Document: It's a pretty cool product given that it's a battery with a light, or a light with a battery! It's green for the environment since it has solar in it. It's got a radio and even can charge USB products. If you need something for emergencies, you can't go wrong with this. It would be great for hiking trips, or when you won't have access to electrical plugs for a long time. Good for the car to keep in case of emergencies.
It is set up now to be lo-medium-high. I would like to have more control, but that's not a big deal.The flashlight is great. I have used it late at night in the house and to go to my basement. One thing, silly and minor but great, is that it is white. When the light is off, I find it easily in the dark.Anyway, I am ready if the power goes out or there is a storm.
Cool LED Desk Lamp and 3-year Guarantee! Solar Rechargeable Cordless LED Desk Lamp with Phone Charger, Fm Radio, LED Emergency Warning Light, Siren, USB Port, LED Flashlight, and Dynamo Hand Crank. When Not Serving As a Modern Table Lamp, the Powersafe ...This is a REALLY nice desk lamp! I have it by my computer most of the time.
I wanted to wait a couple of weeks to make sure I was as happy as I was when it arrived. I am happier.The product is everything as advertised, but it is what I have used it for that has me convinced. I use the light at night on my desk to work late. It is bright, clear, white light. It's nice not to have to plug it in because of where my desk is.I listen to the radio late at night.
I am very impressed with the versatile line of products DTC Lifetools offers. This is my 2nd tool which I have acquired in the past couple of months. Specifically designed to use as a desktop lamp, it also functions as a flashlight, radio, a blinking light, and an alert siren with a blinking orange light. The greatest feature this portable lamp/flashlight has to offer is that it is completely independent from having to be plugged in to a wall outlet  to charge this unit.
But it definitely seems sturdy and am hoping it'll run for good.I am giving 4 stars only because of 1 reason, that it didn't come with detailed instructions. There is one page instruction inside, but at this price I would expect them to pack a nicely written instructing book inside.
I bought this mostly just to use as a desk lamp, but now that I have it I'm impressed with everything else it can do. It works great as a lamp (very bright at max), but I'm getting a lot of use out of the flashlight and USB charger, to the point where I'm actually keeping it in my car instead of on my desk. Very handy.
I have used this lamp for one month and I really like it. It's very useful and multifunctional. Although the button on the lamp is little bit uncomfortable when I have to turn on/off, it's a still great product. It's totally worth to buy if you like camping.
"Awesome product!!! Is it sad that I can't wait for the next power outage. I brought this product to prepare for the possible active storm season coming up. It's a great little gadget , light weight, and more importantly does what it claims to do, the radio works great and the the phone charger too. The siren is definitely loud :) I'm ready for you 2013 storm season !! "
As I sit an write this, I have had the radio feature on for at least 1 hour and 15 minutes and it seems to be strong. The radio does not really have a "wow" factor, but it works well and receives a solid signal through the internal antenna. I used this lamp portion of this item this earlier this morning while I was at my workbench cleaning up and reorganizing my bench.
