How good DIY can I do with this

it will be fine.

Battery charger not included?

This should be fine for most small projects. Corded saws have more power so will cut faster. I find that these cordless saws draw enough power that the batteries drain very fast and need to be constantly recharged. Even cycling through 2 batteries wasn't enough to keep up when I was using it for an extended period.

You can see it's well reviewed, so I'm not sure what the question is (424 reviews with a 5* rating). It won't be the tool that limits the quality of your DIY work...

The only real concerns I'd have are:
a) It doesn't come with a charger, so you'd need to have one from another kit or purchased separately. It's a "Bare Tool" saw and a battery add-on.
b) It comes with a 2.0Ah battery, which is pretty small for a saw. If you want to work all day on a deck, you'd probably want a larger battery or a second battery so you can charge one while you're using the other. Especially since you'll probably want a Dewalt drill/driver, which will also be chewing up batteries.
c) Don't know about the quality of the blade it comes with. I use a Freud thin kerf blade in my corded PC circular saw. I've had it for years (like 15 years), and it still puts and AWESOME edge on anything I cut with it. But I'm just an average homeowner type, so it's not like it's getting used 8 hours every day.

Thanks all

I’d get a mitre saw. If you’re only going to have one circular saw, I’d go for corded. Circular saw with that tiny battery won’t last long.

Agreed, if a deck is what you want to build, then you want a mitre saw over a circular.

In my opinion battery saws are a niche product because you don’t get enough runtime out of them to work on a project. For that reason they’re mostly for quick and dirty fix and patch work where it wouldn’t be convenient to lug around a cord - best example would be a battery reciprocating saw for pruning trees. Sure you could get more batteries but you’d be constantly changing and charging that will kill the life of your batteries. I’ve seen videos of similar saws where they tested the runtime - in general you’re only getting about 100ft of material cut on a 2x4 before the battery dies.

How strong is this saw? Is it good for 2x4 or 2x6 cutting, future Deck building and etc?

Trying to find a way to convince the GF into buying it lol

pass. It would make your 0 dyi a 6 on the dyi scale. EDIT; ok, 4 not 6.

100% if you are building a deck you need a 10” mitre Saw. I have literally every tool in the world and I rarely use my circular saws. Mitre Saw is the go to winner for so much.

I do use a circ Saw for breaking down sheets goods that are too big for my table saw, but those are rough cuts.

If you're thinking about building a deck or anything that requires some nice measured cuts I'd go Mitre and save some money towards a work/saw horse.

Good advice on the mitre saw, more useful and safer for a newbie compared to a circular saw.

Often when a circular saw is required you will need more run time/power than a battery circ provides. I have the complete line of dewalt 20v, worklight-all saws to radio. Sold off the circular saw and bought the corded version. Building a deck for example, its nice to just let decking boards run wild on the outside-especially if laying boards on the diagonal. Snap a chalk line and use the circular saw....if the decking is 5/4 you might get half an average deck done. If the decking is wet 2x6's a battery circular will drain all your batteries for a 40 foot run.

Buy a corded saw unless you really need the portability. For DIY corded will be less hassle, cheaper, and more powerful.

I second below statement. OP you should also consider mitre saw that fits in your budget

Cordless tools are great with not having to deal with a long extension cord, cords wrapping up in your work, or finding an outlet. But nothing more frustrating for a DIYer when you've realized that you forgot to charge your batteries, or you've run out of juice just hoping to make "one more cut."

Despite what others have said 9 times out of 10 i grab my battery powered circular saw for most DIY jobs. You can do a lot of cuts with a circular saw and a straight edge or speed square. You definately need a second battery though or you'll get frustrated. At an average DIYer speed you usually won't run out of juice while alertnating batteries.

That being said for a big job like a deck or fence there are far more efficient tools, like a miter saw.

But if your only going to have one saw, I'd go circular because of its diversity, portability and cost.

Agreed, if one plans on only ever having one saw, it should be a circular. However, usually once you go down that path, you'll start buying other saws, and the circular saw will see the least use.

I have both corded and cordless circular saws. Initially I only had a corded one. After I bought the cordless one 4-5 years ago, my corded one has been collecting dust in the corner.

The cordless one is so convenient. I can take it to any end of the wood or high on the ladder/platform to make the cut without dragging the line and also don't have to worry about tripping on the wire at the worksite.

I have set of cordless tools from drill, driver to saw using the same battery. So if a battery run low, I just use one from the other tool. I usually run out battery on my drill or driver before the saw.

Some tools that I need constant power from the cord such as hammer drill, impact gun for car suspension knuckle nuts or axle nuts, etc. So those tools I bought the corded ones.
