With Manners specially designed charger cap, accumulators in radio telemetry systems (e.g. in automobile wheel transmitters) can be quickly and simply charged without having to open the electronics casing.
The cap can be either powered by the vehicle power supply (12V) or a mains adapter. A charger circuit controls the accumulator charge, preventing overloading by automatically switching off at full capacity (ideal for overnight use).
Simply place the plastic housing on the sensor electronics in order to recharge the long life accumulators via induction.
