Question: How many amps does the usb charging port deliver?
Document: I'll be re-ordering to give it one more chance; will update the review based on hopefully a working product. Side note, like the aesthetics and the usb charging port.
I LOVE this lamp. It is perfect on our computer desk. The light part is up high off the desk, and the lamp takes up very little room on the desk. I also love the usb port-it's perfect for charging my phone.
Great lamp with many features. I saw this reviewed on the Giz Wiz. Numerous light output choices. The charging port helps clean up the nightstand. This item was listed as a Prime product but took almost 5 days to arrive.
Excellent light with variable settings. Like how the arm easily adjusts and height is great near our 27&#34; monitor. Clean design and excited to have a usb charging port near my desk without having to use the pc. Overall very happy and went so far as to order a second for the household.
This lamp is a great purchase! Satechi has been a very reliable brand for me. The lighting choices are pretty cool. It also has a usb input in the back for charging, altho I haven't tried it. Also doesn't take up much space.
I bought 2 of these for office and home. Excellent functionality & love the usb charge port at the back. A little bit pricy for a lamp but really like them so far.
Sleek,  modern  desk light. Solid, well made, 4 light temps, timer function, and the usb port to charge a smart phone is genious!Love it, though a little expensive.
Bought to augment light at my desk office. Product is excellent. Flexibility with light scale and intensity have allowed me to adjust the light to what is needed (reading, computer work, etc.) at the time. USB charging works well for iPhone and IPod. Have received many compliments on the sleek style and unobtrusive look on my desk. Only ask would be to put a more powerful USB charger to be comparable to that which comes with an IPad. Nicely done Satechi!
Best light for reading I ever saw. Tone it down for a softer effect, set the timer, and go to sleep. The charging port is an added bonus.
Quite a nice lamp. It has a great range of light intensity. The timer feature is useful at night and the USB charger port is quite convenient for charging an iPad. I would recommend this lamp.
Answer: yes
