USB charging question

1 week 17 hours ago #635048 by Joslyn
Good morning.  We are getting to travel next month and doing a quick inventory check on USB chargers, my husband and I have 6 items that charge via a USB charger that has a micro-USB on the other end.  

Seeing that these all kind of look the same, with the exception of color and shape.  Can these be swapped out with each other?  Which means when traveling I can get away with just bringing 1 or 2 of these?

Actually it would be great to have dual USB plug for a single outlet.  That way I can charge 2 items at the same time with out having 7 wires, 7 plugs.  

Currently I have each of these labeled, and I hoping I can consolidate the need for all these wires.  

Let me know please.  Thanks!

There are two types of USBs and the only difference is on the female
side of the connection: it may be or not; meaning that a connection will
supply current or not for a charger.

Males connectors are always the same so just make sure you have a po-
wered female available.

Most of those are all the same 5V, but where they can differ is the amps.  For example I have 3 on my desk right now.  One is from my Beats speaker and it's 2.1A, then I have a JBL one that is 2.3A, lastly one for a Sony camera and that one is 1.5A

I'm not sure of the range of power these devices can typical take before getting fried.  Might be a good question to ask the manufacture.  Perhaps someone here might know.

The cables are the same if the connectors are the same, aside from perhaps not providing power or adequate power. The only way to be sure is to verify at home before you leave.

You should be able to find a minimal set of cables to meet your needs. You might want to think about how many devices you wish to charge simultaneously.

The adapters can deliver different current levels. Take the most powerful. For example, the device I use for my iPad will charge my iPhone much faster than the device that came with the iPhone. Guess what I normally use?

Have a great trip.

You got that right, Howard, amperes are another difference but it is
waaaay less consequential.

If an equipment requires a minimum of power — say 3A — and the 
interface does not supply it, it will not work properly. If, OTH, the sup-
plied power is the zillion A, these are still at the same voltage that is
the only crucial value here. Voltage is a must in terms of working con-
dition as amperes are an operation availability.

:agree:   and the only way I know this to be true is that I was wondering the same and had asked my brother in law who's works with electronics .

Good question, I was wondering about this too.  I had seen the Amps are slightly different between some, but all had 5V.  I thought electronics were or could be sensitive, so I didn't chance.  Just to clarify, as long as they all have 5V, everything else doesn't matter so much?

Should read:

Just to clarify, as long as they all have the correct voltage,
A / amperes should never be less than the reworking re-
quirement but may be much greater? :P

I'm guess the question mark at the end "much greater?" is a typo then?  If it is, everything is crystal clear, thank you!

Sorry, I neglected to convert your question, my bad! :P

rement but may be much greater.

Voila!
