Black & Decker LST136 vs EGO Power+ ST1502

This lightweight trimmer is extremely easy to use: just pull it out of the shed, check if the string is loaded, attach the battery, and you are good to go without any power cords, oil mixing, or spark plug cleaning.

Contrarily to what happens with gas string trimmers, there is no need to worry about oil, spark plugs, engine wear, or keeping extra gas.

With a quick turn of the shaft, the trimmer can quickly become an edger, complete with height guard to keep your edges even. Additionally, a built-in guide helps to keep the edge straight and even. It flips up out of the way when the unit is in trimming mode. Versatility like this eliminates the need to buy another tool just for edging.

Black & Decker provides spare parts and plans for this trimmer, so you can just order a new part and replace it yourself.

Since it is a single-line trimmer it is easier to wind in the line without any unnecessary tangles that can happen with dual line trimmers.

The line feeds itself, depending on the resistance detected, as you trim along.

The trimmer has a 13" cutting path, so you don’t have to swing it around as much as with trimmers with a narrower path.

The trimmer has six different power settings, allowing the operator to adjust the speed that's best suited to the current scenario.

The LED indicator on the battery tells you how much power is left, so you don’t have to do any guessing.

You can use batteries from other Black & Decker tools that use 40V lithium-ion elements, allowing you to swap batteries between tools whenever necessary.

Because of the adjustable shaft height, you can optimize the trimmer to a comfortable level, avoiding unnecessary back pain. However, due to its short length, it may no be very suited for tall users.

Weighing under 8 pounds, it can even be used by teenagers and seniors without risk of back pain.

The trimmer has a 56 V powerful brushless motor in combination with a 0.095" thick string. The motor is powerful enough to easily cut down tall grass and even very thick weeds that would be impossible to deal with using less powerful weed whackers.

The included 2.5 Ah battery lasts around 40 minutes, but it is possible to install a 7.5 Ah battery that has the power to operate this trimmer for two hours non-stop. Just keep in mind that the bigger the battery, the heavier and more expensive it is.

This trimmer has a solid and professional feel, as it is built with high-quality aluminum and sturdy, rubber-coated plastics. The construction does not feel loose or wobbly.
