Where is the best place to find a micro USB power adapter?
I always buy my charging cords from WinnerGear. they have the best products i have used so far and everything is made using quality material so you know it will last and they are reasonably priced. They just came out with a new type of micro usb that is fully reversible micro usb cord. Its awesome because no matter what side you are trying to plug in it will always work. And its the same price as just about any other micro usb cord on the market. I found the cord through this unboxing video on YouTube
Using “old” 5W iPhone 5 Power Adapter to charge new iPhone XR.?
Hello, I would like to know if it is safe to use an “old” 5W Power Adapter (charging brick) from an iPhone 5 to charge my new iPhone XR. I am specifically referring to the original (and, of course, genuine) charging brick that my old iPhone 5 included in the box. Yeah, I know that my new iPhone XR already includes a cable and a 5W Power Adapter... However, I would like to have two chargers (one at my work and the other one at home). I would definitely need to purchase a new lightning cable... But, my question is... Is it necessary to purchase a new charging brick? Could the “old” charging brick damage my new phone (since it is too old)? It seems to work fine. It worked perfectly with my iPhone 5, but I am not sure if I should use it on my iPhone XR. I know that this question may seem stupid, but I prefer to play it safe. Thanks everyone and sorry about my English (my first language is Spanish).
What is the difference between ac adapter and power cord?
The simple answer: If it has a transformer built into the cord, it is an AC Adapter. Normally the transformer changes the wall socket voltage from 110/220 volts AC (depending on country) to the lower DC voltage required by the device. This then powers the computer, or whatever. A laptop is a good example of a device that uses an AC adapter. If it doesn't, it is a power cord. (Like a regular household extension cord, but with a special end to plug into the computer.) A power cord delivers the full household AC voltage to a power supply in the computer, TV, etc. and the power supply converts it to the various DC voltages required by the circuits. BTW: Some people call an AC adapter a power cord! I've even seen them misnamed in User Manuals for devices that used AC adapters.
I have a USB AC Adapter with 5V .55A output. Can I use it instead of buying the recommended 5V 1A AC adapter?
You always run the risk of damage if it's not the recommended charging device. The voltage however is the important factor here. You can use it if it's the same but any less or more runs the high risk. The lower Amps will slow down the charging process or may even say "not charging" like in the case of some iPads. It will still charge just take longer
Is USB power grounded?
The USB drive will be grounded adequately to prevent susceptibility to electrostatic discharge. It is very well isolated from the power line; surges there would fry the computer's power supply before it reached the hard drive, and that would protect it in most cases, except maybe for a lightning strike right on your house.
Can I replace my USB hub's AC adapter that says "Output: 5.0V---3A" with one that says "Output: 3.0V---4.0A"?
My USB hub has an AC adapter that says "Input: 100-120V~0.5A Output: 5.0V--3A". I want to use my USB hub internationally, so that adapter won't work with the higher voltages. I have an extra AC adapter from a battery charger that says "Input: 100-240V~0.6A Output: 3.0V--4.0A". So that one will handle international voltages. I already tried hooking it up to the USB hub and it seems to work. But since the output specs don't match precisely, am I likely to run into problems? Or are the two adapters close enough that it should work without a hitch? Thanks for any info or advice!
Does charging multiple devices on 1 USB power adapter reduce charging speed?
It is a simple application of Network Theory that those of us who have studied electronics will recall. The voltage source is fixed and the current in the circuit is limited by the load. Plugging in another device to the same charger is like adding a parallel load, which means that the current is now split in two in the proportion of the attached load even though the voyage across all loads are constant.In short, yes it obviously does. Think what happens when you open all taps connected to an overhead water tank vs opening just one tap. The pressure in the tank is constant but the rate of flow will decrease proportionally.
