What is Bulk Rate? BulkRate is a semi-wholesale system with items priced separately from retail. When you use bulk rates, a flat $1.70 registered air mail fee will automatically be added to your cart to ensure delivery of package. While BulkRate's intention is to offer cheaper prices when you buy in bulk, because it is priced separately it on occassions show a higher than retail price. That's why we ask you to enter BULKRATE as a coupon code to manually activate the rates. You can always opt not to use the bulk rates. If you are looking for wholesale prices please feel free to contact us.

Almost useless but ...

Posted by speiss on 3/13/2010
Involvement: Expert (understands the inner workings) - Ownership: 1 week to 1 month

Overall Rating:

Pros: Good way to generate power when every other source is unavailable.
 
Cons: Voltage is unregulated - the faster you spin the more voltage you will get - don't fry your device
Extremely weak construction - within first few normal spins it broke. The case holders where shattered in pieces.
Gears inside the chargers are not running smoothly.
 
Other Thoughts:  
Bottomline: At first thought it seems like almost useless because the case shattered in pieces means you cannot use it any more. On other thought I will try to use the generator and electronics to make use of it. Maybe build stronger case or get power from wind.

Pros: Built quality is slightly better thn I expected. It is small to hand but zou can hold it quite well because of its shape. Engine works fine but I tested it just for several minutes now.

Cons: It was delivered with other items in package but this charger was packaged just in plastic box.

Other Thoughts: I will see how long the black lever will live, it seems little bit fragile. Body of this toy seems more stable.

Bottomline: nothing

Flimsy, may damage batteries

Pros: This device is very nice *in concept*.
 
Cons: It is very poorly built: after my second time using it, the plastic casing cracked around the well of one of the two screws holding it together. The gears rely entirely on the case to be held in place, so if you spin the handle too hard, you place too much stress on the case. I had to glue it back together.
The power it puts out may be unregulated:
after using this device a few times, I have noticed that the battery life on my cell phone (LG Dare) is about half of what it used to be. This is a pretty sudden drop. Closer inspection of the battery found it to be slightly swollen in the middle. I think one or two of the cells inside may have burst because of charging with this device.
 
Other Thoughts:  
Bottomline: Buyer beware! While I thought I should be able to get a good dynamo charger for this price, this isn't the one.

Pros: I reckon there is NO pro's with this device at all.

Cons: i bought this usb hand crank for fun but i still thought it would work fairly well, but when i recieved it i plugged a iphone usb cable into it and tried charging my iphone i spun the handle round and round but it would charge and after about 10 minutes of spinning i started to smell smoke from the actualy device itself, unless this a defective product then this is complete waste of money.

Bottomline: While i was shopping online it looked like a good buy for emergencies but when i received this package and tested this device out for myself i found out it is a waste of time and money it wasnt worth ordering and waiting for it.
