I've been travelling a lot lately and more often than not I find my phones battery drained and not a single wall socket to plug it into. Do you know any good portable chargers which are already available in the market? I would really want to purchase one. Most of the chargers I see are Chinese made and I don't want to sound rude or anything but I don't really trust the quality.
There is what we call powerbanks. They will actually store a lot of charge and can be used when traveling. All you have to do is charge it before you leave the house. There are different sizes and the amount of charge that they can store. Carrying it around should not be hard as they are light weight just like a phone.
