there is difference between cellphone and tablet chargers
First let's talk about the kind of damage that I may be doing unknowingly to my devices which may include:
· Poor battery performance in long run because of improper charging
· Too slow charging (low current) may take hours to charge the device
· Too fast charging (high current) may affect the circuitry, touch screen performance (not kidding, it may cause static charges which affect touch screen response)
· Overheating may damage the battery prematurely
· In worst case, damage to circuitry because of improper current (may kill the device gradually)
Too much current, like using a 2 Amp charger on a phone which is designed for 0.8 Amp or 1 Amp charging may heat up the battery, may hurt the circuitry or may make it misbehave because of static charge build up.
Too low current (using a 1Amp charger for a tablet designed to charge with 2 Amp charger) causes less damage, but slows down the charging cycle which may deteriorate the battery charging levels or performance in the long run.
Solution 1: Don't be lazy, use the matching charger only
This is the easiest way to sort such troubles, is to use the supplied charger only with each of the devices so that they are being fed on what they are supposed to eat. You may have a bunch of cables and chargers looking messy, but it is better for long life and safe operation of your gadgets.
Solution 2: Remember charging current for all devices (recommended)
You can also remember the charging currents and pick two chargers to charge all of them. Like for tablets, which charge on 2 Amp, use a 2 Amp charger of any of the tablets and use it to charge all your tablets. And your phones which may charge on 0.8 Amp or 1 Amp, you can use one charger of 0.8 Amp (pick the lower current one, as it is safer) and charge all your lower current devices with it.
This leaves you with fast charging for fast ones, slow for slow ones and less clutter on your wall ports.
