Wasabi Power NP-BX1 Battery (2-Pack) and Dual USB Charger for Sony NP-BX1/M8, ZV-1, ZV-1 II, Cyber-Shot DSC-HX95, HX99, HX350, RX1, RX1R II, RX100 (II/III/IV/V/VA/VI/VII), FDR-X3000, AS300, and More

Sony RX100M7 digital cameras come with only one battery and no charger; the battery charges in the camera, which is inconvenient at the best of times. Enter this Wasabi Power dual USB charger with two NP-BX1 lithium-ion batteries. It’s the one absolutely vital accessory out of the several that I’ve purchased so far for my camera. The clever little charger snugly accommodates two NP-BX1 batteries. Hook up a microUSB cable to the charger, plug the other end into a power source (not provided, but you can use the wall-outlet transformer that comes with the camera, a computer’s USB port, a power bank, etc.) and you’re good to go. Bright LEDs for each battery glow red when they’re charging and then turn green when charging is finished. I tested the unit with both 1A and 2A transformers, and it worked fine with both; charging times will be different, of course. It also charges the genuine Sony NP-BX1 that came with the camera, or a combination of that one and a Wasabi one. And, despite what a previous reviewer stated, it WILL still charge if only one battery is installed. And while I’m about it, let me correct a couple of other errors in previous reviews. The Wasabi battery is rated at 1600mAh vs. the OEM Sony’s 1250mAh rating, so it has MORE capacity, not LESS, as several reviewers have stated. And at least one reviewer claims that these batteries don’t fit in the RX100M7. WRONG! They fit perfectly. You have to pay attention to orientation when you put one in the battery compartment, but it most definitely DOES fit and DOES work fine when properly installed. For a camera such as the RX100M7 that eats batteries, having some fully charged spares on hand is key to successful photographic experiences, and this Wasabi Power set does all that it needs to do at an extremely reasonable price. I most enthusiastically rate it at five well-deserved stars for its design, construction, materials, utility and value. If your camera uses NP-BX1 batteries, this is an accessory that you need to add to your equipment stash.

They work fine in my Sony RX100II

These batteries were purchased for an old digital camera. These batteries work well. Their temperature seems to be appropriate; I am not concerned about overheating. Battery life is good. These are a well-priced replacement option.

I did a comparison of battery life in my Sony RX100 III by putting the camera on a tripod, pointing it at a clock, and starting video recording (1080p). I charged the original (year or so old) Sony battery in a Sony charger, the new Wasabi battery in the Wasabi charger, and recorded video, restarting the recording every 30 minutes (the max recording time on the camera), and waiting to see how long it took to exhaust the charge on the battery. The Sony battery lasted for slightly over 90 minutes, the Wasabi battery for only about 60 minutes, even though the Wasabi battery is specified to have larger capacity. So the Wasabi battery has in actual use only about 2/3 the capacity of the Sony battery, but an extra Sony battery costs 4 or 5 times the price of a Wasabi battery, making the Wasabi battery a good value for the money. I'll probably use my 2 Sony batteries as my primary batteries, but it will be useful to have a couple Wasabi batteries as spares for long hikes or vacation days. The USB charger that came with the batteries is quite nice. It appears to work with Wasabi batteries and Sony batteries, and being able to charge two batteries at once is very handy. It has a light for each battery slot that is red while charging, and green while charging is complete.

Love the batteries. They are compatible with my Sony zv1f and I love them .

Works great!

I’ve owned Wasabi batteries and chargers for other digital cameras and have had good experience with the. I do like the fact that this product’s included charger can charge both batteries at once, and the included charger is small, making travel easier (I actually purchased two of these kits, and it will make it easier to charge 4 batteries at once. The one item that would make this kit even better is if it included two small plastic cases (1 per battery) for safe transport…

These batteries charge & work perfectly.
