I am very happy with this purchase and it has only been a day since I received the lamp. It's a very versatile piece of hardware. It doesn't have fancy features like wireless charging, but it still includes a basic USB port for charging your devices. The coolest thing is mobility though. Thanks to its built in battery, you can cary the lamp untethered around your place. I do not know yet how long the battery lasts, but I have used it unplugged for a couple of hours with no hiccups.
