Wireless Super Capacitor Charger Set
with super capacitors & AC Adapter MUST SEE
This listing is for a fully assembled wireless super capacitor charger set that includes a wireless power transmitter, a 12v 1A AC adapter, a wireless power receiver, two 60f 2.7v super capacitors, and a charger PCB. Everything comes assembled as seen in the video. You just need to watch the video to see how it works! The shipping cost of $7.80 will get you air shipping via Canada post to the US (Small packet Air). We will also be selling these in kit form for a few dollars less when I am able to make an assembly video.
How It Works:
The 12v 1A AC adapter applies 12v to the transmitter coil set. The transmitter coil set will take very little current (<10mA) when the receiver coil is not within a close proximity to the transmitter coil. The receiver coil is soldered to a custom PCB that includes an on/off switch for the charge, a current limiting resistor, and 2x 60f 2.7v super capacitors. When you plug in your AC adapter to power the transmitter, turn the switch on the receiver board to the ON position, and place the transmitter and receiver coils together. Power will couple between the two as long as they are parallel and within a proximity of about 1.5cm or less. The closer they are, the more power can be coupled. The current limiting resistor is rated for 18 ohms at 5W, which means that when the capacitors start to charge from 0v, they will be charging at roughly 278mA. The resistor can be substituted for a 10 ohm 5W resistor if you have one. This will offer a charge of roughly 500mA MAX, but such power will only transfer at a maximum when the coils are very close to one another.
There are two leads on the side of the main capacitor bank PCB labelled +CAP & -CAP. The +CAP lead is your positive super capacitor bank lead. The -CAP is your DC Ground lead. These leads can be used to test charge voltage, or to splice your capacitor power to an external project. In the above video, I use a multimeter to measure charge voltage. when your capacitor bank is charged to your satisfaction, make sure to turn the switch on the capacitor bank PCB to the OFF position to ensure that there is no back-powering from the capacitor bank through to the wireless receiver. This is very important, as the power on your cap bank will eventually bleed off if you forget to place this switch into the OFF position after charging.
The capacitor bank that is included with this set is rated for 30 farads @ 5.4v (2x 60 farad 2.7v capacitors in series). If after reading this information, and watching the above video, you still have questions, please do not hesitate to ask.
