Question: So does it charge an Iphone 4 or 5 or not?
Document: I bought several of these for an earthquake kit making party I threw in my apartment complex. We all tested them at the party and everything worked as it should. One user said it does not charge IPhone 3 or 4 but we all charged ours just fine. Not only does it work just as described but the price on amazon is a fraction of the price you would pay at the hardware store. I saw this in my local hardware for $99!
description says it will work with iphone 3 or 4...neither supports this device. other than that, it is a hand cranked flashlight and radio.
I found this to be a great item to have, it allows me to charge my electronics in case of emergency.
I have several Apple products-it will not charge any of them...Not as advertised. Light is what you'd expect from an average cheap LED flashlight.Radio is functional, you get what you pay for.BEWARE-will NOT charge your cell phone.
I am disabled and live in an area with more than its share of blackouts. This will charge up my phone, at least enough to call if I need help. It will charge the flashlight and the radio which works petty good. Itm will charge my Kindle but that's a LOT of cranking!!!! !
a little surprised when I opened the box that there was no packing....and the device was just sitting next to its packaging. Will test out soon and update on the product itself. Because the shipping & receiving alone is a slight disappointment.
This is a great product and the maintainer I gave this to for Christmas was thrilled. Was a great and reasonably priced present.
It has come in very handy.You do have to crank it a lot. I am NOT sorry I bought it
I sent one to my son in Oklahoma, tornado alley bu place it in his shelter.the price is right also.
I cranked this up for the full minute and left it with the light on to see how long it would really last in an emergency and it outlasted what was stated on the package. Pleasantly surprised. Did the same for the radio - work good too though towards the very end the sound faded. Overall, the performance is better than expected. I recommend this product. I carry one in the dash of my car and keep another one with all my regular battery flashlights.
Answer: yes
