Those heat pads heat up alot. So it should be more than enough for the pacman frog you get. But you would also need a thermostat for the heat pad. You can buy cheap ones on Amazon that are made for plants / seedlings. Those are what I use on my tanks they work exactly the same a Zoo med reptile thermostat and they are a a lot cheaper. Just plug in your heat pad into the thermostat and set the temperature you want it at. They work exactly the same.
