Do portable monitors need their own power source?

Most draw power from your laptop via USB-C. A few models have built-in batteries. For all-day use, the USB-C powered models are simplest since you never need to charge them separately.

Will a portable monitor drain my laptop battery faster?

Yes, roughly 10-20% faster depending on brightness. The ViewSonic VG1655 solves this with 60W power delivery that actually charges your laptop while displaying. Otherwise, just keep your laptop plugged in when using the monitor for long sessions.

What size portable monitor should I get?

15.6 inches is the standard and sweet spot. Large enough to be genuinely useful, small enough to slide into a laptop bag. Anything smaller than 13 inches starts feeling cramped for real work.
