Zoom H5 Recorder

If you're in the audio industry, you probably know this one. It lets you record audio on the go, but using professional mics! It has 2 inputs for 2 separately controlled channels.

It's also not a bad interface by itself. Let it replace your Scarlet 2i2! It's also got a great on-board mic. Let it replace your entire mic setup! Although it's a bit sensitive to plosives, so get a deadcat if you're using the on-board mic.
