if it is before the on/off switch for lamp then it will charge when lamp is off. If after, then most likely not. It will not hurt to plug your phone in and see if the charging icon comes on
It should charge any usb device but it may be slower depending on the device requirements.
I have an inexpensive desk lamp with a USB port in the base (5V DC, 1A). It has no directions, other than those numbers and saying it "powers phones, tablets & more." I don't have wifi. Does this mean it would charge a phone ? Does the lamp need to be turned on while the phone is charging?
Thanks. Please excuse my lack of knowledge about this.
