. Tecno is all set to launch its Spark 40 series smartphones next month. Today, we have spotted some of its models on the TÜV Rheinland certification database. The listings not only confirm the presence of the devices but also shed light on their battery capacities and charging details.
According to the TÜV records, at least five different model numbers linked to the Spark 40 series have received certification:
- Tecno Pop 10 Pro (KM4k) – Likely a rebranded version of the Spark 40C
- Tecno Spark 40C (KM4n)
- Tecno Spark 40 Pro+ (KM7)
- Tecno Spark 40 Pro (KM6)
- Tecno Spark 40 (KM5 and KM5n)
Tecno Spark 40 Series Battery and Charging Details
All models, including the Spark 40, Spark 40 Pro, and Spark 40C, are listed with the same charging input specifications: 5.0VDC or 7.5VDC via USB, or 3.91VDC / 3.92VDC via rechargeable Li-ion Polymer battery.
- The Spark 40C (KM4k and KM4n) variants come with a 5850mAh battery.
- The Spark 40 (KM5, KM5n), Spark 40 Pro (KM6), and Spark 40 Pro+ (KM7) carry a slightly smaller 5060mAh battery.
All these phones comply with the IEC 62368-1:2018 safety standard and were certified by TÜV Rheinland Japan Ltd between June 6 and June 12, 2025.
Furthermore, the company has already confirmed that the Spark 40 Pro+ will be the first phone to feature MediaTek’s new Helio G200 chip, promising a 10% performance boost over the previous G100 model. With an AnTuTu score of 470,000, the upgraded Mali-G57 MC2 GPU now runs at 1.1GHz, while custom super-resolution algorithms enhance graphics rendering to 1.5K for sharper visuals.
It will also arrive with the Dynamic Communication Smart Adaptive Response (DC SAR), which will optimise 4G connectivity in weak signal areas for faster data speeds and smoother streaming or gaming.
