USB Charger Stand (Making My Own) ?
Cellulars, Kindle, Nook, Yadda. Too many gizmos to count, it seems like. And the ebooks much prefer gentle charge rates (current limiters). Then there is Mexican electricity. In a fit of optimism, I p...

Well the Meanwell is ideally suited to take a scad of 20mm MOV's and 190 volt ptp TVS bi directional diodes. Line to Neutral and Line to earth ground. The internals laugh at 80 volts and 150 volts. So that aspect may be covered pretty well. USB charging duty for a power supply that big is a real shovel-leaner.
Press a button start a timed charge. So little wattage a wire-wound resistor will last forever for current limiting. Remember whatever I charge has it's own version of "what's for dinner" control. The timer is nothing more than an automatic "Unplug Now" disconnect.
And I, not some idiot sets the charging limit voltage.

Both Eduardo and Orlando have identical Craftsman 12-volt lithium drills. Eduardo lost his charger when he moved. He asked me to recharge his battery with my lab power supply. So I did. Gently. The battery charge hit a brick wall just like an AGM battery. Only at 12.17 volts. I gave the battery back. a few days later came the feedback...
My drill has NEVER been this powerful when I charged with the Craftsman charger.
Orlando charged his battery then gave it to me. Charged? According to whose Hookah? "Now it will almost break my wrist" reported Orlando after a ramped gentle charge.
Milliamps, time, temperature were all carefully controlled.
Why do I get the feeling I am running into the same idiocy as I see with new lead acid battery chargers? Show me HOW or where to find clear statements of Li-Ion management that spells out dangers of "The ease in which small Li-Ion are overcharged to the point of endangering lifespan".
