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.
Can a mini usb cable charge the sony tablet?
Q. I am thinking of buying the sony tablet s. I need to charge it in the car and using solar chargers. I can only do this using usb. so does the mini usb charge the sony tablet or not? If not do you recommend the iPad 2 or the Samsung Galaxy tab 10.1
A. Err .... No, I have the Sony S too, and, you can only charge it via the flat 4 pin plug + PSU supplied.
Even with the 'on the go' lead, it won't chatrge vioa micro USB.
Should I buy a Samsung Galaxy S2 or iPhone 4s?
Q. I currently have the iPhone 3s, and I'm ready to upgrade. I love how smooth the iPhone OS is, but I feel like the Sammy might have more options for customization and utility.
A. Since I'm in the same boat and actually just got the Galaxy S2 yesterday. I will tell you my experience.
The pros: The phone is amazing! It's got everything you would want. It takes a little bit of getting used to though, but it didn't take me too long.
The cons: If you've used Itunes for music before, you're in for a big hassel of getting all your music on to the new phone, trust me, I've stayed up until just now trying to find the best program to do it all. I thought I found it in isyncr, but there has been conflicts to connect the phone to my PC. Anyway, long story short, the program Kies is STUPID! It doesn't even work. I was lucky I got my contacts transferred over at Best Buy or else, that would be time consuming too.
Another con is if you've used IOS, I still feel that the text messaging and typing tool of the IOS is Wayyyyy better than anything Android although the "Talk to text" is a huge plus.
So coming from being an IPhone user, I never thought about the accessories that I would want to consider like getting a case, screen protector, and car charger (trust me, the battery life isn't as good as IPhone). Having all that already for IPhone, I realize how much money I could save on accessories. I'm considering ordering the IPhone 4S and taking this one back.
I hope I don't regret that decision, but I have a feeling the IPhone 4S is going to be way better than my initial thought at the announcement.
Anyway, hope that helps you. I'm leaning on IPhone 4S. And if I get that, at least I get a free headphone lol... The Galaxy S2 only came with the charger.
Good luck on your decision.

Experience... at least with Galaxy S2 coming from a previous IPhone user.
