I have a Windows tablet with a charger which crapped out. The old charger was 12V / 1.5A - fairly standard but it had a rare tiny pin connector. Rather than buy a new charger, I decided to cannibalise another 12V / 1.5A charger I had with a different connector. I snipped the wires on both chargers about mid way, and rewired them using a block of those plastic wire connectors surrounded by some insulating tape. Not pretty, but secure. The charger works fine.
Recently, I read that a cheap, two pin fitting LED bulb could be highly dangerous. Because the bulb can be inserted either way, the capacitive dropper which protects you from the live wire could easily be connected to the neutral, leaving the live unprotected. A 50/50 chance. While I do steer clear of these cheap LED bulbs, it got me thinking about my DIY charger.
- Is there a risk that I've created a dangerous charger?
- Is there a 50/50 chance the connector pin is live? If so, is there a safe way to rectify it or should I chuck it and just buy a new one?
- Or, since the charger outputs 12V does it mean that it's safe enough?
