Here’s the Ryobi version, that does indeed output 120v AC. It’s only good for 150w though. The Dewalt mentioned does indeed require multiple batteries to power it. The difference is it’s rated for 1800w. It’s also much bigger. Different tools for different needs. Both have their uses.
As far as running a modem and WiFi router. Sure you could make your own box and convert the 18v DC to 12v DC. It would indeed be more effecient. Probably be a little cheaper too. But it’s only going to work for devices that will then take that 12v or whatever you end up converting it to and uses the right connectors. And if that’s your entire goal then go for it.
The inverter on the other hand will run anything you decide to plug into it as long as it’s within it’s power rating. Just plug it in and go. No hassle at all. Your going to take a 15%-25% loss in efficiency at the inverter. But the versatility is worth the trade off IMO.
And yes one of these little inverters would have no problem running a modem and router. How long it runs is going to depend on the battery and how much power the devices are pulling. On average a cable modem pulls around 8w. A wifi router could be between 6w and 20w. You would need to look at your power supplies to see what they’re rated for. And ideally plug them into something like a kill-a-watt to know for sure. Figure out how many watts your pulling then compare that to the rated watt hours of your battery pack minus 20%ish for inverter loss. An M18 6.0 is rated at 108 watt hours. So probably good for 3-5 hours on an average setup.
