Help Charging question.

Hello Good People,

New guy here and Thanks Rob. Can anyone please answer these questions. I have an LG G3 and an LG G Pad 8.3 LTE. Both came with identical 5V, 1.8A chargers. I have a New Trent charger that has two ports. One outputs 5V, 1A and the other has an output of 5V, 2.1A. I also have an iGo charger with an output of 5V, 2.1A.

Can I safely, without issue, charge either of my devices with either the New Trent or the iGo chargers? I've done a lot of research on this and my understanding is I should be safe. Correct me if I'm wrong, but it looks like volts is where there would be a concern and since all chargers are 5V, it should be OK. The New Trent charged my previous Samsung Tab 7 nicely using the 2.1A port. Do devices "draw" only the amps they need so there is not a concern with amps? Do devices cap amps? Most of the charges that came with my older phones were less than one amp. I've read it was cheaper for manufacturer's to provide those and a 2.1 A charger will simply charge a device faster.

Further, would the 1A port on the New Trent charge either of my devices? I suspect it wouldn't.

Lastly, can I use any USB/micro USB cord with my chargers or there specific power and data cord?

WHEW! Lot of questions for a first post eh!

Thanks in advance for any replies. Please feel free to add any and all technical info that applies to this.
 
Hi!
I would surmise you are correct. 5 volts is the number that would be of concern and your devices will pull--in amps--only what they need.
If one device wants 1.5 amp, and you have it plugged into the 1Amp charger, it will charge slower, that's all.

At least that is my understanding:)

As far as any micro USB cord...there are some that are known just for charging and not data transfer. I don't think there are any micro usb cords that are strictly data only are there? Now you got me thinkin' :)
 
Thank You Mikestony. With my Tab 7, the 1A port would not charge the tablet. I'm not sure about the data cable only.
