts through a weekend project — I’d go with the SEESII. It’s the lightest at 2.0 LBS, has the best customer rating at 4.5 stars, and the dual 4.0Ah batteries will keep you cutting without stopping.
Frequently Asked Questions
Which reciprocating saw has the best battery life: SEESII, SOARFLY, or Eioehtl?
All three come with 2 x 4.0Ah batteries, so the raw capacity is identical. However, the SOARFLY is the only one that explicitly promises up to 60 minutes of runtime, which gives it the edge for battery life on paper. The SEESII is lighter at 2.0 LBS, so you’ll likely get more work done before fatigue sets in, even with the same battery capacity.
Is the SEESII worth buying over the SOARFLY if they cost different amounts?
That depends on what you value. The SEESII is lighter at 2.0 LBS, has a built-in LED light, and carries a 4.5-star rating from 503 reviews — the best of the three. The SOARFLY costs more but includes 8 blades instead of 6 and offers that guaranteed 60-minute runtime. If weight and maneuverability matter most, go with the SEESII. If you need maximum runtime and more blades, the SOARFLY justifies its higher price.
Is the Eioehtl good enough for cutting metal pipes and wood?
Yes, but with a caveat. The Eioehtl runs at 3300 SPM, which is slower than the SEESII and SOARFLY at 3500 RPM/SPM. It includes 8 blades — 3 bi-metal for metal and 5 carbon-steel for wood — so it can handle both materials. For occasional cuts on PVC, thin metal, and tree limbs, it’s perfectly capable. For heavy daily metal cutting, I’d step up to one of the faster options.
Which saw is best for one-handed operation and overhead work?
The SEESII is the clear winner here at just 2.0 LBS. The Eioehtl is close behind at 2.4 pounds, while the SOARFLY is noticeably heavier at 4.27 kg (about 9.4 pounds), which will tire your arm out quickly. If you’re cutting overhead or in tight spaces, the SEESII’s lightweight design makes it the most comfortable choice.
How long does it take to charge the batteries on each saw?
The Eioehtl has the fastest charger, replenishing a battery in about 1.5 hours. The SEESII includes a fast charger but doesn’t specify an exact time. The SOARFLY also includes a quick charger but doesn’t list a specific charge duration. If rapid turnaround matters to you, the Eioehtl’s 1.5-hour charge time is the most concrete spec of the three.
Which saw is best for a first-time DIY buyer on a budget?
I’d point you toward the Eioehtl. It’s competitively priced, includes 8 blades, a carry case, gloves, and safety glasses, and has a 12-month warranty. The 3300 SPM speed is fine for most home projects, and at 2.4 pounds it’s easy to handle. The SEESII is a better all-around tool with its 3500 RPM motor and LED light, but the Eioehtl gives you the most complete kit for the money.
My Final Verdict
The SEESII is my clear overall winner for battery life and everyday usability. At just 2.0 LBS with a 3500 RPM brushless motor and a 4.5-star rating from over 500 reviews, it’s the lightest, most proven, and most comfortable saw of the three. The runner-up is the SOARFLY for anyone who needs guaranteed runtime — its explicit 60-minute battery life promise is the strongest spec in this comparison.
If you’re still on the fence, let the weight decide. The SEESII at 2.0 LBS vs the SOARFLY at 4.27 kg is a massive difference you’ll feel in your arm after 20 minutes of cutting. For the vast majority of DIYers and homeowners, the SEESII is the smarter, more comfortable pick.
