Wat on NP-BX1 Reviews

Works Well. Good value

I ordered these Watson NP-BX1 batteries after ordering the Watson charger for the orignal sony NP-BX1 batteries because I realized I could get two Watsons for the cost of one Sony. Having recently purchased the Sony RX100Vii camera, I noticed how the battery life was no where near as long as I was used to on my A1 or A9ii, so I decided I need a few extra batteries for a full day of travel shooting.

Excellent battery pack

Will it work in my RX100 V1?

Will it work in my RX100 V1?
Asked by: Charles
I purchased the Watson NP-BX1 battery for my Sony RX100 VI and it works just as well as the Sony batteries. The camera is hard on batteries and I usually carry 3, particularly if I plan to use my camera all day. The only issue I've had with the Watson battery is that I find it easy to place in my charger incorrectly. Fortunately, the charger then blinks rather than going into charging mode.
