I bought this to see just how much of a charger you get for a mere £5. It turns out that it's actually quite nice inside and has good slow-charger (200mA) functionality.
It has a cut-off timer that may be as short as just 10 hours so it's probably best suited to cells under 2000mAh or for topping up larger cells. That timer section can be bypassed internally though.

Very Nice
You are an encyclopedia of electronics, Clive.
I'm in awe of your knowledge. 👍
"So let's H O I N K this out"
-Big Clive, 2019
I have an UltraFire 18650 with… wait for it….. 9800Mah! Tested at 72Mah.
Honestly whenever I find a shitty NiMh that I've had since I was about 7, of which there are quite a few, and it doesn't take a charge at all, I stick it on the bench power supply, and blast it with 5V and shove an amp through it for a couple seconds, and that seems to burn off whatever oxides are present causing high impedance. I'm sure it shortens cell capacity but honestly those old ones I usually only use in stuff like television remotes. Often I'll ask friends if they have any old rechargeables they were going to recycle and I'll take them, nuke them with the 5V, then get a few more years of basic operation out of them before finally putting them out to pasture.
i like my chargers the way i like my girlfriends: not too smart and not pretending to be smarter than they are
No eighth vent to protect the power input section from spills etc.
What happens if you put a dummy battery next to a single battery to get it to charge?

I love your catch-phrase "but that's OK". Is there any circumstance where you would not use it?"I've just cut my leg off – but that's OK"
ever heard of NI-MH D cells?
