If you have some problems to charge your phone battery or other lithium one. I suggesting you to have at least two batteries and use the Portable Charger. There is a unique Portable Charger that I have found on my town. This is my review, check this out :
 
The positives of this Universal Charger that I liked :

1. Suitable for charging a lithium battery in capacity up to 2000mAh
2. The power switch with high-perform have voltage range about 110-240 Volt.
3. The charging process be more accurate by genius LCD vision
4. The charging process controlled by micro chip at high speed and efficient, and at your battery in full-charge the process stopped automatically. So it is safe and practically.
5. The size and weight are suitable for mobile. Suitable for lithium battery in 3.6-3.7 Volt
6. Easy adjustment. There is a pair of needle to adjust at the battery’s pole.

The negatives :

1. be uncomfortable, when you charge at tight place. Because the size is be bigger.
2. Need an extra terminal. Because in my country, that kind of terminal is very rare. Look at the picture
3. This just the universal charger. Of course the result will not optimal as the original charger.
