What ive got this week is the portable charger by Anker Powercore. This is one of the smallest and lightest portable chargers on the market. When the device is fully charged i can get a little more than three charges on my iPhone. It comes in handy because a lot of the time i need to charge my phone at least once throughout the day. Sometimes this takes place in a car or outdoors where i do not have access to power. The device uses high speed charging to help get power quicker than normal. I have heard mixed things about the effects that this might have on your battery so i am still somewhat hesitant. Overall I think these are super useful and I want to get one soon!
I think that it could be useful to have one portable charger that is capable of providing power for all of your devices. This could be a laptop, tablet, or phone. There are products that currently do this but the price point is a lot higher.
