Recently I purchased a couple inexpensive items which are quite handy for hookers, particularly when traveling to rug camps. In all honesty I didn't know either existed until Cape May rug camp when my roomie had them.
The first is this TRANYA lightweight portable and chargeable 3-level dimmer light.
Matter of fact my son used it for light as he was hooking up my TV and assembling the TV stand.
Another very handy item is the surge protector cord which I purchased from Walmart. Mine came in white, black and pink with 2 usb ports. However the link I gave you shows 3 usb ports as I couldn't find this one on-line.
What a great deal, you can plug is your OTT light, charge your cell phone and ipad all at the same time while hooking....or while sleeping.
