Cordless and Corded Power Tools

Many of us will need a certain power tool even for just some light task in the house such as installing a new cabinet or putting up a new photo frame of the family. Chances are you will need to have a small cordless drill or drill/driver to drive the screws and bits. When it comes to power tools, we will need to choose between a cordless and corded variant. Most of us will probably want the cordless type since it has greater mobility and convenience.

If you are still unsure about which to choose, let’s see both the advantages and disadvantages of using both systems. With corded power tools, they are almost always going to deliver plenty of power or more than the cordless variant and since they are continuous, as long as there is no power outage in your working area, then we have no time restriction on using them thus, we don’t suffer from drop in performance over extended use. Additionally, they tend to have greater torque as well.

Coming to the cons, the most obvious downside of corded tools is the mobility. We always have to struggle with the extended cable while using them and moving to another spot means rearranging it around the piece as well. If you are doing home improvement, we may have to buy an extension cable or power cord to reach the tricky part or when working in the backyard. In addition, the corded tools can be tricky to handle or store compared to cordless for the long cord which can get damaged too overtime.

Now for the cordless tools, the best thing about this simple and compact design is that we can work anywhere and anytime. Of course as long as you have the battery charged already. For us who often work outdoors it can be a great solution to not use extension cord or moving closer to the house to get the power source. It is also essential for workflow, especially if you move often or work on a jobsite since it reduces the necessity to bring a dedicated power source too.

While it sounds like a perfect solution, being dependent on the battery also brings some cons and one of them is loss of power. Even with a backup battery, you will notice that the torque or power will decrease over time as the battery is being depleted and the longer you need to work, the more battery we will need or at least bring a charger when it is a jobsite and outdoor works. Additionally, with a battery meaning your tools will be heavier so it may add strain to your hand.

About Dewalt 20V MAX XR and Flexvolt

Not all of us will have the same preference and it is best to choose based on what you want to achieve or what the tool must offer when it comes to the application. Corded and cordless systems are equally useful but probably for different people and it is fine to have both to match with the need for the project or place where it must be done. Power tools are coming from so many different brands and most of them are also reliable.

For those who prefer corded tools, usually the battery will be compatible with the other tools from the same line or as long as they are using the same power rate such as 12V, 18V, or 20V depending on the rating they carry. Companies can develop battery lines as well for their corded power tools such as what Dewalt is doing. This company is probably few among the top options when it comes to corded power tools and even jobsite tools such as Dewalt DWE7485 Vs Makita table saw.

Currently they offer various different lines including the battery and one of the newest versions is Flexvolt. Many are already familiar with the Dewalt 20V MAX XR batteries and tools for how reliable they are but now Dewalt seems to improve their system even better. We are going to focus on the battery side today but you can find lots of different tools that are using these batteries from the collection and in fact, we can use them for each other’s tools as well.

The 20V MAX is probably an older system since XR is the newer one developed for the higher efficiency and if you see the power tools line, The XR also means that the tools are using brushless motors. Several years ago, Dewalt also launched a new line called Flexvolt and this is very similar to the MAX XR for the tools in this family are also housing brushless motors. The difference between the two? Flexvolt is more versatile as we can fit it in higher 60V or 120V tools too.

Dewalt 20V MAX XR and Flexvolt Batteries 

There are several different variants or capacities that you can find for both Dewalt 20V MAX XR and Flexvolt but today we are going to specifically talk about the 5.0Ah and 9.0Ah. You can buy them as a single battery or in a pair and with the charger too. We can find the tool set depending on what power tool you want to have. Since these are quite a large battery, the shape is designed to slide at the bottom of the handle.

They are going to lay flat and can help the tool to stand on their own as well. In comparison the Flexvolt is a larger battery and this is why it is heavier too compared to 20V MAX XR. As you can see they are housed in a sturdy plastic just like the cordless power tools in their collection. Installing and removing the battery is very easy based on the tools mechanism but our favorite part is they are also featured with fuel gauge.

Dewalt 20V MAX XR and Flexvolt Technology

Now for the most important part, let’s see what the Dewalt 20V MAX XR and Flexvolt can offer starting from the technology. What makes Flexvolt special is because they are designed to be compatible with higher tools and not only limited to the 20V range. We can use it with either 20V MAX or 60V MAX tools and this is because the battery can detect what the tool is requiring for it to work. Dewalt gives the battery an ability to extend the run time for 20V or deliver more power for 60V and 120V.

In the mechanism they use battery pack wiring or wiring lithium-ion battery cells in a series to increase the voltage since wiring rows of cells in parallel will deliver greater amp hours. For example, you can get a 20V MAX pack or 18V nominal pack by arranging a set of 5 battery cells in series since each cell produces 4V MAX or 3.8 nominal and the series connection will multiply it to make 20 volts.

Dewalt 20V MAX XR and Flexvolt Convenience

We all love cordless power tools for the same reason and it is convenient. Dewalt is upgrading this convenience by releasing the Flexvolt batteries because cordless tools are drawing different amounts of power. For example a drill may only need a 6 amp. motor while a miter saw required a 15 amp. motor to perform properly and each motor has an amperage rating. However, the power consumption is measured in watts and with Flexvolts, the tools that draw fewer watts for their brushless motor will use the 20V MAX configuration.

When you pair them with a higher cordless tool, the battery will detect this and use the 60V MAX configuration. On the other hand, the 20V MAX XR is only compatible with the 20V tools as it is not designed to produce greater power than how the arrangement is set up.

Dewalt 20V MAX XR and Flexvolt Performance 

Lastly for the performance, both Dewalt 20V MAX XR and Flexvolt are very similar depending on the operation and also capacity that you are choosing. Especially for Flexvolt since it has a wider compatibility with higher tools. They also have different capacities and for example a 5.0Amp with 9.0Amp will run at different times using the same tools. They are working really well and personally we have no issue with how they deliver the power and how they last until you need to charge them again.

Dewalt 20V MAX XR Vs Flexvolt

Both Dewalt 20V MAX XR and Flexvolt are good options and they are used by so many different power tools in the Dewalt line. The main difference is that Flexvolt being the most convenient battery system Dewalt currently has because it is compatible with different power ratings unlike the 20V which is only made for tools that require 20V batteries. The Flexvolt can be fitted for tools that run on 20V, 60V, or even 120V batteries.

- Premium XR Lithium Ion pack provides up to 60% more capacity than standard DEWALT 20V MAX battery pack (DCB200)
- 3-LED fuel gauge system of DEWALT battery allows immediate feedback on state of charge
- No memory and virtually no self-discharge for maximum productivity and less downtime
- Lightweight at 1.4 lbs and compatible with entire line of 20V MAX tools
- DEWALT 20V/60V Battery has 180 Watt Hours of energy in each battery pack (360 Watt Hours combined)
- DEWALT battery has 6 times the runtime compared to DCB201 1.5Ah Battery
- 9.0 Ah capacity when used in a 20V MAX* tool
- Compatible with 20V MAX*, 60V MAX* and 120V MAX* tools


The decision is all yours because we may have different preferences and tools to use. We recommend Flexvolt if you will use or buy different tools with different power ratings in the future since it means we don’t have to invest on a new set of batteries.
