Spark, POVA and CAMON
Spark is the entry range - a current Android phone with a large screen and a usable camera for very little money, though HONOR and Xiaomi both start lower still. Spark Go sits below Spark.
POVA is the line to look at if battery life is your priority. These carry large batteries and fast charging, and they are aimed at people who game or who are away from a charger for long stretches. The POVA Pro and POVA Curve models move up into genuine mid-range territory.
CAMON is the camera line, and the CAMON Ultra models at the top of it are TECNO's most capable phones.
TECNO also makes the MegaPad tablet, which sits with the tablets rather than the phones.
