I remember the Sunday afternoons spent wrestling with my old corded hedge trimmer. It was a constant, frustrating dance: trim a section, drag the extension lead, untangle it from the rose bushes, and always, always keep one eye on that bright orange cable, terrified of the day I’d inevitably slice through it. The tool was heavy, the vibrations numbed my hands, and the sheer hassle of it all turned a satisfying garden task into a dreaded chore. For many homeowners, this is the reality of hedge maintenance—a job dictated by the length of a cord and the strength of your back. This is precisely the problem the cordless revolution promises to solve, and the Terratek 20V Cordless Hedge Trimmer 51cm positions itself as an accessible, powerful solution for those ready to finally cut the cord. It promises freedom, ease of use, and enough power to tame the garden, all without the premium price tag. But does it deliver?

What to Consider Before Buying a Cordless Hedge Trimmer
A cordless hedge trimmer is more than just a garden tool; it’s a key solution for reclaiming your time and making garden upkeep safer and more enjoyable. By eliminating the power cable, you gain unparalleled freedom of movement, allowing you to tackle hedges at the far end of the garden, sculpt awkward shapes, and work more efficiently without the constant risk of tripping or cutting the cord. The primary benefits are speed, safety, and convenience, transforming hedge trimming from a logistical puzzle into a straightforward task. When we first got our hands on the Terratek 20V Cordless Hedge Trimmer 51cm, these were the core promises we were eager to test.
The ideal customer for this type of product is the home gardener with small to medium-sized hedges who values convenience and ease of use. If you’re tired of extension cords, have hedges that aren’t excessively old or woody, and perform maintenance trims a few times a year, a cordless model like this is a perfect fit. It’s especially suitable for those who may struggle with heavier, petrol-powered models. However, it might not be the right choice for professional landscapers who need all-day runtime and the ability to chew through ancient, thick branches consistently. For those users, a high-end professional model or a powerful petrol trimmer might still be necessary.
Before investing, consider these crucial points in detail:
- Blade Length & Cutting Capacity: The blade length determines how much of the hedge you can cut in a single pass. A longer blade, like the 51cm on this Terratek model, is more efficient for long, straight hedges. Cutting capacity, measured in millimetres, tells you the maximum branch thickness the trimmer can handle. The Terratek’s 15mm capacity is standard for domestic use, suitable for newer growth and maintenance, but may struggle with thick, woody stems.
- Battery System & Runtime: This is the heart of any cordless tool. Look at the voltage (V) for power and the amp-hours (Ah) for runtime. A key advantage here is that the Terratek 20V Cordless Hedge Trimmer 51cm comes with two batteries and a fast charger. This is a game-changer, as it allows for continuous work—one battery charges while you use the other. A claimed runtime of up to 40 minutes per battery is ample for most domestic jobs.
- Weight & Ergonomics: A hedge trimmer is held at chest or shoulder height for extended periods, so weight is critical. At just 2.5kg, this model is impressively lightweight, reducing user fatigue. Good ergonomics also include a comfortable grip, good balance, and safety features like a two-stage trigger and a hand guard to protect you from the blades.
- Materials & Durability: The body is typically made of durable plastic to keep the weight down, while the blades should be high-quality steel. While stainless steel blades are specified, some user feedback suggests they may wear on tougher materials like holly. For most common hedges like privet or laurel, they should hold up well with proper care, which includes cleaning and oiling after each use.
Understanding these factors will ensure you choose a tool that not only meets the demands of your garden but also makes the work a pleasure rather than a pain.

First Impressions: Unboxing the Terratek 20V Cordless Hedge Trimmer 51cm
Pulling the Terratek 20V Cordless Hedge Trimmer 51cm from its box, the first thing we noticed was its weight—or rather, the lack of it. At 2.5kg, it feels remarkably light and manageable, a stark contrast to the bulky corded and petrol models of old. The assembly is virtually non-existent; you simply attach the safety guard with a couple of screws, and you’re ready to go. The bright orange and grey plastic housing feels solid enough for domestic use, and the handles are ergonomically shaped for a comfortable grip.
The real value, however, becomes apparent when you see the complete package. Inside the box, you don’t just get the trimmer; you get two 20V batteries and a 1-hour fast charger. This is a significant advantage over many competitors, where batteries and chargers are often sold separately, adding considerable hidden costs. Having a second battery ready to go eliminates runtime anxiety. While some online users have reported issues with items arriving damaged or with cosmetic defects, our review unit was in perfect condition, suggesting that while quality control could be a concern for some, a good unit delivers an excellent out-of-the-box experience. The immediate impression is one of outstanding value for money.
What We Like
- Excellent value with two 20V batteries and a fast charger included
- Impressively lightweight at 2.5kg, reducing user fatigue
- Generous 51cm blade length for efficient cutting
- Surprising cutting power for a budget-friendly model
- Cordless design offers complete freedom and enhanced safety
Limitations
- Reports of quality control issues (damaged items, faulty chargers)
- Blade durability can be a concern on very tough, woody hedges
A Deep Dive into the Terratek’s On-the-Job Performance
An impressive feature list is one thing, but the true test of any garden tool is how it performs out on the lawn, covered in clippings and pushed to its limits. We put the Terratek 20V Cordless Hedge Trimmer 51cm through its paces on a variety of common garden hedges to see if its real-world performance matches its on-paper promise.
Cutting Power and Blade Performance
Scepticism is natural when it comes to budget-friendly cordless tools. Often, “cordless” can be a synonym for “gutless”. We were, therefore, thoroughly impressed with the cutting power of this machine. We started with a long run of privet hedge that was overdue for a trim. The 51cm stainless steel blades sliced through the green growth cleanly and effortlessly. The 1100 RPM speed is sufficient to provide a neat finish without tearing the leaves. The generous blade length made quick work of the flat top and sides, significantly speeding up the job compared to a shorter trimmer.
To really test its mettle, we moved on to a tougher, more established laurel hedge. This is where many budget trimmers begin to struggle. The Terratek, however, handled it with surprising authority. It chewed through branches up to about 10-12mm thick without hesitation. We found it could handle the occasional 15mm branch, as specified, though it required a slower, more deliberate approach. This performance confirms the findings of one user who was “bowled over” by the power, noting it cut through growth “about the size of my little finger width with ease.” However, it’s important to set realistic expectations. We also noted the feedback from a user who found the blades wore quickly on a tough holly hedge. Based on our tests, we’d conclude that this trimmer is a champion for maintenance and taming common hedges but is not the ideal tool for aggressive reclamation of old, gnarled, and woody hedges like holly or pyracantha. For its intended purpose, the cutting performance is a significant highlight.
The Two-Battery System: A Cordless Game-Changer
The single greatest feature of the Terratek 20V Cordless Hedge Trimmer 51cm package is, without a doubt, the inclusion of two batteries and a fast charger. This elevates the tool from being merely convenient to being genuinely practical for substantial jobs. Each battery provided us with a consistent runtime of around 35-40 minutes of near-continuous trimming. This was more than enough to complete one long side of a 25-meter hedge.
The magic happens with the 1-hour fast charger. As soon as we started using the first battery, we put the second on to charge. By the time the first battery was depleted, the second was fully charged and ready to swap in. This cycle allows for virtually uninterrupted work, eliminating the biggest drawback of many single-battery cordless systems where you have to stop and wait for a recharge. This was echoed perfectly by a user who stated, “The second battery had charged before the first has run out.” This system provides the endurance needed to tackle larger gardens in one session. While we must acknowledge that a minority of users have reported issues with faulty chargers, our supplied unit worked flawlessly, bringing batteries from empty to full in just under an hour. This dual-battery setup is what makes this trimmer not just a tool for quick touch-ups, but a serious contender for all your hedge-trimming tasks.
Ergonomics, Handling, and Safety in Use
Power is useless if a tool is too heavy or awkward to wield effectively. This is where the Terratek truly shines. Weighing only 2.5kg, it is a pleasure to use, even for extended periods. We found that trimming the top of a 6-foot hedge, which requires holding the tool at shoulder height, was far less fatiguing than with heavier models. The balance is excellent, with the battery pack acting as a neat counterweight to the blade, preventing the nose-heavy feeling that can plague other trimmers.
This lightweight design makes it incredibly accessible. We were particularly struck by the feedback from a 57-year-old user with joint problems who found it was the only trimmer she could comfortably manage. This speaks volumes about its user-friendly design. Safety is also well-addressed. The two-stage safety trigger system requires you to depress a switch on the front loop handle and pull the main trigger simultaneously, preventing any accidental start-ups. The moment you release the trigger, the blades stop instantly. This, combined with the sturdy hand guard that separates your forward hand from the cutting blades, provides confidence and peace of mind during operation. For anyone who has felt intimidated by larger, more cumbersome garden machinery, the lightweight and safe handling of the Terratek is a major selling point.
What Other Users Are Saying
Across the board, the sentiment from users is largely positive, with most being genuinely surprised by the performance offered at this price point. Many, like us, highlight the incredible value of receiving two batteries and a fast charger in the box. One owner commented, “This product is amazing, for the price most definitely,” after it cut through thick ivy with ease. The freedom from cables is a recurring theme, with users celebrating the ability to work anywhere in the garden without hassle.
However, the feedback isn’t universally glowing, and it’s important to note the criticisms. The most common complaints revolve around quality control. A number of users reported receiving units that were damaged in transit, with broken safety guards being a specific issue. Others have experienced technical failures, from chargers that won’t charge the batteries to one instance where a trimmer reportedly “stopped working after 5 minutes with smoke coming out.” While these appear to be minority cases, they do suggest a potential inconsistency in manufacturing or shipping that prospective buyers should be aware of. The 2-year guarantee offers some reassurance, but the initial experience can be disappointing for those who receive a faulty unit.
How Does the Terratek Compare to the Alternatives?
The Terratek 20V Cordless Hedge Trimmer 51cm carves out a strong niche in the budget-friendly category, but how does it fare against other popular options? We’ve looked at three key competitors to help you decide.
1. Einhell GE-CH 1846 Li Cordless Hedge Trimmer Kit
- Suitable for the Einhell power x-change battery system
- Supplied with 2 Ah battery and fast charger
The Einhell GE-CH 1846 Li is a strong contender from a well-respected brand. Its main differentiator is the blade quality, featuring laser-cut and diamond-ground steel blades that promise superior sharpness and longevity compared to the Terratek’s standard stainless steel. It operates on Einhell’s Power X-Change 18V battery system, which is a bonus if you already own other Einhell tools. However, its blade is shorter at 46cm, making it slightly less efficient on long, straight hedges. While it comes as a complete kit, the Terratek’s package with two batteries and a slightly higher 20V power system gives it the edge in terms of sheer value and continuous runtime for new buyers.
2. DEWALT DCM563PB-XJ 18V Cordless Hedge Trimmer
- 55cm dual-action laser-cut blades with 19mm cutting gap and hardened steel for longer life and lasting sharpness
- Extended runtime: up to 75min trimming per charge on a 5.0Ah battery (not included)
The DEWALT hedge trimmer represents a significant step up in terms of build quality, durability, and performance. It’s aimed at serious DIYers and professionals who demand robust, reliable tools. Its 55cm hardened steel blade and powerful motor will handle tougher, woodier growth more effectively than the Terratek. The crucial thing to note is that this is sold as a “bare unit”—the price does not include a battery or charger. If you’re already invested in the DEWALT 18V XR platform, it’s an excellent choice. If not, the total cost of the trimmer, batteries, and charger will be several times that of the Terratek, placing it in a completely different price bracket.
3. Einhell GE-HC 18 Li T Pole Hedge Trimmer
- The simple tree and hedge care thanks to the 2-in-1 hedge trimmer and power saw attachment and high-quality components with powerful Power X-Change battery power
- Versatile adjustment possibilities with telescopic arm, 7-fold tiltable motor head, 90° swivelling attachment for easy horizontal cut and adjustable handles
This Einhell tool isn’t a direct competitor but rather a solution for a different problem: tall hedges. It’s a multifunctional pole tool that can be used as a long-reach hedge trimmer or a mini chainsaw. If your primary challenge is safely trimming the tops of very tall conifers or hedges without a ladder, this is the specialised tool you need. It offers fantastic reach that the standard Terratek cannot match. However, for general-purpose trimming at normal heights, its weight and length would be cumbersome. Like the DEWALT, it’s typically sold as a bare unit, requiring a separate purchase of a battery and charger from the Power X-Change family.
Our Final Verdict on the Terratek 20V Cordless Hedge Trimmer 51cm
After extensive testing and careful consideration of user feedback, our verdict is clear: the Terratek 20V Cordless Hedge Trimmer 51cm offers exceptional, almost unbeatable, value for the average UK homeowner. It successfully delivers on the promise of cordless freedom, making hedge trimming faster, safer, and far less of a chore. Its lightweight design is a massive benefit, opening up garden maintenance to a wider range of users, while its cutting power is more than sufficient for the vast majority of domestic hedges.
The masterstroke of this package is the inclusion of two batteries and a fast charger, which effectively eliminates runtime anxiety and allows you to tackle substantial jobs in a single go. While it may not have the premium build quality of a DEWALT or the specialised blades of an Einhell, it isn’t trying to compete in that arena. It is designed to be an affordable, practical, and effective tool for the masses. The potential for quality control issues is a valid concern, but with a 2-year guarantee for peace of mind, it’s a calculated risk. If you’re looking to ditch your old corded trimmer and embrace the convenience of cordless without breaking the bank, this is a fantastic choice. We can confidently recommend checking the latest price and seeing if it’s the right fit for your garden today.
