A:AnswerHi,
If your portable charger provides 5V DC and 0.5A minimum (2A recommended), you can get it to work. On the other hand, I can not tell you how long it might run, this depends entirely on the portable charger capabilities.

A:AnswerThis is USB powered, so if you have a old phone charging block available you can plug this stop in that and that into the 120volt standard outlet
A:AnswerThe adhesive with this strip is sticky but will fall off after a few day. I bought extra strength double sided sticky strips cut it in a few pieces and used this.
A:AnswerThere is a multitude of double sided tape that you can get, I would recommend one of the foam double sided tapes they are extremely sticky and they can adapt to rough surfaces. Most hardware and craft stores carry a couple of different types of double sided tapes.
