Good size for traveling. Cheap product to charge different electronics with connection to USB.
Not charging with ordinary alkaline batteries (duracel). I used philips rechargeable batteries 2100 mAh and connect to my HTC Desire smartphone. They just charge it about 40 percent, and then began to rapidly discharge smartphone to 0 percent. I've tried other rechargeable batteries with a capacity of 2500 mAh and the smartphone is loaded only about 4 percent, and then began to discharge my smartphone.
Should be use to a high quality rechargeable batteries. Not suitable to charge the smartphone even if it seems so.
It's only for charging small devices with low capacity.
