Got this on sale and it does what it should do. Reliable and easy to use.

I have one of these as a back up for my run and gun fx3 rig for sports and unfortunately, somehow with the combination of the 2 products, the battery seems to be lightweight that it easily pops out of its v-mount. I've tested with other heavier batteries and they've all worked, all locked into place with no give after some resistance was given. Good thing these have usb ports, as I'll just use this to charge my laptop on the go or something else

Will this power a Canon C50 via USB-C? There’s not a lot of official info on the C50 power draw but some claim it has to be 65w PD. This only does 45 but wondering if anyone has real world experience with it.
Asked by: Ricardo
Yes, the SmallRig VB50 Mini V-Mount Battery (50Wh, Black) can power the Canon EOS C50 Full-Frame Cinema Camera (Canon RF) but they recommend using upwards of 65W compared to the max 45W for stable recording without issues in higher quality recording.
