This is the latest addition to my Samsung Galaxy smartphone garget
It is a charger portable charger for the phone when in urgent need (meaning away from home n now charging adaptor)
A few times phone battery flat while on tram.. end up cannot check email or listen music or WORST… cannot play Angry Bird.
Had to pocket out $12 for it now (label at $18 but I get little discount) as I need this wonderful tool to keep my phone alive when on AirAsia (8hrs trip) at end of the month.
The only concern now is how long a AA battery can “tahan” for this purpose….
