Even if the lawn had not been cut in a while, you will probably be pleased by the reliability and efficiency of this gasless powered trimmer. In fact, it has a similar run time as a regular lawnmower that has a full gas tank.

While CORE is not as popular as the other leading brands in the sector, their portable outdoor devices are very well designed and feature a proprietary motor build technology.

The result is that the motor used in this trimmer can generate high torque movement within a small area as well as being very quiet and free of emissions. Additionally, the high-energy power cell guarantees extended running times, all in an ergonomic and lightweight package.

The CORE GasLess Power CGT400 CGTSD Gasless Powered Trimmer is a remarkable unit that makes quick and easy work of all your grass maintenance needs. It is perfectly balanced and its quick trigger start is as effortless to use as simply turning on your light. The dual line head helps the unit work efficiently without the issues of snagging, which is common with most electric trimmers.

The high capacity Lithium-ion cell used in this device may not have come with a level indicator, but that does not deter from its ability to last for over one hour. The overall run time is simply outstanding for a cordless trimmer, enabling you to cut those pesky weeds without the need to wait in between battery charges. Actually, the battery performance and how quickly it charges up are some of the best features of this gasless trimmer.

Powering the CORE CGT400 CGTSD trimmer is a very powerful motor based on a proprietary design that allows for similar torque outputs as regular 2-cycle gas engines. Even on a slow setting, this gasless trimmer has enough torque to make fast work thick weeds and grass. Since you can adjust the torque and power, you gain from more flexibility in terms of high power output as well as ability to lower the RPM when you want to extend the run time.

Besides producing a lot more torque than similar cordless trimmers, the motor in this unit has been designed to be ultra-quiet and lightweight. This translates to a less strenuous cutting session as it can be lifted easily and maneuvered around hard to reach areas. Combining the nice weight distribution with its 11 pounds weight means that your trimming tasks will not be hard or exhausting on your body.

There is a key tradeoff for the long lasting battery that is worth mentioning, which is that it takes quite a while to recharge. You will need to wait for 3 hours in order to get a full recharge of the power cell. However, future models of the unit are expected to come with a quick charging feature, though that remains to be seen for now.

This CORE GasLess Power CGT400 CGTSD clearly has a lot to offer in the cordless trimmer market space, especially with its unique innovative technologies.

Its gasless and cordless design ensure that cutting work is smell-free and hassle-free as there are no power cords or gas needed. Additionally, with its remarkably high power output, this American made cordless trimmer is a great choice.


BLACK+DECKER LST136W Cordless String Trimmer is a nice alternative to this CORE CGT400 due to several reasons. For one, BLACK+DECKER is one of the most widely trusted and well-known brands, so you definitely expect great quality products. The LST136W does not disappoint in that regard as it feels very robust and has a great balance despite the battery placement on the handle.

The controls are excellent as well since they can even be used with gloves. However, when it comes to performance, the CORE CGT400 is an outright winner with higher torque output and longer run time. In addition, the LST136W uses a narrower cutting diameter as part of its design in order to be able to maximize its power output.

The other notable competitor of this CORE gasless model is the GreenWorks 21362 G-MAX 40V 14-Inch Cordless String Trimmer.  This one ships with a high capacity 4Ah batter and charger as part of a kit. It has sufficient power for daily cutting tasks and it can cut heavier weeds on the high power setting. The only major concern is that the speed builds up very slowly after switching it on as compared to the CORE CGT400 gasless trimmer.


There is no doubt that the CORE GasLess Power CGT400 CGTSD Gasless Powered Trimmer, 3 Hour Charger, 1 Power Cell is a great machine. It performs like a professional trimmer due to its use of highly innovative motor and battery technologies.

It starts quickly, runs with minimal vibration and sound, and will cut through nearly anything. No one who buys this unit will be let down by its performance.
