Baofeng K5 Plus vs Baofeng UV-21R

The UV-21R is the better choice. Both radios have identical feature sets, identical owner ratings of 4.5 out of 5 stars, and CHIRP support. The UV-21R's single concrete advantage is that we have its transmit power specification at 6 watts, while the K5 Plus has an unknown TX power figure. We cannot assess the K5 Plus's actual output capability without that data. The UV-21R also benefits from a larger owner review sample at 775 reviews versus 506, giving slightly more statistical weight to its 4.5-star rating. The price difference is negligible at four dollars. The K5 Plus is marginally lighter at 290 grams, but both are ultralight radios and this difference is insignificant for most users. The UV-21R should appeal to anyone wanting confirmed specifications and more owner feedback behind their purchase decision. The K5 Plus could interest budget-conscious buyers willing to accept missing technical data. For most users, spend the extra four dollars on the UV-21R and get a radio with known output power and stronger owner feedback. The missing TX power spec on the K5 Plus is too significant to overlook at such a close price point.
