External Battery Adaptor for Flash
Works well, easy to use.
Speeds up recharge time incredibly. No need to set or adjust anything, just plug it into the flash. Durable protective case with belt loop. Battery cover a bit difficult to open without some practice, not a big deal. I like it, does exactly what it says.

This is a great extra battery pack. Even though it isn't rechargeable, which isn't actually a bad thing sine rechargeables tend to lose charging power. Takes no time at all to recharge the flash and keeps up with the high-speed shutter firing. Will probably end up buying a second for the other camera. Very user friendly and easily attaches to the camera strap, tripod, whereever.

Not just a battery holder
This unit is not simply a battery holder as suggested in another review, rather it takes the 7.2-9V supplied by 6 AA cells and raises it to over 300V to charge the flash capacitor directly. The adapter works in parallel with the batteries already in the flash unit and recharges the flash much faster than the internal batteries alone can. It more than doubles the number of flashes available before the batteries need to be recharged. It also prevents the batteries in the flash unit from overheating and shutting down the flash during periods of intense use. By using inexpensive AA cells (rather than proprietary or built in batteries) you can easily replace cells that go bad while keeping the adapter in service for years. There are no switches or controls on the adapter as the flash unit automatically turns it on and off as needed through the plug in connector. I use two of these units with my flashes on tripods, triggered wirelessly. I love the versatility they provide.

You have got to be kidding. If you want to selll this thing it should be a rechargeable battery pack in itself with high end capability for duration and flash count.
