Q. So, I'm curious about what does A and mAh stands for and in what eays they differ. Cause I saw on the portable charger this output 5v-500mAH having a capacity of 8000mah, and in my samsung galaxy tab charger it has 5v-2A. Is it okay to modify this portable charger by changing its plug to be used on my galaxy tab?
A. No. Never modify a charger. Doing so could cause damage
and void any warranties expressed by the manufacturer(s).
'Ah' Stands for Amp Hours. 'mAh' stands for Milli amp (10th.
of an Amp) Hours. This means what current can be pulled
from the battery in a certain time frame before reaching the
point of 'time to be charged'. 5 Volts @ 500 mAh will not
operate your galaxy. This can only supply 5 Volts DC @ 1/2
an Amp! Your galaxy requires (at least) 2 Amps to operate
as the manufacturer intended. If you wish to operate your
galaxy from your car, you should be able to purchase a unit
(or build an adaptor) that can turn 12 Volts to 5 Volts. This
would require a 5 Volt regulator circuit. You can find such
a device at Radio Shaft, the 'fast food of electronics'. This
can be easily assembled if you have a good mechanical
aptitude and the ability to solder. Feel free to e-me.
What do I do if my Samsung Galaxy Note I stopped charging?
Q. I have a Samsung Galaxy Note 1. Recently I noticed it isn't holding a charge. I plug it in to the charger and it shows that it detects that it is plugged in, but the "percent charged" never goes up. I tried restarting the phone, taking the battery out, trying other chargers/ports. What should I do next?
A. Probably the battery meter and the battery itself goes out of sync. Here you can find a good discussion on fixing such kind of problem, for not holding charge, failed to charge, etc:

The discussion is for the Kindle Fire, but the same mechanism should work for any Android phones / tablets.
Why is my samsung galaxy S2 keep saying that its charging when really its not even connected?
Q. Okay so i have a samsung galaxy S2 and i have had for maybe 5 months and it recently started saying that its still charging when really it's not even connected to the charger like OMG! what's going on! Please help!! and also the worst part it that the battery drains like crazy!
A. Try pulling the battery, then put it back in and restart the phone. If that doesn't work, do a factory reset (your provider will help you if you don't know how). That should cure both problems. I think sometimes a conflict occurs in installed applications that causes a partial system crash, weird things like no sound from the speaker, but sound OK on the headphones, fast battery drain problems, GPS not updating position etc.
