Question: cell phone charger?
Document: Possible uses in developed countries for the device are:1. Power failure. In a power failure, this is stress free. Just crank it and you have both light and some juice to charge your cell phone. No more anxiety about being in the dark without communication! If you get tired of cranking it you can put it in your car and charge it!2. Camping trip. It's a natural on a camping trip.
Other reviewers have stated that it's a 1.0 USB and that it won't fully recharge a cell phone but as long as really works and it does, I don't really mind. In an emergency I'll take whatever I can get and be very grateful.I'm also very pleased with the lanterns LED lights. As soon as I got it home I turned off all the light in the house and turned it on.
After purchasing the Lighthouse Lantern we decided it would be a great gift for my mom/dad in case of a power outage ect. They loved it and now most of our relatives have one. The lantern can be used to increase the charge of your cell phone (cell phone does pull the lanterns battery down rather fast) but is primarily for light, about 8 to 10 hours of it after charge. Can also be charged by using the sun with my Goal Zero Nomad 7 which is also another great product.
Also can be cranked charged and has a 12V car charger. What else could you need in a lantern?
Good light but I was hoping it had a solar charger also. Guess I have to keep cranking it.The light seems to have 4 vertical beams which is a little disturbing when walking around at night
Well made yet affordable item, charges with crankhandle, as well as included power supply, or USBport, can charge cell phones with this lantern
It was a gift to my son who travels. He took it camping before he left and found he could charge his phone from inside a camper. Made his night. It was very cold and rainy. He loves it and now ours will be a plus also to our home. Thank you
It's a lot brighter than I expected. I haven't used the charger on it but I don't really expect to. I bought a EasyAcc 10000mAh  and a EasyAcc solar charger panel pack bag, that's how I plan to charge anything with a USB. I guess it's nice to have the option if needed. It also has a crank, but I don't think I'd need that either, but once again, a nice option if needed.
Goal Zero is one of the better products around. I absolutely love the multiple charging options. I also have the solar charging panels from Goal Zero for other purposes and they work great also. The camp light doesn't charge my phone completely but it isn't designed to do that. It does, however, give me that security if I ever need to use it to charge my phone in an emergency. This is a well built product and does what it is designed to do. I recommend this product.
_ arrived promptly from amazon as usual._ features accurately described as usual._ by all appearance the design of the product is very thorough and excellent!_ the materials and construction are likewise excellent!_ only improvement I see would be charge/charging indicator-s._ nice surprise when we recently needed to re-charge cell phones during a power outage --it had arrived pre-charged and was therefore ready for service!_ I highly recommend these for any households or campers!OLDDOG
