Under $1 Power Supply for I MAX B6 Charger

Hi everyone. This is my first instructable. And I hope you will like it. I recently brought an I Max B6 charger from Aliexpress. It runs off a 11-18 VDC supply which can be had from a AC-DC adapter. I didn't have one, so I decided to make it myself.

I had few unused faulty mobile cellphone chargers lying around. These have an output of around 6 volts DC. Needed some minor repairs and they were all set.

I just connected the charger output in series so to add up the voltage (around 12 VDC). I removed input legs of one charger and connected it to the input of the other charger in parallel so that both receive 220 VAC. I joined the two chargers with electrical tape to make a single assembly, though there are better ways to keep them together. The output will be obtained through wires (red and black), thanks to alligator clips that come with the IMAX charger.

Finally, when I plugged it in ... and lo... both chargers are working (pilot lamps, one red other green are on). I tested the output voltage and current which were 12.07 VDC and 0.701 A. I hope this runs my I MAX. Let's see in the next step...

Finally, I simply connected my I MAX B6 charger to the assembly and....... it worked...Great..
