Make a portable, multicharging device for your electronics, that will let you recharge your stuff in your car.
Step 1: Gather stuff blah blah blah...
Ok, in order to make this fun and easy device, we'll need:
1) regular USB hub (bought mine at 1,99 store priced at R$ 7,90 -- about US$ 3,50)
2) car lighter cell phone recharger that outputs 5VDC@>500mA (I happen to have a LG Scorpio KP215 cell phone, so I bought mine for this model on a street seller for R$ 13,00 (about US$ 6,00) -- this happens to be a bonus, check it later)
3) hot melt glue (optional)
4) electrician black tape (we don't need crazy wires touching each other)
5) multmeter (optional, but ok to check cables, etc. I learned I had a bad cable -- later on this)
