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.

Involvement Level: Expert (understands the inner workings)
Pros: Small dimensions of PCB. Coil should be the same size everywhere since its size is tuned for operating frequency. Has two LEDs, orange lights all the time Blue lights when the phone is nearby and charging can begin. From my tests, the phone is recognized and starts charging when it is placed 9mm from the top of the coil (see my pics). Current consumption compared to distance: phone on the top of the coil: 0,8A phone 9mm from the top of the coil: 1A phone 11mm from the top of the coil: 1,2A phone 13mm from the top of the coil: 1,35A
Cons: Short wires from the coil, could be much longer, no other cons. Phone must be closer (max 1cm) from the coil to start charging, after that, You can move phone to previously mentioned 13mm and still charging.
Other: I was using Samsung Galaxy S4 with wireless cover, sô this was my "reference" :) It also has solder pads near the micro USB port to solder wires. I will buy more.
