Black and Decker LSTE525 Review – 20 V String Trimmer

Why would you want to spend a lot of money on a trimmer and a wheeled edger for your lawn, when you can get two tools in one with the Black and Decker LSTE525 20 Volt MAX lithium easy-feed string trimmer edger?

You can get a lot more done with this simply awesome tool, and it comes with two batteries so if you run out of charge, you can pop the other in and keep on working.

A lot of other trimmers only come with one battery, and in some cases, you have to buy the battery separately. To have two 20 volt batteries included is really quite rare, and quite impressive.

You can spend a lot of money on a weed trimmer and an edger, but there is no reason to waste money unnecessarily when you can get a single tool that does both jobs.

This trimmer easily converts to an edger. It is designed to trim overgrowth after you mow, and it is great for taking care of edging along borders, flower beds, and even sidewalks.

It won’t be long before you have the neatest yard on the block once you start using the LSTE525.

Features of This Black and Decker Cordless Weed Eater

Obviously, one of the best features of this tool is that it easily converts from trimmer to edger, making yard work more enjoyable. But, there are also many other great things that can be said about the LSTE525.

For instance, it has an EasyFeed system that lets you advance the trimmer line with just the press of a button. You don’t have to worry about having to stop what you are doing for bumping.

Other features include:

  • Increased Torque
    The PowerDrive Transmission gives you plenty of torque, so you have loads of cutting power. You can easily cut through some of the toughest weeds and vines in short order, so you can have more time to do other things besides working on your yard.
  • More Power/Running Time
    This tool has a two-speed control that allows you to decide if you want to have increased power or longer battery life. Each 20v max lithium battery lets you have a full hour of run time, so you should have more than enough time to get your entire yard done, even if your yard is a large one.
  • ​Trimmer to Wheeled Edger
    It is easy to convert this tool from a string trimmer to a wheeled edger. It just takes a couple of seconds to make the conversion, and you don’t have to bother with a lot of buttons. Simply press a button to switch from one tool to the other and back.
  • ​Comfortable to Use
    A lot of trimmers are bulky and awkward, and not at all comfortable to use. This is not the case with the LSTE525. Not only does it have a micro-texture soft grip for comfort while holding onto it, but the height is also adjustable, so it is ideal for anyone, no matter what their height or arm span is.
  • ​Batteries
    Having 2 batteries is great because you get a lot more run time. This unit comes with two lithium-ion batteries, and you can get up to 33 percent more run time compared to battery packs for other string trimmers from this company. The runtime extension feature lets you get the same speed and performance, no matter what the grass conditions are.
  • No Gas
    If you don’t like the idea of using a gas-powered trimmer that gives off emissions that are harmful to the environment, a battery-powered trimmer such as this, is a great option for you to consider. It has all the power that you would get with a gas-powered trimmer, but you don’t have to worry about it leaving a carbon footprint.

Pros and Cons

So, we have talked about the great features of the Black and Decker LSTE525, but this isn’t to say that there are no issues that customers have complained about.

Every product, no matter how great it is, has its little quirks, and this one is no exception. So, have a look at both the good and bad things that people are saying about this trimmer.

Pros of The Black Decker LSTE525

  • Less Body Strain
    The comfort grip and adjustability of this trimmer/edger make it a lot easier to handle than other comparable models. Because it is more comfortable to use, you won’t find yourself getting nearly as much back, neck, shoulder, and arm strain that you may have had in the past when using other trimmers.
  • Ease of Use
    When you want to convert this tool from a trimmer to an edger, you don’t even have to stop what you are doing. Just press a button and keep on working. It is easy to adjust the handle to a height that is perfect for you, and you won’t have any problems reaching tight areas, or even up high to get at the top of your hedges.
  • Cut a Wide Path
    This tool has a cutting swath 12 inches wide at the push of a button. This means that you are going to get a lot done in a short period of time. It is the ideal tool for creating paths and walkways in your yard, and you can get it done in a single sweep.
  • Batteries
    The batteries for this unit are interchangeable with other Black and Decker products. This tool can use up to a 7.5 amp hour battery. If you have other B&D products, you can save a lot of money because you don’t have to buy extra batteries.


  • Cleaning – Many string trimmers can be hosed down when you need to clean them. There is more work involved with this unit, because you can’t use water on it. The instructions say to not get the motor wet. You can only clean it with a damp cloth.
