1.5 Volt Batteries Usb

Some cameras, right out of the box, must be charged through the USB port - inconvenient if you have back up batteries. I purchased this unit from B&H for my Sony A7 and am glad I did. It is far more versatile than most chargers. Apart from 110 volt capability, it has a 12 volt lead for automotive use and as if that weren't enough, there is also a USB port. As usual, the B&H price and service were the best. Watson also offers a line of replacement batteries, and the one for my Sony is excellent - no problems!

Great buy on quality 9 volt batteries. My smoke detectors use 9 volt batteries.

This tiny switch can run off a 1 volt output from the USB port on my UPS. That makes it incredibly useful.

Works just great. When you order be sure and get 2 - 9 volt batteries ... B&H didn't tell me this and they sold me one ... which meant I had to run out and get another to make it work.

I use this to power my Zoom H4n recorder using a USB to 5 volt cable. I set levels, press record and record my band all night with no worry of changing dead batteries.

I had some issues using the Volt 176 with USB 3.2 Gen 2 (10 Gbps) ports and I think it was causing the inconsistent playback/distortion. The two older USB 3.2 Gen 1 port (5 Gbps) work with this interface with no issues. Overall sound quality is decent for the price, the only downside is the lack of clean gain for dynamic mics so you may need a booster depending on which model you have.

Great for charging multiple batteries and the ability to charge from a 12 volt source is great for when you are traveling and need to top off your batteries.

I really like that these 9 volt batteries have plastic covers for the +/- contacts. This allows me to place spares in my camera bags without needing to find a bag or box to prevent a battery from shorting out.

I use this to recharge the batteries for my Nikon D500. I have only charged two at the same time once - when I first received with two new batteries that were down to about 15%. I like the fact that it shows the capacity of the battery, each individually. There is also a port for charging a USB device (5 volt - 2A output) I have not used and it also came with a short cord to connect to the 12 volt outlet in the car so batteries can be charged on the way to or between shoots which might be necessary when using Nikon's adapter for wireless flash as it does pull the Nikon D500 battery down rather quickly.
