Sorry to burst your bubble, but this seems like a very poor idea. The lamp looks well made, however the phone charging outlet is just poor in many aspects. The the glass will easily heat up and burn someone if they accidentally touch it. Assuming that does no harm, the electronics in phone chargers are very sensitive. You might have noticed that after charging your phone with a normal outlet for a while, it heats up. This heat combined with the heat of the lamp could easily cause capacitors to leak, plastic to melt, or the chips to fry. This could even fry your phone! Great idea, but please do not charge your phone with it.
