A Type B plug in North Korea?
Not directly — pack an adapter.
North Korea's Type C / Type F / Type A sockets don't take a Type B plug. A plug adapter solves the shape problem — it changes pins, not electricity. The wall delivers 220/110 V at 50/60 Hz (198–242 or 99–121 V within tolerance) — if your device isn't rated for that (look for "100–240 V" on the brick), an adapter won't save it.
