Yes that fits. Can you put a bit more load on it ? A laptop in parallel perhaps ?<br>

Pure guess but some laptop supplies require a minimum current draw. If not, they power up, find there isn't enough draw then turn off and try again. What time interval are we talking about ?</div>

<div>I did check contact between the leads on the back of the tip and the contacts where the power jack are soldered inside the 4ms pod with my multimeter continuity setting and it seems to be making a connection. Maybe the 0.4mm difference
is negligible?<br>
Also, the on and off isn’t random like a bad connection, but very regular.<br>
<br>
Does this “motor boating” idea make sense? It is a 90w power supply and the 4ms requires minimum 20w<br>
