Most minimalist charger yet (Patreon)

Different eBay battery charger - with schematic

Another eBay delight to explore. It's actually available as a three way and four way version at the same price. The circuitry will be common to both of them though, as the number of cells is irrelevant. The neatest thing about this slightly shady charger is the clever way they have minimised cost and manufacturing time by combining the circuitry and the connector onto one PCB. I'm not sure if this charger classifies as the worst yet, since an earlier version smashed huge amounts of current through its indicator LEDs. But this is a close contender. It's not even worth hacking.
