Small, handy, well-made power, sufficient light for reading

The applications for such a lamp are varied. First we think probably because the lamp to a USB port to attach the laptop and thus to illuminate the keyboard. My laptop has an illuminated keyboard and also I work often in complete darkness on a laptop.

I use the USB lamp in conjunction with a Power Bank (eg: Poweradd Mini 5000mAh External Battery Power Bank with USB 2.1A Buschse for iPhone 6 iPhone 5S 5C 6 plus 5 4S 4, iPads, Samsung Galaxy Note 3 Note 2 S4 S3 S2 , Other Android smartphones, tablets, digital cameras, MP3 and other 5V USB charging devices Smartp ...) while traveling as a reading light. Some hotels may save the meantime the bedside / reading lights on bed.
The small USB light can it be bright enough so you can read and relax without headaches. The consumption is kept within limits. My 5000 Powerbank enough reading pleasure for up to 7 hours.

The bulb is small, handy and fits loosely even in the laptop backpack or luggage. I do not want to miss anyway.
