    Watson NP-BX1 reviews

    NP-BX1 Lithium-Ion Battery Pack (3.6V, 1150mAh) is rated 4.6 out of 5 by 49.
    Rated 4 out of 5 by from Inexpensive alternative to Sony NP-BX1 I bought this battery as a backup for my Sony RX-100M3 camera. The Watson battery works fine in the camera and seems to have a similar life to the stock battery, though I haven't done a precise comparison. Note that the Watson NP-BX1 is rated 1150mAH, while the stock Sony NP-BX1 is rated 1240mAH. 90mAH (about 7%) probably won't make a noticable difference. One oddity about the Watson battery is that the contact layout is backwards from the Sony battery. Actually, they're the same in terms of the form factor of the battery, but the Watson labels are applied backwards. This means you have to flip the battery upside down to charge it in the Sony NP-BX1 charger, and you have to turn the battery 180 degrees to insert it into the RX-100M3 camera. This appears to be deliberate because the matching Watson AC/DC charger contacts are also laid out backwards from the Sony charger. So you put the Watson battery in the Watson charger right side up. Very strange. Last but not least, the price of the battery makes it a great value.

    Rated 4 out of 5 by from Good alternative It works perfectly fine. I only give 4 starts because it doesn't tell you that the lables are reversed and you need to charge it on the Sony adapter in the opposite side. I had to find out the hard way. It was not charging on the Sony adapter and after going to the internet found the answer that you had to flip it. I guess if I had looked at the contacts I would have known but I didn't think of it. There should be a lable somewhere on the package explaining how to charge it in the original sony adapter. I know watson has their own adapter but since it is made for a sony equipment it should have the disclosure. I haven't use it long enough but so far so good. Excellent alternative and much cheaper than the Sony.

    Rated 5 out of 5 by from Great Battery I purchased this Watson battery as a second battery for my Sony RX100M3. The Watson battery is just as good as the original Sony battery but at a much lower cost. This battery is a great value.

    Rated 5 out of 5 by from Holds a charge, works as well as Sony Bought this as an extra battery to work with my Sony Actioncam HDR-AS15. Works perfectly and holds a charge for the same amount of time. Will probably pick up a few more as the need arises.

    Rated 4 out of 5 by from NP-BX1 Li-Ion Battery Good battery for about 2/3 the cost of a Sony version. Holds a charge for almost as long as the Sony version.

    Rated 3 out of 5 by from We need more power! I'd read that the RX100V had a great appetite ....well I can confirm that now. Either the camera is too power hungry for this type of battery or the batteries are just not strong enough but a fully charged battery does not take you very far. Just familiarizing myself with the camera drained the battery.....NO extensive photo/video-taking sessions just going through the camera's menus & a little experimenting was enough. Glad I bought 2 extras with my order & I wonder if this will even be enough for a typical day of touring in a European city.
