Saw this in my email from Joybuy.com, looks like a decent deal, it's new lamp from Xiaomi with 4000mAh battery that can be used as a mobile charger. Just copied the description below from Xiaomi News
CooWoo desk lamp is an environmentally-friendly LED lamp. This kind of lamp is considered energy-efficient and in fact it uses 75% less electricity as compared to other lamps. The other good thing about it is that it does not use wires you might have troubles with, and instead, it has a whopping 4000mAh battery that makes it run for 8 hours before it needs a recharge. It can be powered from your PC or a powerbank through one of the two USB ports or one microUSB. On top of that, it can also function as a mobile phone charger.
One of the major draws for people who like to read or have a work to do in the evening will be its non-flickering light. It is not too flashy to irritate you as it diffuses light well owing to a certified technology that protects your eyes from weakness and strains. It is excellent to illuminate a small area you are working in. The light source is 24 LEDs that can last up to 25 years under normal use. Its color rendering index is 83 Ra, which means that the lamp shows true colors of objects even in the evening.
Instead of a toggle, the lamp has a sensitive touch panel. A slight touch makes the lamp switch on/off and a more lengthy touch allows to change the intensity of brightness. The lamp also has memory and remembers what level of brightness you had yesterday at 8:39 p.m. and it will automatically switch to that level next day same time.
The base and the head of the lamp are made out of aluminum alloy. There is a silicone patch around the base to prevent the lamp from sliding. The LEDs are protected from overheating so you can light up your space for many hours without the heat. The brass gooseneck is flexible and permits you to tilt it and focus its beam as you like.
