Citizen Watch Automatic Change Power Battery

This change the way a watch films. The bass from this sub is incredible.

-let me take over 500 flash shots without a flash battery change -maintained flash recovery time and flash power

I like the flatness and the automatic sleep for long battery life.

I now have three LP-E17 Battery Packs and when staying in Hotels I would have to get up every few hours and change them out. Now I just need a power chord and I can charge all three all night and get some needed rest.

I love being able to change the battery and keep the finding going....

Nice to know I have power left and not having to change out batteries as often.

This seems to be a well-made, powerful flash. Understand that there is no automatic anything - no TTL, P-TTL, E-TTL, and not even an Auto mode where the flash reads the light. You set power manually. For my needs as strobes to light a room, you can't beat this. Flash PLUS radio receiver (technically transceiver) for this price? Amazing. Plan is to set up four to light a space (say, dance floor) and then using the controller on my camera, I can trigger the flash automatically -- as well as adjust power, zoom and other functions. Unless reliability becomes an issue, this is a no-brainer.

I use it to provide conditioned power (uninterruptible as well) to my computer and all peripherals. The automatic voltage regulation is as, if not more important to sensitive electronics. Under voltage and over voltage can do bad things to electronics and it is not as apparent as a power outage, spikes, or brownouts. I have another of the same on my TV, cable modem, DVD player as well. You hook it up, it works, you do nothing (except change the battery every couple of years). I have a Mac and their software doesn't run on a Mac. But it is no big deal as you really don't need it.

As a senior citizen it is hard to hear dialogs. It is much much clearer.

This Battery Grip has saved me from having to change out my batteries, thank you!
