At times it can get tricky getting your key in the keyhole when you’re drunk, but i’ll have to say connecting your smart phone and charger in the dark can get trickier, at least for me. The guys at CordLite thought the same thing, introducing a illuminated charger cable that light up at the tip giving you full visibility at night so no more messing around. The product is still in production but you can pre-order yours today. (retail $30)
