This B&H kit puts together three Switronix products: an XP-L90S V-Type 14.4VDC Lithium Battery, a PB70C PowerBase Charger, and a Powertap BlackMagic Converter Cable. The kit is designed to be an end-to-end power solution for 12V devices with field applications, such as the BlackMagic Mini Converter HDMI to SDI.
From the battery, the cable inputs unregulated 11-17V DC power via its Power Tap (P-Tap) connection, and outputs regulated 12V power to devices that require it, such as a BlackMagic Design Mini Converter. The Powertap cable also features a female P-Tap to supply 11-17V DC power to an additional device.
The XP-L90S is a V-Mount (Sony-style) Lithium Ion battery that supplies 14.4V DC power and features a 90Wh capacity. The kit's included PB70C PowerBase (9-250V AC) fully charges the battery in 4-5 hours.
