Android Usb Charge Voltage

I use this usb to charge my samsung android phone.

I use these to charge android phone and connect USB C drives.

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.

[This review was collected as part of a promotion.] This Belkin wireless charging stand is top notch. The fastest charge I've seen for my Android phone (it also works for non-Android products as well). Included in the box are a 10W wireless charging stand, 4 ft. cable power supply, and a USB-A to micro-USB cable. There is an led light that updates the status of your charge. Your phone is secure on the charger because of a non-slip grip. An all-around great charger and I highly recommend it.

If you have an Android smartphone, you probably use a micro-B plug to charge it. With this adapter, you can take a USB drive (thumb drive) and plug into this adapter and then into the phone. Now you can copy all those pictures from your phone onto the USB drive. I hope this helps!

I'm a HUGE fan of this device....especially when used with an Android phone, which all you need is a USB A to C adapter for. If you wanna do videos or podcasts with great audio on the go...without bringing a computer...this is the way to go. Will this drive an sm7b? No....no it won't...but most dynamics it will...condensers, no problem. I just snap a klark teknik ct1 onto this thing for sm7b use...still ultra portable, and the price of both is just over a hundo. For the record....I've owned TWO Shure x2u devices....both went bad. Go with this for ultra portability. [I received this product in exchange for my honest review.]

I used it to charge my Hummer EV for two months dumping from solar collected during the day. The Double Voltage Hub melted after two months. I was glad that it wasn't the Delta Pro that smelled like fried circuit board. Worked great .......for a while.

I think this Battery is even better than the original version from Canon because the voltage is higher and it can hold more of a charge than the original Canon Battery ! It's a great buy at a great price ! Truly !

Love this charger as it seems to charge my batteries faster then the one that comes with my camera. It will charge one or both battery at the same time. It will charge two different type/voltage of batteries at the same time! The adaptors for different batteries need to be purchase separately but they are not expensive. The unit will also check your battery voltage and how much charge if left in the battery in percentage. Clear LED display. Display always stay on but not so bright that it will annoy you at night. - highly recommended item.

We use from 15 to 20 of these radios about 8 hours each day. They hold up very well and are the most reliable of all the Midland radios that we have used over the years for our business. In my initial review I mentioned that the battery had a short life. Well in fact, the battery is great. The problem is that the radio charges the batter very rapidly. I never timed it but it must be within an hour or so. What happens with this rapid charge the charging current is high enough to cause a high resistance spot on the battery. Because of this high resistance the radio circuit thinks that the battery is charged because it has reached the battery full charge voltage. However, this voltage consists of the battery voltage PLUS the voltage drop across the high resistance spot on the battery. As a result the battery never reaches a full charge. If you are experiencing this problem remove the battery and look at the negative end and you will see a small spot that is a high resistance burn due to the fast charging. As a test I would wipe off this spot and the radio would charge the battery completely. Solution: I purchased some conductive past at our local hardware store, which I applied to each end of the batter. This has eliminated the problem. I have had no undercharges since I began using this paste with all of our radios.
