The Aaronia AA17600mAH External Powerbank is designed for use with the Aaronia Spectran V3, V4, and NF series of handheld spectrum analyzers, the BPSG series of signal generators, any Aaronia active antennas, and the UBBV series of pre-amplifiers. This 12V version comes with 17600mAh, including a 12V (1A) output with 300mm cable (integrated Aaronia special DC connector) and 5V USB (2A) connector. The powerbank extends the run-time of a Spectran V4 by approximately 10-15 hours. The AA 17600mAH also works as a hot swap system as it charges the internal battery of all units when connected. The power bank includes an integrated metal clip for use with a belt or can be carried in a pocket. This power bank offers 2 independent charge outputs, so 2 different devices can charge at the same time.
