hello, what do you think about this? Is the power bank and car charge suitable for my smart phone ? (this is my phone model Samsung Galaxy S - Wikipedia, the free encyclopedia)
I worry they would damage my phone. Like if the power watts not compatible, etc.
I heard that for re-chargable battery, lithium is better. But I am not sure if that's the same to powerbank.
It's $30, good or okay or not a good deal ?
