SWIT LB-SF65C Reviews
It will only power on USB-C and disconnects the D-Tap.
I recently purchased a Teradek Ace 500 and when I connect the FX3 by USB-C 7.3 Watts/1.6A and the Teradek Transmitter by D-Tap 4.8 Watts it will only power the one on USB-C and disconnects the D-Tap. I've also tried connecting my Sennheiser Profile Wireless receiver and you can only use one or the other, not both. Very Unfortunate.
Long Term test underway
Everyone and their sister make versions of Sony's popular NP-F series batteries, which have become the standard for powering a wide variety of portable video & audio gear. This SWIT branded product is one I decided to try because of its novel rapid-charge system. The QC 3.0 here uses a USB-C connection for the Qualcomm interactive charging chip that was pioneered years ago in Android smartphone systems and external battery packs. Later adopted by Apple devices too. The system greatly reduces the risk of overcharging and burning out a battery, while achieving shorter recharging times than older systems. The product under review is among the first to expand the QC system to the NP-F type of battery. It works great, based on about a half dozen cycles of use and re-charge so far. I am using a high powered QC 3.0 smartphone charger and USB-C cable that came with my Samsung Galaxy S20. Charging time is way faster than the factory Sony charger that uses the battery terminals. The battery itself has far greater capacity than a Sony of equivalent physical size. Oftimes this will mean a shorter overall service life before the battery no longer retains useful capacity after charging. So, we shall see whether it's a good tradeoff between extended duration on a given charge, versus when the battery is worn out. Other notes: I have not tested the D-Tap connection. Presumably the QualComm chip is a DC-to-DC converter to boost the battery's nominal 7.2 volts up to the 12 volts anticipated when powering an accessory off a D-Tap. The documents note the D-Tap is output only, maximum 25 watts. The USB-C can accept a QC charge or a regular rate charge, and can also be an output to charge a smartphone. The battery housing is built well, with mounting flanges within tolerance, and the D-Tap cover staying in place. The plastic. case feels thick, does not flex on the sides when pressed, and the heat-sealed seams are nicely finished between the main housing and the mounting face.
