Blackberry Micro Usb Charger Voltage

[USB: 5 V / 2 A] I have two of these chargers. They are well built and powerful. However, that power comes with a string attached - if you want to rapidly charge a Mavic 3 battery the input voltage has to be greater than produced by a typical full charged 12 volt battery. DJI tells us this - stating that we should use the charger only with the car running. However, the specifications state that the input voltage needs to be 12.7 - 16 volts DC. Which led me to assume the 540 amp hour 12 volt battery bank in our expedition truck, which delivers 12.8 - 12.9 volts when fully charged would be sufficient. That is not the case - I need to have somewhere between 13.1 and 14,1 volts minimum (closer to 14.1 I suspect) for the rapid charger to work with an Mavic 3 battery. I can work with that as long as I charge during the day with solar input raising the voltage of the battery bank or when the truck's engine is running. This charger will work fine charging a Mavic Mini 2 battery bank with the supply at 12.8 (perhaps lower as well - I've not tried that). It might also charge the Mavic 3 battery via the USB 2 - USB 3 outlet but at 10 watts I'd presume that would considerably slower than the 65 watts possible with USB 3 - USB 3 outlet. I have not tried my car chargers with large portable power banks like those from Goal Zero or Jackery. I suspect the same restraints would apply - rapid USB 3 to USB 3 of a Mavic 3 battery will require solar or other supplemental input. Again - not a problem if you plan for that. I've given the charger 5 stars because it is great and works well as long as one respects the design parameters.

[3' / 0.9 m] [This review was collected as part of a promotion.] I'm so glad I chose this micro USB charger from Belkin. The length of the charger is perfect for my needs, not too long or too short. The best part is that it charges extremely fast which is a big plus when charging my devices. This is a great product from Belkin!

[Micro-USB-B] Micro USB cords are common everywhere. Glad to have this gizmo which functions just as well as my OEM adapter but the fit is more firm, secure. Very useful bc a lot of my devices take micro USB which I always have on me. Always great to have options. Plus OEM and some Lightning charge cords aren't durable. Inexpensive (3 pack price is great) to have these adapters on my micro cords or in bag. Naturally paranoid and cautious, I have yet to try data sync with it. Still trust OEM for that specific job. *(This is no directive, I’ve evaluated for what worked from my experience, your needs and results may differ. Engage at your own risk.)

[22 AWG] This is a must-have piece of kit in my opinion. If you have spare batteries or a charger that has d-tap and the right voltage/amps this enables you to use it on the BMPCC 6K Pro to just add all day battery.

[Lithium] The charger and batteries work well, I made a mistake of buying some other rechargeable batteries with the wrong voltage for my 35mm Nikon which sadly didn’t work. These came, I charged them, put them in the camera and they made my old camera work great!

[LCD Display] I immediately unpacked, plugged-in, and started testing and charging batteries when the Watson Duo arrived. Mounting a battery with the device unplugged from power, the screen reports the percent remaining charge left on the battery, and pressing Test, the measured voltage from the battery. Finally, no more balancing VOM, +/- probes and the battery to track voltage loss! Plugged-in, the charger reports the same information for each battery on the display, and indicates it's charging by the flashing top unit in the graphic battery indicator. Love it!! Wanting to change battery plates, I held the charger in my hands like playing a game played using thumbs, and pushed one of the plates towards the back of the charger, like I would with any of the plates for my eight year old Pearstone plug-in-the-wall chargers. The plate would not budge! Tried the other plate on the other side of the Duo, same thing!?!? Confustion ensued, LOL!! The manual has a minimal graphic showing installing the plate, not taking it off. So, after fiddling awhile and dismissing the use of screwdriver, it was back to thumbs pressed and squeezing hard against the corners of one of the plates, then progressively increasing the pressure applied, until it popped free! It took several similar remove of a plate from each side of the Duo using this technique the plates supplied with the Duo were easily removable. The good news is that my Pearstone plates are the same plate as the Watson plates. They fit perfectly on the Duo, and mount and dismount easily. I really like the features on this charger; the voltage/capacity display, the USB power/charging output, the car adapter input and being able to charge a different type and/or voltage batteries at the same time on this charger. Highly recommended this Watson Duo for its simplicity, quality and features. I always look for great value over the long-run, and this charger overwhelmingly fits the bill. Thanks, AGAIN, B&H!

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).

[14.8 Wh] I love that it can work with either micro-usb or USB-C cables. The LEDs provide a nice monitor of your charge progress. Really like this little charger.

[0.03 lb] Needed this for charging from a micro-USB cable. Works great for that.
