Only after that is resolved, might it be worth investigating the second behaviour.     1. Those charger boards from Ebay cannot be relied upon to work (a) correctly, and (b) safely. They typically appear to use the TP4056 ( allegedly based on the Linear Technology LTC4056). The TP4056 has itself been cloned, with some not stopping charging the battery at the correct voltage, for example. Here is one engineer's experiences, with comments from other people where TP4056 chips (or clones) didn't behave as expected: http://jimlaurwilliams.org/wordpress/?p=4731     2. Even if that...

http://jestineyong.com/four-meters-to-test-tank-capacitor-ol/ I've just have one same issue/case. I think it would be interesting to know why my adapter with correct output voltage (ab 10.4V for 9V adapter no load). But when I plug it to load (a router) then nothing work (capacitor do not charge). So tearing my hair some hours until I try another adapter. http://www.ecircuitcenter.com/Circuits/smps_pwr1/smps_pwr1.htm

I simply replace the power transistor H77 with same part (B772) and the buck converter 34063. Detail about part number and location I will update later.
