Newbie Noob paranoia battery/charger concerns

Hi just got my phone and it's great but a curse at the same time cuz I'm super paranoid when it comes to preserving the battery.

I was wondering why the models differ and if I use a charger that did NOT come with my phone (I used a charger that my friend got with their nexus 4 phone) will it damage it? I'm just worried cuz it took a while to reach 100% when I used my friend's charger. My model is mcs-01wd and my friend's is mcs-01wr. The specs are the same. The user guide says "only use the travel adapter that came with your phone or else a different one may damage it" can someone ease my worries? Lol. Thanks!

I'd appreciate any feedback. Thank you!

I've used 3 different chargers and never had any problems. Some people have reported some wonky behavior using other chargers, but in general I don't think it's anything you need to worry about

Wont damage but it might charge slower or faster.

Glad to hear that! It took 5 hours to fully charge using his and 2 hours and 40 mins using mine. So weird!

different power adapters draw different amounts of power depending on the model of the adapter. The phone, however, will never draw more power than it can handle from a power adapter. The kernel limits that. that being said, I have heard that comsistently using power adapters that charge at 2 amps isn't good for batteries in devices that charge quickly at or around 1 amp.
