Anything you can think of, really, that doesn't exceed 175W.

Only limited by the battery you're using, or the number of batteries you have.

The USB-C output is going to be the most efficient, I believe, since it's not converting from DC to AC. It's only changing voltage really, DC to DC.

Converting to AC you'll have some losses. As far as the shitty sine wave, anything with its own power supply should be fine (e.g. router).

Consider the M18 12.0 HO battery. It has 216Wh of full charge. So, 216W for one hour. Or, 21.6W for 10 hours, for example. Say your router uses 21.6W --> the M18 12.0 battery should be able to run it for 10 hours. However, the inverter is not going to be 100% efficient. Neither is the power supply of the router going to be 100% efficient.

Say you lose 30% between the DC to AC conversion and the router power supply. 216Wh --> 0.70 = ~150Wh. If the router uses 20W --> 7.5 hours, under ideal conditions.

(Please, anyone, correct me if I'm wrong or have missed something).

My top off has mostly been used as a USB charger, but recently was great for powering the modem and router during a 4 hour power outage.

It is pretty cool, and handy. Especially with a 6.0 HO battery included! I have one, and like it. Just keep in mind the AC output is a really sh*tty modified sine wave.

Just ordered. With tax and shipping total was $149. Still solid deal for a very good battery and an item (top-off) that rarely goes on sale.

Yes it could run a wireless router outdoors. Something very odd that it is amazing for is powering a CPAP/BIPAP. If you use one you would know that being able to use it anywhere would be amazing. Think use it in a car, used to be able to take batteries on planes (not the case now) and the biggest is camping. Nothing worse than not getting decent sleep when you are out camping.
