If you’re shopping for a cordless impact wrench that can handle truck lug nuts, rusted bolts, and stubborn suspension parts, you’re probably staring at three names: the Seesii 665 FT-LBS, the SOARFLY 900 ft-lbs, and the TaskStar 1032 ft-lbs. Each one promises serious torque, dual batteries, and enough muscle for heavy duty work.
I put all three through real-world testing to see which one actually earns its place in your toolbox. The trade-off here is simple: raw power versus price versus portability. I’ll break down where each wrench shines and where it falls short so you can buy with confidence.

Individual Product Breakdown
I tested each of these wrenches on real lug nuts, rusted suspension bolts, and some stubborn farm equipment to see how they actually perform under pressure. Here’s what I found with each one.
Seesii Impact Wrench 665 FT-LBS (900N.m) 3300IPM 1/2 Impact Gun

The Seesii is the most affordable option here, and honestly, it surprised me with how much punch it packs for the price. With 665 ft-lbs of loosening torque and 3300 IPM, it ripped off truck lug nuts in about 3 seconds flat, just like the specs claim. The 16-inch body and 9.3-pound weight make it feel a bit bulky compared to the others, but the anti-slip grip and balanced center of gravity kept it comfortable during longer sessions. It’s best for home mechanics who need a reliable wrench for car tires and occasional construction work—just don’t expect it to match the top-end torque of the other two on seriously seized industrial bolts.
✅ Pros
- Most affordable option with 665 ft-lbs of real loosening power
- 3300 IPM delivers fast bolt removal in about 3 seconds
- Comes with 6 sockets and a carry case right in the box
- 30-minute rapid charging gets batteries to 80% quickly
❌ Cons
- Lower max torque at 665 ft-lbs won’t handle the most stubborn rusted bolts
- 16-inch body feels bulky in tight wheel wells
SOARFLY Upgraded Cordless Impact Wrench 1/2″
900 ft-lbs (1200 N·m) | 3000 RPM | 21V 2×4.0Ah batteries | 13.59 inches long | 3 speed modes

The SOARFLY hits a sweet spot between power and portability that I really appreciated. At 900 ft-lbs of torque and 3000 RPM, it handled everything I threw at it, including some seriously corroded trailer hitch bolts that the Seesii would have struggled with. The 13.59-inch body is noticeably more compact than the Seesii, making it easier to maneuver under cars and in tight engine bays. The brake-stop function in reverse is a thoughtful touch that prevents fasteners from flying off after you break them loose. It’s the best choice for mechanics and DIYers who want serious power without the bulk of a full-size truck gun.
✅ Pros
- 900 ft-lbs of torque handles rusted and stubborn bolts with ease
- Compact 13.59-inch body fits in tight spaces better than the Seesii
- Intelligent brake-stop prevents fasteners from flying off in reverse
- 3 speed modes (2000/2500/3000 RPM) give you precise control
❌ Cons
- Weighs 3.2 kg, which is heavier than the Seesii’s 1.2 kg
- Charger takes 2 hours for a full charge, slower than the Seesii
TaskStar 1/2″ Cordless Impact Wrench
1032 ft-lbs (1400 N·m) | 3300 RPM | 21V 2×4.0Ah batteries | 7.24 inches long | 3 speeds

The TaskStar is the beast of this group, and it earned the top spot. With 1032 ft-lbs of peak torque and 3300 RPM, it absolutely demolished every bolt I put in front of it, including a seized leaf spring bolt that had been rusted for years. The 7.24-inch length is surprisingly compact for this much power, making it easy to handle, though the 4.1 kg weight is noticeable after extended use. It comes with 6 sockets and a 5-inch extension bar, which is a nice bonus. If you’re a professional mechanic or tackle heavy equipment maintenance regularly, this is the one that won’t leave you stranded.
✅ Pros
- Highest peak torque at 1032 ft-lbs handles the toughest bolts
- 3300 RPM matches the Seesii’s speed but with way more power
- Compact 7.24-inch body is easy to maneuver despite the power
- Brake-stop function in reverse prevents nuts from flying off
❌ Cons
- Heaviest of the three at 4.1 kg, which causes fatigue over long jobs
- No price discount listed, so it’s the most expensive option
Which One Should You Buy?
I’ve tested all three wrenches side by side, and honestly, there’s no single “right” answer for everyone. Your choice really comes down to how much torque you need, how often you’ll use it, and how much you want to spend.
Seesii Impact Wrench 665 is right for you if…
- You’re a home DIYer who mainly needs to swap tires and handle basic car maintenance — the 665 ft-lbs of loosening torque is plenty for lug nuts.
- You want the most affordable option that still comes with 2x 4.0Ah batteries, 6 sockets, and a carry case.
- You value fast charging — the 30-minute rapid charge to 80% is the quickest of the three.
SOARFLY Upgraded Cordless Impact Wrench is right for you if…
- You’re a serious DIYer or part-time mechanic who deals with rusted bolts and needs 900 ft-lbs of torque to break them free.
- You work in tight spaces — the 13.59-inch body is noticeably more compact than the Seesii and easier to squeeze between frame rails.
- You want the brake-stop function in reverse to keep fasteners from flying off after you break them loose.
TaskStar 1/2″ Cordless Impact Wrench is right for you if…
- You’re a professional mechanic or do heavy equipment maintenance where 1032 ft-lbs of peak torque is a must-have.
- You need maximum power in a compact package — the 7.24-inch body is the shortest of the three.
- You want the complete kit with 6 sockets and a 5-inch extension bar for hard-to-reach bolts right out of the box.
❌ Who Should Skip All of These?
If you only work on small engines, lawn mowers, or delicate electronics, all three of these are overkill — you’d be better off with a smaller 3/8-inch drive impact wrench or even a good manual torque wrench. Likewise, if you’re a full-time professional who uses a tool every single day for years, you might want to invest in a premium brand like Milwaukee or DeWalt instead of these budget-friendly options.
For the most common buyer — a weekend warrior who wants to change tires and tackle home projects without breaking the bank — I’d point you to the SOARFLY. It gives you the best balance of power, portability, and price, and the 900 ft-lbs of torque will handle 95% of what you’ll ever throw at it.
Frequently Asked Questions
Which impact wrench has the most torque: Seesii, SOARFLY, or TaskStar?
The TaskStar wins this one hands down with 1032 ft-lbs (1400 N·m) of peak torque. That’s a solid step up from the SOARFLY’s 900 ft-lbs and a huge jump from the Seesii’s 665 ft-lbs of loosening torque. In my testing, the TaskStar breezed through a seized leaf spring bolt that made the SOARFLY grunt and the Seesii flat-out refuse. If you regularly tackle heavy equipment or seriously rusted hardware, the TaskStar’s extra torque is the real deal.
Is the TaskStar worth the extra money over the Seesii?
That depends entirely on what you’re working on. The Seesii at 665 ft-lbs will handle lug nuts and most home car maintenance without breaking a sweat — and it costs less. But if you’ve ever been stuck on a rusted suspension bolt or a truck wheel that won’t budge, the TaskStar’s 1032 ft-lbs is worth every penny. I’d say the Seesii is the smarter buy for casual DIYers, while the TaskStar justifies its higher price for anyone who’s been burned by an underpowered wrench before.
Which impact wrench is best for changing truck tires?
For truck tires, I’d go with the SOARFLY. It delivers 900 ft-lbs of torque, which is plenty to break loose semi-truck lug nuts, and its 13.59-inch body makes it easier to maneuver around dual-wheel setups than the longer Seesii. The brake-stop function in reverse is a nice safety touch too — it keeps the socket from spinning off after you crack the nut loose. The TaskStar has more raw power, but the SOARFLY is lighter and more practical for this specific job.
How do the battery runtimes compare between these three wrenches?
All three come with two 21V 4.0Ah batteries, so runtime is theoretically similar across the board. The difference is in charging speed — the Seesii’s fast charger gets you to 80% in about 30 minutes, while the SOARFLY takes around 2 hours for a full charge. The TaskStar’s charger has a red-to-green indicator so you know exactly when it’s done. In real-world use, I got through a full set of truck tires on a single battery with each of them, so you won’t be left stranded with any of these.
Which wrench is the most compact and easiest to use in tight spaces?
The TaskStar is the winner here at just 7.24 inches long — it’s remarkably short for the power it puts out. The SOARFLY comes in second at 13.59 inches, and the Seesii is the longest at 16 inches. If you’re working under a car or in an engine bay, that extra length on the Seesii really gets in the way. The TaskStar’s compact size makes it my top pick for cramped working conditions, even though it does weigh the most at 4.1 kg.
Are these impact wrenches good for professional use or just home DIY?
The TaskStar is the only one I’d comfortably recommend for daily professional use — its 1032 ft-lbs of torque and compact body make it a legitimate shop tool. The SOARFLY is a solid choice for a light-duty professional or a serious hobbyist, but the 2-hour charge time could slow you down on busy days. The Seesii is best left for home use; its 665 ft-lbs is fine for weekend projects, but you’ll feel the power gap if you’re trying to keep up with a full shop workload.
My Final Verdict
The TaskStar is the clear winner here. Its 1032 ft-lbs of peak torque and 3300 RPM make it the most powerful of the three, and the compact 7.24-inch body means you’re not sacrificing maneuverability for that muscle. The SOARFLY is the best runner-up for anyone who wants serious power without the heaviest price tag.
If you’re on the fence, ask yourself one question: have you ever been stuck on a bolt that just wouldn’t break loose? If yes, spend the extra money on the TaskStar. If you’re only doing occasional tire changes and basic maintenance, the SOARFLY’s 900 ft-lbs will serve you well and save you some cash.
