Q: 1. Can I plug my Norman 400 into the PC connection of the Vello and install my Nikon SB-910 on the hot shoe connection of the Vello and have them both fire simultaneously on my D300 and D3s?

A: Sorry, melahat m, your question is out of my range. I recommend that you contact Vello directly via their website and ask them the question. They were happy to answer my questions about this same vello adapterand were very helpful. Good luck in your search. Barry.

Q: 2. I am going to use this hot shoe adapter to connect the Samsung NX10 and Godox AD100 Pro with a PC Sync cable. Will it work?

A: While it is possible to use the Vello HSA-PVU Hot Shoe Adapter with Safe Voltage Conversion to connect a Samsung NX10 and a Godox AD100 Pro using a sync cable, it has not been tested to our knowledge. Your results may vary.

Q: 3. This unit runs on a battery. My question is, if the battery fails in the middle of a shoot, will it make it impossible to fire the flash from an older power pack? Or will it still fire with potential damage to the camera?

A: According to Vello, they state that if the battery dies, the HSA-PVU Hot Shoe Adapter would still provide voltage protection for your camera. However, the PC sync terminal may lose the ability to trigger the flash or power pack connected to the adapter, depending on the voltage needed to trigger the unit. So the short answer is if the battery dies, your camera remains protected, but the flash connected to the adapter may not fire.

Q: 4. What is the warranty on this product?

A: The Vello HSA-PVU Hot Shoe Adapter with Safe Voltage Conversion includes a limited 1-year manufacture warranty.

Q: 5. can this battery be checked on commercial airlines?

A: sorry ,you can NOT fly with this Battery .

Q: 6. I have a digital Leica CL and a Contax G flash. Will this adapter work properly , fire the flash and protect my camera's circuitry?

A: Yes, the Vello HSA-PVU Hot Shoe Adapter with Safe Voltage Conversion will protect the Leica CL when using older flashes that had a higher voltage from the Shoe. And the flash should work in manual on the camera.

Q: 7. Will this trigger a Profoto A1X?

A: This adapter would not work with the Profoto A1X.

Q: 8. This unit runs on a battery. My question is, if the battery fails in the middle of a shoot, is the voltage protection disabled or will it allow high voltage from an older flash power pack to go to the camera?

A: Don't know. It doesn't work at all on my Olympus or Nikon cameras. Total waste of money for me.

Q: 9. What is the maximum wattage if converting from 110v to 220v? (I am in North America with an EU product).

Q: 10. Two products that I have recently purchased from BH, first, Wein SSH Safe-sync, second, Vello HSA_PVU Hot Shoe Adapter, have both failed to fire the flash which is a Norman studio power pack connected via PC sync cord. I am connecting to a Nikon D3300 via the hot shoe on the camera. The camera hot shoe works to fire a portable flash connected directly, so I don't think there is a problem with the camera's hot shoe or maybe this camera cannot handle external flash connections? Nikon says that it can. What to do? Would a radio powered transmitter/transceiver work? Is this a camera problem? Thanks.

A: Unfortunately, we do not have enough information to assist you via this forum. The best I can state is if the camera's hot shoe is working properly, I would recommend trying the adapters with a different flash to see if the adapters fire with a different flash. If so, the issue may be the sync terminal of your power pack or the PC sync cable you are using. At this point, you have only eliminated the hot shoe as properly working, but have not identified if the adapter, sync cable, or sync terminal on your pack is the issue. All other variables have to be eliminated to find the issue. The above test would verify if the adapters are working. Switching a PC cable with a known working flash would indicate if the PC sync cable you are using is working. If the adapters and PC cables are all working with other items, then the issue may be the sync terminal on your power pack, which would need to be sent to Norman or a repair center for inspection/repair. If it is your sync terminal, then purchasing a wireless radio remote system would not work as they still utilize the power pack's sync terminal to connect the radio receiver/transceiver to the power pack. I would recommend to use the items you currently have to confirm or eliminate the issue. As you state the hot shoe on the camera is working, it does not seem to be a camera issue.
