30 Volt Usb 3A To Micro B Cable

One of the Q&A’s says the Bescor BLS50AC dummy battery adapter kit is not compatible with the Olympus E-PL9.  I asked Bescor ( answers@bescor.com ) why the kit is compatible with the Olympus OM-D E-M5/M10, but not the Olympus Pen E PL9, since all three use the same Olympus BLS-50 battery.   The response was: “It will work. Your camera just needs to be added to our list.” The Bescor is 8V 3A. The Olympus battery is 7.2V 1175 mAh (1.175A).  I did some online research to see if a device built for 7.2V could operate at 8V.  One person describing himself as an engineer posted that 7.4V Lithium batteries actually span a 6V to 8.4v voltage range depending on state of charge of the battery.  Another “senior electrical engineer” said that because all devices are designed with some voltage tolerance value, a 7.4 volt device means 7.4 volt +/- 1 to 1.5 volts.  Still other posts indicated that you can use a 3A power adapter on a 1.5A device.  By logical extension, I figured (I don’t actually know) that since the PL9 uses a 7.2 volt battery, it is probably designed to also work at 8 volts, and is also okay running at 3A. Based on the response from Bescor and the Internet voltage and amperage responses, I decided to purchase the Bescor and use it with my PL9.  I haven’t seen any sign of overheating or other problems with this setup so far, but will update this review if that changes. I did not deduct points for the need to leave the battery compartment open because I knew that would be the case when I bought it.

The USB C PD powers my FX3 with 9V 3A for many hours.

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.

Needed this for charging from a micro-USB cable. Works great for that.

A+!!! I LOVE IT B&H!! 3

I have another review that I wrote about this mic, but B&H's website doesn't appear to let me update that review. I've now been using this mic almost daily for over a year. The audio is crisp and clear, background noise is kept to a minimum, and people on the other end of the meeting/phone call give compliments on the detail that this mic captures. I used to use a condenser mic, but that also had the annoying feature of picking up a lot of 60Hz hum. This mic doesn't do that and I didn't have to make any adjustments to the room either. For the person who mentioned they couldn't fit it in a shockmount, it has one internally. That is why the mic is the size that it is. For those complaining about the USB port, mine hasn't had any issues. I accidentally bent the micro usb connector on the cheap cable they shipped with it and the mic survived just fine. The cable, on the other hand, was useless after that. I solved this problem by finding a 90 degree USB adapter so that the connector isn't pointing straight out the back of the mic. It now sits mostly flush and swiveling the mic is more likely to cause the adapter to disconnect at the other end. If your laptop, like mine, is usb-c only, don't try to buy long usb-c to usb-c cables. They are crazy expensive. Instead, try to buy a usb-c to mini or micro usb-b cable. They are much cheaper. My setup is usb-c to micro usb (10 feet), then an adapter from micro-usb to usb-c (1 inch), and then finally a short usb-c to 90 degree micro-usb adapter (6 inches).

Buy a longer cord like the USB 3.0 A/ML to MICRO B/ML CABLE - 3'

The cable is well made, not flimsy. The USB & micro USB plugs plugged in smoothly with no struggle. Recommended.

By far the best and most reliable USB to Micro-B cable I've found. Frustration takes a back seat to quality.

I use it to power my Canon T3i as a webcam. No issues yet. Just make sure you have a USB brick with enough power (3A).
