Got a big fencing project planned for next month and considering getting a nail gun. The pneumatic ones seem cheaper but I don't have a compressor, so wondering if battery-powered is worth the extra cost.
Guys pretty much nailed it already but lemme add my two cents from the accounting side since I've done enough DIY projects to know the real cost breakdown. If you don't have a compressor, you're looking at dropping another $300-500 minimum on a decent one, which completely wipes out any upfront savings you get from cheaper pneumatic guns. Then you're also tied to an extension cord or air hose, and honestly for fencing that's gonna drive you crazy when you're moving along the property line. Battery-powered is genuinely the better play here.
The other thing people don't always think about - maintenance and long-term costs. Pneumatics need regular upkeep on the compressor, oil changes, checking seals, all that stuff. Electric ones are basically set it and forget it. I've got a DeWalt 18v that I've used on and off for like 5 years with zero issues. Batteries do eventually need replacement but you'd probably get 5-10 years out of them depending on how much you use it. For a big fencing project that's happening once, electric just makes more sense financially and practically.
Only caveat would be if you already own some good 20v or similar batteries from other DeWalt/Makita/whatever tools you might have. Then the gun itself is cheaper to buy. But buying a whole new system just for one project? go electric. You'll thank yourself when you're not dragging an air hose through dirt and mud.
For a fencing project electric is the way to go if you don't already have a compressor. yeah pneumatics are cheaper upfront but you'd need to buy the compressor too which kills that savings. modern brushless cordless guns are plenty powerful for fence nailing and way more convenient - no hose dragging around, and you can work without worrying about air pressure drops.
The previous answer nails it - for fencing you'll be out there for hours and a cordless electric or battery model gives you way more freedom without needing to lug around an air hose and compressor setup. Plus modern lithium batteries hold up pretty well, and you can grab a second battery to swap out if one dies mid-project, which beats being tethered to a cord or dealing with hose management on a fence line.
As someone who's done plenty of work on job sites, I'd definitely go electric for a fencing project - the freedom of movement without an air hose is huge, plus you avoid dropping several hundred on a compressor you might never use again. Battery-powered nail guns have gotten really solid over the past few years and honestly they'll pay for themselves in convenience alone on a project that size.
I'll throw in what I've learned from doing this stuff. I drove past a fencing job last summer and stopped to chat with the guy - he was out there all day with a battery powered DeWalt and said he'd never go back to pneumatic for residential work. The thing is, as mentioned above, once you factor in a decent compressor you're looking at real money, and for a one-off project it doesn't make sense.
From my own experience with board games, I'm used to weighing whether gear is worth it for occasional use versus something you'll actually keep using. Same logic applies here. A battery nailer lets you work at your own pace without managing hoses - you're not getting tangled up in air lines while you're trying to focus on straight fence lines. Yeah, you might need to swap batteries partway through the day depending on how big your project is, but that's honestly no big deal. Charge one while you're using the other. The cordless electric ones have come a long way and honestly most folks doing fence work these days are using them instead of pneumatic.
One thing though - if you ever think you might do more projects down the road, that's different. But if this is just a fence, stick with electric. You'll spend less overall, have way more freedom of movement, and you won't need to maintain or store compressor equipment you might never use again.
